Waste Conversion Project Procurement / Solar & Wind Project Procurement (Prince William County, Virginia)

Prince William Energy Park (PWEP) – Technical and Economic Feasibility Study and Project Plan

GBB was selected to explore the renewable energy technologies available for use on the County landfill.  For technologies found to be applicable for the site, GBB investigated their technical requirements and limitations, order-of-magnitude costs, revenue potential, market maturity and acceptability.  GBB also analyzed and presented implementation options for the Prince William Energy Park (PWEP), including ownership options, financing and cash flow implications, risk allocations, management roles and requirements, procurement implications, and present the options to the County.

Based on the results of the analysis and the procurement process selected by the County, GBB prepared a preliminary development plan outlining the potential uses of the site, the roles and responsibilities of the development team members, the scheduling of the development process, and preliminary financial projections for the County.

As part of the feasibility analysis, GBB considered the impact of the redevelopment of the site on the regulatory requirements for post-closure care, on-site and off-site land use and environmental considerations, permitting requirements, electrical interconnection requirements and costs, energy markets, funding sources, development costs of the County, procurement issues and other related matters.

Solar/Wind Project Procurement

As part of the Prince William Renewable Energy Park (PWREP), GBB was selected by Prince William County to assist with the development of solar and/or wind energy project(s) at its landfill. The project included the procurement of a full-service design-build-own-operate developer or developers of such project(s).

In coordination with the County, GBB developed and issued an RFP for the project(s) and assisted the County in evaluating responses, recommending the most advantageous project or combination of projects and negotiating a development agreement with the selected developer(s).  The RFP will describe the opportunity for potential developers, who could then submit their qualifications and complete technical and financial proposals. The County planned to involve both the PWREP Development Advisory Team and the PWREP Citizens’ Advisory Committee in this process. GBB provided technical assistance to the County, as well as support  and coordination of the activities of those two special groups.

Program Planning and Management

GBB provided the general program planning and management tasks preparatory to the implementation of the renewable energy projects envisioned in the Preliminary PWREP Concept Plan. Work included finalizing the development plan, program and development team, supporting the County and its advisory groups in the development of the final plan, creating an overall site development plan, negotiating arrangements with respect to landfill gas availability, electrical interconnection and academic support for the proposed Sustainability Center, and performing other analyses and general tasks related to program management.

Waste Conversion Project Procurement

GBB assisted with the development of a demonstration plant (≤100 ton/day) of an emerging MSW WTE conversion technology (e.g., pyrolysis, gasification, anaerobic digestion, plasma torch, etc.) at the landfill. The demonstration plant will be part of the PWREP. The first step of the procurement process identified and described the opportunity for possible developers and  the second step involved asking a short list of qualified potential proposers for a complete technical and financial proposal. The County planned to involve both the PWREP Development Advisory Team and the PWREP Citizens’ Advisory Committee in the process. GBB provided technical assistance to the County, as well as support to and coordination of the activities of those two special groups.
