A power purchase agreement (PPA), or electricity power agreement, is a long-term contract between an electricity generator and a customer, usually a utility, government or company. PPAs may last anywhere between 5 and 20 years, during which time the power purchaser buys energy at a pre-negotiated price.

Ice storage air conditioning is a form of thermal energy storage in which cooling capacity is stored by freezing water and recovered later by melting the ice. In building applications, the storage can be charged when cooling demand or electricity prices are lower and discharged during periods of higher cooling demand,…
