Thermal energy storage developer Ice Energy is gearing up to increase sales of a product that has the potential to end California’s famous ‘duck curve’.

The Southern California Public Power Authority (SCPPA) has already announced plans to buy up to 100 of Ice Energy’s Ice Bear 20 residential cooling systems, which completed testing about a month ago.

The 20 ton-hour systems use energy when there is excess production, for example at night, to create ice that is then used for cooling during peak electricity consumption periods, such as evenings.

“At 9.6kW per Ice Bear 20, the order will potentially add nearly 1MW of new energy storage and peak demand reduction capacity to the SCPPA network, saving energy, improving efficiency and reducing emissions,” said Ice Energy.

The deal marks Ice Energy’s debut in the residential energy storage market, a move the company unveiled in Energy Storage Report last year, and follows growing utility interest in using Ice Bears for demand response.

A UK energy storage system developer is looking to go from 650 installations today to 1m by 2020 with an aggregation-based residential business model.

London-based Moixa Energy Holdings is positioning itself as a utility’s friend by aggregating residential storage assets into a virtual power plant that provides ancillary grid services, then sharing the rewards with its customer base.

On its website, the company claims its GridShare service can earn homeowners between GBP£50 and £75 a year, or “almost 15% of the average electricity bill.”

Chief executive Simon Daniel told Energy Storage Report that 2016 was a scaling-up year for Moixa, which began piloting smart battery technology in 2012 and launched its current products two years ago.

The company is expecting to shift up to 100,000 storage systems within the next 36 months, Daniel said. And although Moixa is looking to bolster sales abroad, most of that capacity could go online in the UK.
