Demand Response: Power For The Grid Starts With The People

Earlier this month, I had the opportunity to speak on a panel entitled, Resource Adequacy & Demand Response: Ensuring Texas’ Future Reliability at the 7th Annual Platts Texas Energy Markets Conference in Houston, TX.  Following fellow panelists, “Trip” Doggett, CEO of ERCOT; Milton L. Holloway, President and COO of the Center for the Commercialization of Electric Technologies; and John W. Fainter, Jr. President and CEO of the Association of Electric Companies of Texas, I spoke about EDF’s work with the Pecan Street Research Institute  (Pecan Street) to test and deploy various smart grid consumer products.

One of the many cutting-edge research projects being conducted by Pecan Street is an examination of consumer behavior with regards to energy usage.  Trends in the data show that giving people the ability to control their energy use, and their energy generation, generally results in cost-effective, environmentally-conscious decisions. These shrewd decisions are becoming increasingly important as Texas faces a lack of energy resources to meet the state’s increasing need for more electricity.

With July just around the corner, the summer heat is ramping up in Texas, and the Electric Reliability Council of Texas (ERCOT) is preparing for extreme temperatures to push the electric grid to its limits.  State regulators and ERCOT stakeholders are urgently seeking a solution to the looming Texas Energy Crunch.  The Public Utility Commission of Texas (PUC) has already raised the maximum price in the electricity market a number of times, but this is a band-aid for the problem, not a long-term solution.

Environmental Accomplishments And Missed Opportunities From The 83rd Texas Legislative Session

This blog post is co-authored by Marita Mirzatuny and Kate Zerrenner.

In addition to passing tax cuts and making pecan pie the official state pie of Texas, the 83rd Legislature heard numerous energy-related bills.  As a solution to our Texas Energy Crunch efforts, EDF supported 13 bills that would have provided relief to Texas’ resource adequacy problems; in other words, the issues Texas faces as a result of increasing energy demand, scorching temperatures and a record drought.  Among those bills (which we review on page 13 of our ‘State of the Texas Energy Crunch’ report) are a few, highlighted below, that made some – albeit not enough – progress.

Energy Legislation

A big success this session was the passage of Senate Bill (SB) 385 by Chairman John Carona.  SB 385, or the Property Assessed Clean Energy (PACE) bill, clears some of the hurdles that prohibit commercial and industrial properties from taking advantage of new financing for energy improvements.  PACE allows property owners to pay for water and energy efficiency upgrades or renewable energy improvements with loans, which are then repaid through an annual charge on their property tax bill.  For more on this legislation, please see our recent blog post covering PACE in Texas.

Chairman Carona’s demand response bill, SB 1351, passed and was referred to State Affairs in the House.  Demand response (DR) initiatives allow customers to voluntarily reduce peak electricity use and receive a payment for doing so in response to a signal from their utilities.  Additionally, Chairman Rafael Anchía introduced the companion bill, House Bill (HB) 2194.  HB 2194 allows for customer, or demand-side resources (DSR), from “residential, commercial, and industrial customers to participate in all energy markets” and specifies that DSR “must be designed and implemented in a manner to increase market efficiency, competition, and customer benefits.” This bill clears the way for demand response, renewable energy, and energy efficiency to become important players in the market.

SB 1280, by Senator Kirk Watson, passed out of the Business and Commerce Committee with a seven to two vote.  This bill, regarding Texas’ reserve margin for the electric grid, requires that power regions (such as the Electric Reliability Council of Texas, or ERCOT) estimate the available generation at any given time, the expected peak demand (demand at the hottest part of the day when the most energy is being used) and the amount of reserve energy needed to ensure a reliable electricity supply.  SB 1280 also directs the use of voluntary load participation programs (think demand response) with at least 20 percent of peak energy demand coming from each of the residential, commercial and industrial sectors.

Senator José Rodríguez’s net metering bill, SB 1239, successfully passed out of the Business and Commerce committee.  Texas is one of only seven states where customers are not guaranteed fair compensation for the electricity they provide to the grid.  SB 1239 clarifies that all retail electric providers, municipal utilities and cooperatives must buy back extra electricity from residential customers along with churches and schools at a reasonable, market-based value.  For example, Los Angeles implemented the largest solar buyback program in the nation earlier this year, paying customers 17 cents a kilowatt hour for excess energy produced.

In the House, HB 303 by Representative Eddie Rodriguez called for a new renewable energy goal – to supply 35 percent of energy demand with clean energy by 2020, with at least two percent coming from solar.  This marks an important precedent for the clean energy standards introduced in state legislatures around the country.  Additionally, Representative Rafael Anchía authored HB 2196, a bill that addresses payments to customers for renewable energy and other demand-side contributions to the electric grid.

While it’s great that some of the bills gained some traction, only SB 385 made its way to the Governor’s desk.  With a hotter than average summer approaching, possibly worse than 2011, electric reliability is not a guarantee and these bills would have provided solutions to help address our energy issues.  Already Texas is receiving national attention for our impeding energy shortages.

Water Legislation

At the last minute, the House and Senate, after much back door negotiating and out front wrangling, approved a plan to fund the State Water Plan.  HB 4, by Chairman Allan Ritter, set up two funding accounts to pay for water projects.  These accounts must be approved by voters, because the bills would amend Texas’ Constitution to allow the plan to be initially funded with a portion of the Rainy Day Fund.

