In this blog we are going to talk about trends in the power industry and how they may affect utilities.  One of the ongoing themes of this blog is that to be leaders in the field, we need to be cognizant of what others are doing and how those actions might affect utility operations.  Power is a big cost for utilities – often 10-15% of the total operations costs where a lot of pumping is involved. In most communities, the utility system is among the largest consumers of power, which is why many utilities have load control agreements in place – power companies can off-load power demands by having the utilities go to onsite generators.  Our community’s building account for 70% or more of local energy use.

The need for power is expanding, albeit at a lower rate that population growth in many communities.  This is because new building construction measures tend to insulate better and install more energy efficient equipment.  Power companies often will subsidize these improvements to reduce the need for more expensive plant expansions.  Where expansions are needed, purchase/transfer agreements or renewables are often a convenient answer.

But long-term we are seeing that the power industry is changing in other ways too.  Already we see a migration away from coal for power generation.  This was occurring before the new regulations were in place for carbon dioxide.  Certain utility companies like NextEra, the largest wind and solar power generator in the US, and the parent of Florida Power and Light, have reduced greenhouse gas emissions from their plants by converting to other sources like combined heat and power (CHP), and increasing efficiency.  The typical oil or coal power plant is 30-35% efficient, while the newer gas turbine systems are up to 45% efficient.  That makes a big difference in costs as well as emissions when gas emissions are half the coal and oil emissions.  NextEra is well placed for carbon trading, a concept some fight, but the US had been emission trading since the early 1990s, so carbon trading markets are already in place.  The only thing needed is the regulations to put them into play.  Buy that NextEra stock now and hope for carbon trading!

But NextEra is not the only likely winner under this carbon trading scenario.  ExxonMobile is big into gas, Exelon is big in the nuclear power industry, Siemens and General Electric, which make wind and gas turbines, are also likely to see growth.  All have poised themselves years ago as the impact of carbon dioxide becomes more apparent.  Most of the industry executives acknowledge climate issues and recognize that people will expect the industry to do its part (the Koch brothers aside).  Many power generators like ConEd and FPL are making changes as well, in advance of the regulatory requirements to do so.  They see it as good business.  They also see it as a means to make more power at a given facility (by increasing efficiency) while reducing water use.  Water use can be a limiting factor, so we will discuss that in a couple days…

In the last blog we discussed 10 planning steps for sea level rises.  When planning 50-100 years other factors can come into play as well.  As a result, to allow flexibility in the analysis due to the range of increases within the different time periods, an approach that uses incremental increases of 1, 2, and 3 feet of SLR is suggested.  Hence infrastructure is built to meet milestones, not arbitrary dates lessening the potential for stranded assets.. The increments can work as threshold values in planning considerations in terms of allowing planners the ability to know ahead of time where the next set of vulnerable areas will be to allow a for proactive response approach that can be matched to the observed future sea levels.

But prior to developing infrastructure plans, the local community needs to define an acceptable level of service (LOS) for the community. A level service would indicate how often it is acceptable for flooding to occur in a community on an annual basis.  1% is 4 days per years and for a place like Miami Beach, this is nearly 2 ft NAVD88, well above the mean high tide.  The failure to establish an acceptable LOS is often the cause of failure or loss of confidence in a plan at a later point in time.  The effects of SLR of the level of service should be used to update the mapping to demonstrate how the level of service changes, so that a long-term LOS can be defined and used for near-term planning.

With the LOS known, the vulnerability assessment is developed using a GIS based map of topography and the groundwater levels associated with wet and dry season water levels.  LiDAR is a useful tool that may be available at very high resolution in coastal areas.  Topographic maps must be “ground-truthed” by tying it to local benchmarks and transportation plans.  USGS groundwater and NOAA tidal data from local monitoring stations to correlate with the groundwater information. Based on the results of these efforts, the GIS-based mapping will provide areas of likely flooding.

GIS map should be updated with layers of information for water mains, sewer mains, canals, catch basins, weirs and stormwater facilities.  Updating with critical infrastructure will provide a view of vulnerability of critical infrastructure that will be funded by the public sector. Ultimately policy makers will need more information to prioritize the needed improvements.  For example, a major goal may be to reduce Economic Vulnerability.  This means identifying where economic activity occurs and potential jobs.  At-risk populations, valuable property (tax base) and emergency response may be drivers, which means data from other sources should be added.

