Sunverge, Stem ink behind-the-meter storage deals in Japan

Two California-based energy companies, Stem and Sunverge Energy, have inked energy storage deals in Japan, working with Mitsui & Co., Ltd. on behind-the-meter aggregation in the service territory of Tokyo Electric Power Co. Stem and Mitsui say they are building one of Japan's first aggregated fleets of industrial customer-sited energy storage. The companies will deploy 750 kWh across multiple sites in TEPCO's service territory.

Blockchain: the ledger that will record everything of value to humankind

The internet is entering a second era that’s based on blockchain. The last few decades brought us the internet of information. We are now witnessing the rise of the internet of value. Where the first era was sparked by a convergence of computing and communications technologies, this second era will be powered by a clever combination of cryptography, mathematics, software engineering and behavioural economics. It is blockchain technology, also called distributed ledger technology.

Why the rise of electric vehicles will mean more to utilities than just increased electricity sales

That was the extent of global electric car stock as a percentage of all passenger light-duty vehicles in circulation at the end of 2016. It’s a tiny fraction in the context of the estimated 1 billion plus cars on the road. But with the total number of electric vehicles (EVs) doubling from 1 million in 2015 to over 2 million in 2016, the pace of EV adoption is clearly accelerating.

Lithium Price Spike Has Moderate Effect on Batteries

Battery prices have fallen in the past 12 months even as prices of lithium carbonate, or LCE, rose between 24-55 percent, and the cost of cobalt doubled. This may not last through next year. While battery prices have continued to fall, from $273/kWh in 2016 to $209/kWh this year, rising commodity prices could have more of an effect in 2018, when price spikes begin to filter through to battery makers, according to the latest analysis from Bloomberg New Energy Finance.

Smart Grid, Smart Inverters for a Smart Energy Future

Smart grid infrastructure can provide the technology necessary to reliably attain high levels of solar integration in the United States’ electric grid—so what, exactly, is a smart grid?  The electric power infrastructure in the United States—also known as the grid—is an engineering marvel, with more than 1 million megawatts of generating capacity and over 300,000 miles of transmission lines that provide power to residents in urban New York City and rural Wyoming alike.
