Scarcely a month passes without at least one caller to John Geyer & Associates, Inc. seeking “real-world” operating cost data for geothermal heating systems. Cost and complexity of utility-grade monitoring and verification (“M&V”) protocols makes such data uncommon and selective. Nobody wants to spend money to document results after installation. As a result, unfounded perceptions, as held by Bonneville Power Administration and West Coast investor-owned utilities are that “Geothermal heating and cooling is not cost effective here”, regardless of where “here” may be. This view persists despite 15,000 to 20,000 operating geothermal systems in Northwest service areas and perhaps half as many more in California
