The Federal government is the largest energy consumer in the United States, with new mandates to meet increased demand, reduce peak operating costs, enhance energy security, and improve the reliability of electric power generation.


IPU works with federal organizations to design, build and, in many cases, own, operate and manage energy projects via power purchase agreements.  We can develop energy projects that eliminate the need for significant taxpayer funding by sourcing financing through cost savings generated by increased energy efficiency and reduced emissions.

IPU can help federal facility managers to achieve these key goals:

  • Increase resilience by enabling the installation to rely less on the existing power grid
  • Upgrade or renew facilities with no up-front cost by leveraging private sector financing
  • Enhance energy security due to power facilities located onsite
  • Reduce energy consumption and operating costs
  • Capture opportunities created by deregulation, such as bulk purchasing of commodities and real-time pricing strategies
  • Meet benchmarks for energy conservation and renewable energy use

Waste Water Treatment

CHP is a reliable, cost-effective option for Waste Water Treatment Facilities (WWTF) that have, or are planning to install, anaerobic digesters.

The biogas flow from the digester can be used as fuel to generate electricity and heat in a CHP system using a variety of prime movers, such as reciprocating engines, micro turbines, or fuel cells. The thermal energy produced by the CHP system is then typically used to meet digester heat loads and for space heating. A well-designed CHP system using biogas offers many benefits for WWTFs because it:

  • Produces power at a cost below retail electricity.
  • Displaces purchased fuels for thermal needs.
  • May qualify as a renewable fuel source under state renewable portfolio standards and utility green power programs.
  • Enhances power reliability for the plant.
  • Produces more useful energy than if the WWTF were to use biogas solely to meet digester heat loads.
  • Reduces emissions of greenhouse gases and other air pollutants through the displacement of utility grid power along with the elimination of the breakdown of organic material in the waste stream.
