Transition timing from nrel.gov to nlr.gov

[brtietz]

We recently heard from NLR IT that nrel.gov is likely to go away on May 29th. This means we expect redirects to stop working on that date. API calls to NSRDB, PVWatts and similar to the new nlr.gov address to maintain functionality. Updating links to reports in citations could also save users time.

Note that developer.nlr.gov is not ready yet, I'm giving an "advanced" heads up for roadmap/release planning. I'll post again when more of these services are ready.

Official schedule from the developer.nlr.gov team is available:

• March 2, 2026: The new developer.nlr.gov domain is available now to use and begin switching API calls to the new URLs. You can find API documentation at https://developer.nlr.gov).
• May 1, 2026: Periodic brownouts (scheduled outages for short durations) will begin where traffic to the old developer.nrel.gov domain will return errors with instructions about using the new domain. Traffic already switched to the new developer.nlr.gov domain will not be affected.
• May 29, 2026: The developer.nrel.gov domain will expire and stop working completely. DNS for the nrel.gov domain and all subdomains will cease to resolve and will not redirect.

Please reach out if you have any issues with the new urls. (We've seen a few NSRDB hiccups from SAM and REopt this afternoon, those should be resolved in a few hours at most)