The next step is to analyze vulnerability spatially, by overlaying development priorities with expected climate change on GIS maps to identify hotspots where adaptation activities should be focused. This effort includes identification of the critical data gaps which, when filled, will enable more precise identification of at risk infrastructure and predictions of impacts on physical infrastructure and on communities. The final deliverable will include descriptions of the recommended concepts including schematics, cost estimates, and implementation plan.

So why go through all this.  Let’s go back to the beginning.  It has to do with community confidence in its leaders.  Resident look at whether their property will be protected.  Businesses look at long-term viability when making decisions about relocating enterprises.  The insurance industry, which has traditionally been focused on a one year vision of risk, is beginning to discuss long-term risks and not insuring property rebuild is risk-prone areas.  That will affect how bankers look at lending practices, which likely will decrease property values.  Hence it is in the community’s interests to develop a planning framework to adapt to sea level rise and protect vulnerable infrastructure through a long-term plan.  Plan or….

Sea Level Rise Planning – Part 1

The rainy season has sort-of started in south Florida and with it comes flooding and discussions of the falls end of season and concurrent high, high tides for the year, flooding and the impact of sea level rise on low-lying areas.  Much focus has been spent on the causes of sea level rise and the potential flooding caused by same.  However the flooding can be used as a surrogate to impacts to the social and economic base of the community.  By performing vulnerability assessments, coastal areas can begin planning for the impacts of climate change in order to safeguard their community’s social, cultural, environmental and economic resources. Policies need to focus on both mitigation and adaptation strategies, essentially, the causes and effects of climate change. Policy formulation should be based on sound science, realizing that policy decisions will be made and administered at the local level to better engage the community and formulate local decisions.

Making long-term decisions will be important.  Businesses look at long-term viability when making decisions about relocating enterprises.  The insurance industry, which has traditionally been focused on a one year vision of risk, is beginning to discuss long-term risks and not insuring property rebuild is risk-prone areas.  That will affect how bankers look at lending practices, which likely will decrease property values.  Hence it is in the community’s interests to develop a planning framework to adapt to sea level rise and protect vulnerable infrastructure through a long-term plan.

While uncertainties in the scale, timing and location of climate change impacts can make decision-making difficult, response strategies can be effective if planning is initiated early on. Because vulnerability can never be estimated with great accuracy due to uncertainty in the rate of warming, deglaciation and other factors, the conventional anticipation approach should be replaced or supplemented with one that recognizes the importance of building resiliency.  The objectives of the research were to develop a method for planning for sea level rise, and providing a means to prioritize improvements at the appropriate time.  In addition the goals were to provide guidance in developing a means to prioritize infrastructure to maximize benefit to the community by prioritizing economic and social impacts.

Adaptation planning must merge scientific understanding with political and intuitional capacity on an appropriate scale and horizon.  According to Mukheibir and Ziervogel (2007), there are 10 steps to consider when creating an adaptation strategy on the municipal level.  To summarize, these are as follows:

  1. Assess current climate trends and future projections for the region (defining the science).
  2. Undertake a preliminary vulnerability assessment of the community and communicate results through vulnerability maps (using GIS and other tools).
  3. Analyze vulnerability spatially, by overlaying development priorities with expected climate change on GIS maps to identify hotspots where adaptation activities should be focused.
  4. Survey current strategic plans and development priorities to reduce redundancy and understand institutional capacity.
  5. Develop an adaptation strategy that focuses on highly vulnerable areas. Make sure the strategy offers a range of adaptation actions that are appropriate to the local context.
  6. Prioritize adaptation actions using tools such as multi-criteria analysis (MCA), cost-benefit analysis (CBA) and/or social accounting matrices (SAM).
  7. Develop a document which covers the scope, design and budget of such actions (what they call a Municipal Adaptation Plan (MAP)).
  8. Engage stakeholders and decision-makers to build political support. Implement the interventions prioritized in the MAP.
  9. Monitor and evaluate the interventions on an ongoing basis.
  10. Regularly review and modify the plans at predefined intervals.

