IESO 50MW Grid Energy Storage Procurement - Phase 1 (2014)
The Phase I Grid Energy Storage procurement was designed to specifically investigate the capabilities of energy storage facilities, featuring diverse technologies, to offer either or both of the following reliability services: regulation, and reactive support and voltage control (RSVC). The procurement also required that the projects be located across different electrical zones in Ontario to evaluate their effectiveness at alleviating local constraints or restrictions. Additionally, successful projects could be dispatched to explore additional bulk electricity services such as energy shifting, providing ramping support and SBG management. '
Phase I received a significant amount of interest both within Ontario, nationally and internationally. Over 400 proposals were submitted in response to the Request for Proposal (RFP). The successful proposals included the following technologies:
- Thermal energy storage;
- Stationary batteries;
- Flywheels; and
- Power-to-gas (hydrogen storage).
In Phase I of the Grid Energy Storage procurement, the IESO selected 3 energy storage technologies for a total of 33.54 MW from five companies.
