Regulerkraft (balancing power) is the collective term for the capacity services that StatnettNorway's system operator for the transmission grid - owns and operates the high-voltage network and operates Elhub. uses to balance production and consumption in the power systemThe totality of facilities, lines and systems for producing, transmitting and distributing electrical energy. second by second. The power system requires that supply and demand are in constant balance - deviations cause frequency fluctuations. Statnett procures balancing power in three markets: FCR (Frequency Containment Reserve) for immediate frequency response (seconds), aFRR (automatic Frequency Restoration Reserve) for automatic restoration (minutes), and mFRR (manual Frequency Restoration Reserve) for manual regulation (quarter-hours and hours). Providers of balancing power can be power producers, industrial consumers with flexible consumption, and aggregators. Delivering balancing power requires fast response, reliable communication, and accurate metering - and is a growing market as more solar and wind power reduces the system's inertia.
