A 500 kilowatt-hour peak load shifting unit is to be installed at the Discovery Science Center in Southern California by GE as part of efforts to reduce peak demand on the grid. The GE storage and Princeton Power Systems (PPS) inverter control system is expected to shift 10-20% of daily electrical load to off-peak time periods, freeing up peakload power supply for other users.
The California Public Utilities Commission (PUC) has voted in legislation to mandate 1,325 megawatts of energy storage in the state in a move set fast-track expansion of the power-to-gas sector. The PUC vote mandates Pacific Gas and Electric Company, Southern California Edison, and San Diego Gas & Electric to install extra storage capacity by 2020.
Oct 1 - The Spanish government has halted work on the Castor offshore submarine gas storage plant following more than 200 minor earthquakes nearby, off the eastern coast of Valencia.
The Castor facility is one of the country's biggest investments in gas infrastructure and is meant to cover 30 percent of Spain's daily gas consumption. It was the first European project to issue so-called "project bonds".
SoCalGas, a gas grid operator in California, is spending £1 million on the cleantech fund LA Cleantech Incubator (LACI) to develop 'renewable natural gas.' "Biogas is one source but, in the future, we expect other pathways such as 'water splitting' through solar chemical conversion and hydrogen electrolysis to provide renewable natural gas," said Jeff Reed, SoCalGas director of business strategy and development.
Italian marine classification society RINA has approved a design for a compressed natural gas (CNG) storage system aboard vessles, which is being used as gas feed at a fuel oil peaking power plant retrofitted to run on gas in Grati, Indonesia. The 300MW unit is "the world's largest CNG storage system," according to RINA.
July 30 - Samsung Electronics Co and S&C Electric Co have joined forces to develop an energy storage project that could save Britain up to £300 million annually once 2 GW of storage is installed by 2020.
The project comes at a cost of £28.5 million and will be capable of storing up to 10 MW-hours of electricity.
As part of a 'smart grid' feasibility study, energy storage company ITM Power has launched an upgrade to its hydrogen-producing HGas electrolyser on the Isle of Wight, UK to allow more solar and wind power to come on the grid safely. Sponsored by the UK government, the study examines how HGas electrolyser units produce hydrogen gas from surplus renewable power that utilities can sell as fuel to natural gas consumers and power plants.
In an effort to curb energy bills, Japan's Ministry of Economy, Trade and Industry is using Kitakyushu City as a test bed for a hydrogen storage system integrated with controller software, solar panels and industrial CHP (Combined Heat and Power) backup. The City of Yokohama, Toyota City, and Keihanna are also part of the Japan Smart City Portal experiment, which began in 2010 and ends in 2014.
Electricity storage technologies, operating on hourly or daily timescales, tend to be deployed to take advantage of variations in the price of electricity. Researchers at the US Energy Information Administration point out that energy storage increases security of power supply as it flattens the daily load shape and integrating variable generation like wind.
May 28 - Pacific Gas and Electric Company (PG&E) and the California Energy Commission have launched a battery energy storage system pilot project in east San Jose to better balance power needs of the electric grid.
The project launch was made possible following a $3.3 million grant from the Energy Commission to PG&E that will help fund the installation and evaluation of the system.
Jan 25 - Duke Energy Renewables, part of Duke Energy's Commercial Businesses announced the completion of North America's largest battery storage project at its Notrees Windpower Project in west Texas.
The 36 MW energy storage and power management system completed testing and commenced operations in December.
Sept 21 - Going into the winter withdrawal season, gas storage volumes in the UK are on healthy levels on soft European demand for UK gas through the Interconnector, Deutsche Bank analysts said today.
Month-to-date Interconnector flows have averaged 9mcm/d this year versus 52mcm/d last year in early September (excluding the maintenance period), the bank said in a weekly commodity report.
Volumes in the UK are nearly equal to that seen last year, even with the large withdrawal in September, compared with a net injection last September into medium-range storage.
