A Stealth Tool to Modernize the Electric Grid

Cyber-securityElectricity regulators, clean energy innovators, and rappers have all lamented poor communication. And some have pushed for cleaner, cheaper, more reliable solutions for meeting our energy needs. This is particularly so with the much anticipated emergence of a new kind of non-event based, price-responsive demand response (DR), or flexible DR.

Whereas traditional DR signals customers to voluntarily and temporarily reduce their energy use at times when the electric grid is stressed, this type of DR does that and more. The big difference? It signals customers, their appliances, and their electric vehicles to increase their energy use when electricity is clean, plentiful, and cheap.

For example, electric vehicles can be programmed to charge at mid-day when the sun is bright and solar energy is at its peak, and use that stored energy when the sun sets. Better yet, many of our cars, homes, and appliances can be programmed to monitor grid conditions in real time, via the Internet, and respond accordingly by charging or defecting. Also known as a “set-it-and-forget-it” feature, this function enables the seamless integration of flexible DR while also supporting the full potential of energy efficiency measures and distributed energy resources (DERs), like rooftop solar and energy storage.

California Makes Clean Energy History with Passage of SB 350

By: Lauren Navarro and Tim O’Connor

SolarPanels_iStock_000009912571_RFEvery day thousands of Americans suffer from dirty air – costing the young and old their health, livelihood, and in many cases, their lives. As California is home to the top five most polluted cities in the country, we need action.

Thankfully, after many long hours of debate and negotiations at the state capitol, the California Legislature passed SB 350 (De León) last Friday. The California State Assembly passed the bill, with a 52-26 vote with bipartisan support before passing it on to the senate where it was approved in a concurrence vote. This bill increases California’s renewable energy mix to 50 percent and doubles the energy efficiency of existing buildings. Both of these provisions will serve to combat dirty air and fight climate change, while ushering in a new era for the state’s electricity system – one defined by a cleaner, more resilient, and dynamic electric grid.

Renewable Electricity is in Bloom in California

solar flower sterling college flickrWhile California never quite got a winter, we can still acknowledge that spring – with the sun shining and flowers blooming – is here. From where I sit in Sacramento, spring means allergy season, getting out and enjoying the blue skies, a last bit of cool air before a brutal summer, and oh yes, the legislature heating up on important questions of California’s energy future.

This year, all eyes are on the question of how to meet the bold challenges laid out by Governor Brown  in his January inauguration speech, which set goals for: 50 percent of electricity to come from renewable energy, a 50 percent improvement in the energy efficiency of existing buildings, and a 50 percent reduction in petroleum use, all by the year 2030.

To answer that challenge, the Senate has introduced Senate Bill 350 (De Leon) and the Assembly has introduced Assembly Bill 645 (Williams, Rendon), both aimed at increasing the existing Renewable Portfolio Standard (RPS) from 33 percent to 50 percent by 2030. And, both bills are feeling the love from a diverse array of supporters. The April 7th Senate committee hearing on SB 350 enjoyed a line of supporters (including Environmental Defense Fund) which spilled into the halls! AB 645 saw a comparable showing when it was in committee on April 20th. Both bills will be discussed for the second time in committees this week.

This strong support for clean energy should come as no surprise – robust renewable energy policies can support job growth, reduce pollution, and attract clean energy businesses to the state, which is why groups representing working people, the environment, and the transition to a clean energy economy showed up “en masse” to demonstrate support. At the same time, these groups are having conversations amongst each other and with the legislature about exactly what the transition to an electricity grid that runs on 50 percent clean resources will look like. Why? Because the details matter. Read More »

Hitting Those Clean Energy Notes

Editor's note: This post was updated April 9, 2015.

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.
