Dallas Fort-Worth Breathes Easier Following EPA’s Decision On Wise County Ozone Petitions

This commentary was originally posted on EDF’s Texas Clean Air Matters blog.

Just in time for the holidays, the U.S. Environmental Protection Agency (EPA) delivered a valuable gift to residents of the Dallas-Fort Worth area: the promise of stronger protections against the harmful public health and environmental impacts of ground-level ozone (the main component of smog). Specifically, EPA announced on January 7 that it has decided to deny 19 petitions filed by the state of Texas and other parties last summer — all demanding that the agency reverse its determination that Wise County, Texas contributes to high ozone levels in nearby Dallas-Fort Worth (EPA’s responses were signed December 14, 2012). EPA’s action means that polluters in Wise County will have to do their fair share to reduce ozone levels in Dallas-Fort Worth, which have been among the worst in the country for many years. Because of the importance of this issue to the public health of Texans, EDF has already taken steps to defend EPA’s action in Federal court.

Background

Ozone pollution has long been regulated under the Clean Air Act because of the tremendous hazards that ozone poses to public health and the environment. High ozone levels lead to respiratory distress and disorders; decreased lung function; increases in emergency room visits and sick days; and more. To address the serious problem of ozone, the Clean Air Act provides a multi-step process for ensuring that all areas of the country achieve acceptable ozone levels. First, EPA must establish nationwide air quality standards for ozone (called National Ambient Air Quality Standards), which are required to be strong enough to protect public health with an adequate margin of safety. Second, EPA must designate which areas of the country meet those standards, and which do not. Lastly, states are required to submit plans for achieving and maintaining compliance with EPA’s ozone standards — with especially strict requirements for areas that currently do not meet the standards.

EPA last updated its ozone air quality standards in March 2008. The revised standard requires that average ozone concentrations over an 8-hour period remain at or below 75 parts per billion (ppb) — a level that is more protective than the previous standard set in 1997, but still significantly higher than the range of 60 to 70 ppb recommended by EPA’s own Scientific Advisory Committee. EDF has consistently advocated for a stronger ozone standard, and has even taken EPA to court over this issue together with other public health and environmental organizations. At the same time, EDF has also fought hard against attempts to weaken the 2008 ozone standards or stop their implementation.

Designation of Wise County

On May 21, 2012, EPA issued a regulation designating 45 areas of the country as out of compliance with the 2008 ozone standards – including a group of ten counties in the Dallas-Fort Worth area, which had long failed to meet the earlier and less stringent ozone standards. For the first time, however, the Dallas-Fort Worth designation also included Wise County, Texas, due in large part to emissions of nitrogen oxides and volatile organic compounds from a recent boom in oil and gas production in the area.

As EPA explained in a detailed technical analysis, Wise County was included in the Dallas-Fort Worth ozone designation because of the county’s contribution to unhealthy levels of ozone. Among other things, EPA found that ozone monitors less than half a mile from the county line were recording unhealthy levels of ozone; that Wise County emits some of the highest levels of ozone-forming pollution in the 19-county area surrounding Dallas-Fort Worth; and that the prevailing winds on high-ozone days are responsible for bringing that pollution from Wise County to the nearby city.

Ensuing Litigation and Requests for Reconsideration

EPA’s determination was reached after a lengthy process during which the state of Texas and other stakeholders had ample opportunity to submit comments and data on Wise County’s contribution to ozone in Dallas-Fort Worth. However, this didn’t stop the state, some local governments, and various oil and gas producers and trade associations from trying to stop the designation of Wise County by filing a total of 19 petitions asking EPA to reverse its decision. The state of Texas, Wise County, and four industry parties also filed legal challenges to EPA’s determination in the D.C. Circuit Court of Appeals — and EDF responded by moving to intervene in defense of EPA’s action.

