Energy Update: Implementation Roadmap For Hybrid Co-Located Sites With MEC Sharing

System operators EirGrid and ESB Networks (the “SOs”) published the Implementation Roadmap for Hybrid Co-Located sites with Maximum Export Capacity (“MEC”) sharing. The roadmap follows the decision of the Commission for Regulation of Utilities (“CRU“) in April 2026, which we considered here: Energy Update: Sharing Maximum Export Capacity at electricity grid connection points.

Scope / Assumptions

The SOs note that the CRU decision addressed only Hybrid Co-Located projects, which the CRU defined as projects that combine multiple forms of generation and/or storage technologies behind a single defined connection point to the electricity distribution or transmission network where the generation units for the different technologies are individually sub-metered and registered, and operate independently of one another for market, settlement, and dispatch purposes.
