For a business on the shared electricity grid, switching to a green tariff changes what you buy from the supplier and the renewable generation evidence it provides. Your local network still delivers the electricity, and your site’s resilience still depends on the network and any backup supply you have.

Check procurement and resilience separately

• For procurement, compare prices, contract terms, certificate coverage and any commitments to purchase from specific generators.
• For resilience, identify critical loads and discuss continuity or backup power requirements with your network operator and a qualified adviser.
