Solar energy companies around the world, like Solar City USA, have been providing affordable, renewable electricity to homes and businesses across the US and Mexico through the use of a Power Purchase Agreement (PPA). Other countries, such as Germany, have also used similar systems for years. At COREnergy, we offer similar plans to small and medium businesses in Australia who want to be in control of their power bills. We call this plan an Evergreen Energy Plan, or EEP.
