Aug 25 – Southern California Edison has selected a subsidiary of AltaGas to build a 20 MW storage project with a discharge capacity of 80 MWh east of Los Angeles. AltaGas Pomona Energy Storage will build, own and operate the project, which is estimated to cost up to $45 million and is meant to be operational by December. State regulators urge utilities to procure storage to avoid power outages.
Aug 25 – More than 20 days after Malta’s Prime Minister Joseph Muscat attended the ‘Sail-away Ceremony’, the gas storage ship destined to support power stations in Malta is still docked in Singapore. No fixed date has been set for its departure – so it is unclear whether will reach Malta as planned in mid-September.
Affordable storage is seen as the missing link between intermittent renewable power and reliable energy supply. McKinsey research anticipates costs could fall to $200 per kWh in 2020 – half of today’s price, which would help transform the energy mix of many nations. By 2025, costs of power storage are expected to fall to $160 kWh or less, making it affordable to use for utilities and grid operators.
China National Petroleum Corporation (CNPC) and Russia’s Gazprom have agreed to form a joint venture for gas-fired power generation and underground gas storage in China. The MoU was signed on Saturday after detailed discussions on Russian gas supplies via the western route – the so-called ‘Power of Siberia’ pipeline is already under construction.
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.