 

The strengths of this framework are the initial focus on location-specific science, the use of both economic and social evaluation criteria, and the notion that the plan is not a fixed document, but rather a process that evolves in harmony with a changing environment.  The final two steps occur at regular intervals by the community with associated adjustments made.  The next question is how to develop the data and priorities.

Economic Challenges or Challenges to Economics?

As you are aware, I have several hobbies and interest, and economics is one of them.  Economics has theorists from many different viewpoints, and the commonality among them is that there is no “school of thought” that explains everything.  So new schools get developed to explain the current events, or old ones that were discredits are resuscitated, but unfortunately we too often neglect the past, or at least the examples of the past.  Too often the obvious gets ignored.  For example, we cave money because we know there will be ups and downs.  Individual do it, so why don’t governments?  We know that we will pay for a product we need.  Demand drives the price.  If more people want it, the price goes up.  Been that way for…. ever maybe?  So in my recent reading I came across several musing that keep getting talked about by political pundits, but may be they are not what they appear to be.  So let’s take a look at a couple of these that might just affect us….

 

Is supply side economics is a myth developed by corporate economists to argue for lower taxes.  The concept is to give tax breaks to encourage manufacturers and businesses to produce more product which will reduce costs.  You know this is patently false.  Try selling your reclaimed water at a discount (or give it away) when it is raining.  Demand drives the economy, not supply.  Every economics student learns this in economics 101.  The supply side economics school developed as a means to explain stagflation in the 1970s. The idea what to give tax cuts to those who invested, so they would invest more to make new products, which would trickle down to the rest of us.  Still doesn’t work.  Why?  What they ignored was that the US industrial sector had saturated the US economy with goods and could not grow without new sectors to sell to.  Hence the push on Nixon to open up China to foreign trade and investment.  But opening foreign markets was great, except they could not afford our products.  So we had to make the products there, increase local wages so they could buy the products, and still shipped products back at a cheaper cost that to build them in America.  The idea is not new – recall Henry Ford set up the assembly line to cuts costs to allow him to increase wages so his workers could buy his cars.  The obvious question is when we saturate China, then what?  Africa?  Then what?  The economy cannot grow faster than the increase in population.  So why does supply side economics keep getting traction?  Did we mention those tax cuts….

 

To the big fashion in Germany and the EU is austerity.  Austerity is an economic idea that never seems to die despite very limited success and many, many failures.  It sounds great – cut costs and balance the budget while cutting revenues (income).  Ok, so let’s see how that works in your household – you quit your middle class job and take a minimum wage job.  You cut your expenses.  Except you can’t sell your house without a loss (and you do not have the cash to make up the difference) and you need your car to get to your new job.  But austerity says that if you eat rice, beans, cereal and Ramen noodles, you will soon be far better off than you are now.  No one will suffer.   Do you believe it?  Do you wonder why the Greeks and Irish are not doing so well today and why people are restless?  They used to devalue their currency, but the Euro prevents this.  They do not have away out.  Meanwhile Iceland devalued currency, let the banks fail, took over the bank assets, and are doing much better.  Austerity was not the option…. Just saying…  And who suffers the most?  Not the high income folks.

 

Tax cuts stimulate the economy.  Sounds great.  But, from 1944 to 1963, the income tax rate on the highest earning bracket in 1960 was 90% over $200,000.  Yes 90%!   The economy was great.  The middle class was born.  House ownerships jumped.  Education was up.  The economy in the 1970s stagnated after we cut tax rates.  We cut the income tax rate in the 1980s, but raised other taxes, and things improved, but then declined.  The economy improved after the Bush tax hike in 1991. It did not improve after the Bush tax cuts in 2001.  Interesting in their book Presimetrics, Mike Kimel and Mike Kanell noted that higher taxes seem to correlate with a better economy.  Is it because investors can’t sell stock so easily when they made a profit so corporations can count of investments longer?  Or is it that the increase in revenues allows the federal government to invest in more research and development that further stimulates the economy?  Did we mention the tax cuts favor the wealthy?

