The purpose of this legislation, known as the Geothermal Tax Parity Act, is to update the tax code to support the exploration and development of geothermal energy. It aims to provide financial incentives for companies involved in geothermal projects by allowing them to amortize certain geological and geophysical expenses. This change is intended to encourage investment in geothermal resources, which can contribute to cleaner energy production. Key provisions of the act include two main amendments to the Internal Revenue Code.
