Grid Services Guide
-
The Grid Services Guide provides a structured reference for navigating the markets that determine battery storage revenue across Northwest Europe. Drawing on TenneT, ENTSO-E, EPEX SPOT, GOPACS, and the EU Network Codes (EB-GL, SO-GL, RfG), the guide documents the three main grid service categories balancing, trading, and congestion management and sets each market side-by-side with its technical requirements, revenue mechanics, and access models, showing where opportunities lie, where the constraints bind, and what the differences mean for asset economics.
Rather than treating grid services as a single revenue stream, the guide anchors each market in its commercial consequence: the wrong product choice can mean the wrong technical requirements, the wrong revenue assumption, and the wrong investment case.
Market scoping – Determine which products fit your asset: FCR, aFRR, mFRR, day-ahead, intraday, or congestion management.
Technical requirements – Detailed specifications for prequalification, telemetry, response times, and minimum bid sizes across all balancing products.
Market access models – Compare direct BSP, aggregator, and supplier pass-through routes, with practical guidance on which fits which asset profile.
FAQ and definitions – Resolve common ambiguities with authoritative source citations from TenneT, ENTSO-E, and the EU Network Codes.
