Texas Diocese & Multi-Parish Electricity Procurement: A Guide for Catholic Business Managers

Why Diocesan Electricity Procurement Is a Different Problem Than a Single Church's

‍

Most guidance written for Texas churches on commercial electricity assumes a single congregation, one building, one Sunday service schedule, and one person — a pastor, a business administrator — making the decision. That model works for an independent Baptist or non-denominational congregation. It does not describe how a Catholic diocese buys electricity.

‍

A Texas diocese overseeing a dozen, forty, or more than a hundred parishes is a fundamentally different kind of buyer. The parishes span multiple TDU territories, multiple cities, and — critically — multiple regulatory zones, some open to competitive supplier choice and some not. Contracts expire on different dates because each parish historically shopped, or didn't shop, on its own. Physical footprints vary wildly: a rural parish with a single small meter looks nothing like a downtown cathedral parish with a school, a rectory, a parish hall, and a cemetery office all drawing power separately. Centralizing procurement across a portfolio like this is a genuinely different exercise than helping one congregation switch providers, and it rewards a different strategy.

‍

This guide covers how Texas dioceses and multi-parish Catholic systems can approach electricity procurement at the portfolio level — what changes, what stays the same, and where the real savings opportunity sits when you're managing this decision across many locations instead of one.

‍

The Same Deregulated Market, a Very Different Buyer

‍

Every parish account in ERCOT's deregulated footprint — roughly 85% of the state, covering most of Dallas-Fort Worth, Houston, and dozens of other Texas markets — participates in the same competitive commercial electricity market as any other Texas church or religious organization. A parish selects a retail electricity provider (REP) for the energy supply portion of its bill; the local TDU — Oncor, CenterPoint Energy, or AEP Texas, depending on location — continues to own the wires and deliver power regardless of which REP is chosen. Current commercial energy-only rates run roughly 7–9¢/kWh for a competitively bid fixed contract, with delivery charges added on top and set by the TDU, not negotiable by provider.

‍

What changes at the diocesan level isn't the market mechanics — it's the leverage. A single parish auctioning 15,000 kWh/month is one small account among thousands a provider is bidding on. A diocese presenting twelve, thirty, or eighty parish accounts as a combined portfolio is a materially larger piece of business, and providers price larger, consolidated accounts more aggressively than they price the same total volume spread across many independent shopping events.

‍

Portfolio Aggregation: Why a Dozen Parishes Are Worth More Than a Dozen Separate Quotes

‍

The most common pattern in a diocese that hasn't centralized its electricity procurement is exactly what you'd expect: each parish's contract renewed — or lapsed onto a holdover rate — on its own schedule, negotiated, if negotiated at all, by whoever happened to be handling that parish's operations at the time. The result is a portfolio of parish accounts on wildly different rates, different contract terms, and different expiration dates, with no one holding a full picture of the diocese's total electricity spend.

‍

Aggregating that portfolio into a single competitive procurement event changes the economics in two ways. First, combined volume attracts more aggressive bids — a provider competing for a diocese's full parish portfolio has more revenue on the table and prices accordingly. Second, a unified renewal calendar eliminates the ongoing risk of any single parish quietly lapsing onto an auto-renewed holdover rate while the rest of the portfolio sits on competitive fixed contracts. Once aligned, a diocese can review its entire electricity position — every parish, one report — instead of managing a dozen separate relationships with no shared visibility.

‍

This is the same underlying principle covered in our guide to renewing a church electricity contract in Texas, applied at portfolio scale rather than to a single congregation.

‍

Not Every Parish Is in a Deregulated Territory — and That Changes Diocesan Planning

‍

This is the point that generic church-electricity guidance almost never covers, because it rarely matters for a single congregation. It matters enormously for a diocese with parishes spread across multiple Texas metro areas.

‍

Not every part of Texas has retail electricity choice. San Antonio is served primarily by CPS Energy, a municipally owned utility — regulated, with no competitive supplier choice, though some outlying Bexar County addresses fall in deregulated Oncor territory. Austin works the same way: most of the city runs on Austin Energy, a regulated municipal utility, with deregulated Oncor pockets only in parts of the surrounding metro. El Paso is fully regulated by El Paso Electric, with no supplier choice available anywhere in that market. A diocese headquartered in or covering any of these areas will likely have some parishes that can run a competitive reverse auction and others that legally cannot, because they sit inside a regulated utility's exclusive service territory.

‍

This matters for how a diocese should plan its procurement project. The correct first step isn't assuming every parish is shoppable — it's mapping each parish's address against its actual TDU or regulated utility territory before building a procurement timeline. Parishes in Oncor, CenterPoint, or AEP Texas territory go into the competitive auction. Parishes in CPS Energy, Austin Energy, or El Paso Electric territory stay on their regulated utility's rate, and the diocese should not be quoted or promised savings on those specific accounts. A broker who doesn't make this distinction upfront is setting a diocese up for a confusing, inaccurate savings projection.

