The UK capacity auctions, held in December last year, have drawn criticism from energy storage developers as a missed opportunity to support new storage technologies. The government secured 49.26 GW of capacity at a clearing price of £19.40/kW but despite initial promises many energy storage plants were unable to bid.
Energy storage is out competing backup gas power to provide peaking power in some markets within California. A total of 264 MW was selected by utility Southern California Edison (SCE) in recent tenders as strict air-pollution controls make gas peaking plants more expensive than batteries in some cases.
Nov 11 – After an increase of 2,734 Bcf during the April 1 to October 31 injection season, U.S. working natural gas in storage ended October at 3,571 billion cubic feet (Bcf), according to EIA figures.
"Higher gas production means that even if this winter were as cold as last year, EIA expects that natural gas storage at the end of March 2015 will be above its March 2014 level," analysts said.

Sept 8 – ABB and China's BYD have entered a strategic collaboration to develop new solutions for energy storage, used to backstop the fast ramp up of renewables with energy storage in off-grid and on-grid solutions.
ABB's products and technology for grid storage, electric vehicle charging and integrated marine systems, combined with BYD's knowledge in battery technology, "can broadly address worldwide energy storage requirements," the companies said.
Modelling from the Technical Research Centre of Finland (VTT) suggests that large scale power storage systems utilising gas may be a reality in the next 3 years. ”First prototypes for new products will be 12 months from now with industrial implementation in 24 to 26 months,” Pasi Vainikka, principal scientists at VTT told Gas to Power Journal.
New electrolysis stack technology from Canadian developer Hydrogenics offers a megawatt conversion capacity of 85%, paving the way for advanced gas power energy storage. "Creating a highly efficient link between the electrical grid and the natural gas system power to gas unlocks the massive energy storage capacity which we have already built and paid for," Daryl Wilson, chief executive at Hydrogenics told Gas to Power Journal.
UK-based research firm Highview Power Storage and GE Oil & Gas have announced a licencing and technology collaboration agreement to develop large-scale liquid air energy storage (LAES) systems. The technology is “ideally suited” for gas-fired peaker power plants, according to GE who struck the partnership to explore opportunities to improve operations of existing plants through the addition of energy storage.
Feb 19 – The German government has awarded €6.5 billion for E.ON's 5-megawatt energy storage project, named M5BAT (modular multi-megawatt multi-technology medium-voltage battery storage).
Works on the power storage will start in the autumn and E.ON said it expects the facility to start operation in 2015.
The project is a unique battery storage system, E.ON said and will focus on "renewables integration, testing of distributed regulating energy provision to promote grid stability, and power price arbitrage."
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.
