AI summary The text discusses the relationship between marginal generation costs and unit revenues, noting that marginal costs typically do not exceed unit revenues due to the inclusion of fixed costs. However, in 2022, marginal costs surged above average system fuel costs due to geopolitical events. The average system marginal cost increased by 14.7% from 2023 to 2024, primarily due to changes in the generation mix and increased load.

AI summary The document discusses the factors influencing the Short Run Marginal Cost (SRMC), particularly the role of electricity and gas, as well as environmental requirements. It also references a letter from the Board directing NS Power to make changes to the SRMC test based on recommendations from Multeese Consulting Inc.

AI summary The text discusses the marginal generation costs used by the Company in the SRMC test, which include only fuel and generation, operation, and maintenance costs, not fixed costs. It explains how the marginal cost relationship changed in 2022 due to geopolitical events and reverted in 2023. The average system marginal cost increased by 14.7% from 2023 to 2024 due to changes in the generation mix and increased load.

AI summary The document discusses how restructuring the electricity market could influence supply elasticity. It highlights that future supply elasticity depends on market structure, transmission constraints, and unbundling of ancillary services. Additionally, it mentions that hydro resources may be used more for spinning reserve rather than energy sales, affecting supply elasticity.