‍

Rectories, Schools, Parish Halls, and Cemeteries: Mapping the Full Footprint

‍

A "parish," from an electricity meter's perspective, is rarely just the church building. Most parishes maintain a rectory — the priest's residence — a parish hall or activity center used for meetings, receptions, and religious education, and, in many cases, an attached or nearby parish school. Larger or older parishes frequently also maintain cemetery offices, maintenance buildings, or convents. Each of these structures may carry its own separate electricity meter and account, under a separate contract, potentially with a different provider or a different expiration date than the church itself.

‍

Before running any diocesan-level procurement, the practical first step is a complete meter inventory: every account tied to every parish, matched against the physical structure it serves. This is exactly the kind of documentation work a broker should be doing on the diocese's behalf, not something diocesan staff should be expected to compile themselves account by account. Once every meter is mapped, the diocese can make an informed decision about which accounts to combine into a single contract per parish and which — a large parish school running a materially different load profile than the church itself, for instance — might be better served by its own tailored rate structure. For parishes operating a school on the same campus, our guide to Texas school and university electricity procurement covers how educational usage patterns differ from a congregation's. For the specific case of a parish school sharing a campus, and possibly a meter, with the church itself, see our guide to electricity for Christian and private schools on a church campus.

The Sales Tax Exemption Applies the Same Way — Filed Per Account

‍

Under Texas Tax Code §151.310, qualifying religious organizations are exempt from state and local sales tax on electricity purchased for their regular place of worship — typically 6.25% at the state level, with local jurisdictions adding up to another 2%, for a combined exemption of up to 8.25% depending on the parish's city. This exemption applies to Catholic parishes on exactly the same statutory basis it applies to any other qualifying religious organization, covered in more depth in our guide to the Texas church electricity sales tax exemption.

‍

The detail that matters at diocesan scale: the exemption is filed per account, with Texas Comptroller Form 01-339 submitted to each parish's electricity provider individually. It does not apply automatically across a diocese's full portfolio just because one parish has filed it, and it does not transfer automatically when a parish switches providers as part of a diocesan-wide procurement — a new certificate has to go to the new provider for every account. In a portfolio the size of a diocese, this is exactly the kind of administrative step that gets missed unless someone is tracking it centrally. When we run a diocesan procurement, confirming exemption status — and filing it where it's missing — is built into the same process as the rate transition for every account, not treated as a separate task each parish has to remember on its own.

‍

Financial Governance and Documentation

‍

Diocesan financial decisions typically involve a layer of review that an individual parish contract renewal usually doesn't — a diocesan finance council, a vicar for administration, or a central business office that expects documented, competitive bidding before a portfolio-level contract is approved. A reverse auction structure fits naturally into that kind of review process: instead of a single negotiated quote, diocesan financial staff receive a clear, itemized comparison of every competing bid across the full parish portfolio, in a format built for board or council-level review rather than a single verbal recommendation.

‍

This is the same documentation standard we already provide for Texas school districts and municipal government portfolios, both of which operate under comparable procurement oversight requirements — see our education electricity procurement guide for how that documentation is structured in practice.

‍

What a Diocesan Procurement Engagement Looks Like

‍

The process starts with collecting the most recent electricity bill for every parish account across the diocese — this is how we identify each account's TDU territory, current provider, current rate, and contract expiration date in one pass, without diocesan staff needing to track any of it down separately. From there, we build a single portfolio load profile, separate the accounts that sit in deregulated territory from those that don't, and run a competitive reverse auction with 25+ licensed Texas providers bidding against each other for the shoppable portion of the portfolio.

‍

The diocese reviews one consolidated comparison covering every parish, rather than a dozen separate conversations. Contracts that are ready to transition move immediately; parishes with contracts not yet near expiration are scheduled into a unified renewal calendar so the whole portfolio eventually lands on aligned terms, rather than staying permanently staggered. Tax exemption certificates are filed alongside each transition. There is no cost to the diocese for any part of this process — provider commission funds the broker relationship, the same structure that applies to any commercial account.

‍

Frequently Asked Questions

‍

Does every parish in our diocese need to switch providers at the same time?

No. Parishes with contracts still under term can be scheduled into a coordinated renewal calendar rather than switched immediately, avoiding early termination fees while still moving the whole portfolio toward aligned terms over time.

‍

What if some of our parishes are in San Antonio, Austin, or El Paso?

Parishes served by CPS Energy, Austin Energy, or El Paso Electric are in regulated territory and cannot run a competitive reverse auction for electricity supply — those accounts stay on the regulated utility's rate. We identify which parishes fall into this category before quoting the portfolio, so the diocese isn't given savings projections that don't apply to every location.

‍

Do rectories and parish schools need separate contracts from the church itself?

Not necessarily — it depends on how each structure is metered. Some parishes run the church, hall, and rectory on a single account; others have each building separately metered. We map every meter tied to a parish before recommending whether to combine or separate accounts.

‍

Is there a cost to the diocese for running a portfolio-wide procurement?

No. Our compensation comes from a standard commission paid by the winning provider on each account — the same structure that applies to any commercial electricity account, single-location or portfolio-wide.