 

The moral of the story is that utility managers cannot ignore the economic realities around them.  We cannot be trapped by the musings of people who have hidden agendas, which means that our understanding of the way things are must extend beyond the utility itself.  The economy, economics, monetary policy, tax policy, demographics and change are areas that utility managers need to be current on.  Engineers and managers often understand these issues easily (most are mathematical) but we tend to focus only in out areas.  We need to become educated.  Recall the earlier blog where I noted the city manager who realized later that the reason elected officials tended to bad alternatives was they were being lobbied to approve the poorer options because their clients could make money from it.  You know many ideas that will be lobbied to elected officials and business people in the future.  You need to become educated on these ideas and how they affect your utility.  You know that rates that are too low will not increase revenues.  You know you need to expand sales when possible, perhaps serving new areas, and making the investments for same.  You know that not spending money will only increase the risk of failure in the system.  You know that not increasing pay will disenfranchise employees.  Prepare for these assaults so you can lead your utility down the proper path. 

Sea Level Rise, SE Florida Style

There has been significant discussion about the potential impacts of climate change on the world:  more intense rainfall events, more severe thunderstorms and tropical cyclones, droughts, loss of glacial ice and storage, increased demand for crop irrigation.  However for much of the State of Florida, and for much of the coastal United States east of the Rio Grande River, the climate issue that is most likely to create significant risk to health and economic activity is sea-level rise.  Data gathered by NOAA from multiple sites indicates that sea level rise is occurring, and has been for over 100 years. About 8 inches since 1930.

The impact of climate change on Florida is two-fold – Florida often is water-supply limited as topography limits the ability to store excess precipitation for water use during the dry periods and sea level rise will exacerbate local flooding.  The highly engineered stormwater drainage system of canals and control structures has effectively enabled management of water tables and saltwater intrusion by gravity. The advent of sea-level rise will present new challenges, because the water table is currently maintained at the highest possible levels to counter saltwater intrusion, while limiting flood risk in southeast Florida’s low-lying terrain and providing for water supplies.  As sea level rises, the water will not flow by gravity, which disrupts that balance struck between flood risk and water supply availability in the canal system.

Occasional flooding is not new to Florida, but the increasing frequency we currently experience is related to sea level rise, not just along the coast, but for large expanses of developed property inland due to topography and groundwater levels.  As a result, the challenge for water managers in the state, especially in southeast Florida, is to control the groundwater table, because control of the water table is essential to prevent flooding of the low terrain.

The issue is not lost on local governments in south Florida nor on the educational institutions in the area.  Florida Universities are studying the impacts to the region to identify ways in which we can mitigate, respond to and adapt to these changes. My university, Florida Atlantic University, is located in this vulnerable part of the State has been proactive in partnership with the Four County Compact in addressing these issues and we have now joined with other Universities in the State to form the Florida Climate Institute, a consortium working with state and federal agencies to address the multiple challenges and opportunities facing this State. FAU in particular, has been proactive in developing tools to evaluate risk and identify adaptation strategies to protect local and regional infrastructure and property. 

Our efforts have included using high resolution NOAA data to map topography at the +/- 6 inch level, combined that topography with mapping of infrastructure and groundwater, to identify vulnerable areas throughout Broward, Miami-Dade and Monroe Counties, as well as initiated projects in Palm Beach County and other coastal regions throughout the state.  By identifying vulnerability based on sea level changes, the timing and tools for adaptation can be designed and funded to insure a “no-regrets” strategy that neither accelerates nor delays infrastructure beyond its need. 

While we have all heard the discussion of an estimated two to three feet if sea level rise is anticipated by 2100; sea level rise is a slow, albeit permanent change to our environment.  The slow part allows us to make informed decisions about adaptation strategies that may prove useful in the long term as well as the short term.  Of prime importance is the need to plan for these needs 50 or more years out so that we do not increase our exposure to risk.  Keeping development out of low lying areas, redeveloping pumping and piping systems with change in mind and reserving areas where major efforts will need to be undertaken, is important to the public interest and will affect private business, tourism and homeowners.  Sea level rise is already a problem for many low lying areas such as Miami Beach, Fort Lauderdale, Hollywood, and other coastal communities. It will be an incremental problem creeping up on us for the rest of the century and beyond.

