SourceOutputShare
Hydro 8 MW 100.0%
Total from these sources8 MW
Net interchange-10 MWnet imports

EIA publishes generation by source 10 or more hours after demand, so this hour can be earlier than the latest demand hour. Net interchange is positive when SPA exports.

The sources reported in this hour add up to 44% of demand, so the generation report for SPA looks incomplete and the shares above are shares of what was reported.
