Dong Energy, RWE, Vattenfall, SSE, Scottish Renewables, EDF Energy, E.on, and Centrica have formed the group to highlight areas within O&M, which could be improved to drive down costs.
The forum has already met once and identified two common areas with high O&M costs: blade erosion and cable damage.
Development body ORE Catapult hopes that with discussion of ideas and best practice, the companies will be able to achieve the government target of producing electricity for £100/MWh.
The forum follows other efforts in the UK industry to make savings. In January, the ORE Catapult and the Crown Estate, which is responsible for the waters around the UK, launched a data-sharing programme called Sparta, aimed at improving wind turbine performance and reliability.
Narec and ORE Catapult merged in April to form a singular development body in the UK.
