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
