The Philadelphia Navy Yard Story: The Remarkable Emergence of an Unintentional Microgrid

via Microgrid Knowledge

Under the management of Rudy Terry, director of smart grid operations, the Navy Yard energy assets now include:

  • 8-MW natural gas generator, built and operated by Ameresco. The system has four continuous duty RICE engines, each connected to 13.2 kV generators that output directly to the 602 substation bus (a primary PECO facing substation). The generators are operated economically in direct peaking service and in PJM service for their energy and reserve market.
  • A 600-kW Bloom Energy fuel cell plant, owned by Urban Outfitters and net metered by PIDC
  • A 400-kW rooftop community solar installation that was built, owned and operated by AEDG under a power purchase agreement with PIDC. Five customers, virtually net metered within the Navy Yard, have shares in the community solar. A second, larger rooftop solar plant project is in the formative stages.
  • The Navy Yard has contracted for limited, but priority use of a 6.2 MW/14.8 MWh energy storage system (Li-ion battery), to be built, operated and owned by a project company backed by Citizens Energy.  NEC is the solutions provider.
  • Penn State and ProtoGen have created an intra building advanced microgrid with support of hybrid distributed energy resources under a DOE grant. The microgrid within the microgrid is the final testing stages of a multi-year effort.
