distributed generation
Distributed Generation
  • small scale environmentally friendly technologies
  • installed on and designed primarily to serve a single end-user’s site
  • any generation built near to a consumer’s load regardless of size or energy source
virgin islands dg public policy goals
Virgin Islands DG Public Policy Goals
  • Secure Partnership with WAPA
  • Research utilization of renewable/alternative energy resources as Distributed Energy Resources
  • Conduct workshops for WAPA governing Board, the PSC and general public
  • Development and Implementation of an interconnection policy for the Territory

birch state park
Birch State Park
  • 5 kW grid tied fuel cell
  • Unit contains two major components:

The fuel processor and power conditioner

findings on the fuel cell unit plug power model su 1
Findings on the Fuel Cell unit Plug Power Model SU-1
  • the fuel reformer processes a hydrocarbon fuel into a hydrogen rich gas
  • the power conditioner converts the low voltage current produced by the fuel cell to a high voltage DC
  • An inverter transforms the high voltage DC to 120 or 240 volts AC
  • Batteries in the power conditioner ensure sufficient coverage for power surges
  • consider the more cost effective 200 kW model that uses a phosphoric acid membrane
findings on the fuel cell unit plug power model su 11
Findings on the Fuel Cell unit Plug Power Model SU-1
  • Provides 5 kW to park operations office
  • Utilizes natural gas as an energy source (model Genesis 5C utilizes propane gas)
  • H electrons and protons separate through PEM the (membrane) system
  • Power produced per unit of energy has an efficiency rating between 30 – 55%
  • An interconnection policy exists
  • Grid tied utilizing dual metering system
problems within fuel cell unit
Problems within Fuel Cell unit
  • system is only about 25% efficient
  • water purification problems caused by algae

importance of dg research
IMPORTANCE OF DG RESEARCH
  • Implementation of Act No. 5006 which amended Section 1, Title 30, of the Virgin Islands Code. This allows small power production facilities to interconnect with the local electric utility and sell excess generated electric energy to that utility.
  • To pilot ten photovoltaic grid-interconnected small power production systems for grantees who submitted innovative renewable energy proposals
importance of dg research1
IMPORTANCE OF DG RESEARCH
  • Assist the PSC determining such requirements relative to the minimum size, fuel use and efficiency of a “Qualifying Cogeneration Facility”.
