Commercial Electricity for Churches and Faith-Based Organizations in Texas

Energy strategy for Texas churches and faith-based organizations

Churches sit in an unusual spot in the commercial electricity market. Weekly usage is dominated by Sunday morning service plus midweek programming, which creates concentrated demand peaks with long idle periods in between. Load factor is among the lowest of any commercial category, which affects both the right contract structure and the right supplier shortlist. Most Texas 501(c)(3) churches also qualify for sales tax exemption on commercial electricity, which is a straightforward paperwork item that too many congregations never file.

This guide covers how church electricity load actually behaves, how multi-campus and multi-site ministries use portfolio leverage, how the sales tax exemption works, and how Electric Decisions runs a documented procurement built around church operations. Built for independent congregations, denominational churches, multi-campus ministries, Christian schools, and faith-based nonprofits across Texas.

How churches use electricity

Church load is concentrated by day of week and by season in a way that few other commercial categories match.

Sunday service drives the single biggest demand peak of the week. The sanctuary HVAC system runs harder than any other hour because it has to cool a packed room full of people, often in Texas summer heat. Lighting runs at full output. AV and sound systems draw their peak load. The nursery, children's wings, and classrooms all run. For a typical mid-size church, Sunday morning accounts for a large share of the week's electricity consumption in just a few hours.

Midweek programming adds Wednesday evening services, Bible studies, youth group, choir rehearsal, and administrative work. The load is modest but regular.

Weekday operations include church office staff, mother's day out or preschool programs (common at larger churches), counseling appointments, and facility rentals. For churches with attached Christian schools or daycare, weekday load becomes a major share of the bill.

Baseline load includes exterior and parking lot lighting (24/7), security systems, refrigeration in the kitchen or fellowship hall, and HVAC setback levels on non-service days.

Special events (weddings, funerals, revivals, holiday services) create occasional additional load spikes.

Load factor sits in a low range for most churches because of the Sunday-peak-plus-idle pattern. This is among the lowest in any commercial category.

The Texas sales tax exemption for 501(c)(3) churches

Texas Tax Code Section 151.310 exempts qualifying nonprofit religious organizations from state sales tax on purchases, including commercial electricity. A properly filed exemption is a meaningful share of the total electricity bill, often larger than any rate negotiation win.

The process:

• The church must have a 501(c)(3) determination letter from the IRS.
• The church files a Texas Application for Exemption with the Comptroller.
• Once approved, the church provides the exemption certificate to its retail electricity provider.
• The REP applies the exemption going forward.

Many churches qualify but have never filed. Some filed years ago, changed REPs, and never re-filed the exemption with the new REP. Both situations leave money on the table. Churches with attached preschools, daycare operations, or facility rental businesses should check with their tax advisor whether the exemption still applies to the full bill or needs to be apportioned.

Electric Decisions handles the exemption paperwork as part of the procurement process when applicable.

Contract decisions that move the number

Three decisions do most of the work on a church electricity contract.

Term length: Most Texas churches land on 24 or 36 month fixed-rate terms. Budget predictability is often more important than squeezing the last fraction of a cent, since church budgets run on fiscal year cycles with limited discretionary flex.

What is actually fixed: A fixed-rate contract often lets delivery charges, regulatory pass-throughs, and (where applicable) supply-side demand charges float. For churches, the delivery and regulatory pieces matter proportionally more than for other commercial categories because of the low load factor.

Bandwidth: Your contract assumes a usage range. Growth in attendance, adding a Christian school, launching new programming, or expanding the campus all change usage.

Multi-campus ministries and denominational groups have real leverage

Multi-campus churches, denominational conferences, and faith-based nonprofit networks have a procurement advantage that single-congregation churches do not: aggregated load.

Suppliers price a combined portfolio more aggressively because the volume is easier to hedge. For denominations managing dozens or hundreds of churches, the total savings can fund real ministry.

Coordination questions:

Autonomy and local decision-making: Many denominations preserve local congregation autonomy on administrative decisions. Portfolio procurement can be structured as an opt-in offer, not a mandate.

Renewal cohorts: Larger portfolios typically stagger renewals.

TDU zone coverage: Statewide ministries span multiple utility zones. The Texas Retail Electric Providers directory lists which suppliers actively bid each zone.

Nonprofit paperwork: Each participating entity needs its own 501(c)(3) and sales tax exemption on file.

Where your church sits

Texas has four investor-owned TDUs plus municipal utilities. Oncor covers North Texas, CenterPoint covers Greater Houston, AEP Texas covers South and West Texas, and TNMP covers non-contiguous zones. Austin Energy and CPS Energy are municipal utilities that do not allow retail choice. Churches inside Austin or San Antonio city limits buy under the utility's tariff. See all Texas cities for coverage detail.

Where churches overpay

Not filing the sales tax exemption. This is the single largest avoidable overpayment for most Texas churches.

Letting the contract roll to month-to-month. Holdover rates run well above market.

Comparing only cents per kWh. Delivery charges and demand charges run higher as a share of a church bill than for other commercial categories because of the low load factor.

Overlooking demand charges on Sunday peaks. For a church with a large sanctuary and HVAC that cycles hard during service, demand charges can be a meaningful share of the bill. Pre-cooling the sanctuary before service (shifting the HVAC load earlier) can reduce the demand peak modestly.

Treating all buildings on a campus the same. A church with a sanctuary, education building, and Christian school has three different load profiles. Submetering and separate accounts (where appropriate) can give better pricing visibility.

Timing the renewal

Start before contract expiry. Three to six months of runway is enough for most churches. For a multi-campus ministry or a church with an attached school, six to nine months is safer.

The single most avoidable mistake is starting in the final 30 days.

How Electric Decisions runs a church procurement

Five documented steps. Same process on a small congregation, same process on a 50-campus denomination.

Step 1: Intake: We pull your last 12 months of usage from the TDU through a Letter of Authorization. We also check whether the sales tax exemption is on file and applied correctly.

Step 2: Reference: We benchmark your current all-in cost against the live ERCOT forward curve.

Step 3: Competition: We run an identical-specs RFP against the suppliers who bid your zone competitively.

Step 4: Contract: We red-line the paperwork in plain English. ETF, bandwidth, material change clause, pass-through caps, holdover language, and the sales tax exemption treatment.

Step 5: Execution: We manage the switch and watch the market through your term.
