Solar Power For a Wastewater Plant

In Coshocton, population almost 36,000, officials are getting ready to cast their vote for a local solar company so small it doesn’t even have its own web page.

Called Solar Vision LLC, the Westerville-based company, which recently appointed Tom van Cleef as managing director and vice president, has offered to provide the city with a 355-kilowatt system, which would generate about 1,155 kilowatt hours per day, or enough to run a large, American home.

The solar array would be set up in an area behind the wastewater plant, on South Second Street, to provide about 45 percent of the plant’s needs on a 20-year power purchase agreement (PPA) that would deliver the electricity for 15 percent less than the water utility currently pays regional utility American Electric Power, or AEP.

Solar Vision LLC’s account manager, Jamie Albert, could not give exact savings figures for the solar installation, since AEP’s rates and fees vary throughout the year, depending on the type of power purchased, peak demand rates, and service charges allocated by the utility based on use, but Albert estimated that the solar array would save the city about $4,100 annually.

The other 55 percent of electricity needed by the water utility would continue to be provided by AEP, one of the nation’s largest utilities (at five million customers across 11 states) whose generation mix is 68 percent coal, 23 percent natural gas, 6 percent nuclear, two percent power pumped from storage (from excess generation) and less than 1 percent renewables like hydro and wind.

AEP, which justly earned its reputation in 2000 as the head of the “Dirty Dozen” – a consortium of 12 power companies sued by the U.S. Environmental Protection Agency and the U.S. Dept. of Justice for Clean Air Act violations – led the list by virtue of its five polluting coal-fired generation plants (the term “Dirty Dozen” has since been expunged from the record). AEP owns and operates about 80 power plants and the largest transmission system in the country.

Once Coshocton’s solar array is paid for, in terms of the PPA, it can buy the array outright or stay with Solar Vision at a 30-percent discount and a portion of the renewable energy credits, or RECs.

Coshocton’s bill for the water treatment plant is currently about $4,500 per month. The cost of installing the solar array, estimated at about $2 million, would be absorbed by Solar Vision LLC in exchange for the federal tax credit, RECs, and power sold through the array.

Solar Vision LLC, which has already raised $10 million in venture capital (for this and other projects), would maintain the system at its own expense. The installation is expected to take five days and, based on Ohio solar irradiance studies already performed by Solar Vision LLC – which show values the same as Germany’s, the country with the most solar installations in the world – the system should provide at least 45 percent of needed electricity.

The Solar Project

$58.94

High Quality Content by WIKIPEDIA articles In 1995 Solar One was converted into Solar Two, by adding a second ring of 108 larger 95 m (1,000 ft ) heliostats around the existing Solar One, totaling 1926 heliostats with a total area of 82,750 m (891,000 ft ). This gave Solar Two the ability to produce 10 megawatts. Solar Two used molten salt, a combination of 60 sodium nitrate and 40 potassium nitrate, as an energy storage medium instead of oil or water as with Solar One. This helped in energy storage during brief interruptions in sunlight due to clouds. The molten salt also allowed the energy to be stored in large tanks for future use such as night time.Solar Two proved it could run continuously around the clock producing power. Solar Two was decommissioned in 1999, and was converted by the University of California, Davis, into an Air Cherenkov Telescope in 2001, measuring gamma rays hitting the atmosphere. Its name is now C.A.C.T.U.S.. Solar Twos 3 primary participants were Southern California Edison (SCE), the Los Angeles Department of Water and Power (LADWP), and the U.S. Department of Energy (DOE).

Solar Tres Power Tower

$68.51

High Quality Content by WIKIPEDIA articles Solar Tres is a planned 15 MW power plant based on solar thermal energy. It is located west of the city of cija, in Andalusia, Spain. Solar Tres is based on the solar power tower concepts pioneered in the U.S.s Solar One and Solar Two demonstration projects. Solar Tres uses a molten salt as its working fluid, allowing it to be stored in the molten state for power generation at any time. The project, which has received a subsidy of five million Euro from the European Commission, makes use of the Solar Two technology tested in Barstow, California, but will be approximately three times the size. Solar Tres will make use of several advances in technology since Solar Two was designed and built. Author: Surhone, Lambert M./ Timpledon, Miriam T./ Marseken, Susan F.

Topaz Solar Farm

$60.54

High Quality Content by WIKIPEDIA articles Topaz Solar Farm is a proposed 550 megawat solar photovoltaic power plant, to be built by First Solar, Inc. in the Carrizo Plain, northwest of California Valley at a cost of over 1 billion. On August 14, 2008, Pacific Gas and Electric announced an agreement to buy all the power from the power plant. Commenting on this project and a nearby 250 MW project announced at the same time, Daniel Kammen, the director of the Renewable and Appropriate Energy Laboratory at University of California, Berkeley, said This scale is ten times larger than what was being talked about awhile ago. OptiSolar, the instigator of the project, had bought 9.5 square miles of ranchland, In November 2009, First Solar announced that it had purchased options to an additional 640 acres from Ausras canceled Carrizo Energy Solar Farm. First Solar would reconfigure the project to minimize the use of land covered by the Williamson Act. Author: Surhone, Lambert M./ Timpledon, Miriam T./ Marseken, Susan F.
