Thermal energy storage such as that being commercialised by Ice Energy may have a much greater impact than just doing away with the duck curve.
If sold at scale, it could also effectively put traditional air conditioning (AC) out of business in large areas of the world where AC is essential for daytime workplace and home cooling.
Ice Energy is already bracing itself for growing demand in sunny US territories where increasing distributed solar penetration is causing regulators to move away from net metering plans.
In places such as Hawaii, the shift away from net metering is depriving solar-equipped homeowners of electricity bill reductions and forcing them to look at alternative ways to save money with PV. Powering AC units is one option.
AC is one of the biggest daytime and evening energy loads of households in hot locations. With net metering, much of electricity you need to drive AC units can come for free from any excess you have poured into the grid. Read more →

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 Reportlast year, and follows growing utility interest in using Ice Bears for demand response. Read more →