EPA’s Denial of Reconsideration and Next Steps

In detailed responses to the petitions, EPA reaffirmed its analysis of Wise County’s contribution to the local ozone crisis and offered rebuttals to each of the major arguments advanced by the petitioners. EPA’s responses confirm that the designation of Wise County rests on the best available science. EPA’s action is also an important advance for public health — ensuring that polluters in Wise County will do their fair share to address ozone pollution in the Dallas-Fort Worth area, and that the important protections of the Clean Air Act extend to ozone-contributing areas and sources that have been overlooked in the past.

We hope that the parties challenging the Wise County designation will ultimately decide to demonstrate leadership by becoming part of the solution to the air quality challenges facing Dallas-Fort Worth. In the meantime, vital work remains to be done to defend EPA’s actions in court: the ongoing D.C. Circuit challenges to the original designation of Wise County, which were suspended while EPA processed the reconsideration petitions, are likely to resume in a matter of weeks. In addition, EPA’s decisions on the petitions may provide fresh fodder for additional legal challenges in the D.C. Circuit. EDF’s legal team stands ready to vigorously defend EPA’s decision in the months ahead.

NERC Demands Action From ERCOT To Keep The Lights On In Texas

This commentary was originally posted on EDF’s Texas Clean Air Matters blog.

Last week was a busy one in Texas, with the beginning of the 83rd Legislative session attention was focused on incoming lawmakers, both seasoned and freshmen, and the opportunity that only happens every two years to address serious issues in Texas including water scarcity, education, tax issues, and of course energy issues.

So it’s understandable that no one seems to have noticed a strongly worded letter to the Electric Reliability Council of Texas (ERCOT) from the North American Electric Reliability Corporation (NERC) last Monday demanding more action to ensure electric reliability in Texas, and asking ERCOT to report back to NERC by April 30 on additional actions taken. NERC isn’t some federal boogey man either; it’s a corporation founded by the electric industry to create commonly accepted standards for electric reliability across North America, usually through voluntary compliance. President Bush’s Energy Policy Act of 2005 gave the corporation “the authority to create and enforce compliance with Reliability Standards,” which is where this letter comes into play.

In their 2012 report, NERC highlighted ERCOT as the only region in North America that was not maintaining adequate electric reserves to meet demand, and with this letter they made it very clear that the actions taken to date have not done enough to mitigate that risk. In the letter, NERC President Gerry Cauley notes that the PUC and ERCOT are continuing to address energy reliability issues, but finds that “solutions have not yet sufficiently materialized to address NERC’s reserve margin concern.”

Cauley goes on to say that “it is still unclear to us how ERCOT intends to mitigate issues that may arise on the current trajectory and when new resources may be available to meet growing demand.” So according to the corporation whose membership consists mostly of utilities, grid operators, large and small customers, and electric regulators, the actions that the PUC and ERCOT have taken at this point are not enough to ensure we’ll have reliable electric supply, risking blackouts as soon as this summer.

As lawmakers settle into Austin for the next few months they’ll certainly be paying close attention to this issue, though many have indicated they would prefer that ERCOT and the PUC develop the solutions to this problem. Cauley’s letter serves as notice that the PUC and ERCOT need to be more aggressive if they want to ensure a reliable supply of power in Texas. Certainly both agencies are putting serious time and effort into keeping the lights on in Texas, including effort so expand existing demand response programs, but NERC clearly thinks they need to be doing more.

All of this reminds me of the Texas drought: a year ago it was a huge looming crises, but a break in the weather took everyone’s mind off of the drying rivers and lakes, even though they never really recovered. Lately the drought has been back in the news as Texans realize that we’re basically in the same place that we were in 2011.

No one could accuse ERCOT or the PUC of sitting idly by or pretending this risk isn’t real. However, they have yet to send a strong enough signal to the market to spur investors in demand response or any other resources to develop new projects. About the only thing that has been done is the extension of the federal production tax credit for wind energy, which has wind developers racing to build new projects in Texas. The concern is that the solutions they’ve begun work on to date may not get us to where we need to be by this summer.

