What Tesla’s Powerwall Home Energy Storage Battery Means for Texas

There is enough solar energy potential in Texas to power the world twice over. Yet currently we rank 10th in the nation (behind New Jersey) with 330 megawatts (MW), which is enough to power about 57,000 homes. Texas is a state of almost nine million households. That’s a lot of rooftops, and when you add the number of commercial and industrial rooftops, parking lots, and garages, we are talking about a significant amount of surface area.

Meanwhile, the cost of solar panels has dropped 80 percent since 2008 and prices for rooftop photovoltaic (PV) systems have declined markedly in recent years, dropping 29 percent from 2010 to 2013. Moreover, jobs in the solar industry are booming –SolarCity is hiring significantly more people than leading tech companies like Twitter.

So, what will it take to energize rooftop solar growth in Texas? Well, a recent announcement from one of Texas’ “frenemies” may be part of the solution. Read More »

So You Want an EV? We’re Helping to Figure Out How to Make it Happen

By Larissa Koehler / Published: May 8, 2015

You may have noticed: we’re big fans of electric vehicles (EVs) here at Environmental Defense Fund (EDF). Standard transportation fuels are one of the biggest sources of harmful greenhouse gas emissions, so vehicle electrification is a crucial part of our clean energy future. But getting more EVs on the road is about more than just giving customers incentives to buy these types of vehicles. We also need to deal with where and how we charge EVs.

From April 27^th to May 4^th, EDF was engaged in evidentiary hearings at the California Public Utilities Commission that dealt with San Diego Gas & Electric’s (SDG&E) new electric vehicle pilot. Representatives from EDF, the Utility Consumers’ Advocacy Network, the Office of Ratepayer Advocates, SDG&E, Pacific Gas & Electric, ChargePoint, KnGrid, the Natural Resources Defense Council, and the Green Power Institute, were all putting their best foot forward at the hearings. While there were sadly no Perry Mason moments (aside from an unsilenced cell phone playing the theme song in the middle of the hearings), I did try my hand at challenging witnesses on some key points through cross-examination for the first time. More importantly, the six-day-long process allowed Jamie Fine to shine as an expert witness and raise a number of matters of high priority to EDF. Read More »

Creative Utility Accounting: Estimating the True Cost of a Subsidy

By Dick Munson / Published: May 7, 2015

$5 billion is a lot of money, yet that’s the difference in cost estimates between an Ohio-based, consumer advocacy group and FirstEnergy for the utility’s proposed bailout plan.

FirstEnergy, the giant Akron-based company that owns power plants and transmission lines in several midwestern and northeastern states, calculates its proposed plan to raise electricity rates will eventually save Ohio customers $2 billion. The Ohio Consumers’ Counsel, in contrast, estimates the subsidies will cost Ohioans $3 billion.

To appreciate the differences, consider a little history.

Several years ago, FirstEnergy thought it could profit in emerging regional electricity markets, so it convinced regulators to allow it to set up a separate subsidiary that would generate and sell electricity. That unit was to be independent from another subsidiary company, which managed the power wires and delivered power to customers. This partial step toward free markets, however, didn’t work out too well for FirstEnergy. Now, it’s asking regulators to abandon competition. Read More »

Are Apple and Google Disrupting America’s Century-Old Energy Market?

By Gavin Purchas / Published: May 6, 2015

Apple made news earlier this year when it signed an $848-million “direct access” deal to bypass Pacific Gas & Electric Co. and buy clean energy directly from a third-party solar provider. For Apple, the big win was a contract that locked in affordable energy for the next 25 years.

But the deal also set a historical precedent for corporate renewable energy purchases that may, over time, have huge financial implications for traditional utilities.

Energy deals break new ground

With its solar contracts, the iPhone maker is insulating itself from the price volatility that accompanies fossil fuels, in addition to getting power for less than half the cost. Going forward, it can count electricity as a fixed, predictable cost – an attractive proposition that is sure to spark interest among other large buyers of electricity.

Apple’s investment in First Solar’s PV Flats, a 2,900-acre solar array in Monterey, California, also suggests that corporations are ready to take procurement of energy to a new level.

On the heels of Apple’s deal came news that Google signed a 20-year purchase agreement to buy half of the energy produced at the soon-to-be refurbished Altamont Pass wind energy facility. The wind turbines there will power the company’s sprawling Googleplex headquarters in nearby Mountain View, California – again, effectively bypassing the local utility. Read More »

Matching Veterans with Solar Jobs: Now that’s a Bright Idea

By Stephanie Kline / Published: May 4, 2015

During the next five years, 200,000 service members will transition from active duty military to civilian life. They will need jobs. The solar industry is booming and needs skilled workers. The math is simple.

The recently announced Solar Ready Vets program aims to help transitioning service members pursue training in the solar industry, which is adding 30,000 jobs a year, according to the U.S. Department of Energy (DOE).

Solar Ready Vets will focus on the specific needs of high-growth solar employers and build on the technical skills that veterans acquired during service. Solar Ready Vets is part of a larger DOE initiative to train 75,000 people for the solar workforce by 2020, some of whom are also veterans.

Initially, Solar Ready Vets will roll out at 10 military bases across the United States. Four bases in Colorado, California, Utah, and Virginia have been identified, and the other six will be selected based on the number of transitioning military personnel and strength of the solar market, among other things.

Electricity Pricing: The Times, they Might be A-Changing

By Jamie Fine / Published: April 30, 2015

Last week, the California Public Utilities Commission (CPUC) issued a proposed decision on residential rate reform. Residential rate reform – how and what Californians pay for electricity – is a thorny subject, and the Commission’s proposed decision is being met with a range of reactions.

We at Environmental Defense Fund (EDF) want to highlight a bright spot in the 300-page document that we’re thrilled about: the attention paid to time-of-use electricity pricing (a type of time-variant pricing). Buried in this long legal document, we see EDF’s fingerprints in the Commission’s call for California investor-owned utilities to ramp up their use of this innovative yet well-proven pricing tool starting with pilots in 2016 and going to scale in 2019.

How TOU Works

If you’ve been following EDF’s work in this area, then you know we’ve been involved in this process for many years and have probably gathered that we’re big fans of time-of-use pricing (TOU) because it better reflects the true cost of electricity, which fluctuates throughout the day. This type of pricing also empowers customers to better control their own energy bills and reduce our reliance on fossil fuels.

TOU pricing works by breaking up the day into two or three large intervals and charges a different price for each. Rates can be divided into off-peak prices (generally during the middle of the night to early morning), semi-peak prices (daytime and evening), and peak prices (occurring during periods of highest demand, usually afternoon to early evening). These rates remain fixed day-to-day over the season.
