How to Conduct an RFP for Commercial Energy Supply: A Step-by-Step Guide for Procurement Managers

The difference between an Illinois business that consistently gets competitive electricity and natural gas pricing and one that perpetually overpays often comes down to one thing: whether they conduct a real, structured Request for Proposals (RFP) process or simply accept what their current supplier offers at renewal.

The RFP is the most powerful tool in commercial energy procurement. Done correctly, it creates genuine competition among qualified suppliers, produces multiple comparable bids, and gives you the negotiating leverage to secure market-best pricing and contract terms. Done poorly—or not at all—it leaves significant money on the table year after year.

For procurement managers and operations executives who may be conducting their first formal energy RFP—or who want to improve the results of their existing process—this guide provides a complete, practical framework: from defining your requirements to closing the deal with the best available supplier.

What Is a Commercial Energy RFP and Why Every Procurement Manager Needs One in 2024

The RFP as a Procurement Instrument

A Request for Proposals (RFP) is a formal document that solicits competitive proposals from qualified vendors to fulfill a specific need. In commercial energy procurement, an RFP invites multiple licensed electricity or natural gas suppliers to submit competitive pricing for your supply requirements—creating the market competition that generates best pricing.

The commercial energy RFP serves four critical functions:

1. Creates genuine competition: Multiple suppliers bidding simultaneously creates price competition that a single-supplier negotiation cannot replicate. In Illinois's deregulated market, suppliers know they're competing—and price accordingly.

2. Ensures comparability: A well-structured RFP specifies identical requirements to all suppliers, enabling apples-to-apples comparison of competing bids. Without standardized specifications, suppliers quote different structures that cannot be meaningfully compared.

3. Documents the procurement process: A formal RFP creates a documented record of your procurement decision—important for internal governance, audit purposes, and regulatory compliance.

4. Establishes negotiating leverage: Multiple competitive bids give you factual evidence to negotiate with your preferred supplier. "Supplier A offered $0.067/kWh; can you match or beat that?" is a vastly more effective negotiation than "can you do better?"

Why Energy Procurement Requires a Specialized RFP Approach

Energy procurement RFPs have characteristics that distinguish them from standard procurement:

Market timing matters: Electricity and natural gas prices fluctuate daily. An RFP issued and executed quickly—in a single bidding window—produces comparable pricing. A drawn-out process where suppliers quote on different days produces incomparable results.
Commodity complexity: Energy supply pricing involves multiple components (energy, capacity, transmission, ancillary services) that must be specified and evaluated consistently.
Contract term and structure variation: Suppliers offer different structures (fixed, indexed, block-and-index) that require a framework for equivalent comparison.
Supplier qualification matters: Not all competitive suppliers in Illinois are equally financially stable or service-capable.

Step-by-Step: How to Write a Winning RFP for Commercial Energy Supply That Gets Competitive Bids

Phase 1: Pre-RFP Preparation (2-4 Weeks Before Launch)

Step 1: Gather Account Information

Compile complete information for every facility included in the procurement:

Account numbers (utility account numbers, not supplier account numbers)
Service addresses
Utility tariff rate class for each account
12-24 months of historical consumption data (kWh/month for electricity, therms/month for gas)
Current contract expiration dates
Current supplier and rate information

Request interval (15-minute) demand data from your utility for electricity accounts—this data is essential for demand analysis and enables suppliers to accurately price contracts.

Step 2: Define Your Contract Specifications

Before writing the RFP, define the procurement parameters you want suppliers to bid:

Contract structure options to specify:

All-inclusive fixed rate
Index-based (floating) rate
Block-and-index (percentage fixed, percentage floating)
Hybrid (specify desired mix)

Contract terms to specify:

Desired contract start date (align with current contract expiration)
Contract duration options: request bids for multiple terms (12, 24, 36 months) to enable comparison
Desired effective date for bidding

Service requirements:

Renewable energy content requirements (if applicable)
Green tariff or REC bundling requirements
Any other contractual requirements

Step 3: Identify and Qualify Suppliers

In Illinois, the ICC maintains a list of licensed retail electricity and natural gas suppliers. For a credible competitive bid process, invite 6-10 qualified suppliers. Your commercial energy advisor can maintain the current list of active, financially stable suppliers.

