Madrid, Spain-based renewable energy company GA-Solar and its parent company, Spanish steel manufacturer Corporación Gestamp, announced late last month they will build a $1-billion, 300-MW photovoltaic solar project near Santa Rosa, N.M. The project is expected to take up to four years to build on a 2,500-acre site. The company says it will obtain racking equipment and possibly inverters and steel from local sources. The project joins about 20 other utility-scale solar projects in New Mexico that are in the planning stages and total 1,815 MW.
