Introduction to Energy Storage Project Development

Often they will request the right to add storage, and the offtaker will typically receive an option to enter into an offtake agreement concerning such added storage. The next major contract needed to successfully develop an energy storage project is an engineering, procurement, and construction (EPC) contract.

The goal of the DOE Energy Storage Program is to develop advanced energy storage technologies and systems in collaboration with industry, academia, and government institutions that will increase the reliability, performance, and sustainability of electricity generation and transmission in the electric grid and in standalone systems.

From the perspective of energy storage, project economics may be significantly impacted by the integration of ESS into the project. ESS benefits the project by extending the generation capacity of the mini-grid and contributes to the stability and optimisation of an isolated system.

In the case of a stand-alone energy storage system, the project company can charge from the network at a time to be agreed upon with the system operator. Behind-the-meter energy storage systems will generally be treated like any other electricity consumer.

The development of thermal, mechanical, and chemical energy storage technologies addresses challenges created by significant penetration of variable renewable energy sources into the electricity mix.

The earliest grid-scale energy storage technology is pumped hydroelectric storage, introduced to the grid in the 1930s. Significant capacity growth has continued since, and pumped hydro is still the dominant technology in energy storage on a capacity basis.
