In a recent development, the Federal Energy Regulatory Commission (FERC) has accepted a proposal from ISO New England Inc. (“ISO-NE”) to permit electric storage facilities to be planned and operated as transmission-only assets (“SATOAs”). This decision was made to primarily address system needs identified during the regional system planning process.
FERC’s ruling acknowledges the growing significance of energy storage in the power grid of the future. ISO-NE’s proposal aims to provide a fair and reasonable framework for electric storage resources to be acknowledged as transmission assets for regional planning purposes. This classification will make these assets eligible for cost-based rate recovery.
The proposal marks a strategic shift in the role of electric storage facilities in the power grid. It represents an important modification of the traditional understanding of these facilities, which have often been considered either generation or load resources rather than transmission assets.
Recognizing electric storage resources as SATOAs can open up a whole new dimension in electricity transmission and grid reliability. It accommodates the unique capabilities of electric storage facilities and aligns them with the current and future transmission needs of the grid.
With this adoption of the ISO-NE proposal, the industry could witness an evolution of planning models, which can better reflect the potential benefits and costs associated with electric storage. Furthermore, energy storage facilities could now have a significant influence in guiding investments for future transmission projects.
This regulatory update matters greatly to professionals in the energy and legal sectors for its implications on the legal structuring and contractual considerations surrounding these assets. Keeping informed about these changes will be essential for effective decision-making.
