Wind Makes Up 26% Of ERCOT Load In November, New Record

Source: Environmental Law Institute

Despite having escaped this summer without rolling blackouts and the kind of heat we experienced last year, Texas is still dealing with the energy crunch issue. Luckily, our state is home to the nation’s largest wind power industry and it contains about a fifth of the country’s wind turbines.  The Electric Reliability Grid of Texas (ERCOT), the Texas grid operator, announced that earlier this month wind throughout the state contributed 26 percent of the load on the grid, setting a new record.  On November 10, a total of 8, 521 MW was produced, beating the previous July 19 record.  For the first eight months of this year, wind accounted for 8.7 percent of the grid’s energy.

This is in addition to wind helping Texas avoid blackouts in February of last year, when a cold front proved too much for many traditional power plants. On February 2, 2011, wind energy played a critical role in limiting the severity of the blackouts, providing enough electricity to keep the power on for about three million typical households. ERCOT confirmed that wind provided between 3,500 and 4,000 MW of electricity (about seven percent of ERCOT demand at that time), roughly what it was forecasted and scheduled to provide. Texas wind provided this electricity during the critical 5 to 7 a.m. window when the grid needed power the most.

As an E&E ClimateWire article points out, wind farms in west Texas contributed about 7,000 MW to the system on Nov. 10 when the record was hit. Coastal towers and turbines, which were key to avoiding power shortages last year, contributed about 1,100 MW of supply. Texas holds more than 10,000 MW of wind power capacity overall.

This is all welcomed news for an industry holding its breath as Congress debates the renewal of the expiring Production Tax Credit (PTC) for renewables, which provides a 2.2 cent per kilowatt-hour tax credit for the first ten years of electricity production from utility-scale turbines.

With Texas being a major manufacturer of wind equipment in addition to relying on it for power, many jobs hang in the balance.  According to a Sierra Club report,  “a typical new 250 megawatt wind farm will create 1,079 jobs – manufacturing jobs, construction jobs, engineering jobs and management jobs.” Another report by NRDC estimates that from a 250 MW project, “non-construction businesses would account for 557 jobs — 432 in manufacturing, 80 in planning and development, 18 in sales and distribution and 27 in operations and maintenance. Construction would check in with another 522 jobs, doing things like buildings roads and foundations, installing turbines and wiring and connecting the power plant to the grid.”

In Texas, the expiration of the PTC could not only mean stunting job growth but would also likely create layoffs. According to Walt Hornaday, president of Cielo Wind Power, an Austin-based wind farm developer, “We haven’t had the industry come to a stop like this before in a long, long time.” His company is pursuing work in other countries, but otherwise, he said, “we would definitely be looking at very large layoffs.”  Even Governors Perry’s own report cites a Mitchell Foundation analysis that the expanding wind and solar energy industries are projected to add 6,000 jobs in Texas per year through 2020 and, as of last year, over 1,300 Texas companies employ nearly 100,000 workers in industries directly and indirectly related to renewable energy.

And for those that now claim energy subsidies must end, despite being proponents for fossil fuel dollars, let us not forget what it has taken and continues to take to support the fossil fuel industry. First, the largest subsidies to fossil fuels were written into the U.S. Tax Code as permanent provisions.  Furthermore, the largest break, the Foreign Tax Credit, provides around $2.2 billion annually and applies to the overseas production of oil through an obscure provision of the Tax Code, which allows energy companies to claim a tax credit for payments that would normally receive less-beneficial tax treatment. In an analysis conducted from 2002 to 2008, by the Environmental Law Institute, fossil fuel subsidies accounted for $72 billion over that span of seven years. On the renewable side, over half of the $29 billion subsidy amount supports corn ethanol. For traditional renewables like wind and solar, the total amount received was $12.2 billion, amounting to $1.74 billion annually.

Given Texas’ resource adequacy problems, it makes no sense to divest from a clean resource that provides up to 26 percent of our power while growing the economy.

As we mentioned in August, please contact your elected officials and ask them to renew the PTC before the end of the year. It’s good for Texas, the nation, and the environment.

