Procurement and pricing of reserves
(.pdf) Gate closure for different reserves is presented in Figure 1. The reserves FCR-N, FCR-D upward and FCR-D downward are procured during two complementary auctions one day (D-1) ahead. The majority of the capacity for FCR is procured in the first auction, the rest is procured in the second auction. The reserve aFRR is procured D-1. Energy bids for mFRR are cleared during the operating hour if needed. Bids for mFRR shall be submitted no later than 45 minutes before the operating hour. The reserve FFR, which is not included in Figure 1, is procured on a yearly basis. FFR is cleared two times per week (Monday and Friday).

Your possible earnings depend on the capacity and/or energy you have available to bid as well as the price you choose for your bid.
You can get an indication of how much you can earn on each market by looking at historical prices for cleared volumes. Historical prices can also be used to get an indication on how to price your bids. Remember that the pricing of your bid should cover any eventual investment cost, operational cost as well as desired return on investment.
Capacity remuneration = Price (Pay as cleared or Pay as bid) * sold capacity (MW)
Energy remuneration = Price (upward or downward regulation) * activated energy (MWh)
Capacity market
A market where capacity is procured. Bids are cleared usually one day before the day of operation. The capacity remuneration is always received for accepted bids, independent of any energy activation. Some capacity markets also include energy remuneration for the actual energy activations.
Energy activation market
A market where energy is procured. Bids are cleared during the operating hour. Energy remuneration is received for the actual energy activations. No capacity remuneration is received.
