Accepted offer cashflow/bid cashflow 

The two graphs in the sections below depict the cash flow associated with accepted bids and offers by Period and Fuel Type. It provides an insight into how much balancing actions cost and how the amount is influenced by the time of day and type of BMU used for balancing. Positive values on either graph reflect cost to the system (i.e. payments made to BSC Parties). Negative values show payments made by BSC Parties.
