The one-third factor relates to the thermodynamic efficiency of the boiler.\n(3) To express this in MWe, the standards conversion of 3413 Btu to 1 kw-hr is used: 113.3 × 10 6 Btu/hr × 1 kw-hr / 3413 Btu × 1 MWe / 1000 kw = 33.2 MWe","path":["Title 40—Protection of Environment","CHAPTER I—ENVIRONMENTAL PROTECTION AGENCY","SUBCHAPTER C—AIR PROGRAMS","PART 72—PERMITS REGULATION"],"source_url":"https://www.ecfr.gov/api/versioner/v1/full/2026-08-25/title-40.xml","current_through":"2026-08-25","vintage":"","retrieved_at":"2026-08-27T02:26:04Z","sha256":"fdbf3ccd4ae1a47a313ef4ec0b0974ecc98b4e091132476ecc39b92378e9e927","source_id":"us-cfr","stale":true,"prev":"us/40-cfr-appendix-c-to-part-72","next":"us/40-cfr-73.1"},"notice":"GroundRules: Original legal text.
