When the door to one power plant closes, a window to more clean energy solutions opens.

It may seem logical that once a power plant closes, another one needs to be built to replace it – after all, we need to make up for its potential energy generation with more natural gas or nuclear-powered energy, right? San Diego Gas & Electric (SDG&E) is certainly trying to convince Californians this is true. Trouble is, EDF and other environmental groups, along with the California Public Utilities Commission (CPUC), aren’t buying it. And you shouldn’t either.

This story begins in 2013, when the San Onofre Nuclear Generating Stations (SONGS) permanently closed, shutting down a nuclear power plant with a capacity of 2,200 megawatts (MW) and sparking a debate about how to replace this lost power source. When first determining how to proceed in the wake of the SONGS closure, the CPUC decided SDG&E could buy between 500 to 800 megawatts (MW) of new energy resources by 2022. Further, at least 200 MW of this power had to – and all of it could – be met with preferred resources like energy efficiency, renewable energy, energy storage, and demand response (an energy conservation tool that pays people to save energy when the electric grid is stressed).

Here Comes the Sun: How California is Bringing More Renewables to the Grid

rp_Larissa-Koehler-200x300.jpgAsk most people what the Beatles and California have in common and they might very well be at a loss. However, the answer is pretty simple: they are both unabashed trendsetters in the face of resistance – the former in their musical style and the latter in its clean energy policies.

Not content with setting a Renewable Portfolio Standard that ends at 2020, Governor Jerry Brown and state legislators are pushing for the Golden State to get 50 percent of its energy from renewable resources by 2030.

To meet this ambitious target, California must build a system that is largely based on renewable electricity, like wind and solar. This is not an easy task. The primary reason? Sunshine and wind are only available at certain times of the day and can be variable during those times.

Traditionally, managers of the electricity grid have relied upon dirty “peaker” power plants – usually fossil fuel-fired and only needed a couple of days a year – to balance the grid during periods of variability or when electricity demand exceeds supply. But, in a world where 50 percent of our energy comes from renewable sources as a means to achieving a clean energy economy, we can’t rely on these dirty peaker plants to balance the variability of wind and solar.

Luckily, technology is available today that can help fill the gap of these peaker plants – and the California Public Utilities Commission (CPUC) is starting to embrace it. Read More »

Demand Response: A Valuable Tool that Can Help California Realize its Clean Energy Potential

rp_Cover-photo-image-300x200.jpgA tool only has value if it’s used. For example, you could be the sort of person who’s set a goal of wanting to exercise more. If someone gives you a nifty little Fitbit to help you do that, and you never open the box, how useful, then, is this little device? The same is true about smart energy management solutions: good tools exist, but whether it’s calories or energy use that you want to cut, at some point those helpful devices need to be unpacked. The same is true for demand response, an energy conservation tool that pays people to save energy when the electric grid is stressed.

California's electricity industry stands at a crossroads. The state got an early start on creating laws and policies to cut carbon pollution, and is now reaping the benefits of these policies through reduced emissions and healthy economic growth. That said, California can’t cut carbon emissions and reduce its reliance on fossil fuels without having alternatives to choose from — some focusing on promoting renewable energy, others on smarter energy management tools. Demand response is one of these tools, and a critical one. This highly-flexible, cost-effective resource should play a key role in California’s clean energy future, but several barriers stand in the way of unleashing its full potential.

It’s hard to think of California as anything but forward-thinking, but, right now, the state’s demand response programs are lagging behind those in other states and regions of the country like the Mid-Atlantic. There is good news, however, because demand response is an evolving resource. And, with advances in smart grid technologies, demand response has the potential to improve our energy mix in California. In EDF’s new report, Putting Demand Response to Work for California, we offer recommendations on how to unlock demand response as an important part of the overall strategy for California’s bright energy future.

EDF is Calling for More Demand Response in California and Why You Should Too

This week the California State Assembly will consider Senate Bill 1414 (Wolk). What’s so exciting about SB 1414? This bill will accelerate the use of demand response (DR), a voluntary and cost-friendly program that relies on people and technology, not power plants, to meet California’s rising electricity needs.

DR programs compensate people and businesses who volunteer to use less electricity when supplies on the power grid are tight and/or to shift energy use when cleaner, renewable resources are available. Every time a customer participates in lowering their energy use through demand response, they are rewarded with a credit on their electricity bill.

The implementation of demand response will help catalyze a much needed upgrade to our outdated grid, whose fundamental design hasn’t been updated since Thomas Edison invented it over a century ago. Demand response can empower participants to lower their electricity bills and carbon footprints, improve air quality, allow for more renewable electricity, and enhance electric grid reliability. In a tree of options for modernizing and cleaning up our energy system, demand response is a low-hanging-fruit. Read More »
