Dual-ministry energy storage

Is energy storage a dual-use asset?

3.0 Energy Storage as a Dual-Use Asset Because the U.S. electric grid was built before electrical energy storage technologies were widely available, it had to be designed and built as a real-time delivery system that is large enough to meet the highest demand, even if that demand only occurs for a few hours per year.

Is dual-use energy storage a transmission-only asset?

After public comments elucidated the numerous challenges associated with enabling dual-use storage, MISO staff proposed to focus the proceeding on identifying the measures necessary to enable storage as a transmission-only asset (SATOA), and revisit the question of dual-use energy storage in a subsequent future phase.

Should FERC consider dual-use energy storage?

Allowing an asset owner to recover their full investment through cost-based transmission rates and then additional revenue in the market would not accomplish that goal, so FERC indicated that dual-use energy storage mechanisms would need to balance the two revenue streams to ensure that customers do not overpay for the asset. 2.

Should pumped storage hydropower (PSH) facilities have a dual-use facility?

Implementation of the policy statement creates a significant opportunity for pumped storage hydropower (PSH) facilities in particular, given that their scale is well aligned with transmission applications and that a proposed dual-use PSH facility was a key motivating factor for the policy statement.

Do direct transmission planners need to consider energy storage alternatives?

Orders 890 and 1000 direct transmission planners to consider energy storage and other non-transmission alternatives, but only at the request of stakeholders. While the orders require planners to indicate how and when stakeholders may make those requests, most regions do not appear to have developed that guidance.