The lowest lying areas are the roadways, which are also the location of electrical, water, sewer, phone and drainage infrastructure.  Fortunately given the current Federally funded special imagery and NOAA data systems we are able to predict pretty accurately where flooding will occur.  Linking that information with detailed projections of sea level rise impacts we can  map vulnerable areas and build adaptive measures into every action and plan we undertake.  But the impacts are not only on the coast. Sea level affects ground water table levels and with our intense rainfall areas far inland can be flooded, even subject to long term inundation.  Water levels are rising and will continue to rise as groundwater rises concurrently with sea level. Add the impact summer rains and dealing with water becomes a major priority. Figures 1 and 2 outline the roadway network degradation at present, 1, 2, and 3 ft of sea level rise.  The figures demonstrate that a major, underestimated amount of property is vulnerable on the western edge of the developed areas because the elevations are decreasing as one moves west from I95.

While time will impact our environment, there are three options to address the change:

 

  • Protect infrastructure from the impacts of climate change
  • Adapt to the changes, and
  • In the worst case retreat from the change.

 Retreat does not need to be considered in the short or medium term.  South Florida has developed in the last 100 years and there will be well over 100 years of life left.  As a result, the best option is adaptation.  Adaptation takes different forms depending on location.  I have developed a toolbox of options that can be applied to address these adaptation demands, resulting in an approach that will need a more managed integrated water system, more operations and inevitably more dollars.  For example we can install more coastal salinity structures, raise road beds, abandon some local roads, increase storm water pumping, add storm water retention etc. to address many of the problems.  The technology is available today.

Much of the actual needs are local, but the problem is regional and requires a concerted effort of federal, state and local agencies and the private sector to address the scales of the problem.  A community can address the local problems, but the regional canals, barriers, etc., are beyond the scope of individual agencies.  Collaboration and discussion are needed. 

The needs will be large – in the tens of billions.  But there are two things in south Florida’s favor – time and money.  The expenditures are over many, many years.  Most important in the near term need is the early planning and identification of critical components of infrastructure and policy needs and timing for same.  That is what FAU does best.  At risk are nearly 6 million of Floridians their economy and lifestyle, $3.7 trillion in property (2012) in south east Florida alone and a $260 billion annual economy.  All of these are expected to continue to increase assuming the appropriate plans are made to adapt to the changing sea level.  Protection of the area for the next 100-150 years is achievable as long as we have the science, the understanding and the will to do it.  Plan now, and over the rest of this century starting now we can raise those billions of dollars needed.

 

Top Ten Reasons to Deny Climate Change is Occurring in no Particular Order

I had to share this, from a nonscientific survey of people adamantly opposed to any consideration of changes to our climate:

1. I can’t do anything about it so I don’t care about it
2. People can’t alter what is happening with the earth because it is too big
3. It’s natural, so we can’t do anything about it
4. It’s not an issue now, so it’s somebody else’s future problem
5. The science is inconclusive so why do anything yet. Let’s see what happens
6. Trying to address it will cut jobs
7. We won’t be competitive (i.e our profits will drop)
8. It requires changing our business model (energy)
9. If we talk about it no one will develop in our community
10. Costs too much

I had to post this as many of you will have comments. But before you do, these about this a minute……

The first five are based on no facts, but a desire to ignore the issue entirely. The second five are more poignant because aren’t these pretty much the same arguments to deny the need to correct water pollution concerns in the 1930s? Or 1950s? Or even 1970s? Or even today with hog farms, frack water, acid mine waste, coal dust slurries, etc.? Or actually pretty much every regulation? I seem to recall Tom Delay making this argument when he was in Congress before he was indicted.

Now think about the Clean Water Act, Clean Air Act, Safe Drinking Water Act, and others. These regulations are designed to correct ills of the past that were simply ignored due to the first five arguments above, ignoring the fact that prevention is always less costly than cleanup afterward. To we pass regulations to clean up problems and protect the public health going forward. Otherwise why have a regulation?