This letter is a reminder that the energy crunch hasn’t gone away, things are not likely to change in the near term if serious action isn’t taken soon. That is a risk we can’t afford to take given a looming drought, a growing economy and a stagnant electric market. NERC has asked ERCOT to report to them on their progress by April 30, near the end of our biennial legislative session, and one in which the critical PUC/ERCOT sunset legislation is expected to pass, maybe legislators should consider a similar request.

Wind Update: The PTC And A Christmas Day Record

This commentary was originally posted on EDF’s Texas Clean Air Matters blog.

Source: Houston Chronicle

Good news came out of the fiscal cliff ordeal last week when Congress voted to extend the Production Tax Credit (PTC) for renewables, which had expired on January 1. While the 2.2 cent-per-kilowatt-hour credit has only been extended through 2013, it provides some certainty to an industry that was holding its breath. As we’ve discussed previously, while the tax breaks for the oil and gas industry are written into the permanent tax code, the credits for wind and other renewables are not. Created under the Energy Policy Act of 1992, the PTC income tax credit is allowed for the production of electricity from utility-scale wind turbines, geothermal, solar, hydropower, biomass and marine and hydrokinetic renewable energy plants.

While this extension through the year does not appear to provide a great deal of long-term certainty, my colleague Colin Meehan points out that “an important distinction with this extension is that prior to 2013, the tax credits were awarded to facilities operational by the end of 2012. The extension now applies to facilities for which construction begins by the end of 2013. As a result, this is more like a two-year extension.” Cameron Fredkin, director of project development at Cross Texas, further emphasizes the point by highlighting that “the key provision in the extension is the requirement to begin construction in 2013 versus previous one-year extensions that required wind developers to complete construction and begin operations in 2013. Wind developers in the Panhandle region in the interconnection study process would have had difficulty achieving commercial operations in 2013.”

According to the American Wind Energy Association, “America’s 75,000 workers in wind energy are celebrating over the continuation of policies expected to save up to 37,000 jobs and create far more over time, and to revive business at nearly 500 manufacturing facilities across the country. Half the American jobs in wind energy – 37,000 out of 75,000 – and hundreds of U.S. factories in the supply chain would have been at stake had the PTC been allowed to expire, according to a study by Navigant Consulting.”

As I wrote back in November, many of those projects and jobs that were on the line while Congress delayed are here in Texas. In Amarillo, Walt Hornaday, president of Ceilo Wind Energy, said the tax credit helped “dust off projects [they] had put on the shelf.” Hornaday says he is “impressed wind was in the bill with big-ticket items like Medicaid and the Farm Bill. It used to be wind wouldn’t have a chance to be included. I thought we’d be left out in the cold.” According to The Hill, “The wind industry has floated a phase-out plan for the credit as a way to cement some stability and avoid annual battles to extend the credit. Securing the extension now sets the table for those discussions.”

Andy Geissbuehler, head of Alstom’s North American wind business, a manufacturer of wind turbine equipment, believes that “the extension of the Production Tax Credit for wind power is a positive development for our company, our customers, and the many workers across the country employed directly and indirectly by the wind power industry. As an equipment supplier, we stand ready to provide the equipment that can be manufactured in our Amarillo facility to project developers across North America. We remain optimistic about the long-term market for wind power market in North America, especially now that the U.S. Production Tax Credit has been extended another year.”

One possible casualty of Congress’ stalling is the $5 million, 80,000-square-foot facility left behind by Zarges Aluminum Systems. The German company planned to produce wind tower components, such as ladders and platforms. A spokesman at the time blamed the recession and uncertainty regarding the tax credits as well as low natural gas prices for putting pressure on its customers and the company itself.

This extension comes at a time when wind set a new record in 2012 by installing 44 percent of all new electrical generating capacity in America, according to the Energy Information Administration, leading the electric sector compared with 30 percent for natural gas, and lesser amounts for coal and other sources. Here in Texas, wind set another record, providing 8,638 megawatts (MW) of power on Christmas Day, with 6,600 MW coming from West Texas wind farms and 1,600 MW coming from the Texas coast. This adds up to nearly 26 percent of the system load, which is 117 MW higher than the previous record set in November 2012.

As Kent Saathoff, vice president of grid operations and system planning at the Electric Reliability Grid of Texas (ERCOT), points out, “Unlike traditional power plants, wind power output can vary dramatically over the course of a single day, and even more so over time. With new tools and experience, our operators have learned how to harness every megawatt of power they can when the wind is blowing at high levels like this.

Those new tools and experience are exactly why the PTC is an important component of this emerging energy sector’s ability to grow and innovate, especially as ERCOT reviews an additional 20,000 MW of wind power capacity. This is in addition to the more than 10,000 MW it already has installed, which is the highest amount in the nation.

A Red Flag On Disclosure Of Hydraulic Fracturing Chemicals

It’s not often that a new regulatory idea becomes so popular that one or more states per month climb on the bandwagon. But that is precisely what has happened with the push to disclose which chemicals are pumped into the ground to stimulate oil and natural gas production during the process known as hydraulic fracturing, or “fracking.”

A year ago, only three states (Arkansas, Montana and Wyoming) required oil and gas producers to tell the public what chemicals they were using. Two other states (Colorado and Texas) were actively developing such rules. Today, just twelve months later, statutes or regulations mandating “frack” chemical disclosure are on the books in no fewer than 18 states, and proposals are pending or under consideration in several others.

FracFocus, an online registry that compiles information on hydraulic fracturing chemicals both for states where disclosure is voluntary and required, has been up and running for just 20 months, but already it houses approximately 800,000 records that include ingredients data. As of December 5, 2012, this data represented 33,606 wells. The amount of information on the site continues to grow rapidly.

It is impressive that so much information has been made available in such a short time. Still, people have begun to wonder whether the disclosure rules are accomplishing what was intended. The question is important because rules that aren’t working need to be changed. A good regulatory system is based on a process of continual improvement, not a naive idea that the rulebook can be written in a way that will never need changing.

Unfortunately, judging from early press reports, there are quite a few bugs in the system. To be fair, the reporting requirements are quite new and still being implemented — and analysis of the data has barely begun. But  problems are emerging. The issue receiving the most media attention is the sheer number of trade secret claims. Read More »

Pecan Street Inc. Researchers’ Report Receives Outstanding Paper Award

Source: Pecan Street Inc.

With 1.8 gigawatts (GW) of solar power installed in 2011 and an expected 2.8 GW in 2012, it is safe to say that solar energy has solidified its role as an important part of our nation’s energy portfolio. Affordability, competitive financing and reduced greenhouse gases are just a few of the reasons why the number of solar installations has skyrocketed in the past several years.

Now, new research from Dr. Alexis Kwasinski, Dr. Fabian Uriarte, and Amir Toliyat, engineers from the University of Texas at Austin, sheds some light on how rapidly growing solar installations can work with the current electric grid. For their groundbreaking findings in “Effects of high penetration levels of residential photovoltaic generation,” they were recently awarded an Outstanding Paper Award at the International Conference on Renewable Energy Research and Applications (ICRERA) in November for their in-depth research and innovative solutions.

Jump started by a $10.4 million grant from the Department of Energy, Pecan Street Inc. is a “community-wide collaboration to fully reinvent the energy delivery system”  based in Austin, Texas.  This living ‘smart grid laboratory’ provided a perfect data collection site for the researchers. Pecan Street’s leadership focuses on developing new technologies that reinvent the way we create and use energy, so that residents drive electric vehicles, invest in cutting-edge technology and, of course, use solar panels.

The massive amount of data gathered from Pecan Street’s efforts provided researchers the opportunity to analyze solar energy’s effect on the three key characteristics of “power quality” (voltage level, voltage unbalance and power factor).  The researchers found that energy inflections (voltage levels and voltage unbalance) did not create any major concerns with the power grid, despite unfounded claims to the contrary by some solar critics.

