Challenged to meet the integration of utility-scale renewable generation, traditional grid technology, and the influx of distributed generation, energy providers and regulators are examining and adapting their existing systems throughout the western United States.
ESA understands the dynamic and complex regulatory and funding framework for energy projects, which often involves proactive engagement with the public and the coordination of multiple jurisdictions.
We have managed the environmental analysis and permitting of more than 1,000 miles of electric transmission line and related infrastructure improvements. We have analyzed more than 12,000 megawatts (MW) of solar energy and nearly 3,000 MW of wind energy, as well as geothermal and biofuel energy generation projects on both private and federal lands. We bring direct experience with feasibility and site selection studies, site planning, impact assessment, licensing, permitting, monitoring, restoration, and public involvement.
From regulating agencies to power producers, refineries, and surface mining concerns, we help our clients realize projects that provide reliable energy services.

The ESA Drone Program has recently added three 5-band precision sensors to our fleet, which will support a range of natural resource assessments. With this gimbal technology mounted on our DJI Inspire 2 drones, we can collect visual band (RGB) imagery as well as vegetation indices with near infrared (NIR) spectroscopy (or RedEdge), including normalized difference vegetation index (NDVI), a method of determining whether an area contains live green vegetation.
