Don’t Turn The Lights Off On Demand Response

Source- FERC: National Assessment of Demand Response Potential

If Texas Legislators want to make sure the lights stay on this summer, they have a great opportunity to do so tomorrow, April 9, 2013, while saving electric customers money.  There are two critical bills being considered at the legislature in Texas that would expand the use of demand response, a tool that allows customers to voluntarily reduce peak, or high, electricity use and receive a payment for doing so in response to a signal from their energy provider.  We need to take advantage of tools like demand response to alleviate the pressures facing the Texas electric grid, what EDF refers to as the ‘Texas Energy Crunch,’ which include a shrinking water supply, growing population and rising summer temperatures.

Demand response has been identified by numerous experts as a key component to a reliable electric grid in Texas, and Tuesday’s Senate Business & Commerce Committee hearing at 8 am represents a great opportunity for the legislature to help meet future energy needs while providing direct benefits to customers and reducing water usage.

Demand response is critical to keeping the Texas electric grid humming.  According to a comprehensive report on the Electric Reliability Council of Texas (ERCOT) reliability from the Brattle Group, “the energy-only market will not dependably support ERCOT’s current reliability target until sufficient demand response penetration is achieved.”  Demand response can be deployed in a matter of months, while it usually takes two to five years to build a natural gas power plant, even after all the permitting and financing is completed.  At the same time, demand response provides financial incentives; in the mid-Atlantic region, where demand response plays a critical role in the electric market, customers were paid a total of $330 million last year.  At the same time, according to the grid operator for the region, PJM, demand response actually lowers overall energy system costs by bringing more competitive resources into the market.  During the summer of 2012, PJM estimates this effect saved all customers around $650 million.

The Texas Energy Crunch Report: Looking Back And Looking Forward

We have been blogging about the ‘Texas Energy Crunch’ for over a year now, and the issue has attracted attention from the media, the Texas Legislature and even international groups.  During all of that time, the Texas Public Utilities Commission (PUC), Electric Reliability Council of Texas (ERCOT) and stakeholders have continued to try to develop new markets and programs that will help ensure the state of Texas can keep the lights on this summer and into the future.  This seems like as good a time as any to step back and take stock of how far we have come and how far we have left to go.  To that end, EDF released this report: “The State of the Energy Crunch in Texas.”

The Energy Crunch is not a fleeting issue that will go away in the near future. It’s critical that we take action now to preserve our electric grid, the engine of the Texas economy, over the long-term as we face a shrinking water supply, a growing population and rising summer temperatures.  The ongoing drought puts Texas’ power plants at risk, threatening a return of the rolling blackouts caused by extreme winter conditions we experienced in 2011. State Climatologist and Governor Rick Perry appointee, John Nielsen-Gammon states, “Statistically, we are more likely to see a third year of drought.”  In recent testimony, Nielsen-Gammon reaffirmed that if the drought continued through this year, this drought is likely to be the second worst episode of drought in Texas’ history.

The solutions are out there in the form of customer, or demand-side resources, like energy saving demand response (DR) initiatives (which allow customers to voluntarily reduce peak electricity use and received a payment for doing so in response to a signal from their utilities), energy efficiency programs and increasing renewable energy sources like solar and wind power, all of which consume almost no water and can be built faster than gas and coal plants. This report provides an overview of these issues and concludes with legislative recommendations that will help meet future energy needs while providing direct benefits to customers and reducing water usage.

As economic growth continues to surge in Texas, state leadership must ensure a stable and secure supply of electrical power to businesses large and small, homeowners, hospitals and schools, among others. This challenge is critical in the face of a worsening drought, population growth and the failure by the PUC to take meaningful action after almost two years of deliberation. In the final months of the 83rd Legislative Session, lawmakers have an opportunity to directly address the Energy Crunch through several pieces of legislation that would help reduce customer energy bills, lower water consumption and increase business opportunities in Texas, while also reducing peak electric demand throughout the state.

Several of these opportunities have been identified by the PUC, but a lack of clear direction from Commissioners has left businesses hesitant to engage directly in the Texas market without a good understanding of the long-term outlook.  By providing the PUC with strong guidance on issues like demand response, innovative clean energy financing mechanisms and fair payment for locally generated electricity, the Legislature can help reduce the threat of extremely costly rolling blackouts across the state.

We cannot solve this problem with the same thinking that got us here. Technology has changed our lives and the energy industry over the past few years alone, creating new opportunities for innovation. Now the state needs to be smarter about the way energy is used, and it starts with using technology to better manage our electric grid. This includes taking advantage of market-based solutions such as demand response (DR), energy efficiency programs and the continued growth of renewable energy into a smart grid.

