Electric_plants {deaR}

Data: Färe, Grosskopf and Kokkelenberg (1989).

Description

Data of 19 coal-fired steam-electric generating plants operating in Illinois in 1978. Each plant uses 3 inputs to produce 1 output.

Usage

data("Electric_plants")

Format

Data frame with 18 rows and 5 columns. Definition of inputs (X) and outputs (Y):

x1 = Labor

Labor average annual employment

x2 = Fuel

Fuel 10^{10} Btu

x3 = Capital

Capital MW (fixed input)

y1 = Output

Output 10^6 Kwh
