Of the 16,496 installations (excluding biomethane) that have received a payment up to the end of July 2017, 342 installations have been used for more than 12 hours a day. This is on average over each plants lifetime on the Non-domestic Renewable Heat Incentive (RHI). This has been assessed by looking at generation as a proportion of maximum capacity.
This analysis only covers installations that have submitted meter readings to Ofgem and we do not have the data to assess this for a given day. Biomethane is excluded from this analysis as it does not have a capacity from which operating hours could be assessed.
