Elon Musk: Demand for Tesla batteries ‘has been really crazy’ | Utility Dive

“If you just take the reservations that have been made thus far, it’s well over $1 billion worth of Powerpacks and Powerwalls,” he said. “And that’s with no marketing, no advertising, no sales force to speak of, really. We’re not trying to sell it. It’s basically a presentation and a webcast and 30 minutes of press Q&A. … So there’s probably room to improve.” Source: Elon Musk: Demand for Tesla batteries ‘has been really crazy’ | Utility Dive

SolarCity adds Tesla battery to its new solar-plus-storage home product | Utility Dive

“The Tesla 7 kWh battery costs $7,000 installed and is meant to be cycled daily,” Tucson Electric Power’s Carmine Tilghman recently told Utility Dive. “At the average all-in electricity rate of $0.12 per kWh, the buyer saves $0.84 per day. And $7,000 divided by $0.84 per day means it will take 8,333 days or about 22.9 years to get the initial investment back for a battery that comes with a ten year warranty.” Source: SolarCity adds Tesla battery to its new solar-plus-storage home product | Utility Dive

Storage update: Inside the sector’s hot Q1 and what’s next for utilities & suppliers | Utility Dive

June 12, 2015 // 0 Comments

First quarter numbers are often unimpressive because companies tend to put more effort into planning than building in the first three months of the year. But the U.S. deployed 5.8 MW of storage in Q1 2015, 16% more than Q1 2014. Utility-scale, in-front-of-the-meter storage, the sector’s biggest component, added 4.2 MW in six projects. Behind-the-meter (BTM) storage had its biggest Q1 ever, with 1.6 MW of capacity installed, a jump of 132% from Q1 2014.

Innovative battery technology can benefit utilities | The Big Data Hub

June 9, 2015 // 0 Comments

IBM’s Jennifer Potter published a post about energy storage and the possible benefits for utilities: Tesla’s Powerwall Home Battery seems poised to wean consumers off the big grid. A recent TechCrunch article claims that a single battery pack, valued at $3,000, will let a household run entirely on solar energy. On the other hand, Wired’s Rhett Allain challenges these claims by explaining the physics of energy storage. According to Allain, a single 10 kWh Powerwall could not meet the electricity demands of a typical household. Surveys conducted by the U.S. Energy Information Administration average typical household use at 30 kWh a day, therefore, a customer would need three Powerwalls to stay off the grid entirely. Three powerwalls can be arranged, but this would only work for sunny states and countries. I don’t think that west- and nordic European countries have enough sunshine in the winter to even supply themselves with solar power.

Massachusetts Pushes to Become Energy Storage Leader with $10M Plan – Microgrid Knowledge

May 31, 2015 // 0 Comments

Massachusetts signaled today that its new administration plans to continue the state’s march into the world of microgrids and other disruptive energy tech with plans for a $10 million energy storage program.The previous administration of Gov. Deval Patrick (D) helped make the state a green-energy leader, including maintaining a multiple-year top national ranking for energy efficiency. Since Patrick left office in January, energy industry insiders have been watching new Gov. Charlie Baker (R) for a sense of how he’ll model the state’s energy future.
