The Texas Dairy Industry’s Renewable Energy Potential
Texas has sun, wind and a lot of manure, so renewable energy comes up often at dairy meetings. This guide explains the options and the questions to ask before spending money.
What counts as renewable energy on a dairy?
The common options are solar panels, wind turbines and biogas systems that capture methane from manure. Some dairies also look at energy efficiency upgrades, which often pay back faster than new generation.
Figures about potential in the headline are as reported and should be checked at the source. Start with the energy pages at USDA and the Rural Development office for program information.
The word potential can mean technical potential, economic potential or what is realistic for a particular farm. The answers differ a lot, so ask which one a report means.
Be skeptical of any number that does not say how it was calculated or what assumptions about prices and rules it relied on.
Start with efficiency
Before you generate power, reduce what you use. Efficient lighting, variable speed vacuum pumps, plate coolers and heat recovery cut bills with modest investment. Many electric utilities and programs offer audits.
Look at your monthly electric bills by season, since milking and cooling load vary. That tells you where savings are largest.
Even small steps count. Switching lights, fixing leaks in compressed air or vacuum lines and adjusting cooling schedules can trim a bill without any new technology.
A few hours with a certified auditor can turn up quick wins that you have walked past for years.
- Review utility bills for demand charges
- Check lighting, pumps and cooling equipment
- Ask about energy audits
- Prioritize quick payback items
Solar and wind questions
Solar can offset daytime loads, and Texas has strong sun, but the economics depend on rates, net metering rules, tax treatment and financing. Wind needs good wind at hub height and zoning approval.
Ask installers for references from dairies, written production estimates and details on warranties and maintenance. Get at least three quotes, and check state and local requirements.
Net metering and utility interconnection rules vary by utility, and in some areas by cooperative or municipal provider. Ask your utility in writing how excess power is credited and what fees apply.
Wind is often a better fit on the Panhandle and High Plains than elsewhere, while solar works across most of the state, so location matters.
Biogas and manure
Biogas systems turn manure into gas that can fuel generators or be upgraded for other uses. They are complex, capital-intensive and need steady operation, and results depend on herd size and manure handling.
NRCS and TCEQ can explain conservation and permit issues. Ask what happens to digestate and how odor and nutrients are handled.
Digesters also raise questions about who owns the gas and environmental credits. Read any contract carefully and have an attorney review it.
Parts of Texas are far from a gas pipeline or a utility connection that accepts power, which can decide whether a project makes any sense.
Paying for it
Costs, incentives and tax credits change, so verify each one at its official source. Federal and state programs may support some projects, and lenders such as Farm Credit finance energy upgrades. The IRS publishes tax guidance.
Talk to your accountant before assuming a credit applies. General education here is not tax advice. The farm money guide walks through payback calculations.
Ask whether a project will change your property tax, insurance or lease terms, since those add real costs that early estimates skip.
Risks and trade-offs
Equipment can underperform, prices can shift and rules can change. A project that pencils out on paper may stumble if the herd shrinks or interest rates rise. Use conservative assumptions and test a bad case.
Think about land use, neighbors and maintenance too. A system that nobody on the farm has time to look after will not deliver what the sales sheet promised.
Check whether any local zoning or permit rules apply before you buy equipment, since delays can add costs.
Next steps for dairies near Stephenville and beyond
Begin with an energy audit, set a payback target and get quotes. Visit a dairy that already runs a system if you can. Your AgriLife Extension contacts may know of examples.
Over at farm.FM the dairy page and farming section cover energy and farm life, including a farm.FM story on dairy renewable energy. The tractor and equipment guide also touches on fuel use.
Share what you learn with other dairies. Honest accounts of what worked and what did not are the most valuable resource of all.
