Flexibility of power network hinges on storing excess electricity and demand response to alleviate the impact of intermittent generation. California and Germany used subsidies as a trigger to advance power storage; yet to further commercialise these technologies the industry needs market-based regulation that remunerates flexibility and puts in place a level playing field between different assets.
Apr 28 – Energy arbitrage opportunities, renewable energy installations, and growing electric vehicles market are expected to drive the energy storage systems market to grow 4.4% annually. It is estimated to expand from $12.89 billion in 2015 to $15.96 Billion by 2020, according to MarketsandMarkets analysis.
Apr 15 – E.ON has started to sell its Aura electricity storage system in Germany. With a storage capacity of 4.4 kilowatt-hours, E.ON Aura can meet the entire electricity needs of a three- to four-person family during the evening and night hours. The system can increase a home’s energy self-sufficiency rate from about one third to around 70%.
Many are questioning if the century-old model of utilities selling kilowatt-hours still makes sense. At today's opening of PowerGen-Europe, Maria van der Hoeven, executive director of the IEA underlined that "the future lies in flexible backup capacity, decentralised generation and storage technologies."
Apr 30 – Tucson Electric Power has issued a request for proposals (RFP), seeking a project partner to build and own a 10 MW energy storage facility under a 10-year agreement. "We're looking for cost-effective, proven energy storage systems that will help us integrate renewable energy into our electric grid," TEP senior director Carmine Tilghman said, adding the company plans to slash its coal power capacity by 30% and step up the use of solar and gas generation.
Apr 30 - Australian power provider AusNet Services is implementing an ABB hybrid power storage, diesel generation and grid stabilisation system to enhance the management of peak electricity demand in the state of Victoria. At full power, the 1 MW pilot system will automatically provide additional power for the 22 kV distribution network during periods of peak demand.
AusNet Services provides gas and electricity to 1.3 million homes and businesses in Victoria – home to 5.8 million people.
Apr 17 – In California's central valley, Con Edison Development (CED) will install an 8 MWh battery energy storage, able to provide 2 MW of electricity over a four hour period. The GE storage solution will be utilising Mark VIe-based plant control, Brilliance MW Inverters, and packaged lithium ion batteries.
