The authority will hold a non-mandatory pre-proposal conference on March 16 at 1 pm ET for those interested in participating in the request for proposals (RFP).

The RFP seeks a consultant to develop a road map and feasibility studies for the project. The roadmap will identify a portfolio of projects to be implemented over time.

Proposals are due May 5, 2022 (DCW-SOL-22-10161). The authority anticipates awarding a single, three-year contract for an estimated amount of $4 million.

DC Water hopes to achieve a series of goals through the microgrid project, among them:

  • Improve safety by replacing manual load switching with remote control load switching 
  • Maintain electric reliability
  • Reduce operational costs
  • Invest effectively in infrastructure
  • Enable management and optimization of distributed energy resources at Blue Plains
  • Expand power analytics and reporting
  • Improve power quality
  • Support Sustainable DC climate goals
  • Improve energy resilience

The March 16 pre-proposal meeting is virtual and can be accessed via a Microsoft Teams meeting, or by calling 202-753-6714, phone conference ID: 375 503 035#

  1. A great example of a microgrid to move on to another platform. I think wastewater is more than just waste. Along with the treatment process, useful products such as biosolids and energy are extracted for reuse and the clean water flows into the Potomac River.

  2. There may be no better concept for a microgrid hat serves a city than one that uses the city’s municipal trash as fuel and one that can also gasify solids in the process and one that can use the methane from gasifying those solids as a supplemental fuel source.
