Selected Achievements:

  • Assisted Stirling Energy Systems with successfully negotiating a 20-year power purchase agreement with Southern California Edison and San Diego Gas & Electric to develop the world's two largest solar power projects in the desert region of southern California. Under the agreement with Edison, Stirling will deliver 500 MW of solar power from the SES Solar One project, with an option to expand to 850 MW. Under the agreement with SDG&E, Stirling will deliver 300 MW from the SES Solar Two project, with the ability to expand to 900 MW. Together, the two projects will dwarf the combined capacity of all existing solar power plants.

  • Advised federal and local public entities and ESCO developers in modifying California's Self- Generation Incentive Program to successfully CHP and hybrid wind and solar alternative energy projects come on line.

  • Negotiated a long-term contract to develop a start-up biomass pelletization project to provide sustainable energy fuel supply to co-fire fossil fueled electric generation projects in Europe.

  • Advised start-up energy services companies in the United States, Canada, the United Kingdom, Germany, and Spain.

  • Developed standard retail natural gas and electricity supply contracts and modular administrative systems that are models for the industry.

  • Negotiated design/build construction contracts for the energy services field, including the Federal Drug Administration's largest facility at Whiteoaks, Maryland, and many others.
