Electric Reliability and the Clean Power Plan: Perspectives of a Former Regulator

rp_2Wind_Turbines_and_Power_Lines_East_Sussex_England_-_April_2009-300x204.jpgThere is no great disagreement that the U.S. energy system is transforming. With or without additional environmental regulations, like the U.S. Environmental Protection Agency’s (EPA) proposed Clean Power Plan, this transition is occurring. Our history and experience have demonstrated that we can weather it without threatening our uniform and non-negotiable commitment to reliability.

But to do that, we need to tap all of the tools at our disposal to ensure a robust, reliable, and integrated energy system that is no longer dependent exclusively upon centralized, fossil fuel generation. Done right, the resulting change can deliver benefits to customers, the economy, the environment, electric companies, innovators, and workers alike.

EPA’s proposed Clean Power Plan would place national limits on carbon pollution from existing fossil fuel power plants for the first time ever. In doing so, it would create long-term market signals that will help drive investments in energy efficiency, demand response, and renewable energy for years to come – not only reducing carbon pollution from the power sector to 30 percent below 2005 levels by 2030, but also by putting us on a path to a more reliable and resilient energy system.

2014: A Positive Sign of What’s to come for Clean Energy

Photo by DAVID ILIFF. License: CC-BY-SA 3.0The New Year is a time for reflection, beginning with a look back on the previous 12 months and all that they brought. A quick scan of the U.S. climate and energy news in 2014 will tell you it was a very big year.

The Environmental Protection Agency (EPA) proposed the first-ever limits on carbon pollution from power plants, the U.S. and China struck a historic climate deal, and Tesla broke ground in Nevada on the largest advanced automotive-battery factory in the world – a  move that’s expected to slash the cost of lithium ion batteries by a third. At the same time that these important national and international advancements were grabbing headlines, Environmental Defense Fund (EDF) and our partners were working together to incrementally transform the U.S. electricity system by rewriting outdated regulations, spurring energy services markets, and modernizing our century-old electric grid.

The U.S. is on the verge of a revolution in the way we make, move, and use energy. And, having spent years working on governmental and regulatory matters related to our power system and lessening its impact on the environment, I can honestly say there has never been a more exciting time to be in this field. Here are a few of the moments that were near and dear to our hearts over the past year, developments I see as a sure signal 2015 will be another epic year for clean energy. Read More »

The Clean Power Plan: Protecting Health and the Climate While Ensuring Electric Reliability

The U.S. Environmental Protection Agency’s (EPA) new Clean Power Plan will empower states to design customized, cost-effective programs to reduce climate-destabilizing pollution while ensuring continued electric system reliability.

States will be able to deploy flexible compliance mechanisms such as:

  • renewable energy
  • demand-side energy efficiency
  • shifts in utilization away from higher-emitting and towards lower-emitting generation sources
  • measures at specific plants to secure reductions in carbon pollution

And states will be able to do all of this while designing their compliance plans to make sure that generation resources are fully sufficient to ensure reliability. Read More »

Power Plant Rule a Tipping Point for Clean Energy Economy

powerplantruleFor 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 »

U.S. Climate Assessment Report Warns of Energy Challenges – All of which We’re Ready to Meet

There’s been plenty of attention paid to the recent release of the Third National Climate Assessment report – and appropriately so. The lead paragraph of New York Times reporter Justin Gillis’ story put it rather bluntly:

“The effects of human-induced climate change are being felt in every corner of the United States, scientists reported Tuesday, with water growing scarcer in dry regions, torrential rains increasing in wet regions, heat waves becoming more common and more severe, wildfires growing worse, and forests dying under assault from heat-loving insects.”

Even for those of us that have been urging U.S. action on climate, the assessment was pretty stark and the message was clear: the time to act came a long time ago. We need to get busy catching up.

But the optimist in me was excited about a chapter in the report that hasn’t yet gotten much attention. Chapter 4 focuses on Energy Supply and Use, and though the energy challenges caused by climate change are formidable, the U.S. is very well positioned to meet them if our leaders will get behind some practical solutions. There are five key takeaways in the Energy chapter: Read More »

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

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 »
