There is, however, the potential for trends to change as renewables penetration on the grid continues to grow. The UK's National Grid has revealed the de-rating factors for solar and wind energy for participation in the Capacity Market and the proposed methodologies. Greater levels of data regarding “long run average contribution” of weather resources enabled the National Grid to update its notional power curves for onshore and offshore wind for the first time in several years. In a press release today, the grid said that it had updated its forecast for future generation capacity from renewable sources based on new information provided by the UK Renewable Energy Agency (UKREA). However, a paucity of data for solar saw it given a de-rating of 1% to 2%, boosted from "almost negligible" by the use of storage technology.
