        RWE Storage Acquisition a 'Strategic Fit'

        The chief executive of RWE, Peter Terium, says the pending acquisition of German solar and battery specialist Belectric Solar and Battery Holding perfectly complements the strategy the company is trying to achieve. Both the firms have signed a share purchase deal and agreed a purchase price in a high double-digit million euro range but the deal must wait for approval from EU anti-trust authorities before completion, something the company told Power Engineering International it sees as merely a formality. RWE Innogy CEO Terium said, “With innogy we are creating the innovative, decentralized and sustainable energy company of the future. The agreed acquisition of Belectric Solar & Battery fits this strategic orientation perfectly.” “Smart battery storage solutions make generating electricity from renewables both more efficient and more secure. We are acquiring an innovative company that has built up an international strong market position. We are now combining our complementary strengths and creating additional impetus to successfully implement our projects in Europe and our growth regions – the whole will be greater than the sum of its parts.”

        UK’s National Grid Goes Big Into Energy Storage With 201MW of Fast-Acting Batteries

        U.K. grid operator National Grid has just put its money behind one of the world’s single largest procurements of energy storage. Late last week, the owner and operator of the transmission grid in England and Wales announced 201 megawatts of winning bids of its first-ever tender for “enhanced frequency response.” Out of a list of some 64 pre-qualified bidders, National Grid picked eight vendors with a combined 201 megawatts of projects, ranging in size between 10 and 49 megawatts apiece, with a total value of £66 million ($86.4 million).

        U.S. Senators Propose Tax Credit for Energy Storage

        U.S. Senator Dean Heller issued the following statement after becoming a cosponsor of S. 3159, the Energy Storage Tax Incentive and Deployment Act. The legislation, introduced by Senator Martin Heinrich (D-N.M.), a member of the Senate Committee on Energy and Natural Resources, establishes investment tax credits (ITC) for business and home use of energy storage. The bipartisan bill was also cosponsored by Senators Brian Schatz (D-Hawaii), Al Franken (D-Minn.), Jeff Merkley (D-Ore.), Angus King (I-Maine), Jack Reed (D-R.I.), and Mazie K. Hirono (D-Hawaii). The proposed tax incentives are modeled on the current ITCs for solar energy and apply to either large, grid-connected energy storage systems or to smaller battery systems for residential power. Home battery storage, coupled with a small wind or roof-top solar system, could be used to store energy during the day for use later in the day or during overcast skies and to help consumers reduce their energy bills.

        Avista Receives Grant to Pilot a Shared Energy Economy Model

        Recently, Avista was awarded a grant from the Washington Department of Commerce and Governor Jay Inslee’s Clean Energy Fund 2 to demonstrate how a Shared Energy Economy can benefit Washington energy consumers. The grant is the latest example of Avista’s 127-year history of innovation and positions the utility for the energy future. Over the years, Avista has learned a lot about how to integrate intermittent renewable energy into the electrical grid from Avista’s Energy Storage Project in Pullman, which was funded by Avista with assistance from a grant from the Clean Energy Fund 1 in 2014.  Thanks to the grant from the Clean Energy Fund 2, Avista, with its partners, will build upon these learnings and take the next step by piloting a Shared Energy Economy model.

        One of the world’s largest downstream solar companies, Conergy, has started construction on what will likely be a world first ‘islanding’ solar and storage project in Australia’s north. The $42.5 million project is set to be developed in Lakeland, in far north Queensland, and will be the Southern Hemisphere’s first integrated solar, storage, and fringe-of-grid project of this size and scale — and will aim to be a world first demonstration of grid-to-islanding.

        A Texas Startup's Big Energy Idea: Storing Electricity Underground

        In a field in Central Texas, Aaron Mandell and his crew are running pumping equipment to bring a former oil and gas well back to life. But they’re not trying to extract black gold. Instead, they are developing a way to turn abandoned oil and gas wells into vaults for storing electricity. The concept behind Mandell’s startup, Quidnet Energy, sounds simple: pumping water deep into the earth to fill up the cracks in-between rocks that previously held fossil fuels. When the pressurized water is released, it acts like a spring as it races through a turbine-generator above ground, powering it to produce electricity.

        Power Efficiency Corp. won its bid to provide Con Edison 12 MW of demand response energy in the summer months of 2017 and 2018. The auction was part of the innovative Con Edison program to defer $1 billion in infrastructure expenditures required for Richmond Hill, Ridgewood, and Crown Heights networks in Brooklyn and Queens by reducing 52 MW of peak load in the BQDM area through a combination of customer sided solutions (41 MW) and non-traditional utility sided solutions (11 MW). Con Ed sought 41 MW in commitments for 2017 and 2018 from companies, with an objective to use these demand side resources to reduce peak summertime loads on the electric grid in this territory.

        Energy Storage for Public Health: A Smarter Way to Deploy Resources

        Energy storage deployment has been ramping up at a rapid pace across the country, mainly because it can reduce electric bills and cut utility expenses. It is now time to consider another key benefit of storage—public health, especially the power of energy storage to reduce pollution in marginalized communities. Researchers at the University of California Berkeley and PSE Health Energy, an energy research and policy institute, recently published an interesting article in the journal Energy Policy on the role of clean energy technologies and public health. It describes a new approach to the siting and dispatch of emerging clean energy resources, specifically energy storage and demand response. The authors argue that policy-driven clean energy deployment strategies should be locationally optimized—policymakers should think more about where these resources should go—based on impacts to air pollution, human health, and environmental justice.

        How Much Energy Storage Would Be Needed for California to Reach 50 Percent Solar?

        If California wants to continue increasing its share of solar power on the grid, it will need greater capacity to store it. The question remains: how much? A new study from the National Renewable Energy Laboratory attempts to quantify the answer. The authors model several scenarios in which the California grid generates 50 percent of its power from solar by 2030. To do so will require some pretty major changes, including more flexible baseload generation, as well as more deployment of electric vehicles, exports to other states and demand response.

        Grid-scale electricity storage will move closer to commercial reality on Friday when the U.K.’s grid operator offers contracts to companies to help balance the network, a key measure needed to help balance increasing supply from renewables. National Grid Plc will announce the winners of a bidding round for as much as 200 megawatts of storage capacity, which is about the size of a small power plant. It’s likely to be the storage industry’s biggest award this year in global market expected to install $5.1 billion of equipment in 2020, according to Bloomberg New Energy Finance. Storage plays a key role in the greening of utilities’ networks by allowing grid managers to handle higher volumes of intermittent power from the wind and sun.
