Find out who may supply the power, what new equipment is planned, who may pay, and how you can take part.
START HERE / ABOUT 2 MINUTES
What do you want to find out about electricity?
You don’t need to know how the power grid works. Choose your question, then follow the first steps. It’s okay if you don’t know the answers yet.
Who will supply power to the data center?
- Find the site. Start with an address, road name or county. Ask the local clerk if you need help.
- Check the electric provider. A provider listing is a lead. Confirm service for the actual property.
- Find any public filings. Look for the utility name and related plans or cases.
Is a new power line or substation planned near me?
- Find the project record. Check official plans, meeting papers and utility filings.
- Check its status. Proposed, approved, surveyed and built do not mean the same thing.
- Ask for maps. Request any public route maps and plans that the government holds.
Check what a map really proves or open a ready-to-copy records request.
A nearby power line is not proof it will serve a specific data center or cross your property.
Could a data center change who pays for electricity?
- Find the utility. Rate rules and oversight depend on the provider.
- Find the case or rate plan. Look for public filings about large customers and new equipment.
- Ask who pays. Check what the records say about costs for large customers and other ratepayers.
Read the guide to utility costs and rates.
A proposal or rate case does not, by itself, prove that bills will go up.
How can I speak up or ask for records?
- For utility cases: Find the Missouri Public Service Commission (PSC) case and check its participation rules.
- For air or water: Find the Missouri Department of Natural Resources (DNR) permit notice and any comment deadline.
- For missing records: Ask the correct public office for documents and save a copy of the request.
PSC comments and hearings · DNR permits and comments · Records request templates.
Public comments, participation as a party in a case, and legal appeals have different rules. If land rights or deadlines are at stake, speak with a Missouri attorney promptly.
Keep your evidence: Save the document title, date and link. This is a research guide, not a live power map or a finding about any specific site.
Data centers depend on more than a single parcel. Their potential infrastructure footprint can include substations, transmission connections, power plants, batteries, roads and environmental permits. This guide helps Missouri residents investigate those connections using public records without turning an unverified map into a claim of fact.
01 / Start with the parcel
Start with a place, not an assumption
Choose a proposed site, nearby property or named utility project. Collect the county, parcel number, legal description, municipal boundaries, project names and aliases, and a dated source before drawing any lines.
- Find the county assessor or GIS parcel page and check the parcel ID and ownership information shown there. Confirm property transfers using the county recorder when necessary.
- Determine whether the site is inside a municipality or in unincorporated county jurisdiction. A mailing address is not evidence of incorporated limits.
- Look for the actual site-plan file, public meeting packet, survey or recorded easement. Record the document title and date.
- Open the Missouri Legal Guide for the local land-use and appeal side of the project. Mapping a parcel does not determine who may approve a transmission line.
02 / Identify the utility chain
Who provides, transmits and regulates the electricity?
Utility service is not the same as ownership of every line or station in the area. One organization may supply retail electricity while another owns or operates a transmission asset. A developer may separately request a dedicated service connection.
| Question | Best first place to look | What it does not prove |
|---|---|---|
| Who supplies a local address? | PSC Utility Locator; then verify with the utility and service-territory documentation | The PSC listing is a locality-level lead; a city or county can contain more than one provider. |
| Which Missouri PSC case concerns it? | PSC EFIS and case search | The existence of a docket does not mean its application was granted. |
| What regional grid facilities are planned? | MISO Transmission Expansion Plan | Regional planning references are not property-level permits or final surveys. |
| Who may represent utility consumers? | Missouri Office of Public Counsel and the PSC case docket | A hearing or investigation does not guarantee a particular outcome. |
Classify the provider: investor-owned utility, electric cooperative, municipal utility, or another documented arrangement. Missouri PSC oversight differs by utility type; do not assume the same approval and rate processes apply to each. The PSC describes its primary rate/service jurisdiction as covering investor-owned utilities, with different and more limited oversight for other categories.
PSC permission: §393.170 addresses certificates for certain utility construction and franchises. Whether a specific project requires new PSC approval depends on the utility, type of work, and existing authority. Ask for the particular case number and order rather than stating that every upgrade requires a new certificate.
PSC participation: comments, hearings and intervention
Find the proceeding first. Search PSC EFIS for the utility and case number. Read the latest orders to confirm whether comments, a public hearing or intervention are available and what deadlines apply.
- If you want to comment: use the PSC public-comment page (online, email, phone or mail). Provide the case number and concrete questions or evidence. Public comment alone does not make you a party.