In our report, EDF details legislation that is currently being considered by several Texas House and Senate Committees to help meet future energy needs while providing direct benefits to customers and reducing water usage.  The list includes bills that allow all customer classes to participate in electric markets, provide innovative clean energy financing mechanisms and offer fair compensation for customers who provide power back to the electric grid by generating excess electricity from renewables or conserving energy using demand response initiatives.  The Energy Crunch hasn’t ended by a long shot.  Forecasts continue to show that we won’t have the level of reserves needed this summer to ensure reliability –particularly if the summer looks anything like 2011.  Similarly, EDF will continue to engage in the issue both on our Texas Energy Crunch website and through the discussions going on at ERCOT, the PUC and the Texas Legislature.

Stayed tuned as we continue to develop innovative, market-based environmental and economic approaches that seek to keep the lights on and benefit customers.

New Thinking Is Critical To Better Manage Water And Electricity Resources In Texas

Central Texas Workshop Discusses Opportunities For Resiliency During Extreme Weather Events

This commentary was originally posted on our Texas Clean Air Matters blog.

Last week, I attended a regional workshop that focused on adapting to extreme events, sponsored by the U.S. Environmental Protection Agency (EPA), the National Oceanic and Atmospheric Administration, the Water Environment Research Foundation, the Water Research Foundation, Concurrent Technologies Corporation, and Nobilis. This workshop was the sixth in a series organized around the country to determine what is needed to increase the resilience of water utilities and communities in the face of extreme weather events. While the focus was on water, time and again, electricity was brought into the conversation—the two are closely linked, and in Texas, a state facing shortages of both water and power, this will require some creative thinking on our part.

This workshop focused on Central Texas, in particular our drought. But as the two-day workshop went on, it became clear to the organizers when local water utilities and other stakeholders spoke, that drought was only one extreme event that Texas has had to deal with…and continues to deal with. We are a state of extremes—weather, politics, personalities—and we not only have drought to handle, but also hurricanes, floods, tornadoes, wildfires, and just generally scorching heat. One of the first speakers was John Nielson-Gammon, the State Climatologist based out of Texas A&M University. He confirmed that while these natural phenomena are not new to Texas, we are experiencing more intense weather events. Last year was one of the hottest in Texas since we started recording temperatures, and we are heading into the third year of a pretty gruesome drought. Not being prepared for extreme events to get worse seems pretty foolhardy.

During the workshop, we heard from a variety of speakers from around the Central Texas region, including from the Barton Springs/Edwards Aquifer Conservation District, the Lower Colorado River Authority, rice growers, the University of Texas, the high tech industry, and individuals from Austin, San Antonio, and Bastrop. These people are dealing first hand with the impacts of the extreme events we’ve had in the past few years. They are simultaneously trying to manage the current situation while planning for what the changing climate means in the coming years. It’s a difficult balancing act.

ALEC Updates & Action Alert: State-By-State Renewable Energy Attacks Are Underway

Back in November, I wrote about how the American Legislative Exchange Council (ALEC) was partnering up with the Heartland Institute to attack renewable energy standards across 29 states. As an organization propped up by the fossil fuel industry, this behavior comes as no surprise. But the sneaky way they are trying to undo laws that encourage solar, wind and other renewable energy sources needs to be exposed and citizens of these states must stand up to the corporate interests desperately holding onto their power to pollute.  Across the country, we are watching ALEC and industry allies try to unravel decades of progressive energy legislation.

In the sunny southwest, the Arizona Corporation Commission (ACC) has eliminated the performance-based incentives (PBIs) provided to commercial solar energy customers by the state’s two investor-owned utilities (IOUs). It also drastically reduced the upfront incentives (UFIs) provided by the IOUs to residential solar energy customers. SolarCity Governmental Affairs Director Meghan Nutting explained that “as the Arizona incentives have been slowly reduced, the industry has kept up. Ratepayers have invested in the industry to a point where we are almost without a need for incentives. But a sudden and complete elimination of all incentives that cuts the commercial solar industry off at the knees means we will have to start over.” The ACC decision, she added, means “people are going to lose their jobs in the sunniest state in the country in an industry that Arizona has depended on through the recession and should dominate.” The ACC commissioners’ rationale for the cuts was that they will reduce the Renewable Energy Standard and Tariff (REST) premium added to Arizona ratepayers’ utility bills to fund solar. The REST premium was established by the ACC in 2007 and is capped at $4.00 per month. Calculations by Arizona solar advocates concluded that the PBI cuts will save APS ratepayers no more than $0.02 to $0.06 per month.

