Energy storage systems provide a range of services to generate revenue, create savings, and improve electricity resiliency.
He coined the term 'iEnergy' to propagate an annual/monthly subscription fee for energy, rather than the present-day commodity-led pay per kilowatt of electricity system.
[1] Foster believes a service-led system would put the onus on the energy supplier to improve reliability and offer the best possible service to customers.
The most common energy storage systems used for ESaaS are lithium-ion[10] or flow[11] batteries due to their compact size, non-invasive installation, high efficiencies, and fast reaction times but other storage mediums may be used such as compressed air,[12] flywheels,[13] or pumped hydro.
[30] Current early adopters of ESaaS are manufacturers (chemical, electrical, lighting, metal, petrochemical, plastics), commercial (retail, large offices, medium offices, multi-residential, supermarkets), public facilities (colleges, universities, hotels, hospitality, schools), and resources (oil & extraction, pulp & paper, metals & ore, food processing, greenhouses).
The load shifting capability provided by ESaaS displaces heavy emitting generation requirements.
