Fossil Fuel Generation & Conversion

Electric Generation FacilityFor more than 20 years, ESS has provided environmental consulting and engineering services for power generation projects and related fuel storage and transmission facilities. ESS offers full life cycle support for its energy industry clients - from site selection, permitting, and construction to operational compliance and decommissioning support.

Project Success - Building Capacity, Reliability & Environmental Benefits

Many ESS power generation projects are now either under construction or in operation. These projects provide added generation capacity, improved reliability, and/or environmental benefits. Many also provide power at reduced cost thanks to more diverse fuel supplies and/or more efficient operating technologies.

Successfully permitted ESS energy projects include:

  • New combined-cycle gas-fired power generation facilities
  • New and repowered cogeneration facilities
  • Conversion of existing oil- and coal-fired generation facilities
  • New and expansions of electric transmission and natural gas pipeline interconnections
  • Due diligence for the transfer of existing assets

Environmental Due Diligence for Energy Facility Transactions

The required environmental due diligence for acquisition and divestiture of energy facility assets is driven by a comprehensive suite of federal and state air, water, and waste laws and regulations. ESS assists sellers and buyers of energy facilities with evaluating the environmental issues which can aid in estimating the environmental liability and operation compliance risks. Our services include ASTM Phase I and II Environmental Site Assessments, visual inspection of assets/records, site investigations, identification of environmental enforcement actions, and estimating known and potential environmental liabilities.

Adapting to Changing Fuels & Air Regulations

The dynamic energy demand and pricing forecasts, fluctuating fuel prices, and roll-out of new regulations requires a deep understanding of the many factors influencing environmental assessments and permitting of energy generation facilities. ESS is committed to staying current with the changing market and regulatory conditions to offer our clients advice on using new technologies, retrofitting existing older facilities, and converting retiring facilities. Our focus is on finding practical, reliable, and cost-effective solutions in response to these influences. ESS has prepared impact assessments and permit applications for fluidized bed coal-fired cogeneration and integrated coal gasification combined cycle projects, as well as generation facilities powered by non-traditional fuels, like biomass/biofuel and recycled waste streams.
