🔔 EIA-860M Monthly Generator Inventory

One structured generator_record per generating unit in EIA's monthly Form EIA-860M inventory — entity, plant, state, balancing authority, technology, energy source, prime mover, nameplate and net summer/winter capacity, operating/retirement dates, and status — carried verbatim from the official monthly workbook.

Differentiation: the current, filterable, billing-honest slice of EIA-860M as structured records — not a re-hosted spreadsheet. Pick an inventory (Operating / Planned / Retired / Canceled), optionally add Puerto Rico, filter by state / balancing authority / energy source / technology / entity, and pay per delivered generator. A per-release schema canary refuses to bill if EIA changes the header.

Output is one generator_record row per result; billing is pay-per-event, the value event being one generator record (a $0.02 start fee per run, then $0.02 per generator record). Source: www.eia.gov.

No login, no API key and no CAPTCHA solving are involved: the source is read logged-out with an identified contact User-Agent.

📊 Sample Output

Fields & exclusions

status / fuel / capacity fields are carried verbatim. The "Google Map" and "Bing Map" columns (and their third-party logos) are excluded and never emitted. A composite record_key (plant × generator × unit × sheet) is the source-native id.

⚙️ Sample inputs

1. Quick start — the Store example (this is what the sample above came from)

{
  "statusCategory": "Operating",
  "plantState": "AK",
  "maxRecords": 50
}

The sample run charged exactly: 2 × $0.02 apify-actor-start + 50 × $0.02 generator_record = $1.04 on the Free tier — every delivered row was billed.

2. A smaller, narrowed run

{
  "statusCategory": "Operating",
  "plantState": "AK",
  "maxRecords": 5
}

Caps the run at 5 rows — about $0.12 on the Free tier ($0.02 start + 5 × $0.02). statusCategory narrows what the source is asked for.

3. A full-size run

{
  "statusCategory": "Operating",
  "plantState": "AK",
  "maxRecords": 2500
}

Up to 2500 rows (the schema default for maxRecords) — about $50.02 on the Free tier ($0.02 start + 2500 × $0.02) if the source has that many.

4. A filtered run

{
  "statusCategory": "Operating",
  "plantState": "AK",
  "maxRecords": 50,
  "fieldMatch": {
    "entity_name": "Sand Point Generating, LLC"
  }
}

Keeps only rows whose entity_name contains Sand Point Generating, LLC (a value from the sample run above), matched case-insensitively after the source is read and before the maxRecords cap, so the cap counts matches and only delivered matches are billed. searchText does the same across every column. Zero matches end the run as EMPTY_SELECTION with no row charged — if the source has moved on since that sample run, pick a value you see in your own first run. The source is still read in full — this narrows what you receive and pay for, not what the source serves.

🔧 How it works

Source. The actor reads www.eia.gov — endpoints: https://www.eia.gov, https://www.eia.gov/electricity/data/eia860m/. Public pages and feeds only; nothing behind a login.

Transport. Plain HTTPS from the Apify platform, no proxy. robots.txt is read first and a disallowed path is never fetched. Every request carries an identified contact User-Agent. Pacing: CRAWL_DELAY=0.0.

Terminal states. A run ends NORMAL, CAPPED (your cap was reached), PARTIAL (something was withheld and the message says what), GENUINE_EMPTY (the source was read and truly had nothing in scope) or BLOCKED (the source refused or changed shape — the run FAILS loud and bills nothing). A zero-row run is never reported as a silent success.

Charging. Each generator record is charged at the moment it is pushed (generator_record); a row that fails to charge is not delivered, so the dataset count always equals the charged count.

🔧 How it works

Source

The official EIA-860M monthly workbook only — the current, non-archive file resolved from https://www.eia.gov/electricity/data/eia860m/ (xls/<month>_generator<year>.xlsx). eia.gov robots disallows the /archive/ path, which is never fetched; only the current published file is read.

Preliminary data

EIA marks monthly EIA-860M data as PRELIMINARY; this actor states that and never overrides it — figures are the preliminary values EIA published for the release month.

Licence & acknowledgement

Form EIA-860M is a U.S. Government work (public domain). Acknowledgement: data from the U.S. Energy Information Administration. Third-party materials and logos are excluded.

Billing

Pay-per-event. generator_record is charged once per delivered record ($0.02), GOLD-floored −10 / −20 / −33% volume ladder. apify-actor-start ($0.02) is platform-reserved, never charged in code. A filter that matches nothing is a clean success — nothing billed. A drifted header fails loud — nothing billed.

What is not done. No login, no cookie or CAPTCHA bypass, no private or personal-account data, no browser automation.

💰 Pricing example

Event	Free	Bronze	Silver	Gold
Actor Start (`apify-actor-start`)	$0.02	$0.02	$0.02	$0.02
Generator Record (`generator_record`)	$0.02	$0.018	$0.016	$0.0134

Worked at the live Free-tier price:

8 generator records: $0.02 start + 8 × $0.02 = $0.18
25 generator records: $0.02 start + 25 × $0.02 = $0.52
2500 generator records: $0.02 start + 2500 × $0.02 = $50.02

A run that delivers zero rows charges the $0.02 start fee only. A BLOCKED run (source refused) fails loud and charges no value event. The start fee is charged once per GB of run memory; the default run memory is 4096 MB.

Yield on the sample run: NORMAL: 50 unique rows (0 duplicates collapsed) from july_generator2026. billable=50. maxRecords is a hard ceiling on what is delivered and billed, never a target.

⚖️ Legal & ToS

This actor reads public, logged-out pages and feeds published by www.eia.gov. It collects only what the source publishes to any visitor, keeps to the source's robots rules (checked on every run), identifies itself with a contact User-Agent, and does not access accounts, private data or anything behind authentication. Use the output in line with the source's terms and your local law; the intended use is B2B research and monitoring.

❓ FAQ

Q: Do I need an API key or a login?
A: No. The source (www.eia.gov) is read logged-out; the input schema has no key field and the actor carries no secrets.

Q: Why did my run return 0 rows?
A: Read the run's status message. GENUINE_EMPTY means the source was read and had nothing in scope for your input; BLOCKED means the source refused and the run failed without billing a value event — retry later or narrow the input. A zero-row run bills the start fee only.

Q: How many rows can one run return?
A: Up to maxRecords (default 2500). Raise the cap for a bigger run; you pay per delivered row.

Q: How fresh is the data?
A: Every run reads the source live at run time; nothing is cached between runs. Put it on a schedule for a continuous feed.

Q: What formats can I export?
A: The dataset downloads as JSON, CSV, Excel, XML or RSS from the run's Dataset tab or the Apify API, and any run can push to a webhook or integration.

Q: How is this different from the other NexGen Watch actors actors?
A: Same output shape and billing model; this one covers www.eia.gov. The siblings under Related Actors cover the other sources or slices — run several on one schedule for a combined feed.

Q: Are there rate limits?
A: The actor paces itself against the source (CRAWL_DELAY=0.0) and honours its robots rules; there is no per-buyer limit beyond your Apify plan's concurrency.

🆘 Troubleshooting

Run FAILED with BLOCKED → the source refused the request or changed its page shape → nothing was billed beyond the start fee; retry after a while, and if it persists open an Issue with the run id.
Status says CAPPED → your cap (maxRecords) was reached → raise it for a bigger run.
Input validation error on start → a field is outside the schema's allowed values → start from the Quick start block and change one field at a time.
Run TIMED-OUT → a very wide request on a slow day → raise the run timeout in Run options or narrow the input; what was delivered before the timeout is still in the dataset.