- If a public hearing is listed: follow its notice for time, location, virtual access and any registration instructions. Not every case has a hearing.
- If you want formal party status: consider a motion to intervene under 20 CSR 4240-2.075, subject to the specific case’s orders and intervention deadline. The Commission decides whether to grant it; organizations should verify representation requirements and consult a Missouri attorney when appropriate.
- If concerned about utility customers: contact the Missouri Office of Public Counsel, which represents public interests in PSC matters. It is separate from PSC Staff and is not your individual attorney.
Deadline and privacy note: public comments and records requests do not pause intervention or appeal deadlines. Docket submissions can become public; avoid including sensitive personal details.
03 / Separate assets and proposals
Know what you are actually mapping
| Item on a map | What to look for | What to avoid assuming |
|---|---|---|
| Existing transmission line | Operator, voltage if documented, dated utility map, recorded right-of-way | That its precise centerline matches a generalized public map. |
| Proposed line or tap | Applicant, approximate study route, alternatives, filing or hearing notice | That a proposed route is fixed or crosses a named parcel. |
| Substation or switching yard | Facility name, owner/operator, site plan, connection purpose | That all nearby projects use it just because they are close. |
| Generation | Power plant or solar/wind project, capacity, generation interconnection status | That generating capacity represents reserved data-center load. |
| Battery energy storage (BESS) | Battery site, operator, MW and MWh separately, interconnection and local approvals | That a battery is equivalent to generation or a guaranteed power source. |
| Data center | Land-use approval, developer/entity, publicly documented estimated demand | That a marketing projection proves actual electrical consumption. |
Keep MW (power) separate from MWh (energy). Record whether an amount is proposed, contracted, permitted, built or operating. Do not convert a project’s projected peak load into a measured consumption figure.
04 / Source hierarchy
Distinguish an official line from a possible line
For each claim, record the precise claim, what source supports it, the source date, and what still has not been established. A map image without a document title or publication date should be marked as a lead, not a confirmed route.
| Label to publish | Examples of acceptable support | Limits |
|---|---|---|
| Recorded / surveyed | Publicly recorded easement, survey, plat or exact legal description | Check recording date; a granted easement does not prove installation occurred. |
| Approved / ordered | Final signed permit, public commission order, adopted plan or ordinance | Approval may have conditions; it does not prove construction began. |
| Proposed: official filing | Dated application, filed route exhibit, utility plan or hearing packet | Geometry is an applicant’s proposal, not a confirmed final right-of-way. |
| Planned: regional or utility | MISO MTEP, utility IRP or publicly filed planning presentation | Scope and expected schedule may change; a planning entry isn’t parcel-level permission. |
| Queue / study | MISO generator interconnection queue, study status and request ID | A queue entry is an application/process stage; it is not proof of completion, financing or a specific data center. |
| Approximate / generalized | EIA U.S. Energy Atlas and other broad-area public maps | Do not use generalized map features as surveyed parcel crossings. |
| Unverified / disputed | News report, promotional slide, witness account or inconsistent records | Do not publish the route or causation as established. |
What MISO’s queue does and does not show
MISO’s public generator-interconnection resources let users research requests to connect new or changed generation to its transmission system, including certain storage projects. Record the project ID, fuel/technology type, requested MW, point of interconnection, status and update date only as shown in MISO’s current published data. A generator interconnection entry is not a complete list of data-center electricity demand, and it does not establish final location, commercial operation or a dedicated customer. Use MISO’s public queue and the MTEP planning materials as different sources.
What a PSC case proves
EFIS can contain applications, testimony, maps, correspondence, orders and conditions. Search by company, case number and project terms. Read the latest order and docket history. An application is not the same as an order; an order approving a project may be conditional and does not itself confirm that a surveyed path or construction timetable is final. For construction and franchises, see §393.170 where applicable.
What parcel maps and recorded easements prove
Parcel data show boundaries and tax-record attributes based on the county’s data; recorded instruments may show legal interests or right-of-way descriptions. If the map and recorded language disagree, keep both references until resolved. Do not claim that a route crosses private land from a small, low-resolution map alone. County recorder and survey records, not a broad energy atlas, are the right place to check a particular easement.
05 / Follow the paper trail
Search one project across the right systems
- Local government: applications, approved site plans, zoning decisions, public hearing packets, public works and road agreements, recorded instruments. Use county and municipal record systems, and the Sunshine Toolkit for targeted requests.
- PSC: use EFIS case search to find an electric, gas, water or related utility proceeding. Record the case number, filing type, decision and date.
