PROFESSIONAL EXPERIENCE
CH2M HILL, Austin, Texas 2007 - 2014
Solar PV Program Manager
Built a talented team to deliver quality engineering for U.S. and international clients. Led solar team
of five with support from 100 power engineers to implement distributed and large-scale solar PV
designs. Developed new business with clients to implement solar, energy efficiency and biomass
programs. Here are representive projects:
UTILITY-SCALE PV PLANTS, Recurrent Energy, Ontario, Canada, 2010 - 2014
Led team to write technical specifications and support plant commissioning for 19 solar PV
projects each up to 10 MW. Enabled Recurrent Energy to sell the 19 projects worth $600M by
March 2014 to investors.
1 MW PV SYSTEM DESIGN, Silver Peak Mine, Nevada, 2014
Directed development of cutting edge design and construction plan for 1 MW PV plant with a
battery storage system to shift solar production.
200 MW SOLAR PV PLANT, Laughlin, Nevada, 2013
Drove development of preliminary designs, layouts, electrical one-line diagrams, PVsyst
modeling, cost estimates for 200 MW solar PV plant near Mojave Substation. Client bid into San
Diego market for between 5 and 6 cents/kWh; a record low price for utility-scale PV.
2 MW SOLAR PV PLANTS, PacifiCorp, Oregon and Utah, 2010 - 2014
The team wrote technical specifications for the client to hire an EPC contractor to build and
commission the PV plants. Reviewed drawings and construction submitttals. PacifiCorp was
able to procure and build the PV plants on time and under budget.
MASDAR CITY DEVELOPMENT, Abu Dhabi, United Arab Emirates, 2008 - 2010
Managed team providing technical design, procurement, installation and commissioning for the
10 MW PV system. The plant was completed and commissioned in 2009, the first large-scale
plant in the Middle East. The project included energy efficiency measures and biomass analyses.
DUE DILIGENCE, Marubeni, 150 MW PV Plant, Australia 2011, and TransCanada for a
$400M investment in a PV in Ontario, Canada 2010 - 2011
Led team to conduct technical due diligence: Marubeni, was considering investing in the
Australian Queensland project, and our team worked with TransCanada for a full year
evaluating an opportunity that allowed them to invest in PV plants worth $400 Million.

generation plan. Worked with key stakeholders to develop utility specifications and standards for
renewable plants including large-scale and distributed generation. Led installation of two 300 kW
photovoltaic plants and several small systems on city buildings. Negotiated purchase power
agreement for 10 MW landfill gas power plant and 10 MW share of Culberson County wind plant
built in partnership with Lower Colorado River Authority (LCRA); the first utility-scale wind farm in
Texas. Worked on committees for Texas Public Utility Commission to write state interconnection
standards for state.
Trinity University, San Antonio, Texas 1981 - 1983
Graduate Research Fellowship
