A. Overview and Background of Project

Bucks County, Chester County, Delaware County and Montgomery County (each, a “County” and together, the “Counties”), working as a consortium known as the Sustainable Energy Partnership (“SEP”), are requesting bids for procurement and installation of 14 solar photovoltaic (“PV”) projects (each a “Project”) on county-owned properties within their respective jurisdictions. Each County has prioritized properties that are ready for solar installation. This Invitation to Bid (“ITB”) seeks bid proposals from qualified contractors (each, a “Bidder”) to procure and construct each County’s Project(s).

Montgomery County is disseminating this solicitation on behalf of SEP and each of the Counties. In order to streamline the response effort, Montgomery County's bidding platform - known as Bonfire - will be used, as described below. Each County will make its own separate procurement decision regarding whether to proceed, and if they decide to proceed, which approach to pursue.

The Counties are considering two financing structures for the Projects. In the first (hereinafter, the “Direct

Pay”), the County would be the direct owner of its Projects, would finance the projects through a combination of available cash resources and tax-exempt debt, and would attempt to benefit from federal investment tax credits (“ITC”) through the direct pay option for non-taxpayers. In the second (the “Power

Purchase Agreement” or, “PPA”), the County would transfer the right to contract with the winning bidder for the project (along with an Operations and Maintenance Agreement) to Capital Good Fund or an affiliate

(together “CGF”) and CGF would enter into a power purchase agreement (“PPA”) with the County to sell the County the power produced by the Project. CGF would be the owner and operator of the Project and would use the ITC to reduce the cost of power to the Counties. CGF has safe harbored equipment prior to

December 31, 2025, and has entered into Letters of Intent with each of the Counties that will qualify the

Projects for the 2025 ITC regulations.

Both structures will also require an Operations and Maintenance agreement with the Bidder or its subcontractor.

As further described in the bidding requirements below, Bidders may bid on Projects for one or more

Counties but must submit a bid for all projects in any County for which they submit a bid proposal. Bids will be evaluated on a County-by-County basis. The Counties intend to award projects in aggregate across each county by project structure (PPA and/or Direct Pay) to the lowest responsive, responsible bidder to achieve administrative efficiency. But, the Counties reserve the right to award on a project-by-project basis.

The Counties will select the lowest cost, responsive and responsible bidder for the structure they believe is most advantageous.

With the exception of Bucks County (which is only pursuing the PPA structure), and the exception of the

Chester County CCP-West site (this is the only project of Chester County’s four projects for which they are only seeking Direct Pay bids), the Bidders shall provide two bids for each Project they are bidding on.

One bid (the “Direct Pay Bid”) shall reflect the use of the contractor's own Foreign Entity of Concern

(FEOC)-compliant equipment (i.e. not CGF's safe harbored equipment) and will be assessed in connection with the Direct Pay structure. The second bid shall reflect the use of the CGF safe-harbored equipment, provided as Schedule I and included in the bid form (Appendix B), and will be assessed in connection with the Power Purchase Agreement structure (the “PPA Bid”).

The Counties have not conducted a separate request for qualifications, however this solicitation includes mandatory pre-qualification requirements, as a prerequisite to submitting a bid. See Appendix A – Contractor Responsibility Certification Forms. Bidders for the Bucks County project shall be required to complete Bucks County’s separate Responsible Contractor Form in Appendix A as well.

C. Information About the Parties

1. Sustainable Energy Partnership of Southeast Pennsylvania (SEP)

The SEP consists of four Pennsylvania Counties located in the greater Philadelphia area. SEP was created upon execution of a Memorandum of Understanding among the Counties as a result of a study commissioned by the Counties. Through a public solicitation, the Counties selected Enel X Advisory

Services USA, LLC (“Enel X”) to perform the study. Working in close collaboration with the Counties, the study was undertaken to explore the different energy procurement approaches and structures that could best meet the Counties’ long term energy goals of low-cost electricity, long term price stability, increased transparency, integration of renewable energy, and ease of on-boarding additional to-be-determined members into an aggregation approach.

Upon completion of the study, SEP determined to pursue a managed portfolio with a dedicated PJM subaccount procurement program delivered through a qualified Pennsylvania licensed electric supply service provider (“Supplier”). This program designed for local government aggregations has been successfully deployed with the support of Enel X since 2006. Under this program, SEP has adopted a block/index structure whereby competitively bid wholesale fixed rate blocks of energy are being purchased with the balance of energy purchased on the hourly markets. SEP has also been considering renewable energy purchase opportunities sourced through a variety of methods which may include purchases from member renewable energy projects, long-term PPAs sourced by the Supplier, piggybacking off other government renewable energy solicitations, and SEP issued renewable purchase solicitations for on-site projects. The program is overseen by the SEP Board consisting of appointed

County members and the program is being implemented and managed in accordance with the SEP approved Energy Cost Management and Procurement Plan.

2. Pennsylvania Solar Center (PA Solar Center)

The Pennsylvania Solar Center (“PA Solar Center”) is a nonprofit, statewide project that provides a centralized hub of resources and information for anyone who is seeking to power their home, business, house of worship or community organization with solar power. The PA Solar Center offers technical assistance to tax-exempt organizations and businesses to go solar by connecting them with trusted professionals and financing through its GET Solar program. The PA Solar Center has served as a consultant for this solicitation and has compiled the drawings, specification and calculations, this includes but is not limited to the HelioScopes provided for each project.