Don’t Be Fooled By Recent Lows: The Texas Energy Crunch Is Still A Big Issue

This past month, we experienced refreshing, cool and somewhat wet weather in Texas.  However, those working on energy issues know all too well that this weather change doesn’t mean we have escaped the worst of the “energy crunch.”  As the farmers say: “If you don’t like the weather in Texas, wait ten minutes and it will change.”  Despite cooler temperatures, an unplanned power plant outage during a warm day late last month forced the Electric Reliability Council of Texas (ERCOT) to issue an advisory, demonstrating just how quickly things can change.

At the same time, recent ERCOT reports indicate that reserves will be tight this summer due to an anticipated record level of high energy demand and stunted growth in new electricity resources – thus making conservation notices likely and rolling outages probable.  All of this points to the important role conservation programs, like demand response, can play for ERCOT.  Some ERCOT staff and stakeholders have recognized the importance of demand response, which allow customers to voluntarily reduce electricity use in response to a signal from utilities.  Others have called explicitly for programs that pay customers for reducing energy the same way generators are paid for producing energy, an approach EDF has advocated for several years.

ERCOT and a few retail electric providers already have conservation programs, albeit limited, in pilot phases that compensate customers for their participation.  But in comparison to other regions, Texas lags far behind other states – despite having the highest potential for conservation and clean energy resources in the U.S.  That’s why the three remaining weeks of the legislative session are so important: two critical pieces of legislation that would open up demand response in Texas to meet our electricity reliability goals and drive further market competition are under review.

Senate Bill (SB) 1351 from Senate Business & Commerce Chairman John Carona would require ERCOT to allow customers to participate in all competitive energy markets; the bill passed the Senate earlier this week and is now on its way to the House of Representatives.  SB 1351 is an excellent piece of legislation to propel demand response in Texas, but alone it is not enough to ensure Texas can keep the lights on during the hottest summer days.  A separate bill from Senator Kirk Watson, Senate Bill (SB) 1280, would accomplish just that by requiring ERCOT to secure enough demand response to meet its reliability needs if existing resources fall short; the bill passed unanimously out of the Senate Business & Commerce committee.

These bills will make all the difference this summer and for many summers to come.  The Texas Legislature has the opportunity to ensure that ERCOT and the Public Utility Commission (PUC) have all the necessary tools to avoid rolling blackouts over the next several years as we wait for new energy resources to come online.

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.

Do We Need Breakthroughs Or A Simple “Carbon Diet?”

Over the weekend, The New Republic published an interview with President Obama, where he noted the following: “On climate change, it’s a daunting task. But we know what releases carbon into the atmosphere, and we have tools right now that would start scaling that back, although we’d still need some big technological breakthrough.”  How accurate is the call for breakthroughs and what do we really need?

First, let’s look at where we don’t need breakthroughs, but instead more deployment – energy efficiency, of course, being Exhibit A.  Creative financing, such as on-bill repayment (OBR), at scale can speed up deployment here.  Similarly, unlocking clean energy to reduce carbon emissions from the electricity sector hinges on affordability.  Wind energy is already competitive with fossil fuels, in large part because the cost of wind energy has come down around 65 percent in the last 20 years, according to the National Renewable Energy Laboratory (yes, declining natural gas prices provide new competition, but EIA projects that natural gas prices will begin to increase in 2018, and wind power purchase agreements are signed for around 20 years at a fixed price).  Residential solar is verging on the tipping point for “grid parity,” or the point at which a source of power becomes cost competitive with other sources.  Bell Labs first introduced solar cells in the 1950s.  Environment California’s Research & Policy Center recently reported that they expect solar to reach grid parity in mid-2014 to 2016 at the outset. 

Of course, progress in lowering costs and increasing efficiency comes on the heels of many smaller innovations.  For example, innovations in materials science underlie many of the most promising technology evolutions, such as the role of carbon fiber as a basic raw material for wind turbine blades or the use of Gallium Arsenide wafers to reduce manufacturing costs for solar cells.  But, nonetheless, given our country’s strength in materials science (think of our leadership with companies like Dow, Dupont and 3M), such innovations seem imminently feasible and in my mind don’t require a major “breakthrough.” 

We’ve also delivered numerous hardware and software innovations to transform our electric grid into a more resilient, smart, “green” grid.  Even carbon capture and storage, to some a high stakes technology bet, is actually just a new configuration or application of engineering equipment we have installed and used for decades, such as heat exchangers, chillers, absorbers, pumps and compressors.

Where would I wave a wand for a breakthrough?  A cheap, reliable and efficient energy storage system wouldn’t hurt, one that replaces the clunky compressed air systems or the size limitations of batteries.  But, overall, the declining cost curves for clean energy solutions, due to innovations large and small, tell us an important story:  solving the climate crises is not unaffordable or necessarily a drag on our recovering economy as many fear.  It is certainly not infeasible nor hinging on that one great technological breakthrough. 

We need non-technological breakthroughs.  Like the new head of the World Bank, Dr. Jim Kim, who in Davos described wanting to make “everything the Bank does aligned with the effort to slow down climate change.”  And it is certainly cheaper than repeating the $50 billion recovery price tags that we might face time and again as Superstorm Sandy becomes the new normal. 

Americans love the quick technical fix.  But, today we have affordable answers right in front of us, it’s the willpower we may be lacking.  So, just as most of us believe that rather than wait for a dieting breakthrough, the best answer to weight loss is reduced consumption and more exercise – we need to go on a carbon diet.  Our economic and environmental health depend on it.
