DOE Funds Huge Solar Project

Loan guarantees will help finance 400 megawatts of solar power.
By Kevin Bullis

The U.S. Department of Energy has announced a $1.37 billion conditional loan guarantee for the Ivanhoe Solar Complex in the Mojave Desert. The project, managed by Brightsource Energy, will use mirrors to concentrate sunlight, creating high temperatures that can be used to generate electricity. The complex will include three power plants that together will produce about 400 megawatts of electricity.

Basically, the guarantees would cover the loans in the case of default. The money for the loans is expected to come from the Federal Financing Bank.

One of the biggest challenges that large solar developments face is getting financing, particularly because few such solar power plants have been built. The DOE guarantees help on this front.

But other challenges remain, including getting approval from the government to actually build on the chosen sites, and clearing the National Environmental Policy Act review. The application process for the plants started nearly 3 years ago, and construction on the sites has already been delayed. Before the process is over, new hurdles might get thrown up, a possibility illustrated recently when Senator Dianne Feinstein (D-CA) submitted legislation to ban solar projects from some parts of the Mojave desert, a move that threatened several projects already in the works.

  • Conventional PV vs. Concentrating Solar Thermal
    Power tower technology like BrightSource's and conventional CSP have enormous capital requirements and require large amounts of water in a regions where water is scarce. The kWh cost of energy is usually competitive with subsidies as is large scale photovoltaics (PV). PV is a simpler install, eliminates the need for water and has a lower price tag. With the price of PV, a mature technology, dropping dramatically, its interesting to see large government backing for this type of high cost unproven technology that has site development issues as outlined in the post above.

  • Who is lending the Money
    I do not believe the statement “the money for the loans is expected to come from the Federal Financing Bank” is correct. DOE is guarantying private lenders and is not lending the money itself.