Texas Electricity Generation Plan Focuses On Fossil Fuels Instead of Diverse Infrastructure That Includes Renewables & Efficiency

Last week, the Public Utilities Commission of Texas (PUC) voted to approve a staged increase of wholesale offer price caps in the Texas electric market for the Electric Reliability Commission of Texas (ERCOT) in order to prop up lackluster investment interest in new power plants. This change fits well with established theories of competitive markets, but it does little to resolve current issues beyond sending a signal to investors that the PUC intends to act further to incentivize investment in new generation.

That same day, the commissioners “swatted aside” a petition to revisit the state’s goal for non-wind renewable energy without allowing any public discussion.  Given our need for new drought-proof energy and the fact that solar costs have fallen 80 percent in the last three years, this seems like an issue the PUC would be eager to take up.  In fact, when PUC Chairman Donna Nelson was pressed during a state senate hearing this spring to identify state policies that had successfully added electric drought-proof resources, she focused on both the state’s Renewable Portfolio Standard (RPS) and energy efficiency goals.

The PUC has now voted twice to raise wholesale offer price caps for electric generation, even though it voted recently to make it more difficult for the state’s energy efficiency programs to succeed by lowering their price caps.  Last week, while voting to increase price caps again, Chairman Nelson noted that the work to ensure new electric generation did not end with that vote.   I hope that’s the case because I want to make sure we can keep the lights (and air conditioning!) on too.  Since the PUC denied the petition to create a rulemaking to expand the RPS, it seems that their work on expanding electric generation is limited to non-renewable, fossil fuel power plants and not much else.  This is unfortunate given the fact that renewable energy is expected to be the world’s second largest source of power by 2015, according to the recently released World Energy Outlook.

Over the last century, Texas has dominated the international energy scene. However, as the playing field changes, we need to make sure that Texas doesn’t fall behind as a state and an international energy leader.  Recent PUC decisions may increase that risk, but their final decisions on a new market structure will likely be the ultimate decider.

Texas and its citizens deserve a competitive and diverse energy infrastructure that allows for a wide variety of characteristics in energy resources such as storage, customer-side energy resources, renewable energy, and cleaner-burning modern natural gas-fired power plants. Anything less will risk not only our state’s near term electric grid reliability, but also our long-term economic viability as well.

Smart Technologies Allow For Improved Resiliency During Catastrophic Texas Weather

As we continue to reflect on Superstorm Sandy and its devastating aftermath, it is encouraging to point out how smart technologies can aid in lessening the impacts. While a smart grid will not prevent massive natural disasters from wreaking havoc on communities causing power outages and destruction, it can help lessen the consequences and quicken recovery.

My colleague Miriam Horn wrote a piece earlier this week and said, “We’re already seeing proof these [smart grid] investments can reduce recovery time, keep crews and customers safer, and save lots of money. Thanks in part to federal stimulus grants, a number of utilities are embedding sensors, communications and controls across their networks. On the power lines that it has helped prevent cascading disasters like the one that knocked out power to 55 million people in 2003, when a single Ohio tree fell on a power line. Automated systems can detect a fault, cordon it off and reroute power flow around it.”

Furthermore she states that “digital smart meters, capable of two-way communications, have also proved their worth: providing utilities real-time, granular visibility into their networks, without resorting to (often failing) phones or trucks dispatched on wild goose chases.  Programmed to send a “last gasp” signal when they lose power, those meters have enabled rapid diagnostics – pinpointing exactly which homes or blocks were out, where the break had occurred – and expedited repairs.”

In the DC area, “when the storm struck Monday, Pepco, the utility serving the nation’s capital and its Maryland suburbs, began getting wireless signals from smart meters on its network registering where individual customers had lost power, said Marcus Beal, senior project manager for Pepco’s smart meter program. One of the first movers to install smart meters, Pepco has 725,000 in place and had activated 425,000 of them before the storm struck. Instead of relying solely on customers to call in outage information on specific neighborhoods, Pepco dispatchers can track damage based on smart meter signals that are automatically linked into the utility’s outage map, guiding priorities for deploying repair crews, Beal said. As repairs proceed, the utility is also able to “ping” meters remotely to verify where and when power has been restored. ‘They certainly improve recovery time,’ Beal said, ‘without a doubt. They help to improve the efficiency of the restoration.’”

