2.0 PROJECT OVERVIEW
LET is partnering with Philadelphia Gas Works to design and construct a new Liquefaction System,
with the implementation of a Solar field to the Facility located at the PGW Passyunk site in
Philadelphia, Pennsylvania.
The inclusion of a solar field will be utilized as an additional power source to assist in running the
plant, and therefore lessens the burden of only utilizing the grid. Approximately seven (7)
megawatts (MW) is required to run the plant and all its loads;
LET plans to install 3 MW solar on approximately twelve (12) acres. The current planned location
has sufficient land and infrastructure to accommodate such configuration. However, as shown in
drawing E20, there are monitoring wells located throughout the facility which, upon request,
must be left with at least 14ft of space between each solar array for the ease of a truck to
perform any maintenance on the wells.
As portrayed in drawing PEC-0001-E20, LET created a conceptual layout indicating the areas that
are available for solar panels installation. Bidder shall select areas to install solar panels and shall
produce 3MW of solar power that shall be inverted, and stepped-up to 4,160 VAC and tied
upstream of the 4,160 VAC switchgear. Utilization of future battery storage shall be included to a
minimum of one of the areas and be considered in the design.

3.0 SCOPE OF WORK
The below scope of work (SOW) outlines the requirements for the project:
