We have two tariffs available:


This is a deep green source tariff that matches 100% of the electricity that you use with a supply from renewable power. We support a number of technologies, energy from waste, small scale hydro, solar, organic waste gasification, pig waste, vegetable oil and wind to name a few.

All this power qualifies for Renewable Obligation Certificates (ROCS) under the Renewables Obligation.