Here in Texas, we are prone to two main types of extreme weather conditions: hurricanes on the coast and tornados on the plains. Over the past few years we have witnessed the increased intensity of both in Texas and across the US. In 2008, When Hurricane Ike struck Houston as a Category 4, nearly 99 percent of residents lost power, which is about 2 million people.  After 13 days one-quarter of the residents of the fourth-largest U.S. city still did not have electricity.

In 2010, CenterPoint Energy, the utility in the area, began rolling out smart grid updates and said that future hurricane-related electric power outages should be shorter because of smart meters and other grid improvements. In comments filed by the City of Houston to the Public Utility Commission (PUC), a Task Force Report assembled after Ike identified the installation of intelligent grid technology as the ‘best return-on-investment to improve grid resilience and enable storm recovery system-wide’.  Therefore, the Task Force recommended the acceleration of CenterPoint’s intelligent grid deployment in the Houston area. A more intelligent electric grid, combined with smart meter technology, improves reliability by enabling automated self-healing of the grid, which results in fewer outages and faster restoration times for customers. This is crucial for public safety along the Texas Gulf Coast, and in the Houston area, specifically.

For other non-coastal areas in “Tornado Alley” Texas, cyclones can be truly terrifying and unpredictable, like the tornadoes that swept through the Dallas area in April of this year.  While images of tractor trailers and school buses being lifted and thrown like toys are scary, Texans can at least be encouraged by the example of Alabama Power, “which was slammed in April 2011 by 30 tornadoes across 70 miles with winds up to 190 mph. The twisters left 400,000 without power and thousands of poles, wires and substations damaged or destroyed. But by using its 1.4m smart meters to locate the outages and prioritize repairs, the utility restored all of its customers within a week. It also drives 4 million fewer miles each year.”

Across the country, smart meters and grid technologies are being installed, providing more reliability and efficiency in the event of disasters and during normal operations. The Federal Energy Regulatory Commission estimates the percentage of meters in the United States using the new digital technologies increased from 6.5 percent in 2009 to between 13 and 18 percent last year. The IHS consulting firm projects that, by the end of this year, one-third of all meters in North America will be advanced smart versions with two-way communications capability.

Luckily, Texas has 1 million smart meters already installed and is well on its way to 7 million by 2013.

With novel ways of planning, new technologies and innovative infrastructure – from the potential of microgrids enabling community self-sustainability by disconnecting from damaged main grids, and distributed renewable generation letting consumers power back up, to electric vehicles allowing people to avoid the long gas lines and shortages – the future can allow us to be more resilient in the face of catastrophe.

Loose Use Of Facts Undermines Credibility Of White’s OpEd

This commentary was originally posted on the EDF Texas Clean Air Matters Blog.

An erroneous and misleading opinion piece by Kathleen Hartnett White with the Texas Public Policy Foundation, ran in Sunday’s The Austin American-Statesman. In the article, White misrepresents several important details from a 4-year old EDF report that was prepared by Dr. Al Armendariz, a former Regional Administrator of the Environmental Protection Agency. The report catalogued emissions from oil and gas production in the Barnett Shale area. Her purported facts about the study findings are just plain wrong.

First, she claims that the report concluded that ozone precursor emissions from Barnett Shale production are twice as large as all mobile source emissions in the area. In fact, the report concluded that peak Barnett Shale emissions, while significant, were roughly comparable to emissions from cars and trucks (see press release accompanying the report).

White then claims that Dr. Armendariz’s study considered methane to be an ozone precursor, contrary to what is clearly stated in the report at p. 8. While it is true that methane does form ozone, albeit slowly, the report states “[m]ethane and ethane are specifically excluded from the definition of VOC” (volatile organic compounds). Thus, the report excluded methane from the comparison to mobile emissions of ozone precursors.

