A. PURPOSE

Energy Northwest will utilize the following guidelines in the selection of Bidders.

1. The purpose of the selection will constitute an objective and impartial procedure in that all interested Bidders are evaluated against the same criteria.

2. The criteria utilized in evaluating prospective Bidders shall relate to the competence and qualifications of the Bidders being considered so that the Bidders selected shall constitute the best qualified of those considered in the sole judgment of Energy

3. The procedures employed shall ensure that companies owned by women and minorities are provided with full and equitable opportunity for participation in the selection process.

B. PROCEDURE

1. Energy Northwest shall publish in a newspaper of statewide and/or local circulation an announcement inviting all interested Bidders to indicate their interest in submitting a proposal for the Work described in the RFP. The announcement will state a date by which proposals and supporting documentation must be received.

a. RFP Questions and Responses: This is an opportunity to seek clarification or information regarding the requirements of this RFP. Submit questions via email to the Procurement Specialist no later than 1:00pm (Local Time Richland, WA) on December 8, 2026. Questions after this date will not receive a response. The Procurement Specialist will provide answers to the questions via an Addendum to all Bidders.

b. Proposal Due Date: Submit proposals to the Procurement Specialist no later than 1:00pm (Local Time Richland, WA) on December 17, 2026, Proposals shall be submitted by email to slund@energy-northwest.com.

2. Proposals received by the stated due date and time will undergo a structured, multi-phase evaluation conducted by Energy Northwest. Each proposal will be evaluated against predefined criteria using a pass/rejection methodology and a quantitative, weighted scoring model. Bidders must provide sufficient detail in their submissions to allow evaluators to accurately assess, based on the methodology below, Bidder’s overall responsiveness in areas of technical knowledge, experience, management, staff and schedule as outlined in RFP Section II.

a. Mandatory qualifications will be evaluated on a pass/rejection basis. Failure to meet any mandatory requirement will result in automatic rejection of the proposal.

mailto:sjackson@energy-northwest.com

b. Commercial qualifications will be evaluated on a yes/no basis. Consistent with scoring methodology, a “yes” response will receive three points and a “no” response will receive one point.

c. Technical qualifications reflect factors other than price, as authorized under

RCW §43.52.565. Evaluators will assign a raw score from 0 to 5 for each technical evaluation criterion. Scores will reflect the demonstrated quality, completeness, clarity, and responsiveness of Bidder’s proposal to the requirements outlined in RFP Section II.

i. Score of 5 – Significantly exceeds requirements outlined; with superior, verifiable value; minimal risk; compelling differentiators and outcomes (e.g., proven results, innovative yet feasible approach, quantified benefits, exceptional references, robust risk mitigation, high quality experience). If pricing is related, this score may be used to differentiate Bidders as determined by Energy Northwest.

ii. Score of 4 – Exceeds requirements outlined; presents clear, credible solutions; lower risk; well-documented, tailored approach (e.g., strong methodology, strong risk mitigation, relevant experience, measurable performance commitments). If pricing is related, this score may be used to differentiate Bidders as determined by Energy

iii. Score of 3 – Meets minimum requirements with adequate detail;

manageable risk; demonstrates reasonable understanding; may lack differentiators (e.g., clear plan, standard approach, baseline compliance, typical references, limited innovation). If pricing is related, this score may be used to differentiate Bidders as determined by Energy Northwest.

iv. Score of 2 – Marginal response; some requirements addressed but with notable gaps; moderate to high risk; limited detail; questionable feasibility without clarification. If pricing is related, this score may be used to differentiate Bidders as determined by Energy Northwest.

v. Score of 1 – Deficient response; major deficiencies resulting in low probability of successful performance; vague plan; significant misalignment with scope; failure to address critical risks. If pricing is related, this score may be used to differentiate Bidders as determined by Energy Northwest.

vi. Score of 0 – Does not meet requirements. Proposal may be considered unresponsive and not eligible for award consideration based on this criterion (e.g., missing required sections, failure to submit required forms, excessive or unacceptable exceptions).

d. Weighted Scoring Calculation. Each technical criterion is assigned a weighting factor expressed as a percentage of the total available points. For each criterion, the raw score (0–5) assigned by evaluators will be multiplied by the applicable weighting factor to produce the criterion’s weighted score.