So let’s talk about that jobs impact. The reason is that after the passage of these regulations, didn’t the number of professional jobs (like civil and environmental engineers, environmental and other scientists – STEM jobs) increase? Isn’t increasing STEM jobs a priority? So won’t dealing with climate issue perhaps create a similar increase in STEM jobs? Yes, costs for water increased and the cost for the effects of climate changes will cost money, but don’t these challenges create opportunities? Isn’t this akin to dealing with problems with development from the past? Just asking…..

Inheriting Infrastructure?

At a recent conference I was listening to a presentation by the Army Corps of Engineers explaining the investments made over the last 80 years.  Subsequent presentations discussed that the need to reinvest in infrastructure appears to be about 3.6% of infrastructure value per year, but that the US is spending about 2.4%.  The best condition of our infrastructure was in the 1980s, but decreases in reinvestment due to funding limitations has caused an ongoing decline in infrastructure value, which is why the ASCE report cards show most of our infrastructure at the D or D- level.  It is getting old and it needs repair and replacement.  You would rarely buy a house, never maintain it, and expect it to live in it without problems for 50 years.  Roofs leak, pipes need replacing, mechanical equipment, lights and appliances fail.  It is the cost of owning a home. You have to update.  Most times the new equipment is more efficient that the old stuff, saving money.  So why do we do this with infrastructure?

More interesting was the response to how some of these agencies may deal with this backlog of deferred maintenance.  So far I have heard the Corps, state transportation agencies, state land agencies and another federal government say that they are figuring out means to prioritize the assets and dispose of those not needed.  So let’s see how that would work and I kid you not, these are suggestions:

  •          Abandon state roadways and let local governments deal with them.  Of course these are roads that are challenged – like they flood constantly and the cost to raise them is cost prohibitive, but the city has development along the corridor
  •          The state has low value wetlands they will donate to the underlying county – not that you can do anything with this land- it is not developable, but needs to be monitored and maintained
  •          There is a waterway that has leaking dikes but serves very few people.  Let’s give it to the local community as they are the only ones who use it.
  •          We have monitoring equipment, but it really provides more information locally that regionally, so let’s give it to them 

Hey I like the idea of giving, but seriously, how does the “recipient” deal with this problem.  The low value assets are low value because they serve limited people and are deemed to have little economic or useful value or are too expensive to maintain.  So what does the recipient do with it?  They do not have nearly the resources that larger governmental entities have, and if the big guys cannot find the money, will locals?  Are we just kicking the problem to the next guy?  Sounds like used car sales to me.

It sounds suspiciously like the argument I have heard several times from a city manager who talked about cutting the size of local government, only what he did was contract with other entities to do the services, which means cuts in employees for his city, but the cost is just transferred to another entity.  The rate/taxpayers will foot the bill unless the service is completely discontinued.  In his case, they all paid more.

The State of Florida and the federal government have both cut employees and both contract heavily for services that never used to be contracted.  There is a whole industry of contracting for government work that used to be done in-house.  In other words, they privatized portions of the operations.  But did the cost of government decrease in either case?  No. 

So going back to the initial question – will governments abandon infrastructure?  The answer appears to be yes, but the problem is that that infrastructure IS being used by people so the reality of full abandonment is impossible.  The result will be that underlying local entities will be stuck with the bill.  Planning is needed.  “Fail to plan = Plan to fail” as my friend Albert says.  We need to identify where these “gifts” may occur and identify a means to deal with the inherent obligation that goes with them.  For water and sewer utilities, waterways and roadways are of particular concern, but so could watersheds and well sites. 

 

Infrastructure Replacement

We all know that our infrastructure is deteriorating.  Deferred maintenance increases the risk of system failure. The need for capital reinvestment within the utility industry has historically been very low. As a result, in its “2013 Report Card for America’s Infrastructure,” the American Society of Civil Engineers assigned a grade of “D” to America’s drinking water systems, citing billions of dollars of annual funding shortfalls to replace aging facilities near the end of their useful lives and to comply with existing future federal water regulations (ASCE, 2013).  AWWA estimates that investments of at least $1 trillion are needed over the next 25 years.

