Bear Creek Mountain
Resort & Conference Center
● Located on more than 330 acres in Berks
County, Pennsylvania.
● The resort has gone thru several expansions,
adding a 65-room hotel, multiple additions to
ski lifts, a new pump house, and 125 high-
powered snow guns.
● There is a 5 MVA cap on incoming power from
the Utility due to transmission constraint
● In warmer weather, the resort must run in
“heavy snow-making mode” the resulting
facility load can reach 7.2 MVA.
Solution Includes
● Load forecasting algorithm
● Menu driven load prioritization
● Automatic load and generator management

GSA St Croix 100% Net Zero (DOE ESPC)
This is the first federal building to achieve 100% Net Zero
Energy through an ESPC. Schneider Electric is guaranteeing
a total of $13,496,819 in energy savings and renewable energy
production over the 18 year contract term ($508,077
guaranteed in Year 1).
Schneider Electric’s ESPC at the Almeric Christian Federal Building will enable the site to reach 100% Net Zero Energy.
This project will install
enough energy efficiency
improvements and
renewable energy systems at
the site to achieve Net Zero
Energy status – that is, the
GSA will eliminate 100% of
their brown power annual
energy use at this site – with
no upfront capital required.
• Utility: PREPA
• ~5GW of utility generation capability, but generation is not ideally located vs. loads
• Leads to voltage, frequency issues
• Can be considered to operate as a very large-scale microgrid
