What is Grid Status?#
gridstatus is a standardized Python API to electricity supply, demand, and pricing data for the major Independent System Operators (ISOs) in the United States.
Currently gridstatus supports CAISO, SPP, ISONE, MISO, Ercot, NYISO, and PJM.
We’d love to answer any usage or data access questions! Please let us know by posting a GitHub issue.
5 Minute Overview#
First, we can see all of the ISOs that are supported
import gridstatus
gridstatus.list_isos()
| Name | Id | Class | |
|---|---|---|---|
| 0 | Midcontinent ISO | miso | MISO |
| 1 | California ISO | caiso | CAISO |
| 2 | PJM | pjm | PJM |
| 3 | Electric Reliability Council of Texas | ercot | Ercot |
| 4 | Southwest Power Pool | spp | SPP |
| 5 | New York ISO | nyiso | NYISO |
| 6 | ISO New England | isone | ISONE |
| 7 | Independent Electricity System Operator | ieso | IESO |
Next, we can select an ISO we want to use
caiso = gridstatus.CAISO()
Fuel Mix#
All ISOs have the same API to methods like get_fuel_mix, get_load, and get_status, etc. Here is how we can get the fuel mix
caiso.get_fuel_mix("today")
| Time | Interval Start | Interval End | Solar | Wind | Geothermal | Biomass | Biogas | Small Hydro | Coal | Nuclear | Natural Gas | Large Hydro | Batteries | Imports | Other | |

Frequently, we want to get data across multiple days. We can do that by providing a start and end parameter to any iso.get_* method
caiso_load = caiso.get_load(start="Jan 1, 2021", end="Feb 1, 2021")
caiso_load
