Wind Offer Arrangement (WOA) Project

This programme of work was completed  October 2019

What’s WOA?

The objective of this project is to enable intermittent generators (wind farm owners) to withdraw their generation in an efficient, centrally coordinated way when the spot market price is below their short-run marginal cost (SRMC).
