New Report Highlights the Power of Geothermal

The Geothermal Energy Association (GEA) and Geothermal Resources Council (GRC) have released a new joint report, “The Values of Geothermal Energy: A Discussion of the Benefits of Geothermal Power Provides to the Future of U.S. Power System“. The report addresses the role geothermal energy can play in states with Renewable Portfolio Standards (RPS) or Renewable Electricity Standards (RES) who are considering the full value of the power sources they use.

The Value of Geothermal ReportThe report was prepared by Ben Matek, GEA’s Industry Analyst, and Brian Schmidt, Librarian, GRC, and documents the many benefits of geothermal power.

“Geothermal power offers both firm and flexible solutions to the changing U.S. power system by providing a range of services including but not limited to baseload, regulation, load following or energy imbalance, spinning reserve, non-spinning reserve, and replacement or supplemental reserve,” the report begins.

Looking beyond the benefits to the power system, the report also summarizes other key benefits of geothermal power including economic and environmental benefits. “We are often asked about the full range of services and benefits available from geothermal,” Matek said. “So, we decided to join with GRC and put out a white paper that addresses these questions.”

“This is a timely report,” added Karl Gawell, GEA’s Executive Director. “The California PUC recently noted active questions before policy makers in California and elsewhere, specifically: ‘how increasing amounts of intermittent generation are impacting grid reliability, quantifying the impact and benefits of various resources to integrate intermittent generation, and what new policies should be adopted to manage the changing electric grid.’”

As the report indicates, these questions are gaining in importance as the United States expands its renewable power production, which today means “generating approximately 14% of the electricity” nationwide. Much of this is coming from wind and solar photovoltaic technologies that rely heavily on the prevailing weather conditions in order to generate power. However, the report note that “Geothermal energy is a renewable power source that can provide baseload and flexible power, quickly adjusting to fit the needs set by variable renewable energy technologies.
