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.

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.

Pecan Street To Be Recognized At GridWeek 2012

Next week, thousands will descend on Washington DC for GridWeek, the “only international conference focused on smart grid.” Now in its 6th year, GridWeek “attracts the complete diversity of global electric-industry stakeholders to explore Smart Grid’s impact on the economy, utility infrastructure, consumers and the environment.”

The theme for this year is centered on deriving value for all stakeholders from an increased complexity, as “grid-modernization and smart grid efforts provide the energy industry with more information, a broader system view, and more efficiency and control.” Three key elements will be explored: stakeholder value, managing complexity and smart energy policy. EDF Economist Jamie Fine will be speaking on the “New Revenue Streams for Utilities” and “Smart Grid’s Role in New Air Quality Requirements” panel discussions at GridWeek.

At the center of all of these themes is Austin’s own Pecan Street Inc. (Pecan Street). Which is why it is no surprise that it is being recognized by the GridWeek Advisory Board for “significant achievements in “Extracting Smart Grid Value” — for all stakeholders, including utilities, consumers and society at large.” Also recognized are the Smart Grid Interoperability Panel (SGIP) and Green Button, a “voluntary effort and the result of a White House call to action: ‘provide electricity customers with easy access to their energy usage data in a consumer-friendly and computer-friendly format via a “Green Button” on electric utilities’ website.’”  Read More »

Shut Down The Texas Government (Power)!

Source: Jon Rogers

These days it seems “shutting down” the government is a popular rallying cry in Texas. So, why not do it…er…or at least shut down the electricity when it’s not being used!?

As many of us enjoy the shortened work week due to the Labor Day holiday on Monday, I thought it would be a good time to look into what kind of demand response (DR) government buildings can participate in during holiday and seasonal closings.

We have discussed the benefits of both residential and commercial DR and governments can represent large or small entities depending on their size. The Texas Facilities Commission (TFC), responsible for “planning, providing and managing facilities for more than one hundred state agencies in over 290 cities throughout Texas,” has a current inventory totaling “24 million square feet of leased and state-owned properties.” Of that, offices make up about 6 million square feet across eight different cities.

These state agencies annually “consume over $200 million in electricity, which is procured and billed on thousands of separate accounts through various providers. In an effort to reduce these expenditures, the Office of Energy Management (OEM) is looking at ways to aggregate the State’s electrical load into fewer accounts, perhaps into just one. This strategic initiative could take advantage of negotiation opportunities, economies of scale, consolidation of facility loads and load scheduling resulting in the TFC saving thousands of dollars a year on electricity alone.”

Furthermore, the “OEM is taking a more expansive look at its resources, including purchasing, producing and distributing, and actual consumption. For example, it recently proposed aggregating the States electrical load to benefit from economies of scale, wholesale rates, reduced peak demand charges, and to acquire a more sophisticated rate structure and is currently studying the possibility of incorporating combined heat and power in its production.”

The TFC is also working with the General Land Office (GLO) to aggregate smaller state agency accounts to provide volume discounts for these accounts. Currently, smaller state agencies procure gas supplies from the local gas companies or in amounts from the GLO that do not render the economies of scale capable with the aggregate consumption with the TFC. By aggregating these smaller amounts, the TFC gets a better deal for the buildings under the TFC’s control and the other agencies. Read More »

In January, we discussed the benefits of demand response (DR) and how Texas is not taking full advantage of it. Not only is DR a low cost, zero water source for providing capacity through conservation, but it can also actually directly benefit consumers financially. Furthermore, since residential and small customers account for “more than 70 percent of peak load” it is paramount that we tap into this resource.

The 13 Percent Reserve Margin

Fast forward to this summer, where a few factors have encouraged the situation as Texas’ energy crunch comes to light. In May, the 13.75 percent reserve margin became the center of discussion about how to proceed. Set in 2010 by the Electric Reliability Council of Texas (ERCOT) board, the 13.75 percent target planning reserve margin is to ensure enough power is available for contingencies such as extreme weather and unplanned power plant outages. However, a newly revised Capacity, Demand and Reserves (CDR) report shows that in 2014 we may be only at 9.8 percent and by 2015 this could drop to 6.9 percent, numbers that are very far away from the original goal.  A failure to meet this reserve creates instability, not only for the ERCOT market as a whole, but that uncertainty ripples through the state for all businesses and households.

In June, the peak energy forecast for this summer was surpassed. ERCOT had predicted a 66,195 megawatt (MW) peak demand for the whole summer, but we surpassed that with 66,583 MW in June, well before the string of 100+ degree days we have seen recently. 

