1. Why does IMPLAN break out the “Electric power generation, transmission, and distribution” Industry?
IMPLAN breaks out the “Electric power generation, transmission, and distribution” Industry into eight electrical power generation Industries and one electric power transmission and distribution Industry. This is due to a growing interest in more detail behind the generation and sale of electricity in ways that help businesses, analysts, and policy makers understand the change in both the technologies and economics that underpin the consumption of electricity.
2. How is the electricity generation and distribution data is handled in IMPLAN?
- First, generation by sector is gathered in Megawatt-hours (MWH) from the US Energy Information Administration
- These are in MWH, not dollar values
- http://www.eia.gov/electricity/data.cfm#generation
- Next, we obtain total revenue for all electricity from the US Energy Information Administration
- These are not broken out by Sector
- http://www.eia.gov/electricity/data.cfm#generation.
- With the value from #2 and the sum of total generation from #1, we calculate a revenue per MWH value, which we multiply against the generation by sector from #1 to get an estimate of revenue by sector.
- We then split that revenue by sector into generation vs. distribution using the share of price between generators and distributors - http://www.eia.gov/electricity/annual/html/epa_02_04.html.
- Finally, we split between private, federal, state, and local based on CEW data, which have enough detail for all generation types plus distribution.
