The borders where outages information is available are mapped as time series. These are a great substitute to the net transfer capacities on ENTSO-E, because the REMIT messages are more up to date.
We have mapped 1300+ power plants and keep adding more on a regular basis. Whenever we receive an outage message for a power plant, we generate a new time series right away with up-to-date capacities.
If you wish to know what the current aggregated available capacity is for coal-fired plants in Poland, we have already quantified it for you. And we've also done the same for other fuel types in all other price areas.
Not only do we cover the reported available capacity for individual power plants, we also calculate the actual production for a almost all of them. It's quantified and prepared for you to view online or download.