While a pay-as-you-go capital funding seems like the best way to go, that is difficult to accomplish with the large outlays needed to upgrade the infrastructure system and the controls on rates often exercised by local officials.  As a result, borrowing is required and the condition of infrastructure and the lack of reserves are a part of how the utility is viewed by those who lend monies.   Utility managers need to understand how the lending agencies evaluate risk. 

Lenders use many tests.  Among them are: whether the utility’s annual depreciation expense is used of accumulated as reinvestment in the system, whether adequate reserves are present, whether  annual capital spending that is below the amount of annual depreciation and the amount of revenues in excess of projected debt (debt service coverage).  The target debt service coverage may depend upon the requirements of the underwriter, the rating agencies and the investors.  Debt service coverage could be as low as 15% or as high as 50%.  In 2012, the median all-in annual debt service coverage excluding connection fees for utilities rated “AAA” by Fitch Ratings was 220%, while the median for AA-rated and A-rated utilities was 180% and 140%, respectively. (Fitch, 2012).  

A working capital target of 90 days of rate revenue is a minimum, but since 2008, more is likely to be required depending on the size of the system and the history of revenues.  Where the revenues were stable despite 2008, less may be required.  For those utilities that suffered major decreases, reserves should be far larger – perhaps a year or more.  Other criteria that could be used to evaluate the projects when borrowing money include public health and safety, regulatory compliance, system reliability, the risk and consequences of asset failure, redundancy, community/customer benefit  and sustainability. At the same time, the expectation is that  the utility systems that retain all monies in the system to be utilized to improve the system and pay for debt service, except those used  for the purchase of indirect services from the General Fund that are justified with indirect cost studies. 

 

Despite the above, rate are an issue.  Fitch Ratings has indicated that it considers rates for combined water and wastewater service that are higher than 2% of the median household income – or 1% for an individual water or wastewater utility – to be financially burdensome (Fitch, 2012).  The Environmental Protection Agency (EPA) considers that rates for an individual water or wastewater utility that are greater than 2% of median household income may have a high financial impact on customers. (EPA, 1997). Utilities with a stronger financial profile might have residential charges for combined water and wastewater service that are less than or equal to 1.2% of median household income, or less than or equal to 0.6% for an individual water or wastewater utility. All revenues generated through system operations generally must remain within the system and can only be used for lawful purposes of the system.

Canadian utilities employ more formal polices to establish fiscal policies to provide reserves to insure stability in the event of unforeseen circumstances. Reserve targets focus on ensuring liquidity in the event there is an interruption in funding, increased capital costs due to new regulatory requirements or a short term funding emergency – all the issues evaluated by the bankers.  Reserve targets are policy decisions. Benchmarking is an evolving practice within Canadian public sector utilities particularly as it relates to financial planning and capital financing. The benchmarking exercise provides valuable information to help assess fiscal performance, the needs of customers, and provide the tools to help support optimum performance. 

How to Track Reserves

We have spent some time talking about the need to fund and maintain reserves.  I think most people reading this concur but how do you track reserves?  Every public sector utility gets audited annually.  How many people have actually looked at that audit?  Or attend the discussion with the elected officials with the auditors.  Or know how to read it?  This is an important part of our job.  We need to defend the utility and knowing the financial position is part of the defense. 

The annual audit is commonly called the Comprehensive Annual Financial Report of CAFR.  The finance director normally controls the process.  The CAFR is many, many pages long and include information on revenues and expenses, but also a bunch of other things like assets, depreciated assets, transfers to other funds, outstanding long and short term debt, fund balance and reserves.   The CAFR is designed to be a management tool to help with tracking performance of the entity with time.  CAFRs were redesigned by the Governmental Accounting Standards Board (GASB) about 15 years ago to provide more useful information to lenders and oversight agencies.  It was redesigned to help with management, discussion and analysis of the financial position.  The utility director should be a part of this management, discussion and analysis team and should fully understand its contents as it affects the utility. The CAFR should not be viewed simply as a compliance tool to submit and forget about. 

