In 2009, the settlement of transmission services and charges involved 256 agents, with 66 transmission utilities and 190 grid users, and totalized an amount of R$ 10.550.0 million, with R$ 8.691 million related to the Main Transmission Grid (82% ), R$ 1.242 million of the border grid (12%) and R$ 617 million related to sector charges (6%).

Also in 2009, the implementation of ANEEL Resolution No. 270/07, which aims at improving the quality of transmission services with the introduction of penalties due to equipment unavailability (PV), was consolidated. In July, the first cycle of PV evaluation was concluded. In order to do so, it was necessary the analysis of 6,087 events from July 2008 until June 2009, resulting in a reduction of revenue to the transmission utilities of 0.58%. The implementation of this criterion will surely bring relevant benefits to the BIPS, especially with regard to increasing the availability of its installations.
