Medina Public Works Facility PV Installation

Medina Hennepin County Public Works Faclity

After choosing a technology and identifying a site, the next step is to find a solar developer. Soliciting bids for solar energy installations and then choosing a developer can be time consuming and complex. Streamlining the decision-making process by creating standard solicitation forms and establishing the appropriate evaluation criteria and process up front saves time and yields a better result.

Implementing a solar project on public facilities in MN can include either releasing a request for proposals (RFP) to solicit bids for photovoltaic (PV) or solar water heating (SWH) installations or entering in contract for service agreement.

By using a well-crafted RFP and evaluation process, a community can streamline the procurement effort and generate interest from multiple solar developers. Standardizing these processes makes it easier to solicit industry proposals for future installations and work across various city or county departments.

Depending on the financing model chose for a solar installation, an agency may have the option of issuing an RFP or signing a Contract for Service with the solar integrator. The factors that will determine which is best include:

  • Type of solar financing model used. The direct ownership model will almost always require going through an RFP process because of the purchase amount. PPAs and leases may not require an RFP.
  • State policies permit local authorities to enter into a Contract for service if the initial outlay of capital is under $2,500. This is often the case with PPAs and solar leases. Some local jurisdictions have instituted stricter policies though. (Statute on energy efficiency installment purchases is Minn.Stat. 16C.14)

The documents that specify the requirements for the installation, typically include things such as system size or energy output, technology type, installation location, and cost range. The proposal requirements will vary if they are for a power purchase agreement (PPA) rather than a design-and-build contract.

Another model that has seen great success in the residential and commercial markets is bulk-purchasing. Public agencies can potentially see great savings on equipment and time saved on project planning by bundling projects. This is another strategy to get a more competitive PPA also.

Sample Requests for Proposals | Vote Solar Initiative

The Vote Solar Web site has several sample RFPs for direct purchases as well as PPAs.

 

RFP Library | NASEO ARRA Portal

The RFP Library is a resource of requests for proposals (RFP) under ARRA-funded programs and projects. Please note that this library offers sample RFPs used by states for State Energy Program (SEP), Energy Efficiency and Conservation Block Grant (EECBG), and State Energy-Efficient Appliance Rebate Program (SEEARP) projects. The RFPs are not peer-reviewed, nor do they serve as a reflection of the best projects. This library is intended to showcase a variety of RFP options that can then be adapted based on your state’s specific needs.

 

Best Practices Guide for Buying Solar Systems | World Resources Institute

This web site includes a recently developed best practices guide, case studies, and template documents for public and private groups who want to leverage their buying power to decrease costs and improve vendor performance.

 

Solarize Guidebook | U.S. Department of Energy

This guidebook describes key elements of the Solarize campaigns in Portland, and offers several program refinements from projects beyond Portland. The guidebook provides lessons, considerations, and step-by-step plans for project organizers to replicate the success of Solarize Portland.

 

Purchasing Power: Best Practices Guide to Collaborative Solar Procurement | World Resources Institute

This Best Practices Guide is intended to assist commercial and government entities in the process of organizing and executing a collaborative solar purchase. A measure of success will be the number of readers who use this guide in purchasing solar power to meet their electricity needs more sustainably and at an affordable price. The guide outlines a list of best practices, which together constitute a 12-step process to capture the economic and practical benefits of a joint purchase. The starting point for participating in such an effort is simply an interest in purchasing solar electricity. The best practices are intended as a resource for project planning and decision making. They provide specific actions in chronological order, with milestones to indicate when to move from one step to the next. The end goal is that regional groups of participants will have solar PV installed on their facilities at competitive prices.
