Schooling Demand Response in Texas Academia

By: Corina Solis, graduate of Yale University’s School of Forestry and Environmental Studies

2014-training-yale-cropThe Alamo Colleges began participating in local utility company, CPS Energy’s Demand Response Program in the summer of 2013. This Demand Response Program is one of CPS Energy’s strategies to achieve its 2020 goal of saving 771 megawatts of energy. The Alamo Colleges participated in the program in order to take advantage of a significant rebate opportunity, which was a maximum of $120,600 in 2013 and is $130,650 in 2014. Rebates are based on the level of participation, and in 2013, the Alamo Colleges earned rebates totaling $103,000. Through a self-funding strategy, all of this money went back to the Alamo Colleges to pay for faculty and staff salaries.

As an extra benefit, while saving all of this money, the Alamo Colleges trim their carbon footprint each time they participate in demand response. Last year, the Alamo Colleges prevented 2,250 lbs. of CO2 from going into the atmosphere from its demand response participation. This year, the Alamo Colleges are contracted to prevent up to five and a half tons of CO2 from escaping into the atmosphere, which would otherwise take 140 tree seedlings ten years to naturally take out of the atmosphere.

Red River Rivalry: What Oklahoma Gas & Electric can Teach Texas Utilities

800px-Red_River_Shootout_2006Fall is in the air, the State Fair of Texas is in full swing, and the annual meeting of the University of Texas (UT) and the University of Oklahoma (OU) will occur at Dallas' Cotton Bowl this weekend. One of the greatest football rivalries in the Big 12, UT and OU have been battling it out since 1900. Even the governors of both states frequently place bets on the game, like the losing governor having to present a side of beef to the winning governor.

And, while Sooners and Longhorns may not easily take advice from each other, Texas utilities should take a few lessons from Oklahoma Gas & Electric (OG&E). OG&E is Oklahoma's regulated utility serving over 800,000 customers in Oklahoma and western Arkansas.

Here in Texas, we are proud of many things from our "don't fence me in" ethos and wide-open landscapes to our self-reliance and abundant natural resources. Not too many states have the type of pride that Texas possesses (kitschy or otherwise). That pride extends to our innovative energy utilities as well, like Green Mountain Energy, Austin Energy, and CPS Energy in San Antonio, all of which are helping lead the state into the new energy sphere.

EPA’s State-by-State Carbon Limits Indicate Smart Policy, Not Arbitrary Rulemaking

EDF_FB_renewableEnergy_solar (1)In June, U.S. Environmental Protection Agency (EPA) announced – for the first time ever – standards to limit carbon emissions from U.S. power plants, known as the Clean Power Plan (CPP). Currently power plants emit 40 percent of U.S. carbon emissions, but under the proposed Clean Power Plan, the U.S. power sector will cut carbon pollution by 30 percent below 2005 levels.

Since this announcement, the usual suspects have attacked the CPP, calling its proposed state-by-state reduction standards arbitrary. Their claims couldn’t be further from reality. When EPA asked states for feedback on how to best craft this standard, states asked for two things: individual standards and flexibility. And that’s what they got. Anyone familiar with the proposed standards will know they are based on a consistent and objective methodology that takes into account each state’s unique energy portfolio and emissions, as well as built with maximum flexibility in mind.

At first glance, the climate-change-denying crowd dismissed the standards as arbitrary, because the limits vary from state to state. For example, Washington needs to reduce its emissions rate by 72 percent by 2030, while Kentucky only needs to cut its emissions rate by 18 percent over the same period. Texas lies somewhere in the middle with a 39 percent reduction required. So what gives? Read More »

Enough Drama, Texas has a Roadmap to Cut Pollution and Grow its Economy

They say everything is bigger in Texas and often that's true, especially when it comes to big hair and the bravado of politicians. This amounts to a lot of drama and theatrics. I mean, as someone who grew up in Dallas, I can tell you that the soap opera by the same name wasn't too far off the mark.

Being a mighty oil and gas (and wind!) state, this drama often translates into fights with the US Environmental Protection Agency (EPA) and other environmental regulators over pollution reduction. Texas is the number one emitter of carbon emissions and second biggest water-polluter in the nation. Texas doesn't really have solid ground to stand on.

Yet as of 2012, Texas Attorney General Greg Abbott (current GOP and Koch-brothers backed candidate for Governor) has sued the federal government over environmental regulations sixteen times. And of the 25 total lawsuits pending against the federal government, Texas has only prevailed five times. Exemplified yet again in June when the Supreme Court ruled seven to two that yes, in fact, EPA is allowed to regulate greenhouse gas emissions from most large industrial facilities, like power plants and factories, despite Texas’ arguments.

The Cheapest Way to Cut Climate Pollution? Energy Efficiency

This blog post was written by Lauren Navarro, Attorney and California Senior Manager, Clean Energy, and co-authored by Kate Zerrenner.

On June 2, the U.S. Environmental Protection Agency made a historic announcement that will change how we make, move and use electricity for generations to come.

For the first time in history, the government proposed limits on the amount of carbon pollution American fossil-fueled power plants are allowed to spew into the atmosphere.

There are two clear winners to comply with the plan while maintaining commitment to electric reliability and affordability: energy efficiency and demand response.

We’re already seeing pushback from some of our nation’s big polluter states, such as West Virginia and Texas. But the truth is that while the proposed limits on carbon are strong, they’re also flexible.

In fact, the EPA has laid out a whole menu of options in its Clean Power Plan – from power plant upgrades, to switching from coal to natural gas, and adopting more renewable energy resources. States can choose from these and other strategies as they develop their own plans to meet the new standards.