3. The Capital Good Fund

CGF is a nonprofit financing provider, that provides long-term PPAs to make the benefits of solar energy accessible to community organizations throughout Pennsylvania. Pennsylvania BRIGHT Solar

Communities LLC is an affiliate of CGF who together with the PA Solar Center have previously partnered to bring solar leases to small businesses, nonprofits, and municipalities through PA Solar Center’s GET

Solar program.

In December 2025, CGF received nonbinding Letters of Intent from SEP participating Counties and purchased equipment to "safe harbor" the previously identified priority projects. This was to secure the

2025 ITC rules for an additional 4 years by officially commencing construction through purchasing equipment worth at least 5% of the system cost of the solar projects. Under 2025 rules, safe harbored projects are not subject to the Foreign Entities of Concern (FEOC) requirements, and are held to a threshold of 45% Domestic Content equipment to qualify for the ITC Domestic Content Bonus Adder.

CGF will prepare a PPA proposal based on the submissions of the selected Bidder(s) under this ITB. If

CGF's PPA pricing is selected as the preferred financing vehicle, CGF will enter into a PPA with the

Counties directly. If a Bidder’s proposal is selected by CGF, the Bidder will enter into an Engineering, Procurement and Construction (EPC) contract with CGF for the respective County’s projects that is mutually agreed upon. The County of Chester has not yet determined whether it will enter into a PPA through this solicitation process.

D. Summary of the Projects

A summary of all 14 projects are provided below. With the exception of the Bucks County project, and the

Chester County Prison Site West, each project includes two designs – one aligning with the PPA structure, utilizing the CGF safe-harbored Enphase micro inverters (Enphase), and the second designed to align with the Direct Pay structure that utilizes string inverters that will be supplied by the selected bidder (String).

The detailed designs of the Projects, including AC nameplate, for each County are contained in the

Helioscopes for each site, Schedule II. Electrical line diagrams and roof assessments are available for some projects, also found in Schedule II. The requirements for submitting Bids in accordance with the specifications identified and provided for each site are provided in Section E.6 of this ITB. This section also defines all additional project requirements.

Insurance: See Exhibit 5 in form of Contract attached as Appendix E. Please describe what entities will be required to hold insurance that will cover any damage to the solar property after installation.

E. Safety of workers. Describe your company/subcontractor policies and procedures for ensuring safety for the workers on site and for others who are present at the worksite.

F. Public Works Employment Verification. This project falls under The Commonwealth of

Pennsylvania enacted Act 141 of 2022, known as the Public Works Employment Verification

Act which requires all public work contractors and subcontractors to utilize the Federal

Government’s E-Verify system to ensure that all employees performing work on public work projects are authorized to work in the United States. All Bidders are required to submit a Public

Works Employment Verification Form as a precondition for the contract award.

G. WMDVBE Business. For informational purposes, please describe whether you or your subcontractors are certified Women, Minority, Disabled and/or Veteran Owned Business

Enterprises. Please describe what percentage of your current workforce could be classified as a minority, woman, veteran or disabled person.

NABCEP and the type of certification). Other relevant training, certification, licenses, or memberships should be listed.

Opportunities for apprenticeship or training of new workers and working with educational/training partner (if the project is less than one megawatt they are desired, but not mandatory). The PA Solar Center and the Counties are interested in these projects serving as a training/educational opportunity for the new clean energy workforce, if and where possible. While we recognize the hurdles of training people in the solar industry, particularly when there is no clear path to a job, we are interested to understand, from your perspective, if: your company can build in a solar job training/educational component or possibly a job shadowing experience with these projects; how would you accomplish this, and would you (and how would you) give priority or focus to minority, immigrant, veteran and/or women participants.

I. Compliance with the Inflation Reduction Act provisions: If an individual project is larger than one megawatt, Bidder is required to comply with certain additional provisions of the

Inflation Reduction Act. Describe how you will meet and document the apprenticeship, prevailing wage, and the domestic content requirements as specified in the Inflation Reduction

Act.

J. Tax and Regulatory Status and Clearance Statement. Include a statement attesting to

Bidder’s tax and regulatory compliance with each of the Counties containing projects that you are bidding on.

K. Written indication of PA Solar Center Customer Assistance Contribution. Include

Acknowledgement that a customer assistance contribution will be provided to the PA Solar

Center if a contract is executed. The PA Solar Center research shows that customer acquisition costs for solar developers range from $37/kilowattdc to $50/kilowattdc. The Solar

Center is providing the Bidder with a client who has a confirmed interest in going solar. The

PA Solar Center provides considerable time and resources to work with the client organization to educate and ensure project completion that should save time and money for both Bidder and client. This contribution must be included in the Bid. To maintain impartiality, the PA Solar Center will not accept larger contributions beyond what is specified in this ITB for this project. If a contract is signed with the organization for the solar installation, the Bidder will provide the PA Solar Center the following:

A one-time contribution of $0.025 per contracted watt-dc ($25.00/kilowatt-dc). In fulfillment of this contribution, the following schedule applies:

a. At least twenty percent (20%) 30 days after the organization signs the contract for the solar system.

b. The remainder 30 days after receiving interconnection approval from the utility.

d) Bid Bonds

Bidders must provide bid bonds in the amount of 10% of project costs being bid. All counties in which Bidder is seeking a contract must be named on the Bid Bond along with Montgomery

County.