Supplier qualification criteria:

Active Illinois ICC license (verify current status)
Minimum years of operation in Illinois market (2+ years preferred)
Credit standing and financial stability indicators
Service track record in your rate class

Phase 2: RFP Document Preparation

The Core RFP Document Structure

A well-structured commercial energy RFP contains these sections:

Section 1: Introduction and Instructions

Purpose of the RFP
Timeline (issue date, bid due date, evaluation period, contract execution target)
Submission instructions (contact, format, deadline)
Your rights: "The issuing organization reserves the right to reject any or all proposals, to waive any informality, and to select the proposal deemed most advantageous."

Section 2: Account Information

Complete list of accounts with utility account numbers, service addresses, rate classes
Historical consumption data (monthly, 24-month period minimum)
Interval data for demand analysis

Section 3: Bid Specifications Electricity bid specifications example:

"Please provide pricing for the following:

Pricing Type: All-inclusive fixed rate (specify all components included/excluded)
Contract Terms: 12-month, 24-month, and 36-month (provide separate pricing for each)
Start Date: [Date, first day of a billing cycle]
Product: Standard electricity supply (100% standard; no green requirement unless noted)
Capacity: Include PJM capacity in all-in rate; indicate current delivery year capacity assumption
Transmission: Include in all-in rate
Ancillary Services: Include in all-in rate
Taxes and Fees: Specify any taxes/fees NOT included in quoted rate"

Section 4: Contract Terms

Required minimum contract terms (notice provisions, early termination, auto-renewal, assignment)
Bandwidth or usage tolerance requirements (if applicable)
Payment terms

Section 5: Evaluation Criteria State explicitly how bids will be evaluated: "Bids will be evaluated on total delivered cost over the contract term, contract terms and conditions, supplier financial stability, and customer service capabilities."

Section 6: Confidentiality and Process

Confirm that bid information will be kept confidential
Specify that suppliers may not contact other bidders or share their pricing

The Critical Timing Element

Commercial energy RFPs should specify a simultaneous bid window—a specific date and time by which all bids must be submitted, ideally within 2-4 hours for electricity bids (to ensure all bids are priced on the same market day).

Energy prices move daily. If suppliers submit bids on different days, you're comparing quotes priced against different market conditions. A tight simultaneous window ensures genuine comparison.

How to Evaluate Energy Supplier Proposals: Key Metrics, Pricing Structures, and Red Flags to Watch

The Evaluation Framework

Step 1: Verify Responsiveness

Before evaluating pricing, confirm each bid is responsive to your specifications:

Covers all requested accounts
Provides pricing for all requested contract terms
Specifies what is and isn't included in the quoted rate
Is submitted by the deadline

Non-responsive bids should be disqualified.

Step 2: Normalize for Comparison

Create a spreadsheet that calculates total contract cost for each bid, using your historical consumption data:

Total Cost = Quoted Rate ($/kWh) × Annual Consumption (kWh) × Contract Term (years)

For pass-through components (capacity, transmission), use current rates to estimate the total pass-through cost. This creates a total cost basis for comparison—not just a rate comparison.

Step 3: Evaluate Non-Price Factors

Beyond pricing, evaluate:

Factor	Questions to Ask
Contract terms	What are early termination provisions? Auto-renewal terms?
Capacity treatment	Is capacity all-in or passed through? What delivery year is assumed?
Bandwidth/usage tolerance	What happens if my consumption exceeds/falls below a threshold?
Green energy	What RECs are included? From what registry and vintage?
Customer service	What is the dispute resolution process? Account management structure?
Supplier stability	How long has this supplier operated in Illinois?

