Southern California Public Power Authority options solar tower

If completed, the EnviroMission 200MW Solar Tower power station would be the second  tallest man made structure in the world and a potential tourist attraction.

T5/4/11 The US power authority, Southern California Public Power Authority  (SCPPA) has taken a call option to purchase the first of two EnviroMission 200MW Solar Tower power stations planned for development in La Paz County, Arizona.
The SCPPA call option to purchase the first EnviroMission 200MW Solar Tower planned for development in Arizona’s northwest was a term of the 21 October 2010, SCPPA Power Purchase Agreement.
Details of the Power Purchase Agreement remained ‘commercial in confidence’ pending completion of the Power Sales Agreement negotiation with SCPPA member utilities intent on taking power allocations under the Power Purchase Agreement.
The ‘commercial in confidence’ PSA negotiation process has now been ratified between SCPPA and participating SCPPA member utilities, and two call options are now referenced at the SCPPA website:
SCPPA will have the right to purchase the first Solar Tower facility at La Paz at the ten or 30 year anniversary of operation at “Fair Market Value” or the ”amount of outstanding debt” whichever is greater at the time of execution of the option.
SCPPA has also taken a call option on a second Power Purchase Agreement to buy the power to be generated from a second 200MW La Paz Solar Tower development.
The second SCPPA option will provide SCPPA and its members the right to enter into a Power Purchase Agreement to purchase power from a second 200 MW Solar Tower at anytime during the first five years of the initial SCPPA agreement that would result in a 400MW Power Purchase Agreement.
SCPPA is a California joint power authority consisting of eleven municipal utilities and one irrigation district. SCPPA members deliver electricity to approximately two million metered accounts over 7,000 square miles to a population of nearly five million people.
EnviroMission Chief Executive, Roger Davey said “Solar Tower operation and maintenance modeling is projected to have a strong commercial advantage that will also be a first from a solar technology engineered to be predictable and not reliant on co-generation resources such as water or gas.”
“California has the most aggressive renewable energy mandate in the United States that requires Californian utilities and other electricity providers to generate 33% of their power from renewable energy sources by 2020.
“The unique characteristics of Solar Tower electricity generation were factors in the SCPPA Power Purchase Agreement decision for increased sustainable renewable energy generation in the SCPPA portfolio mix.”


  1. Twice the power and no dead birds? This looks like a better option than the SolarReserve proposal. If your going to have a big eye sore, at least this one will bring tourism and not suck up the ground water. Looks like the worlds largest sun dial to me!

  2. PUBLIC LANDS being taken up by something that the PUBLIC had very little awareness of. We've camped on BLM land for 2 years now. WHERE will we camp if they take up the land with all these solar towers? Some place other than Quartzsite.
