etariff.ferc.gov is a real government website run by the Federal Energy Regulatory Commission (FERC), not a scam. It's been online for over 14 years and is used to file and search electric tariff documents. The site has strong security — valid encryption, HTTPS enforced, and no malware flags. So is etariff.ferc.gov safe for browsing public tariff data? Yes, it's fine for that.
Where you might want to be careful is if you're submitting filings or creating an account. The site has no contact page, no about page, and no privacy policy visible. For a federal system that handles regulated documents, that's a real gap. Most government portals at least publish a help desk number or an agency contact. Here, you're on your own if something breaks.
There's no history of security incidents or blacklisting, and the domain is clearly tied to ferc.gov. The robots.txt file blocks all search engine crawlers, which is unusual for a public database but could be intentional to keep the tariff data behind the tool's interface. If you're just looking up rates or filings, you're fine. If you need to file, make sure you have a direct contact for support first.
