During monthly checks carried out on the PPA statements by the Asset Management team, multiple seasonal pricing errors were detected.
These often occurred on the borders of where the pricing changed between seasons. For one project, the total value of the error during one season change cycle was over £1.3K.
Although not significant on its own, the error was picked up on multiple projects across PPA providers, so when calculated over the lifetime of the portfolio the sum becomes significant – a figure in the region of £25K.