The sum of all weighted scores will constitute the Bidder’s total technical score used to determine ranking and competitive range.

Score Formula: Raw Score (0–5) × Criterion Weight = Weighted Score

e. Evaluator Criteria. Energy Northwest will evaluate proposals using the weighted criteria listed below. Bidders are responsible for providing comprehensive, detailed responses for each criterion to ensure accurate scoring and full consideration.

Evaluation Criteria Weighted Average%

General Qualifications 10%

Commercial Qualifications 10%

Technical Qualifications 45%

Price 35%

3. Based on the proposals submitted and evaluated, Energy Northwest may elect to perform Bidder interviews. All Bidders which have submitted a proposal that are deemed to be responsible will be provided with an opportunity for an interview.

Interviews may be held remotely, or in person at the sole discretion of Energy Northwest. Bidders will receive more information regarding how to prepare for the interview if selected to participate.

4. After completion of the interviews, Energy Northwest may either choose the Bidder deemed to be qualified, responsive, responsible, and most advantageous to perform the required Work or Energy Northwest may provide an opportunity for Bidders to submit a Best and Final Offer (BAFO).

5. After the submittal of a BAFO, if requested, there will be no further opportunity for clarification, refinement, and/or discussions. Energy Northwest will review and evaluate the BAFOs. Energy Northwest will select the Bidder whose proposal is in the best interest of and most advantageous for Energy Northwest if any.

6. Bidder shall thoroughly examine and be familiar with the BAFO documents. Submittal of a BAFO shall constitute an acknowledgement upon which Energy Northwest may rely that the Bidder has thoroughly examined and is familiar with these documents. Failure or neglect to receive or examine these documents shall in no way relieve Bidder from any obligation with respect to the proposal or these documents. No claim for additional compensation will be allowed, which is based on lack of knowledge of the BAFO documents.

7. Energy Northwest reserves the right, without qualification, to select any BAFO as a basis for negotiation, to reject all BAFO’s and to exercise its discretion and apply its judgment with respect to any BAFO submitted. This BAFO does not commit Energy Northwest to pay any costs incurred in connection with any BAFO, or to contract for any Work. There is no commitment on the part of Energy Northwest to accept the lowest priced BAFO or any conditions imposed by a contractor as a requirement of acceptance of their BAFO. The BAFO to be accepted shall be at the sole discretion of Energy Northwest.

8. Information submitted to Energy Northwest in response to this BAFO becomes public record under the Revised Code of Washington.

iii. After Bid opening, only Bidders that submitted a Bid, subcontractors, or others that can show a substantial economic interest in the Bid award and who are aggrieved, are eligible to protest. After Bid opening, protests are limited to issues related to Bid opening, evaluation of the Bids, and intention to award decisions, and are further limited to those items that were not known or could not have been reasonably known prior to Bid opening. Such issues that were known or should have reasonably been known must have been protested prior to Bid opening and are no longer eligible as an issue of protest.

Only protests stipulating an issue of fact concerning the following subjects shall be considered:

▪ A matter of bias, discrimination or conflict of interest on the part of the evaluator;

▪ Errors in computing the score or Bid Price upon which award decisions are based; or

▪ Non-compliance with procedures described in the solicitation for the opening and award itself.

or

2. Find only minor technical or harmless errors in Energy Northwest’s acquisition process and determine Energy Northwest to be in substantial compliance and therefore reject the protest; or

3. Find merit in the protest and pursue correction including correcting the errors and reevaluating the Bids, and/or reissuing the solicitation to begin a new process; or
