Public Service Enterprise Group (PSEG) is a diversified energy holding company headquartered in Newark, New Jersey. Its regulated utility subsidiary Public Service Electric and Gas (PSE&G) is New Jersey's largest electric and gas distribution utility, and PSEG Long Island operates the transmission and distribution system on behalf of the Long Island Power Authority. PSEG sits squarely in the utility-retailer tier of the United States energy value chain — it meters, bills, and serves end customers, and it sells generation into the PJM wholesale market rather than publishing that market's data itself. Its API posture is honestly closed. There is no developer portal: developer., developers., api., docs., and data.pseg.com do not resolve, and /developers, /api, and /docs on pseg.com return the site's soft-404 page. Green Button is present only as a file: PSEG Long Island's MySmartEnergy FAQ states customers can "download data information in CSV or Green Button (.XML) format," which is Download My Data behind a customer login, not Connect My Data. There is no documented programmatic third-party access to customer usage data — in the New Jersey BPU AMI docket PSE&G described manual secondary-user sharing, a Letter of Authorization with spreadsheets emailed back, and EDI for BPU-licensed suppliers. Grid data is equally closed: the PSE&G NJ and PSEG Long Island outage maps are vendor-hosted KUBRA StormCenter applications with no published data API. Open market data for this territory comes from PJM and the EIA, not from PSEG.
