BSC Insight: Increasing costs for balancing the GB System

The Electricity System Operator (ESO) plays an essential role in balancing supply and demand using the Balancing Mechanism (BM). Matching supply and demand requires payments to be made between the ESO and participating consumers and generators. Consumers and generators submit prices for volumes of energy they can provide within a half-hour period (Settlement Period) to balance the system. In this Insight article, analyst Angus Fairbairn looks at balancing costs of ESO since 2015.

BSC Insight: Why the Reserve Scarcity Price is being reviewed

National Grid ESO raised BSC Issue Group 92 to review the Reserve Scarcity Price with representatives from across the electricity industry. The need for this arose due to feedback from industry representatives that the Reserve Scarcity Price has had less of an impact on System Prices than expected and a need to ensure the calculation is fit for a future energy market.

The issue group will consist of a series of workgroups facilitated by Elexon. In this Insight article our Analysis and Insight Delivery Lead, Emma Tribe, explains how the Reserve Scarcity Price is calculated, how it is included in the System Price Calculation and how it has affected System Prices since its introduction in 2015.

The 2010s were a period of significant change for both Elexon and the wider industry. The shifts seen during the span of ten years were both unprecedented and unpredicted.
