Energy Procurement for Manufacturing Facilities: A Practical Guide

Manufacturing facilities are among the most energy-intensive commercial operations in the United States. Electricity and natural gas are not discretionary expenses for a manufacturer — they're operational inputs as fundamental as raw materials and labor. Yet most manufacturing businesses approach energy procurement with far less rigor than they apply to sourcing those other inputs.

This guide covers the unique energy procurement considerations for manufacturing operations and the strategies that can meaningfully reduce one of your largest operating costs.

Why Manufacturing Energy Procurement Is Different

Manufacturing facilities have energy characteristics that distinguish them from typical commercial buyers:

• High and relatively stable load: Manufacturing operations typically run consistent production schedules, creating predictable and often 24/7 energy demand profiles.
• Large absolute spend: Even moderately-sized manufacturing facilities often have electricity bills of $50,000–$500,000 per month or more. Small percentage improvements translate to significant dollar savings.
• Both electricity and natural gas: Many manufacturing processes use both fuels — electricity for motors, lighting, and HVAC; natural gas for heating, process heat, and steam generation.
• Multiple rate classifications: Large manufacturers may qualify for industrial rate schedules that have different pricing structures than standard commercial rates.
• Demand charges: Manufacturing facilities with large motor loads or equipment that creates demand spikes can face significant demand charges on their electricity bills — charges that competitive procurement alone may not fully address.

Understanding Demand Charges in Manufacturing

Demand charges are one of the most significant and least understood components of a manufacturing electricity bill. Unlike consumption charges (based on total kWh used), demand charges are based on your peak power draw during a defined measurement interval — typically the highest 15-minute interval during the billing period.

For manufacturing facilities with heavy equipment, this can be substantial. A facility that starts multiple large motors simultaneously — even briefly — can set a peak demand that drives high demand charges for the entire month.

Demand charges are typically set by the utility and cannot be changed through supplier selection. However, understanding them is critical to evaluating your total energy cost and identifying operational opportunities to reduce peak demand.

Natural Gas in Manufacturing Operations

Natural gas serves critical functions in many manufacturing operations — process heating, steam generation, direct-fired equipment, and space heating. For energy-intensive manufacturers, gas procurement deserves the same attention as electricity.

Interruptible vs. Firm Service

Large industrial natural gas buyers often have the option to take interruptible service — where the utility can curtail your gas supply during high-demand periods — in exchange for a lower base rate. Manufacturers that can manage interruptions (with backup fuel capability or flexible production schedules) may benefit from interruptible service rates.

Firm service guarantees uninterrupted supply at a higher base rate. For manufacturers where a gas interruption would halt production or create safety issues, firm service is the appropriate choice regardless of cost.

Load Factor Considerations

Natural gas pricing for industrial buyers often reflects load factor — the ratio of your average daily usage to your peak daily usage. A manufacturer with highly consistent daily consumption (high load factor) typically receives better pricing than one with highly variable consumption (low load factor).

Electricity Rate Structures for Manufacturers

Time-of-Use (TOU) Considerations

In deregulated markets, some commercial supply products include time-of-use pricing — where rates vary by time of day and/or day of week. For manufacturers with flexible production schedules, TOU products can provide significant savings by shifting energy-intensive operations to off-peak hours.

Fixed vs. Variable for Large Industrial Buyers

The case for fixed-price electricity contracts is particularly strong for manufacturers. Your energy cost is a direct input to your product cost — unpredictable energy pricing makes it harder to accurately price your products and manage margins. Fixed-price contracts convert a variable input cost into a predictable one, which has real value beyond just the average rate.

Multi-Year Contracts

Large manufacturing facilities are often strong candidates for multi-year fixed-price contracts. Suppliers value large, stable loads and may offer better pricing for longer commitments. A 2–3 year fixed-price contract at favorable rates can lock in a competitive cost advantage for an extended period.

The Procurement Process for Manufacturing Facilities

Bill and Usage Analysis

Effective manufacturing energy procurement starts with a thorough analysis of your current bills and usage data. This includes:

• Historical usage (kWh or therms) by month
• Peak demand history (kW) by month
• Current rate schedule classification
• Breakdown of all bill components (supply, delivery, demand, taxes)
• Contract status and expiration date

Load Profile Analysis

For large facilities, interval data (15-minute or hourly usage readings) can reveal usage patterns that affect both pricing and optimal rate structure selection. Suppliers increasingly use interval data to price large commercial accounts more precisely.

Competitive Bid Process

Running a competitive bid for a manufacturing facility follows the same process as smaller commercial accounts — but the stakes are higher. A 5% improvement in supply rate on a $500,000 annual electricity bill is $25,000 in savings. The value of running a thorough competitive process is proportionally larger.

Supplier Evaluation Beyond Price

For large manufacturing accounts, supplier stability and financial strength matter more than for smaller commercial buyers. A supplier that fails during the contract term creates significant disruption. Evaluate suppliers on financial strength and operational track record, not just the lowest bid.

Multi-Site Manufacturing Operations

For manufacturers operating multiple facilities across one or more states, coordinated energy procurement can deliver benefits beyond what individual site negotiations achieve:

• Portfolio pricing: Some suppliers will aggregate multiple sites into a single contract, potentially offering better pricing due to combined volume.
• Simplified management: A single supplier relationship and contract structure reduces administrative complexity.
• Coordinated renewals: Aligning contract end dates across sites simplifies the renewal process and creates leverage in negotiations.

What Hovey Energy's In-House Team Can Do for Manufacturers

Manufacturing energy procurement is not a one-size-fits-all exercise. The complexity of large industrial accounts — demand charges, interruptible service options, load profile analysis, multi-year contract structures — requires an experienced team that understands industrial energy use.

Hovey Energy's in-house team has worked with manufacturing clients across Texas, the Midwest, and the Mid-Atlantic since 2012. We've handled accounts ranging from smaller fabrication shops to large industrial facilities with seven-figure annual energy spend.

Our process starts with a thorough analysis of your current situation — bills, usage, contract status, and rate classification. We then run a competitive bid process tailored to your facility's load profile and needs, and present options in plain language that your operations and finance teams can evaluate.

If energy is a significant cost line in your manufacturing operation, a free analysis with our team is worth 30 minutes of your time. We'll tell you exactly where you stand and what's available in your market.
