Approval rate is over decided applications only (approved ÷ approved+refused); withdrawn and undecided schemes are excluded. A permission later expired still counts as approved because consent was granted. REPD covers schemes of roughly 150 kW and above, is published quarterly, and does not record refusal reasons — so nothing here explains why a scheme was refused.
