For standalone energy storage contracts, these are typically structured with a fixed monthly capacity payment plus some variable cost per megawatt hour (MWh) of throughput. For a combined renewables-plus-storage project, it may be structured with an energy-only price in lieu of a fixed monthly capacity payment.
Once completed, it is expected to be able to supply 10 hours of electricity to approximately 18,000 households. In addition to the above two companies, several startups are advancing the development of energy storage technologies that use gases or liquids such as air and water as storage media.
Some PPAs for new energy storage resources have been structured as capacity-only contracts in which the developer is responsible for the sale of energy and all costs associated therewith—including the costs of the required energy procured from the utility.
