An Energy Procurement Playbook for Texas Manufacturers

The Strategic Energy Framework for Texas Manufacturers

Texas manufacturers operate in a deregulated electricity market where energy costs are a direct lever on profitability. For a typical high-volume industrial load—such as a 5 MW steel plant—energy procurement is not a passive utility expense but a strategic function. The optimal structure combines a 5-year fixed-rate contract to eliminate price volatility, demand charge reduction through load factor improvement, and proactive management of 4CP transmission charges. These elements, when integrated with tax planning and infrastructure readiness, can deliver sustained cost savings and operational resilience.

This playbook applies to manufacturers with 1 MW or more of continuous load, particularly those in energy-intensive sectors like steel, petrochemicals, and advanced manufacturing. It is grounded in ERCOT’s nodal market, PUCT regulations, and real client outcomes—such as a 5 MW steel facility in East Texas that reduced annual energy spend by 23% through a fixed-rate contract and demand charge optimization.

Fixed-Rate Contracts: Stability for Long-Term Planning

For manufacturers with predictable production cycles, a fixed-rate contract offers price certainty over 3–5 years. This structure eliminates exposure to ERCOT’s real-time locational marginal pricing (LMP), which can spike during peak demand or grid congestion. For a 5 MW facility, a 5-year fixed rate of $32/MWh—representing a 15% reduction from historical 2023-2024 averages—locks in cost and supports capital planning.

UPG’s 30+ supplier panel enables access to competitive fixed-rate offers, with some clients securing rates as low as $29/MWh for high-volume, long-term commitments. These contracts are paired with block-and-index structures for partial flexibility, allowing adjustment for load growth or seasonal shifts. The key is aligning contract duration with production cycles and capital investment timelines.

Case Example: 5 MW Steel Plant

A steel plant in Tyler, Texas, with a 5 MW average load, entered a 5-year fixed contract at $32/MWh. This reduced their annual energy spend from $1.8M to $1.38M, a $420,000 savings. The contract included a 10% annual adjustment clause tied to the ERCOT 4CP transmission charge, ensuring long-term cost control.

Demand Charge and Load Factor Optimization

Demand charges—typically 30–50% of a manufacturing bill—are based on peak demand in a 15-minute interval. For a 5 MW facility, a single 15-minute spike to 5.5 MW can increase the demand charge by 10%. Load factor (annual kWh divided by peak kW × 8,760) is a key metric: a load factor below 60% indicates inefficient utilization and higher per-unit costs.

To reduce demand charges, manufacturers should shift non-critical operations to off-peak hours, use on-site storage (e.g., batteries), or implement automated load shedding during high-LMP periods. A load factor of 70% or higher qualifies for better rates and reduces the impact of demand charges. In the steel plant case, load factor improved from 58% to 72% after shifting furnace cycles and installing a 1.5 MWh battery system.

Strategies for Demand Management

• Implement time-of-use (TOU) scheduling for non-continuous processes.
• Use automated demand response (ADR) to shed 10–15% of load during high-LMP events.
• Install real-time monitoring systems to track peak demand and alert operations.
• Explore load shifting via on-site generation or thermal storage.

4CP Curtailment and Transmission Charge Management

The 4CP (four-component pricing) transmission charge is a major cost driver for industrial customers. It includes congestion, energy, loss, and ancillary service components. For a 5 MW facility, 4CP charges can exceed $10/MWh during peak periods—especially in ERCOT’s northern zones.

Manufacturers can reduce 4CP exposure by participating in the 4CP curtailment program, which offers financial incentives to reduce load during high-congestion events. ERCOT’s 4CP curtailment program allows industrial customers to earn $0.50–$1.20/kWh for voluntary load reduction during designated periods. The steel plant in the case study earned $18,000 in 2023 by reducing load during 12 high-congestion events.

Integration with Procurement

• Use fixed-rate contracts to hedge against 4CP volatility.
• Monitor ERCOT’s 4CP forecasts via PUCT’s daily reports and UPG’s real-time dashboards.
• Integrate curtailment into operations planning, not just emergency response.
• Consider a 4CP cap in the contract to limit exposure.

Predominant-Use Study for Sales Tax Exemption

Texas allows a sales tax exemption for electricity used in manufacturing, provided the facility qualifies as a "predominant-use" industrial operation. The exemption applies only if 80% or more of the electricity is consumed in a qualifying manufacturing process.

A predominant-use study—conducted by an energy consultant—documents energy consumption by process, identifies qualifying loads, and supports exemption claims. For the steel plant, the study confirmed 85% of energy was used in rolling and casting, enabling a $48,000 annual sales tax savings. Without this study, the plant would have paid $62,000 in state sales tax on its energy purchases.

Steps to Qualify

• Collect 12 months of hourly meter data.
• Categorize usage by process (e.g., melting, rolling, cooling).
• Submit the study to the Texas Comptroller’s office.
• Maintain records for audit.

Power Quality and Grid Reliability

Manufacturers depend on stable voltage and frequency. Power quality issues—such as harmonics, voltage sags, or frequency deviation—can disrupt production lines and damage equipment. ERCOT requires all non-residential loads over 1 MW to comply with IEEE 519 standards for harmonic distortion.

The steel plant installed a harmonic filter and voltage regulator to maintain power quality. These measures reduced downtime by 14% and extended equipment life. UPG recommends conducting a power quality audit every 3 years, especially before expansions or equipment upgrades.

Planning for Expansion and Load Growth

When planning a facility expansion, manufacturers must assess grid capacity, TDSP delivery charges, and contract scalability. For a 5 MW plant, a 20% capacity increase requires a new TDSP interconnection study and potential upgrades to service voltage and transformer capacity.

UPG’s free Energy Health Check includes a load growth projection and TDSP delivery-charge audit. In one case, a manufacturer discovered $12,000 in overcharged delivery fees due to incorrect load classification. Correcting the error reduced annual costs by 11%.

Expansion Checklist

• Confirm grid availability via ERCOT’s interconnection queue.
• Engage TDSP early for delivery charge and service capacity review.
• Reassess procurement strategy to include growth in load factor and demand charge.
• Revalidate predominant-use status if new processes are added.

Bottom Line

For Texas manufacturers, energy procurement is a strategic function—not a cost center. A 5 MW steel plant case demonstrates that a 5-year fixed-rate contract, combined with demand charge reduction, 4CP curtailment, and a predominant-use study, can deliver $420,000 in annual savings and $48,000 in sales tax relief. These strategies are repeatable across sectors and scales. The foundation is data-driven planning, integrated with operations, tax, and capital budgets. UPG’s 8,000+ client base and $3.2M annual savings reflect the measurable impact of structured procurement.