For example, the assets should include the value of all installed infrastructure (fixed) and all mobile equipment (non-fixed) as assets.  The depreciation is the total amount of depreciation, assigned as a straight line, since the acquisition of the assets.  You should always have more than 50% of the asset value remaining.  You should understand outstanding debt and debt plus depreciation should be less than your asset values, otherwise you are underwater with your assets.  You should understand the transfers to other funds and the justification for same.

But the reserves are key.  Some of these reserves may be restricted, which means they are likely impact fees, reserves to cover debt coverage requirements or covenants for repair and replacement of other purposes.  Most utilities do not have a separate repair and replacement reserve, but this would be useful for those capital expenses,  Likewise, operating reserves, for use to balance the budget in lean periods should be identified.  The reporting reserves for rate stabilization should be separate from the operating reserves (usually 1.5 to 3 months) to cover the day-to-day expenses.  An understanding of the value and tracking of these reserves is useful to long and short term decision making by utility managers.  Unfortunately most auditors and most finance director do not make separate reserves and tracking becomes a challenge.  But the utility is an operating entity.  Finance, like purchasing and human resources and support agencies designed to provide service to help accomplish the mission of the operating elements of the utility.  You need the support agencies to provide the necessary information to help your decision-making.  Doubtful your finance director wants to hear this, but really, does the utility operate because the finance department does the work or because the utility does?  Just food for though.

Reserves vs Borrowing

As water and sewer utilities, the public health and safety of our customers is our priority – it is both a legal and moral responsibility. The economic stability and growth of our community depends on reliable services or high quality. The priority is not the same with private business. Private businesses have a fiduciary responsibility to their stockholders, so cutting services will always be preferred to cutting profits. Therein lies the difference and yet the approach is different. Many corporations retain reserves for stability and investment and to protect profits. Many governments retain inadequate reserves which compromises their ability to be stable and protect the public health and safety. Unlike corporations, for government and utilities, expenses are more difficult to change without impacting services that someone is using or expects to use or endangering public health. Our recent economic backdrop indicates that we cannot assume income will increase so we need to reconsider options in dealing with income (revenue) fluctuations. If there are no reserves, when times are lean or economic disruptions occur (and they do regularly), finding funds to make up the difference is a problem. The credit market for governments is not nearly as “easy” to access as it is for people in part because the exposure is much greater. If they can borrow, the rates may be high, meaning greater costs to repay. Reserves are one option, but reserves are a one-time expense and cannot be repeated indefinitely. So if your reserves are not very large, the subsequent years require either raising taxes/rates or cutting costs. An example of the problem is illustrated in Figure 1. In this example the revenues took a big hit in 2009 as a result of the downturn in the economy. Note it has yet to fully return to prior levels as in many utilities. This system had accumulated $5.2 million in reserves form 2000-2008, but has a $5.5 million deficit there after. Reserves only go so far. Eventually the revenues will need to be raised, but the rate shock is far less if you have prudently planned with reserves. You don’t get elected raising rates, but you have a moral responsibility to do so to insure system stability and protection of the public health. So home much is enough for healthy reserves? That is a far more difficult question. In the past 1.5 months of operating reserves was a minimum, and 3 or more months was more common. However, the 2008-2011 economic times should change the model significantly. Many local governments and utilities saw significant revenue drops. Property tax decreases of 50% were not uncommon. It might take 5 to 10 years for those property values to rebound so a ten year need might be required. Sales taxes dropped 30 percent, but those typically bounce back more quickly - 3-5 years. Water and sewer utilities saw decreases of 10-30%, or perhaps more in some tourist destinations. Those revenues may take 3-5 years to rebound as well. Moving money from the utility to the general fund, hampers the situation further. Analysis of the situation, while utility (government) specific, indicates that appropriate reserves to help weather the economic downturns could be years as opposed to months. The conclusion is that governments and utilities should follow the model of trying to stabilize their expenses. Collect reserves. Use them in lean times. Develop a tool to determine the appropriate amounts. Educate local decision-makers and the public. Develop a financial plan that accounts for uncertainty and extreme events that might impact their long-term stability. Take advantage of opportunities and most of all be ready for next time. In other words, plan for that rainy day.
