Renovalia and Infinia partner to build solar dish-stirling power plants

August 8, 2009

The Spanish renewable energy company Renovalia has signed an exclusive frameworks agreement for a  joint venture with the American firm Infinia to build thermosolar plants for third parties in Spain and Italy, and to develop projects in the rest of southern Europe, North Africa and other countries.

In addition, Renovalia will provide some components for the solar system to be manufactured in Spain by subsidiaries of the Group and external suppliers.

According to Renovalia, this is the first time that NASA technology will be used in Spain to produce electricity. To accomplish this, the Spanish-American partnership is setting up a €400 million ($567 million), 71 MW power plant in Villarobledo, Castile-La Mancha.

In addition to the Villarobledo plant, Renovalia is planning to install 150 MW a year in the future, using this technology which, in the area of renewable energy, is the least developed.

Infinia’s Solar System relies on a Free-Piston Stirling Engine (FPSE) to convert concentrated solar heat to electricity. Infinia FPSEs convert thermal energy from external energy sources to linear motion which drives an integral linear alternator, thus generating clean, reliable electricity. 

This system is characterized by nearly 24% efficiency, low maintenance and operating autonomy. The main difference compared to other thermal technologies is that it does not need water or gas to produce electricity. Moreover, the engines are quiet, do not require lubrication and can be connected to the network in modular phases. A 50 MW plant using this technology can be built in less than a year.

The facility operates during sunlight hours and remains out of service during night hours. That is why the department of R+D of  Renovalia together with a team of international consultants and Infinia are working to develop a energy storage system to complement this technology.

GA-Solar and Sierra Nevada Corporation Form Renewable Energy JV for projects in Nevada and Southwest US

August 6, 2009

Sierra Nevada Corporation President, Eren Ozmen, announces today the formation of a new joint venture between SNC and GA-Solar North America. GA-SNC Solar LLC is dedicated to creating solar renewable energy in Nevada and surrounding states. Through this joint venture, GA-SNC Solar will design, build and install photovoltaic solar generation facilities that generate energy for its customers.

GA-SNC Solar is working with local Nevada contractors on the first Nevada based project which is expected to begin later this summer. The company is pursuing future PV solar projects for the federal government, state governments, municipalities, military, tribal organizations, utilities and companies that are large consumers of electricity.

This is Sierra Nevada Corporation’s first entry in renewable energy. Sierra Nevada brings the experience of developing and producing large products and programs, while its partner GA-Solar, is one of the largest and most experienced providers of solar power in the world. Both companies are privately owned and operated by families with similar company cultures and viewpoints about developing renewable energy.

“Renewable energy and energy efficiency have steadily gained popularity in Nevada,” said Greg Cox, Corporate Vice President, Sierra Nevada Corporation. “GA-Solar is a leader in photovoltaic solar generation and is a great partner with the depth and breadth of experience needed to help us enter into this growing energy sector.”

“The renewable market is growing because both federal and state governments are beginning to incentivize the development of renewable power generation and mandate the percentage of energy production that must be produced, said Greg Cox. “The U.S. renewable market is the largest in the world and we are fortunate to be in a region that has the necessary abundance of sun, wind and geothermal activity for the production of renewable energy.”

According to the Department of Energy, Nevada currently ranks second in the Nation for development and use of its geothermal resources and has considerable hydroelectric capacity. In addition, the state recently changed its Renewable Portfolio Standard (RPS) increasing the percentage of renewable energy generation required each year through 2025. The GA-SNC Solar partnership Sierra Nevada and GA-Solar will build photovoltaic facilities — the world’s fastest growing energy technology — to convert sunlight directly into electricity. With the increased need for clean energy sources and open space, Nevada is a prime location for photovoltaic solar generation facilities.
