Mexico’s Geothermal Market Assessment Report

NREL Technical Report

Francisco Flores-Espino

Recent changes in Mexico’s energy sector, combined with the government’s ambitious clean energy targets and a variety of other factors, have created favorable conditions for investment in the country’s geothermal energy sector. Since 2013, Mexico has enacted comprehensive reforms to open significant components of its energy sector to private investment and accelerate the deployment of new renewable energy generation. These energy reforms present the most significant change to the electricity sector in the country in the last few decades. This report is intended to help U.S. companies in the geothermal sector understand potential business opportunities created by these recent changes in the Mexican energy market and regulatory environment.


Solar Field Optical Characterization at Stillwater Geothermal/Solar Hybrid Plant

Journal of Solar Energy Engineering

Guangdong Zhu and Craig Turchi

In this work, an extensive measurement on mirror slope error and receiver position error has been performed in the field by using the optical characterization tool called distant observer (DO). Combining a solar reflectance sampling procedure, a newly developed solar characterization program called firstoptic and public software for annual performance modeling called system advisor model (SAM), a comprehensive solar field optical characterization has been conducted, thus allowing for an informed prediction of solar field annual performance. The paper illustrates this detailed solar field optical characterization procedure and demonstrates how the results help to quantify an appropriate tracking-correction strategy to improve solar field performance.