- MISO: check generator interconnection, transmission planning and large-load additions separately. Generator queues do not list every data-center load; proposed large-load processes do not by themselves confirm a specific customer, reserved capacity or final route. Record each source date and status.
- FERC: use eLibrary when a federal docket or filed tariff, interconnection or other FERC-jurisdictional document is relevant. Search the docket, not just a company name; some material is nonpublic.
- Water and air: check Missouri DNR Clean Water permit search, applications in process, and DNR air public notices for distinct permit applications and open-comment opportunities.
- Regional map cross-check: EIA Energy Atlas can help locate generalized infrastructure; do not promote its approximate geometry to a surveyed route.
DNR: which environmental permit is pending, and can you comment?
Identify the permit program first. A project may involve separate air construction, air operating, water-discharge, wastewater or stormwater authorizations. Approval of one does not establish approval of the others.
- If an air application is pending: search DNR pending air permits. A filed or administratively complete application is not an issued permit and does not alone establish an open comment period.
- If DNR has published a draft notice: check air public notices and water public notices. Open the particular notice to find the draft, contact person, subject-matter rules, comment instructions and deadline. Hearings are not automatic.
- If the water record is unclear: use DNR’s pending-permits hub and the water permit search. Distinguish an individual site-specific permit from coverage under an existing general permit; public comment on the master general permit may differ from a facility’s coverage.
- If a permit has already been issued: get the permit, conditions and issue date. Ask DNR whether amendment, renewal, enforcement or a particular administrative review pathway remains available rather than assuming that an earlier comment window is open.
Always follow the deadline in the actual agency notice. A Sunshine request does not extend that deadline.
06 / Decision and accountability map
Who decides, who benefits, and who can answer?
A power-infrastructure map becomes more useful when it also identifies the institutions behind the equipment. Treat these as different questions: physical location, land approval, electric service, ownership, cost allocation and public oversight.
| Decision or effect | Where authority may sit | Records or question to pursue |
|---|---|---|
| Land use and site development | City or county planning body, elected governing body, board of adjustment, depending on local law | Adopted zoning, notices, signed decisions, appeal procedures. |
| Utility construction / routes | Utility, property owners, relevant public body and potentially PSC, depending on asset and authority | Filed PSC request/order, route alternatives, permits and recorded easements. |
| Grid planning | MISO and participating transmission owners; FERC-jurisdictional agreements when applicable | Transmission plan entries, tariffs, agreements and publicly available studies. |
| Costs and rates | Applicable utility tariff and regulator, contract and settlement arrangements | Tariff, large-load service agreement if public, rate-case testimony, allocation evidence. |
| Environmental review | DNR or applicable federal agency, sometimes local officials | Permit number, applications, comment deadline, agency decision. |
| Local incentives and tax effects | Governing body, industrial development authority, financing entities and taxing jurisdictions | Adopted agreements, projected and actual payments, votes, Chapter 100 documents. |
Make a separate column for documented benefit, documented cost, affected community and unresolved question. Do not assign liability or allege misconduct solely because an institution appears in more than one project record.
For rate concerns, the Missouri Office of Public Counsel provides information on PSC hearing participation. For local hearings and Sunshine requests, start with the Legal Guide and the records toolkit.
Who pays? Large-load tariffs, utility plans and rate cases
Begin with the utility type. If it is an investor-owned electric utility, consult the PSC’s large-load tariff guidance and EFIS case and tariff search. Cooperative and municipal utilities have different rate-setting and oversight arrangements.
- Large-load tariff: determine which proposed or approved rate schedule applies; check minimum service or demand commitments, security or collateral, exit obligations, line-extension charges and provisions allocating incremental costs. Record the effective date and any later revisions.
- Integrated Resource Plan (IRP): find the utility’s IRP and updates in EFIS. Examine load forecasts, planned generation, transmission, alternative scenarios and costs. A projection is not a guaranteed customer commitment or a project-specific permit.
- Rate case and cost allocation: examine utility, PSC Staff and Office of Public Counsel testimony and final orders. Ask whether infrastructure and financing costs are assigned to large customers, other rate classes, or shared, and what evidence supports that conclusion. Do not assume the tariff proves that households will pay all costs or none.
- Customer contracts: service agreements and customer names may be confidential. Record which documents are publicly accessible rather than inventing missing terms.
