Overview

Distributed sheets of the discontinued distributed_generation file, succeeded by net_metering and non_net_metering_distributed. event_time is 1 January of the report year. release is final or early_release: EIA posts an early release of a year in August and replaces it with the final file in the autumn, and the mirror keeps the newest row per key. A key cell EIA leaves blank is '' or 0, and duplicate_index numbers rows that still share a key, in workbook order.

Query contract

Preserve one canonical row per (event_time, utility_number, state, duplicate_index) before aggregating.

Analysis rules

Group only after preserving the declared grain: event_time, utility_number, state, duplicate_index.

Dataset	Description
Balancing Authority Generation by FuelEIA · hourly	EIA-930 hourly net generation by energy source for every reporting balancing authority, one wide row per (ba, hour). 5.2M rows, 83 BAs, 2019-01 to now. Each EIA source code is its own additive column: coal, gas, oil, nuclear, hydro, pumped storage, wind, wind with storage, solar, solar with storage, battery, other and unknown storage, geothermal, other and unknown.
Dispersed GenerationEIA · annual (report year)	EIA-861 dispersed generation capacity by technology and utility, 2012 to 2015. Dispersed sheets of the discontinued distributed_generation file. event_time is 1 January of the report year. release is final or early_release: EIA posts an early release of a year in August and replaces it with the final file in the autumn, and the mirror keeps the newest row per key. A key cell EIA leaves blank is '' or 0, and duplicate_index numbers rows that still share a key, in workbook order.
Net MeteringEIA · annual (report year)	EIA-861 net metering: net-metered capacity, installations and energy sold back by technology, utility and customer class. Net_Metering, the utility-level sheets. Columns follow EIA's own labels across its renames: customers counts run to 2020 and installations from 2021, storage paired with PV is photovoltaic_storage_* to 2022 and battery_* from 2023, and 2012 counted meters. Capacity in MW, energy in MWh. customer_class is residential, commercial, industrial, transportation (direct_connected in the distributed generation tables) or EIA's own total, so summing classes without excluding total counts everything twice. event_time is 1 January of the report year. release is final or early_release: EIA posts an early release of a year in August and replaces it with the final file in the autumn, and the mirror keeps the newest row per key. A key cell EIA leaves blank is '' or 0, and duplicate_index numbers rows that still share a key, in workbook order.
Net Metering by StateEIA · annual (report year)	EIA-861 net metering state totals, by technology and customer class, 2023 on. The State Level sheet of Net_Metering, as EIA totals it. customer_class is residential, commercial, industrial, transportation (direct_connected in the distributed generation tables) or EIA's own total, so summing classes without excluding total counts everything twice. event_time is 1 January of the report year. release is final or early_release: EIA posts an early release of a year in August and replaces it with the final file in the autumn, and the mirror keeps the newest row per key. A key cell EIA leaves blank is '' or 0, and duplicate_index numbers rows that still share a key, in workbook order.
