Formation of the Concentrating Solar Power Alliance (CSPA)

Tex Wilkins, Veteran of U.S. Department of Energy Solar Program, to Lead New Organization. Torresol Energy, a leading company that promotes the technological development, construction, operation and maintenance of large concentrated solar power plants, has announced today along with Abengoa and BrightSource Energy, the formation of the Concentrating Solar Power Alliance (CSPA). The new organization is dedicated to educating U.S. regulators, utilities and grid operators about the unique benefits of concentrating solar power (CSP) and of thermal energy storage as a foundational resource for a reliable, low-carbon electricity mix and a driver of economic growth.

“Concentrating solar power technology is the only renewable resource that is capable of harnessing the world’s most abundant fuel source – the sun – to produce reliable, cost-effective, and dispatchable electricity,” said Tex Wilkins, Executive Director of CSP Alliance. “We believe CSP, with the ability to dispatch electricity when it is needed is critical in meeting the energy challenges facing the United States and the world.”

Felicia Bellows, Senior Vice President of Development at Torresol Energy in the U.S., declared: “With this new alliance we expect to promote solar thermal energy as a sustainable source of power and therefore contribute to the protection of the environment for the future generations.”

“From Torresol Energy, we keep working in order to reduce the costs of this clean energy, in order to make it an economically competitive option to traditional sources.” – Ms. Bellows added – “We are working in new innovations, such as a single-tank storage system or a new generation of high power central tower plants with molten salt receiver technology. We are definitely following the path established last year with the commercial operation of the innovative plant Gemasolar, the first commercial plant in the world with a central tower molten salt receiver.”

The Alliance’s mission is to promote the increased acceptance, adoption and implementation of concentrating solar power plants in the United States. The Alliance will also promote policies to encourage and advance CSP technology deployment.

CSP technologies use mirrors to concentrate the thermal energy of the sun to drive a conventional steam turbine. The first commercial CSP plants were built in California in the mid-1980’s and are operating today with a higher output than when they were new. There are currently over 500 MW of CSP plants operating in the U.S and more than 1,300 megawatts of CSP plants under construction in the U.S, with many gigawatts more under development. Worldwide, more than 1 gigawatt of CSP is in operation. The International Energy Agency estimates that CSP projects now in development or under construction in more than a dozen countries (including China, India, Morocco, Spain and the United States) total 15 gigawatts.

Utilities and grid operators worldwide value CSP plants because of the technology’s ability to:

• Produce electricity at peak demand when it is needed most during the late afternoon or early summer evening hours or winter mornings.

• Include cost-effective, efficient thermal energy storage to provide a flexible and dispatchable clean energy source, day or night.

• Incorporate into coal or gas power plants as “hybrids” for cleaner baseload power.

There are different designs for steam-producing CSP technology that incorporate storage. These include power towers, parabolic troughs and linear reflectors, each based on proven engineering principles.

CSP plants have also shown to be great creators of economic benefits in the regions where they are built as well as across the United States. A recent study by Deloitte found that compared to other power generation sources, CSP plants are a strong generator of local jobs during construction, in operation, and maintenance. The supply chain feeding CSP plants create jobs nationwide as well, due largely to the plant’s high percentage of domestically-sourced components . Another study commissioned by the U.S. National Renewable Energy Lab for the Department of Energy found that a 100 megawatt CSP plant creates more than $600 million in impact to gross state output, ten times that of a combined cycle fossil plant due to the local content and job creation.

The formation of the CSP Alliance builds on the momentum following the creation of the World Solar Thermal Electricity Association (STELAWorld) a consortium of industry associations representing the solar thermal electricity industry in Europe, Australia and South Africa. While independent of STELAWorld, the CSP Alliance will work closely with these associations to further advance the solar thermal industry in the U.S. and abroad.

CSP is poised to grow worldwide, creating clean power and jobs as it expands to meet the world’s energy needs. Current CSP projects demonstrate the technology’s viability and a recent study from the International Energy Agency shows that with sufficient investment and the right government policies, more than ten percent of the world’s electricity demand could be satisfied by CSP by 2050.