07 / Document your findings
Build a map ledger anyone can audit
Give each separate asset and decision a traceable record. Keep two labels: one for project status and another for location precision, so a proposed project is never mistaken for a surveyed, built line.
| Record field | What to enter |
|---|---|
| Record ID / aliases | Unique row ID; official project name; code names as disclosed, without merging unrelated names. |
| Asset and operator | Data center, station, line, generation, battery, pipeline, water/wastewater; developer versus actual asset owner. |
| Site and jurisdiction | County, city or unincorporated status, parcel ID or broad area when supported. |
| Electrical details | Voltage, MW, MWh, or capacity only as shown in a cited record; include units and purpose. |
| Project and route status | Existing / proposed / planning / application / approved / in construction / in service / unresolved. |
| Map precision | Recorded/surveyed / official proposed geometry / public approximate / location unknown. |
| Government and docket | The decision-maker, case number, official order or public-record reference. |
| Source and last checked | Direct URL or document reference, sheet/page, publication date and verification date. |
| Benefit / burden / next action | Documented beneficiary or payer, known community impact, open questions, hearing or records-request next step. |
Asset record ID: [ID] Official project / facility name: [name] Aliases / code names: [as written in sources] Asset type: [line / substation / data center / generation / battery / other] Owner / developer / operator (separate): [entities] Location / parcel / jurisdiction: [as supported] Voltage / MW / MWh (if verified): [figure + units] Project status: [proposed / approved / built / etc.] Location precision: [recorded / official proposed / approximate / unknown] Decision-maker / agency / docket: [name + case number] Supporting source: [exact link / title / page] Document date: [date] Last checked: [date] Known costs / benefits: [documented source or unresolved] Conflicts or gaps: [what remains uncertain] Next research step: [request / hearing / agency / record]
The button copies a blank record for use in a spreadsheet, shared research log or notes. It does not upload data to WCCRD.
08 / Ask for missing documents
Two adaptable records requests
Requests under Missouri’s Sunshine Law generally go to a public records custodian, not automatically to a private developer or all utility companies. Tailor the request to existing documents and an identifiable period. See the full Missouri Sunshine Law Toolkit for legal limits, fees, timing and denial follow-up.
Request local site plans, maps and approvals
To: Records custodian, [city / county / agency] Subject: Missouri Sunshine Law request: [project and location] Under Chapter 610, RSMo, I request electronic copies of existing public records held by your public body for [date range] concerning [project / parcel / route]: 1. Filed and approved site plans, utility-connection diagrams, corridor or alignment exhibits, and any publicly available route alternatives. 2. Written decisions, staff reports, public meeting notices, minutes and conditions relating to these plans. 3. Public easements, access agreements, road-crossing agreements, or correspondence transmitting filed utility maps, to the extent held by your office. 4. Public contracts or studies identifying responsibility for infrastructure costs, when responsive. Please provide records electronically if available, advise me of estimated fees before incurring charges exceeding [$ amount], and cite the specific legal basis for withholding any record or portion. Thank you, [name and reply email]
Request a specific utility docket or public study
To: Records custodian, [public agency] Subject: Missouri Sunshine Law request: [utility / facility / docket] I request copies of existing public records held by your office concerning [project, location, utility and date range]: 1. Filed project descriptions, alternative-route exhibits and publicly available maps. 2. Staff analyses, consultant reports, nonexempt correspondence and public findings. 3. Relevant signed orders, permits or authorizations and any conditions or later amendments. 4. Records identifying the owner/operator and project approval or construction status. Please identify any relevant public docket or direct public record system if these items are already online. If material is withheld, please provide nonexempt portions and the specific statutory reason for withholding. Please respond at [email]. Thank you, [name]
Do not use a records request to obtain restricted infrastructure-security information, private property access, or technical access credentials. A records request does not pause permitting or appeal deadlines.
09 / Responsible publication
Share evidence, not speculation
A defensible community map should help neighbors ask better questions, not create false certainty about someone’s property. Before sharing an image or spreadsheet, review these checks:
- Show status clearly. Label the map as a dated research snapshot. Separate existing, proposed and unresolved infrastructure.
- Use location precision labels. Generalized public maps are not a basis for alleging an exact parcel crossing or a taking.
- Explain project relationships. Show the document supporting each claimed relationship; proximity is not proof of causation or dedicated service.
- Keep private information private. Do not include home contact details, sensitive infrastructure access information or precise security-sensitive drawings in a public gallery.
- Correct transparently. Keep earlier sources in an internal record, note disagreements, and date revisions rather than silently replacing disputed claims.
- Separate approval from implementation. A permit, study, easement and constructed facility can have different dates and statuses.