When We Save Energy In Texas, We Also Save Water

Last week, the Texas Coalition for Water, Energy and Economic Security (TCWEES), of which EDF is a member, held a legislative briefing at the Texas Capitol titled Energy & Water, Dollars & Sense: Improving security and maximizing benefits to Texas businesses and residents. The briefing focused on the nexus of water and energy, and furthered the idea that where you save energy, you save water too. The briefing included a panel discussion and a question and answer session.

State Representative Lyle Larson from San Antonio welcomed attendees, a speaker that is well-suited to talk about water issues. Before becoming a state legislator, he served on San Antonio’s City Council, a city with one of the best water conservation programs in the country. Representative Larson started with an interesting point: In addition to the physical issues of water scarcity, we also need to resolve the psychological issues of water resources.

People simply do not think of water as a scarce resource, despite the multi-year droughts we’ve seen in Texas. Addressing water scarcity has been done in much the same way as system-wide power shortages: in a short term, reactive way, rather than a long term, proactive way. And we will never be able to meet our energy or water needs of our growing populations by being short-sighted.

Representative Larson said that water is the number one impediment to business no matter where you are in the world. Water-rich countries will take American jobs if we can’t address our scarcity, and water-rich states will take Texan jobs. We don’t deploy best management practices in this state when it comes to water. And calling for more water infrastructure is great, but conservation is going to save significantly more water than new infrastructure will. Read More »

New ERCOT Report Shows That Texas Wind And Solar Are Highly Competitive With Natural Gas

An interesting fact seemed to go unnoticed in all the press around the Electric Reliability Council of Texas’s (ERCOT) Long Term System Assessment, a biennial report submitted to the Texas Legislature on “the need for increased transmission and generation capacity throughout the state of Texas.” ERCOT found that if you use updated wind and solar power characteristics like cost and actual output to reflect real world conditions, rather than the previously used 2006 assumed characteristics, wind and solar are more competitive than natural gas over the next 20 years.  This might seem a bit strange since we’ve been told for years by renewable energy skeptics that wind and solar power can’t compete with low natural gas prices. Let me back up a second and explain what’s going on here, and what it means for both the energy crunch and Texas’ ongoing drought.

Every two years since 2005, ERCOT has used a series of complex energy system models to model and estimate future conditions on the Texas electric grid.  This serves a critical function for legislators, utilities and regulators and others who need to prepare for changes as our electric use continues to expand and evolve.  As with any model of this kind, the assumptions are critical: everything from the price of natural gas, to the cost to build power plants and transmission lines. Facing an acute energy crunch and given that solar and wind costs have come down a great deal since the first study in 2006, ERCOT dug a little deeper into their historical assumptions and developed a version of the model that used current, real-world cost and performance data for wind and solar power.

What they found was astounding: without these real-world data points, ERCOT found that 20,000 MW of natural gas will be built over the next 20 years, along with a little bit of demand response and nothing else.  Once they updated their assumptions to reflect a real-world scenario (which they call “BAU with Updated Wind Shapes”) ERCOT found that about 17,000 MWs of wind units, along with 10,000 MW of solar power, will be built in future years.

In addition to demonstrating the economic viability of renewable energy, these results show two drastically different futures: one in which we rely overwhelmingly on natural gas for our electricity, and one in which we have a diverse portfolio of comparable amounts of renewable energy (which does not use water) and natural gas.  All of this is crucial to keep in mind as the Legislature, the Public Utility Commission and ERCOT evaluate proposals to address resource adequacy concerns and the impacts of a continuing drought on our state’s energy supply.

Finally, one ERCOT statement in particular stands out from this analysis, in direct contradiction to renewable energy opponents who say that renewable energy is too expensive: “the added renewable generation in this sensitivity results in lower market prices in many hours [of the year].”  This means that when real-world assumptions are used for our various sources of power, wind and solar are highly competitive with natural gas. In turn, that competition from renewables results in lower power prices and lower water use for Texas.

As state leaders look for ways to encourage new capacity in the midst of a drought, it’s important to realize that renewable energy is now competitive over the long term with conventional resources.  The fact that renewable energy resources can reduce our water dependency while hedging against higher long-term prices means that however state leaders decide to address the energy crunch, renewables need to be part of the plan.
