Energy_Imbalance_£m

Title Energy Imbalance
Type integer
Description Energy imbalance is the difference between the amount of energy generated in real time, the amount of energy consumed during that same time, and the amount of energy sold ahead of the generation time for that specific time period. The monthly energy imbalance cost can be negative or positive depending whether the market was predominantly long or short.
Comment Energy Imbalance can be either positive or negative

Positive_Reserve_£m

Title Positive Reserve
Type number
Description Positive reserve is required to operate the transmission system securely and provides the reserve energy required to meet the demand when there are shortfalls, due to demand changes or generation breakdowns.

Negative_Reserve_£m

Title Negative Reserve
Type number
Description A Negative Reserve service can provide the flexibility to reduce generation or increase demand to ensure supply and demand are balanced. The service is held in reserve to cover unforeseen fluctuations in demand, or generation from demand side PV and wind.

Frequency_Control_£m

Title Frequency Control
Type number
Description This is the sum of the Fast reserve and the Response costs. Fast Reserve provides the rapid and reliable delivery of active power through an increased output from generation or a reduction in consumption from demand sources, following receipt of an electronic dispatch instruction from National Grid. Fast Reserve service must commence within two minutes following instruction, at rates of 25MW or greater per minute and providing a minimum of 50MW. Response is a service we use to keep the system frequency close to 50Hz. Fast acting generation and demand services are held in readiness to manage any fluctuation in the system frequency, which could be caused by a sudden loss of generation or demand. There are three types of frequency response known as “primary”, “secondary” and “high”. The difference between primary and secondary is the speed at which they act recover the system frequency. Both primary and secondary react to low frequency conditions, and high response.

Other_£m

Title Other
Type number
Description This includes minor components which are any actions that don’t meet the defined rules to categorise costs. This also includes costs any costs required to manage voltage. We manage voltage levels across the grid to make sure we stay within our operational standards and avoid damage to transmission equipment. Voltage levels are controlled by reactive power, and we pay providers to help manage voltage levels on the system by controlling the volume of reactive power that they absorb or generate.
