Southern California Public Power Authority (SCPPA) has approved a power purchase agreement (PPA) with EnviroMission to purchase green power from EnviroMission's Solar Tower power station development planned for Arizona.

Solar Tower technology uses solar radiation to heat air to drive turbines to generate clean green electricity.

Renewable energy to be sold under the PPA will provide SCPPA with a green alternative competitive with fossil fuel generators once the expected cost of mitigating greenhouse gas emissions is also included, EnviroMission said.

EnviroMission chief executive Roger Davey said that finalization of this PPA with SCPPA will allow project finance to be secured for Solar Tower power station development and the front end engineering and design (FEED) necessary to break ground at the earmarked Arizona site to commence.

EnviroMission is a developer of Solar Tower renewable energy technology on a global scale.
