What stops banks from lending to energy efficiency projects?

Four years after the US credit market crashed, energy efficiency projects continue to struggle to secure financing.

What’s the problem? A slow economy, of course. But when it comes to energy efficiency – and on-site renewable energy – the problem runs deeper.

It’s not lack of interest in green energy. To the contrary, says Angela Ferrante, director of alternative energy solutions at Energi, a Massachusetts reinsurance company that provides  insurance and risk management products for the energy industry.

Banks are interested in lending to green  projects, in part because of the number of customers now knocking on their doors seeking financing for energy efficiency and solar installations.

“When they hear it from their clients, it is a lot more compelling than hearing about green so and so in the newspaper,” she said.

In addition, banks see energy efficiency as a new market opportunity. Energy efficiency is experiencing rapid growth and strong government support, especially in the pricey energy markets of California and the Northeast.

“Banks are faced with new regulations and  they are trying to see what types of products they can diversify into,”  Ferrante said.

But lenders become spooked when they begin to evaluate the risks associated with energy efficiency and on-site solar.

For example, energy efficiency and solar companies often base their sales pitch to the customer on guaranteed energy savings. Many deals are structured so that the customer pays for the energy equipment with money saved on energy bills. What if something goes wrong and the energy savings do not materialize? Will the bank be unable to collect on the loan? And what serves as  collateral? If the loan goes into default, does the bank go into the home, office building or factory and rip out the solar panels, lighting, efficient motors, or insulation? Not likely.

Energi is attempting to “de-risk” green energy projects for lenders and energy developers with new insurance and warranty products. One such product, energy savings warranty insurance, backstops the promised energy savings, even for small contractors and energy service companies (ESCOs).

Larger ESCOs have been able to offer such guarantees on their own because of their size and their clientele, which is often the financially stable ‘MUSH’ market – municipal/university/ schools/hospitals. But it has been difficult for smaller companies and contractors, who serve businesses and homes, to do the same.

Thus, such insurance products could be “game changers,” said Kevin Kaminski, Energi senior vice president of alternative energy solutions. Warranty insurance gives smaller energy companies the ability to offer clients the same kind of favorable terms as the larger players – and the smaller companies can literally take the deals to the bank as a low-risk proposition.

As federal funds and incentives become more scarce, the green energy industry is likely to see more and more innovation in financing like the Energi products. Solar gardens are another example of emerging innovation, as well as real estate investment trusts and master limited partnerships (MLPs), a form now allowed for oil and gas investment, but not renewables.  For more details on solar gardens and MLPs, see my article “US renewables: New financial models” in the November 2012 issue of Platts Energy Economist.

  1. Great article Elisa, and as banks continue to struggle with getting comfortable with energy efficiency financing, many alternatives are emerging and making significant impact, including out energy efficiency equipment lease model. We are funding transactions on a daily basis for a variety of measures for a wide range of clients.

  2. If I hire a contractor to reroof my house and 2 years later it leaks, I know that the contractor is at fault and so does the company holding the warranty. No questions.

    If I get my house insulated and two years later my heating bills are up, what went wrong? Is the price up? Did the installation fail? Am I heating my house to a higher temperature? Did the insulation get wet because my roof leaked? Did my heating costs go up because I stopped watching that 72 inch TV 24 hours a day? How do I know and how will the company holding the warranty know who is at fault?

    Perhaps banks don’t get involved with the risk in energy efficiency because it doesn’t make business sense.

  3. Great article. It is rather unfortunate that over the last several years, the travel industry has already been able to to handle terrorism, SARS, tsunamis, influenza, swine flu, and the first ever real global tough economy. Through everything the industry has proven to be effective, resilient plus dynamic, locating new strategies to deal with adversity. There are often fresh issues and opportunities to which the field must yet again adapt and respond.

    The most recently developed wind-turbine technologies have brought us wind-produced energy which is more cost efficient as well as more widespread. More state-of-the-art wind energy technologies are typically more market competitive with conventional energy technologies. The newer wind-power technologies don’t even kill birds like in days of old! Wind energy production is a growing technology, and companies engaged in it would make up an excellent part of a growth or aggressive growth portfolio.;
