Challenged with increasing demands, limited resources, and an aging infrastructure, energy providers need to examine system reliability and pursue renewable and alternative sources of energy.

From generation to transmission, energy projects must also withstand increasing regulatory and public scrutiny and often traverse multiple jurisdictions.

ESA brings decades of experience in assessing and minimizing environmental impact and navigating the often complex permitting and licensing processes for energy projects. From power producers to refineries, we help our clients create projects that are economically sound and environmentally prudent.

We understand the dynamic and complex regulatory and funding framework for energy projects. We’ve managed the environmental analysis and permitting of more than 1,000 miles of electric transmission line and related infrastructure improvements, and more than 20 renewable energy projects including wind, solar, geothermal, and biomass.
