  • “The NAESB copyright most definitely extends to Third Parties/vendors that would need access to the standard to produce Green Button / ESPI streams or files. We have segments in each of our quadrants for service companies and many member service companies that provide support [to] the utilities, transmission providers, pipelines, local distribution companies, etc. “At the very least, if a company/ individual is offering a ‘product/service’ that conforms to the standard, then we expect the company/individual to have valid legal access to the standard.” — Jonathan Booe, North American Energy Standards Board
