LRE (Leeward Renewable Energy) is forging an American energy future with integrity, innovation, and positive impact. Born in Texas in 2003, we own and operate over 30 utility-scale wind, solar, and energy storage projects in local communities across the United States, totaling 4 gigawatts (GW) of generating capacity. LRE continues to help meet increased U.S. energy demand through our robust pipeline of new projects every year. Domestic jobs and manufacturing are fundamental to our full-lifecycle approach to projects, along with a long-term ownership model and a company culture dedicated to our community partners and protecting the natural environment. Job Summary: The High Voltage (HV) Technician is responsible for the safe, reliable, and compliant field execution of operation, maintenance, testing, and troubleshooting activities on high-voltage electrical systems across renewable energy facilities. This includes substations, switchyards, transformers, breakers, relays, battery energy storage systems (BESS), MV collection systems, and transmission or generator tie-lines. The HV Technician serves as the field execution arm supporting internal Engineering, Asset Management, and Operations teams by performing hands-on HV work, gathering field data, executing switching and maintenance activities, and supporting troubleshooting efforts under established procedures. The role emphasizes safe work execution, equipment familiarity, and operational discipline, rather than engineering design or system modeling responsibilities.
