Abstract
This file describes the data and code for “The Cross-regional Impacts of Renewable Power Generation on the Electricity Market: An Empirical Study on Japan’s Electricity Spot Market” by Teng Ma, Yimeng Du, Tao Xu, and Wang Chen. The final cleaned dataset used in the paper is in .dta (STATA) format. Data sample period:2016/4/1 to 2020/3/31Data description:Spot Market Data:The spot price data of nine regions in Japan were obtained from the homepage of the JEPX. The dataset includes (i) transaction volume (100 GWh) and (ii) spot prices (Yen/kWh) in each area. Hourly price data were calculated as the hourly spot price by the mean of each two-time interval value in 1 hour, according to the 48 products traded in each 30-minute time interval within a day.Power Generation Data:The energy generation data in the electricity sector were acquired from nine traditional electric power companies (Hokkaido EPCO, Tohoku EPCO, Tokyo EPCO, Chubu EPCO, Hokuriku EPCO, Kansai EPCO, Chugoku EPCO, Shikoku EPCO, and Kyushu EPCO).The dataset contains various electricity power sources, such as nuclear, thermal, inflow-type hydroelectric, geothermal, biomass, solar, wind, pump-storage-type hydroelectric power, and regional power transmission by cross-regional interconnected lines. All the generation data were organized as hour-level data for each day.Utilization and Forecast Data:The utilization rate of the respective power generation facilities and the electricity demand forecast datasets were obtained from the Organization for Cross-regional Coordination of Transmission Operator, Japan.
