Market Index Data is used in Settlement to calculate the reverse price(84Kb) for each Settlement Period which reflects the price of wholesale electricity in Great Britain in the short-term market.
Market Index Data comprises a volume in MWh and a price of £/MWh, which are determined in accordance with the Market Index Definition Statement (MIDS)(142Kb) (MIDS).
The MIDS sets out the MID parameters which include specific trades into the Market Index Volume and an Individual Liquidity Threshold (ILT) for which minimum volume of trades must have been made for the calculation of the Market Index Price to take place.
The Market Index Price is used in the Energy Imbalance Price calculations as the ‘reverse’ price when the volume of trades on the Power Exchange is greater than the agreed ILT, if the volume is below the ILT the price will be defaulted according to the default price(84Kb) options.
