Ofgem to investigate Drax compliance with biomass reporting rules

Regulator expected to examine whether sustainability reports on sourcing of wood pellets meet renewables subsidy criteria

Drax is facing an investigation by the energy regulator into the sustainability of the biomass it uses at its wood-burning power plant amid growing scepticism over its green credentials.

The energy regulator, Ofgem, said it would investigate whether the owner of Britain's biggest power plant, in North Yorkshire, was in breach of the reporting rules required for its renewable energy subsidy scheme.