The 15 Percent Potential From Demand Response

In June the Brattle Report came out reiterating FERC’s studies, which demonstrated that the potential for achievable participation in DR is 15 percent of capacity in Texas.  This means that “dynamic pricing and load control technologies are deployed on an opt-out basis, with roughly 75 percent of customers participating.”

So if Texas met this DR goal of 15 percent it would be enough to cover our reserve margin of 13.75 percent and then some. Without new power plants. Without any new generation capacity at all. While in actuality we would rely on other demand side resources as well – such as distributed generation and storage – it is very important to point out the link between the 13/15 ratio, and how much potential demand response provides us.

Even better is that unlike other mechanisms that do not benefit consumers financially such as the price cap increase, DR and other demand side resources can provide large gains for consumers. Not only do they encourage reductions in energy consumption and thus energy bills, but because there is an added value in providing that “negawatt” capacity back into the system, customers are compensated. As we noted in an earlier blog, in the PJM market, $20 million of the payments went to residential customers!”

While there are still only a few of these initiatives around the country, the momentum is alive. Last year, FERC Rule 745 was established that “requires wholesale energy market operators to pay DR participants the market price for energy when those resources are able to balance supply and demand as an alternative to additional generation, and when DR dispatch is cost-effective.” This lays the foundation for how consumers will be compensated. FERC Chairman Jon Wellinghoff put it well, “[this] final rule is about bringing benefits to consumers. The approach to compensating demand response resources as we require here will help to provide more resource options for efficient and reliable system operation, encourage new entry and innovation in energy markets, and spur the deployment of new technologies. All of this contributes to just and reasonable rates.”

On June 26, ERCOT moved in the right direction by approving a DR pilot project that “will allow eligible participants a half hour to respond to ERCOT requests to reduce their electric use. The program is open to electric users — either as individual customers or as part of an aggregated group of consumers — who can reduce demand on the ERCOT grid by at least 100 kilowatts, which is the amount 20 homes use during peak demand.”

This follows a rule change adopted by the PUC in May that “authorizes ERCOT to conduct pilot projects to ‘evaluate resources, technologies, services, and processes that demonstrate the potential to advance the operational and market functions of the ERCOT system.’ This is the first pilot project approved under the new rule.” EDF commented on these rule changes and we are pleased to see ERCOT moving forward with these pilots. While many more deployments need to begin, we are headed down the right path and finally waking up the innovations needed in the energy market.

PUC Resource Adequacy Workshop on Friday, July 27

Source: Brattle Group. “ERCOT Investment Incentives and Resource Adequacy.” June 1, 2012

This Friday, the Public Utility Commission (PUC) will host a workshop to discuss the Brattle Group’s recommendations for Texas’ resource adequacy predicament and how to move towards sustained reliability. This workshop is timely, since the Texas energy crunch continues to be in the spotlight. Just last week, the New York Times reported that Texas ranks last in electrical reliability among all states in the U.S. Texas won’t stay open for business if that remains the case and year after year it seems our state energy policy is based on a hope and a prayer

Table 1 of the Brattle report outlines the five policy options to solve the long-term problems.

The report specifically states that “reliance on scarcity prices is unlikely to achieve current reliability objectives.” Therefore raising the price cap is, alone, not going to solve the problem. As mentioned at the Senate Business & Commerce committee earlier this month, this issue was plagued by accusations that the market was being manipulated because of violent price fluctuations on June 25 and 26. It turns out the market is not being manipulated, which is good, but that it is really just dysfunctional in design, which is not so good. Colin Meehan’s blog last week highlights this issue and makes the point that while the PUC is willing to potentially pass the costs of a price cap increase onto ratepayers, it should also consider demand-side resources suggested by Brattle which could positively affect ratepayers. For example, in the PJM market demand-side resources are allowed to participate in energy and capacity markets and over $20 million of the payments went to residential customers.

EDF submitted comments for this workshop and will be in attendance. Other public comments were made from a variety of stakeholder’s including demand response advocacy groups, cities, MOUs, and power companies.

EDF believes that “such reforms must include a substantially increased role for demand response (DR) and other demand-side resources in ERCOT’s markets; the report provides ample supporting evidence for this need. EDF requests detail on the level of DR needed to maintain reliability in each scenario [in chart above], what would be required in each scenario to attain those levels, as well as the role of other demand-side resources in meeting future resource needs.”
