Manufacturing is one of the most energy-intensive sectors in Iowa. From running heavy machinery and assembly lines to powering HVAC systems in large facilities, energy bills are often among the top operating expenses. This makes solar energy a particularly powerful tool for manufacturers — not only lowering costs but also improving resilience and supporting long-term growth.
High Energy Use = High Savings Potential
Large-scale manufacturing facilities can consume hundreds of thousands of kilowatt-hours (kWh) every month. With electricity rates continuing to rise, these facilities face escalating operating costs. Solar helps offset a significant portion of that load, allowing manufacturers to lock in predictable energy prices for 25+ years. Even a 500 kW solar system can generate hundreds of thousands of dollars in avoided utility costs over its lifetime.
Tackling Demand Charges
Unlike smaller commercial users, manufacturers often face demand charges — utility fees based on the highest spike in power used during a billing cycle. These charges can make up 30–50% of a facility’s electricity bill. Solar, especially when paired with energy storage, reduces peak demand by generating power during high-use hours. This can dramatically lower demand charges and provide immediate ROI improvements.
Resilience and Reliability
Manufacturing downtime is costly. A few hours without power can mean lost production, missed deadlines, and wasted materials. Solar systems combined with battery storage or backup generation provide energy resilience, allowing facilities to keep critical operations running during outages. In rural parts of Iowa where grid reliability can be an issue, this resilience is a major business advantage.
Real Financial Impact
- Lower Operating Costs: A typical Iowa manufacturer installing a 1 MW system could see $150,000+ in annual energy savings.
- Strong Incentives: Federal tax credits, bonus depreciation, and potential USDA REAP grants can cut upfront project costs nearly in half.
- Fast Payback: With incentives applied, many manufacturing systems pay for themselves in 5–7 years, with decades of free power ahead.
- Multi-Million Dollar Lifetime Savings: Over 25 years, facilities can save $3–5 million or more, depending on energy usage and system size.
Sustainability and Market Advantage
Manufacturers are under growing pressure from customers, partners, and regulators to demonstrate sustainable practices. A solar installation not only cuts costs but also strengthens ESG reporting and supply chain credibility. This can make Iowa manufacturers more competitive when bidding on contracts with sustainability requirements.
Bottom Line
For Iowa manufacturers, solar energy is not just about going green — it’s about gaining a competitive edge. By lowering operating costs, reducing demand charges, and improving resilience, solar can deliver millions in lifetime savings while supporting sustainability goals.