Red Flags in Supplier Proposals

Unusually low rates: Significantly below all other bids may indicate capacity is excluded, the supplier is financially stressed, or terms are unfavorable in non-obvious ways
Vague pass-through language: "Capacity charges may be adjusted to reflect market costs"—without specific calculation methodology, creates unlimited cost exposure
Short or no auto-renewal notice: Auto-renewal traps with 30-day notice windows are a common and costly contract trap
Broad force majeure: Language that allows the supplier to terminate or re-price without your consent in broadly defined circumstances
Non-standard early termination: Fees calculated as "entire remaining contract value" rather than reasonable market-based liquidated damages

Closing the Deal: How to Select the Best Commercial Energy Supplier and Maximize Long-Term Savings

Selecting the Winning Bid

After evaluation, you'll typically have 2-3 finalists. Before selecting:

Use the RFP results as negotiating leverage: Share (with appropriate confidentiality protections) that you have competing bids, and give your preferred supplier an opportunity to sharpen their pricing. Often, 15 minutes of negotiation after bid review can extract an additional $0.002-$0.005/kWh improvement.

Verify financial stability: For the selected supplier, request a reference to their clearing bank or financial institution, review any publicly available credit information, and confirm active ICC licensure.

Negotiate critical contract terms: Before finalizing, negotiate any contract terms that don't meet your requirements. Key negotiating points:

Extended auto-renewal notice period (90 days preferred, not 30)
Reasonable early termination definition and calculation method
Clear capacity treatment specification
Green energy documentation requirements

Document your selection rationale: Create a written record of the bid evaluation, comparison, and selection rationale—essential for governance, procurement policy compliance, and audit purposes.

Post-Contract Management

After execution:

Set calendar reminders 90-120 days before contract expiration for the next RFP
Implement bill verification against contracted rates for the first 3 billing cycles
Establish a single point of contact with the supplier for account management
Track annual consumption against contracted assumptions to monitor for bandwidth clause exposure

Conclusion: The RFP Process Is Your Most Powerful Energy Cost Reduction Tool

For Illinois commercial businesses, the energy RFP process is not a bureaucratic formality—it's the mechanism that creates genuine market competition and drives pricing to its lowest sustainable level. Businesses that conduct structured RFPs consistently achieve 8-20% better pricing than those that simply renew with their current supplier, compounding to tens or hundreds of thousands of dollars in savings over multiple contract cycles.

The investment required is modest: 4-6 hours of preparation for a well-structured RFP, 2-4 hours of evaluation, and an hour of negotiation. The return on that investment—typically $20,000 to $200,000+ in annual savings for mid-to-large commercial facilities—represents one of the highest ROI activities any procurement manager can undertake.

Frequently Asked Questions

What is a commercial energy RFP?

A commercial energy RFP (Request for Proposals) is a formal document soliciting competitive pricing from multiple licensed electricity or natural gas suppliers for your facility's supply requirements. It creates genuine market competition, enables apples-to-apples bid comparison, and typically achieves 8-20% better pricing than renewing with a single supplier.

How many suppliers should be included in a commercial energy RFP?

For a credible competitive process, include 6-10 qualified, licensed suppliers. Fewer than 5 suppliers limits competitive pressure; more than 12 creates administrative burden without proportional benefit. An energy broker or advisor can identify and pre-qualify suppliers appropriate for your rate class and consumption level.

How long should a commercial energy RFP process take?

A well-executed energy RFP can be completed in 2-3 weeks from initial preparation to contract execution: 1-2 weeks for preparation and supplier identification, 1-2 days for the bid window, 3-5 days for evaluation and negotiation, and 1-2 days for contract execution. Starting 90-120 days before your current contract expiration provides adequate time for a thorough process.

What information do I need to include in a commercial energy RFP?

Essential information includes: utility account numbers for all facilities, service addresses and rate classes, 12-24 months of consumption data, current contract expiration dates, desired contract terms (duration, structure, start date), and any specific requirements (renewable energy, pass-through treatment, bandwidth provisions).

What are the red flags in commercial energy supplier proposals?

Key red flags include: rates significantly below all competitors (may indicate excluded components), vague or unlimited pass-through provisions, short auto-renewal notice windows (less than 60 days), broad force majeure language allowing supplier re-pricing, and early termination fees calculated as the full remaining contract value.

Can a commercial energy broker conduct the RFP process for my business?

Yes—experienced commercial energy brokers or advisors can manage the entire RFP process, including preparing specifications, identifying suppliers, managing the bid window, evaluating proposals, and supporting negotiations. Most are compensated by the winning supplier, making the service free to your business. Verify the broker's transparency and process integrity before engagement (see our energy broker compensation guide).
