Geothermal Electricity

In some parts of Oregon, geothermally heated groundwater can be harnessed to produce renewable electricity. Energy Trust can help you explore the potential of low-temperature geothermal resources to generate electricity at your site.

  1. Establish your eligibility.

    Read More >

    To be eligible for an Energy Trust incentive, a geothermal project must:

    1. Be less than 20 megawatts in nameplate capacity (maximum rated output).
    2. Be located in the service territory of, or deliver power to, Portland General Electric or Pacific Power in Oregon.
  2. Give us a call.

    If you have a geothermal resource and are interested in using it to generate electricity, contact Dave Moldal at 503.445.2476.

  3. Get the help you need.

    Depending on your project’s complexity, you may need a feasibility study or expert assistance to move through permitting or utility interconnection. Energy Trust may provide up to $200,000 in support for these and other types of project development activities, and we can help you identify engineers or other experts with the experience to help.

Project Development Assistance

Energy Trust provides support for expert project development assistance including, but not limited to, grant writing assistance, feasibility studies, final design, permitting, utility interconnection and construction management. We may pay up to 50%, up to a maximum of $200,000, of the cost of hiring an outside consultant to provide expert assistance for these activities.

Installation incentives

Incentive levels are based on a project’s cost in comparison to the market value of the energy produced, called above-market cost. There is no cap or fixed percentage of the amount of above-market costs we will pay. In return for our funding contribution, we ask for a negotiated share of the project’s Renewable Energy Certificates, which are held in trust for the ratepayers who contribute to Energy Trust.

Incentives are subject to funding availability and may change.

Interconnection information

For first-time developers, the utility interconnection processes can seem especially daunting. As described on the Details tab, Energy Trust offers Project Development Assistance incentives to encourage developers to engage professionals to speed up the development process.

These guidebooks have been written for both new and experienced developers and are intended to serve as a roadmap to Oregon’s utility interconnection process.
