Yes, a proposed data center could affect local electricity costs, grid reliability, or water availability—but its size alone cannot tell you whether it will. To assess a specific project, find the utility and water-service records, determine which authority is reviewing it, and check the project’s demand, planned upgrades, cost agreements, water source, and permits.
Start by identifying who serves and reviews the project
Write down the project name, address, parcel number, and proposed development stages. Then identify the electric utility serving the site, the local water supplier, the local planning or zoning authority, and the state utility and environmental regulators. A grid operator may also have information about large-load requests or system planning.

Responsibilities are divided differently in different places. Michigan’s official Data Centers overview describes state oversight of matters such as electric service, water withdrawals, air emissions, wastewater, and wetlands, alongside local authority over land use and community impacts. Treat that as an example of how responsibilities can be split—not a map of your own state’s rules.
Look for the local planning, zoning, or development case file and note the reviewing body, hearing dates, filing deadlines, and instructions for public comments. If you cannot find the file online, ask the clerk or planning department which office has it and how to request records. Some utility agreements may be confidential or redacted, so ask what is withheld and whether a public summary or regulatory filing is available.

Could the project raise your electricity bill?
Large electricity demand does not by itself prove that household bills will rise, nor that they will be unaffected. The key questions are whether the utility can serve the project, what new supply and network work is needed, how costs are assigned, and what the applicable rate or contract requires.
Records and figures to look for
- Demand and timing: peak demand in megawatts and expected annual electricity use, both for the first operating phase and full build-out. Check whether figures assume all planned buildings and equipment will operate at once.
- Available capacity and upgrades: the utility’s assessment of existing capacity, any expected new generation, transmission lines, substations, or distribution work, and when each would be needed.
- Who pays: the proposed allocation of costs for generation and grid upgrades, including whether the customer pays if the project is delayed, uses less electricity than forecast, or is abandoned after work begins.
- Rate and service terms: the applicable tariff or large-customer electric service agreement. Check demand charges, minimum-payment terms, collateral, and any conditions for service. Ask whether terms are redacted and whether the regulator has a public filing or analysis.
- Reliability and planning: utility resource plans, rate cases, interconnection filings, reliability studies, and meeting records that discuss the project, its timing, or alternatives.
Minnesota’s Public Utilities Commission describes its role as overseeing safe, reliable electric service at just and reasonable rates and explains electric service agreements for significant large-customer loads. That is useful context for the kinds of records to seek; the applicable regulator and rules depend on where the project is proposed.

Pennsylvania provides a state-specific example, not a nationwide rule: its 2026 GRID requirements describe commitments for developers to cover incremental electricity supply and needed infrastructure costs. Check your own state’s law and the project’s actual contract rather than assuming those protections apply elsewhere.
Will it use drinking water, and how much?
Ask for the water source and the project’s expected withdrawals and consumption—not just a single annual estimate. A project connected to a municipal system raises different questions from one using groundwater, surface water, reclaimed water, or another source. Withdrawal and consumption are not interchangeable: some water may be returned to the system, while some may be lost through operations such as evaporation.

Records and figures to look for
- Source and service: whether the project will use municipal drinking water, groundwater, surface water, reclaimed water, or another source; whether a water-service commitment or allocation exists; and what capacity the supplier says is available.
- Use over time: projected daily and annual withdrawals and consumption for initial operation and full build-out, with peak-season estimates and stated assumptions.
- Cooling and stress conditions: the cooling design and expected water needs during ordinary operations, heat waves, drought, and water restrictions. Ask whether the operating plan changes when supplies are constrained.
- Permits and wastewater: relevant withdrawal, well, discharge, wastewater, stormwater, and construction permits, plus the technical material supporting them.
- Competing needs and safeguards: what the water provider or regulator says about existing customers, planned growth, emergency reserves, and ecological needs, and what enforceable limits or drought provisions apply.
Massachusetts Executive Order No. 658 calls for water-quality and water-quantity protections for covered projects over 25 MW and directs development of reporting guidance. The order scheduled municipal guidance for December 31, 2026; as of October 4, 2026, that date had not yet arrived. These are Massachusetts-specific provisions, not a general threshold for other jurisdictions.
ERCOT’s 2026 State and Community Impact RFI asks covered developers about water sources, consumption, and cooling technology. ERCOT listed October 12, 2026, as the submission deadline and said it intended to publish its report by December 10, 2026. Those dates and questions concern a Texas process, not a deadline or requirement for projects elsewhere.

How to judge whether a promise is meaningful
Distinguish a developer’s projection from a utility or regulator’s finding, and both from a binding condition. A presentation may describe a plan; an executed agreement, permit, tariff, or approval condition is where obligations and limits are more likely to be specified. Read the actual document and identify who is responsible, what triggers the obligation, and what happens if assumptions change.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
- Compare project estimates with the utility’s or water supplier’s capacity assessment, not only with broad industry averages.
- Check whether the figures cover the same build-out stage and time period. A first-phase estimate is not a full-build-out estimate.
- Look for contingencies: delayed construction, lower-than-forecast demand, equipment changes, drought, or retirement of new infrastructure.
- Separate projected public revenue or jobs from evidence about household utility bills, water-system capacity, or enforceable protections.
A site-specific municipal page can be useful when it publishes actual project details. For example, the City of Batavia’s project update describes material for its proposal including closed-loop cooling, municipal water-use limits, and projected utility and general-fund revenue. Check the city’s current project page and filings for current status and terms; a municipal update is not a substitute for the underlying agreements or permits.

Compare proposals on the same basis
If you are comparing two projects or a project with a utility plan, use the same time horizon and build-out assumptions for both. Mark information as missing rather than treating it as zero or assuming the proposals are equivalent.
| Electricity | Water |
|---|---|
| Peak demand and annual consumption at each build-out stage | Water source, peak withdrawal, and annual consumption at each stage |
| Existing capacity versus new generation and network upgrades | Cooling design, seasonal demand, and drought behavior |
| Who pays for each upgrade and which tariff or contract applies | Water-system capacity and the provider’s supporting assessment |
| Reliability analysis, upgrade timing, and contingency plans | Permits, wastewater and stormwater plans, and enforceable limits |
| Responsibility if construction is delayed, load is lower than forecast, or equipment is retired | Response if supply is constrained or operating conditions change |
The comparison is only as useful as the underlying records. Different assumptions, time periods, or project phases can make two headline estimates look comparable when they are not.
What to ask at a hearing or in a records request
Keep questions specific enough that the utility, developer, or reviewing agency can answer them with a document or a measurable commitment. Submit comments by the stated deadline and ask the reviewing body to include responses in the public record.
