This data hub, COVID-EMDA+ (Coronavirus Disease - Electricity Market Data Aggregation+), is specifically designed to track the potential impacts of COVID-19 on the existing U.S. electricity markets. Many different data sources are merged and harmonized here in order to enable further interdisciplinary researches.
Based on the data hub, we have developed a supporting toolbox to realize a series of advanced analysis. Both Python and Matlab versions are available, and read more at this link.
- Overall, this data hub contains the
coronavirus case & deaths,weather,generation mix,loadandprice datafor all the existing U.S. electricity marketplaces (CAISO, MISO, ISO-NE, NYISO, PJM, SPP , ERCOT) and some typical cities in these markets (Los Angeles, Boston, New York City, Philadelphia, Chicago, Kansas City, Houston). We also integrate other additional resources, including themobile device location,night-time lighting images,load forecasting,congestion price,forced outageandrenewable curtailment data. Historical data dating back to 2017 are included as time-series benchmarks. - This data hub is updated every day after careful quality control. All data are carefully verified and coordinated to match the geological scale. All data are recorded and tidied in a consistent, compact and ready-to-use data format that makes it easy for cross-market analysis.
- Some useful parsers as well as supplementary resources are provided for other user-defined extensions.
- A supporting toolbox written in Python and Matlab is realized to make the data-driven analysis as easy as possible.
This data hub mainly contains five components: source data, released data, supplementary resources, parser codes, and quick-start tutorials. We navigate this data hub as follows.
All the data source files are archived in folder date_source/, the cleaned and processed data are stored in folder data_release/. The support team will conduct daily updates to capture the latest data. All these files are properly collected by location. The file naming convetion for this data hub is: MARKET_AREA_CATEGORY.csv, e.g. nyiso_nyc_load.csv is a dataset of load profile in New York City from 2017 to present.
Readers can turn to folder startup/ for quick start, supplementary/ for addtional data and codes in our research work, and parser/ for the basic tools to handle the source files.

Electricity Market Data:
Description: This part includes the generation mix, metered load profiles and day-ahead locational marginal prices data. We also include the day-ahead load forecasting, congestion price, forced outage and renewable curtailment data as the supplementary source.
Link: CAISO, MISO, ISO-NE, NYISO, PJM, SPP, ERCOT, EIA, EnergyOnline. -
Public Health Data:
Description: This part includes the COVID-19 confirmed cases, deaths data, infection rate and fatal rate. We aggregate and fine-tune the data to market and city levels.
Link: John Hopkins CSSE. -
Weather Data:
Description: This part includes temperature, relative humidity, wind speed and dew point data. Typical weather stations are selected according to their geological locations and data quality.
Link: Iowa State Univ IEM, NOAA. -
Mobile Device Location Data:
Description: This part includes social distancing data and patterns of visits to Point of Interests (POIs). These data are derived by aggregating and processing the real-time GPS location of cellphone users by Census Block Group.