Digging further into the data, the researchers unexpectedly found that power factor could become a real issue if solar installers don’t use modern equipment that provides for power factor support.  While the issue could become very real at higher levels of solar penetration, the solution is simple, cheap and currently available; it simply means installers should begin using newer models of solar panel “inverters,” which convert solar power into electricity that can be fed into your grid and home.

Inverters simply convert raw DC power to AC power (i.e. the type of electricity we need to use everyday household items). Maximizing the amount of electricity that is converted into usable power makes solar energy more competitive, ensuring that it will remain an important and growing part of our nation’s energy mix.

It’s exciting to see that these researchers are receiving accolades for their groundbreaking work, and international acclaim is always an excellent motivator for this kind of work, but it’s nice to be appreciated where you hang your hat too.  Fortunately that doesn’t seem to be a problem, since earlier this year Austinites voted in the Best of Austin 2012 award by the Austin Chronicle for Best Way to Turn Some Green Even Greener.  Their choice: Pecan Street Inc.

On-Bill Repayment: A Way To Eliminate The Upfront Costs For Energy Efficiency Projects

When a state is facing electric resource shortages, like Texas is, it’s just common sense to explore all the ways to make our electric use more efficient. We know efficiency makes sense – in terms of grid reliability, lower emissions, and reduced costs to ratepayers. But there is a barrier to some ratepayers in implementing more energy efficiency: upfront costs. Several options currently exist to finance efficiency, such as home equity loans and incentive programs through utilities. But what about creating a market to allow private investors to invest in the market by offering lower rates for utility customers by ensuring some security through repayment on the utility bill? That’s what on-bill repayment aims to do.

On-bill repayment (OBR) offers an opportunity for home and building owners to finance energy efficiency and renewable electricity generation projects through cost-saving loans from third-party investors. The loans are repaid through customer’s utility bills.  The money comes from private sector lenders at no cost to ratepayers or taxpayers.  OBR also allows for longer term loans with lower interest rates.

The general concept of OBR is not new. Several utilities around the country have instituted on-bill finance programs. However, there is a key difference. On-bill finance programs use utility money to finance the program, thus creating an additional cost for the ratepayers. On-bill repayment would use new money from third parties, such as banks, to create a new market that is secure, cost effective, and enables more bang for the buck in terms of what the ratepayer receives.

OBR is a flexible program that works for a wide variety of properties and vendor business models.  In some programs, contractors are told what solutions can be offered to each customer.  OBR, on the other hand, allows each contractor or vendor significant latitude to design solutions that meet the needs for their customers.  This could include everything from insulation upgrades for residential customers or lighting upgrades for restaurants all the way to deep retrofits of commercial or industrial properties.  All of these would be delivered by the private sector and would be completely voluntary to each property owner.

Benefits of OBR include:

  • Job growth: We estimate that it could generate 100,000 new jobs to install energy efficiency and renewable electricity.
  • New market creation: We estimate that OBR could generate $13.5 billion over a decade in private sector investments in energy efficiency, renewable generation, and demand response projects.
  • Ratepayer and state savings: OBR would promote energy efficiency and distributed energy resources that avoid the cost of expensive new power plants and other high-cost generation—saving ratepayers $4.8 billion in energy bills.
  • Flexibility for contractors and vendors: Program participants would have considerable discretion to design product offerings and go-to-market strategies to meet their customers’ needs.

In a state like Texas that prides itself on making its economy attractive to investors and creating markets, especially in the energy sector, OBR could be an effective tool to opening up the state to a private sector solution that can ameliorate our Texas energy crunch. Efficiency is an investment that makes sense for Texas. As utilities face increasing demands on their energy resources, and fewer dollars to spend on efficiency for their customers, giving them another tool, energized by funds from the private market, will benefit the entire state.