That said, there are two clear winners on the EPA’s menu that offer low-cost options for states that seek to comply with the plan while maintaining their commitment to electric reliability and affordability: energy efficiency and demand response. Read More »

Power Plant Rule a Tipping Point for Clean Energy Economy

powerplantrule

By: Cheryl Roberto, Associate Vice President, Clean Energy

For those of us (and all of you) who’ve been urging the government to implement meaningful climate policy, the release yesterday of a plan to cut carbon emissions from power plants has been a long time coming. But it finally came.

The U.S. Environmental Protection Agency’s proposed carbon pollution rule for existing fossil-fueled power plants – also known as the Clean Power Plan – are a huge win for our climate.

We also think it could go down in history as the tipping point in our nation’s transition to a clean energy economy. Here’s why:

Old, dirty power plants will be retired

The nation’s fleet of coal-fired power plants is the single largest source of carbon pollution in the U.S. and one of the largest in the world. Placing carbon regulations on this source of electricity for the first time in history will transform our energy system. Read More »

With the recent release of the National Climate Assessment, the threat of climate change has never been clearer. Addressing this will require a fundamental transition away from fossil-fuel sources of energy in favor of renewable energy technologies like wind and solar power. Electric utilities vary in their progress towards delivering a future powered by clean energy. Notably, Central Texas, with its combination of energy know-how, creative thinking, and technology entrepreneurship, is home to many utilities leading the way in clean energy resources and smart grid technology.

Austin & San Antonio are leading the pack

Although Texas has a deregulated, competitive electricity market where most energy companies compete for customers, the San Antonio-Austin-Hill Country corridor is mainly comprised of public electric utilities, like municipals and cooperatives that are community-owned. For years, Austin and San Antonio’s municipal utilities have benefited from an engaged customer base that cares about the transition to a clean energy economy. Read More »

Can Texas Keep the Lights On? Clean Energy Holds the Answer.

rp_Final-Images-EDF-6524-200x300.jpgOn Tuesday, I had the pleasure of participating on a panel hosted by the Texas Tribune that centered on the future of Texas’ power grid and electric reliability. Joining me was John Fainter, president and CEO of Association of Electric Companies of Texas, Inc; Trip Doggett, president and CEO of the Electric Reliability Council of Texas; and Doyle Beneby, president and CEO of CPS Energy, San Antonio's municipal utility. The panel, entitled Keeping the Lights on in Texas, took place at and was broadcasted from St. Mary’s University in San Antonio. It's a worthwhile watch and I'm encouraged that Texas Tribune is dedicated to investigating Texas' energy issues.

For about an hour, we discussed a variety of aspects in the current and future energy landscape of the Lone Star State. In particular, I focused on the exciting shift to give people power over their electricity use, save money, and help the environment with every flip of the switch.

Demand Response: People, not New Power Plants, are Driving the Clean Energy Future

By: Cheryl Roberto, Associate Vice President, Clean Energy

Clean energy resources, like wind, solar, and energy efficiency, have certain key advantages over traditional, fossil fuel-based resources: they don’t require expensive, polluting fuels or large capital investment, consume little to no water, generate negligible carbon emissions, and are easily scalable. To take full advantage of low-carbon, renewable energy sources, we need a power grid with enough flexibility to harness clean energy when it is available and abundant. That’s where demand response, a people-driven solution, comes in.

On a hot summer day, for example, electricity use rapidly increases as people turn on air conditioners to avoid the heat of the late afternoon. A decade ago, the grid operator’s only option is to turn on another fossil fuel power plant to meet the increased need for electricity. But, at any given time, there are thousands of light switches left on, idle water heaters, cycling swimming pool pumps, and forgotten thermostats that people could temporarily turn off or down, if only they were offered the right incentive. If asked, people can adjust their power usage in exchange for a financial reward. We call this “demand response,” and it is increasingly helping to balance the flow of electricity with our energy needs at a given moment.

Demand response diverts money that would generally go to a fossil fuel power plant to homeowners and businesses instead. In this scenario, a utility or demand response provider sends a message for participants to reduce electricity use at key times in exchange for a credit or rebate on their utility bill, in addition to the cost savings they will earn through conservation. Of course, participants always have the option to opt-out with the tap of a button on their smart phone or thermostat. Read More »

UPDATE: Demand Response Helped Texas Avoid Rolling Blackouts in the Face of Polar Vortex

Good news for clean energy in Texas!

Source: KXXV

Source: KXXV

The Electric Reliability Council of Texas (ERCOT), Texas’ power grid operator, presented a report recently confirming what we already knew: demand response is a worthwhile investment that strengthens Texas' power grid.

Demand response is an innovative tool used by utilities to reward people who use less electricity during times of peak, or high, energy demand. In effect, demand response relies on people, not power plants, to meet the demand for energy. And on January 6th when the Polar Vortex hit Texas, it did just that.

Demand response kept the lights on in Texas by providing more than 600 megawatts of power to the electric grid within 45 minutes. Again on January 18th, demand response came to the power grid’s rescue, when a malfunctioning power plant failed to provide electricity despite mild temperatures and fairly low power demand. As noted before, this report highlights events that occurred during the winter of this year, at a time when Texans do not typically expect the power grid to be strained, unlike the summer. This means that a reduction in energy use – or negawatts – was able to stabilize the electric grid such that blackouts were avoided.

As shown in the report, ERCOT's Emergency Response Service is a reliability mechanism used during extreme events when the power grid is at risk of rolling blackouts. Part of the program is the procurement of demand response, which was only in the pilot phase last year, but has now been formally adopted. This program was utilized during the extreme weather events this winter and relied on the participation of hundreds of Texas businesses, schools, local governments and individuals. Read More »