It is unclear if the author even read Dr. Armendariz’s work, which was not computer modeling, as she claims. Rather, it was an emissions “inventory,” a catalog of the air pollutant emissions from oil/gas sources in the Barnett Shale area, constructed using established engineering practices and industry-backed data sources. The core pieces of information for the inventory were oil/gas production data that are available for every county in Texas from databases at the Texas Railroad Commission. Dr. Armendariz’s resulting emissions estimates were in reasonable agreement with estimates issued by the Texas Commission on Environmental Quality later in 2009 (10-20% difference).

You can’t make a strong case when you get facts wrong. And, it is irresponsible for White to make her case by manipulating science, while cynically blaming government bodies of committing the same sin.

It’s time we all get the facts right and use science to expose truths, not veil our own agenda. For our part, EDF is working with leading academic researchers and industry leaders to conduct scientifically rigorous measurements of emissions from natural gas production. Leaks that occur during production (as well as distribution and use) stand to significantly undermine the potential of natural gas as a lower carbon energy source.

EDF Energy Innovation Series Feature #12: Community-Owned Utility – CPS Energy

Throughout 2012, EDF’s Energy Innovation Series will highlight around 20 innovations across a broad range of energy categories, including smart grid and renewable energy technologies, energy efficiency financing, and progressive utilities, to name a few. This series will demonstrate that cost-effective, clean energy solutions are available now and imperative to lowering our dependence on fossil fuels.

Find more information on this featured innovation here.

Want to build CPS Energy’s new massive solar project in San Antonio?  Pack your bags.  You may have to move to the Alamo city and hire a few hundred local employees.

With more than $2.3 billion in annual revenue and $10 billion in total assets, CPS Energy (CPS) is the largest municipally-owned electric and gas utility in the country, providing service to almost 750,000 customers in and around San Antonio, Texas.

CPS’s strategic goals and decisions are among the most progressive in the country.  It is shooting for 20 percent renewable energy generation capacity by 2020 and has plans to mothball one of its 1970s-era coal plants in 2018, 15 years earlier than expected. But beyond carbon reduction targets and renewable energy commitments, CPS is using a very old-fashioned tool to spur energy innovation deep in the heart of Texas.

The tool? LEVERAGE. With a $2 billion annual operating budget and the highest credit rating in the industry, CPS has dollars to spend on innovative technologies, and the company is leveraging its renewable energy and clean technology dollars to bolster local job growth, protect the environment and help its customers use energy more wisely. CPS calls it the “New Energy Economy.”

“We have the opportunity to leverage our buying power to benefit our community, by requiring our partners to add more value to San Antonio,” said Doyle Beneby, President & CEO of CPS Energy. “That value comes in the form of jobs for our community by establishing headquarters and adding manufacturing. It also comes in the form of investment in San Antonio’s educational institutions.” Read More »

Chasing Red Herring On The Wind

The saying goes that hunters used smoked red herrings to train their dogs, trying to throw them off the scent of the hunt with something that has a much stronger and tempting smell but ultimately wasn’t the real target.  This is quite similar to recent discussions about resource adequacy – now that it’s become clear that the EPA isn’t the reason for power plants shutting down, some seem more focused on finding another scapegoat rather than addressing the real problems in the market.

There was a time, not too long ago, when the low marginal costs of technologies like wind and solar power were seen as a good thing.  In 2009 the Public Utility Commission (PUC) said “renewable generation has reduced wholesale and retail energy prices during some periods and has been instrumental in moderating price increases during periods in which the cost of natural gas was increasing.”  Back then, this was seen as a good thing because there was a need for a moderating influence on high natural gas prices at the time.

Times have changed though, and lately PUC commissioners have taken to blaming wind energy for their current troubles, even when their own paid experts tell them otherwise.  In a Senate Natural Resources hearing last week, PUC Chairman Nelson stated that “the market distortions caused by renewable energy incentives are one of the primary causes, I believe, of our current resource adequacy issues.”

The problem with this claim is that it isn’t supported by the facts, and most industry experts agree that the real problem (if you want to call low energy prices a problem) is a combination of a market structure in need of reform and consistently low natural gas prices.  In the Brattle Group’s report on resource adequacy issues in ERCOT they make a pretty strong case that gas, not wind, is responsible for setting the bulk of market prices.  Perhaps the best way to look at it is this chart showing how electric rates lined up with gas prices over the last decade.
