Can a service provider claim cenvat credit on excise duty paid on electricity bill in service tax return? if yes, how?

I want to know weather a service provider can claim CENVAT tax Credit on excise duty paid on electricity bill or not. If yes, how? As the company is only providing services and not dealing in manufacture/produce of any kind of material. Can a organisation claim excise duty paid on electricity in service tax return likewise input tax credit on VAT or not. Please explain in detail.
