The rules pursuant to paragraph 1 shall include a definition of the value of avoided activation of balancing energy from frequency restoration reserves or replacement reserves. 3. Each TSO shall determine the imbalance price for: (a) each imbalance settlement period; (b) its imbalance price areas; (c) each imbalance direction. 4. The imbalance price for negative imbalance shall not be less than, alternatively: (a) the weighted average price for positive activated balancing energy from frequency restoration reserves and replacement reserves; (b) in the event that no activation of balancing energy in either direction has occurred during the imbalance settlement period, the value of the avoided activation of balancing energy from frequency restoration reserves or replacement reserves. 5. The imbalance price for positive imbalance shall not be greater than, alternatively: (a) the weighted average price for negative activated balancing energy from frequency restoration reserves and replacement reserves; (b) in the event that no activation of balancing energy in either direction has occurred during the imbalance settlement period, the value of the avoided activation of balancing energy from frequency restoration reserves or replacement reserves. 6. In the event that both positive and negative balancing energy from frequency restoration reserves or replacement reserves have been activated during the same imbalance settlement period, the imbalance settlement price shall be determined for positive imbalance and negative imbalance based on at least one of the principles pursuant to paragraphs 4 and 5.
