Throughout 2009, ONS consolidated a number of initiatives for risk assessment of its technical and business processes.

Amongst these assessments, the risk assessment developed in the REGER Project (ONS Energy Management Grid) should be highlighted. This risk assessment was conducted based on a methodology created by ONS, based on practices of the PMI - Project Management Institute, for the management of risk of its projects. This initiative has involved approximately forty professionals of the company in the stages of identification and risk assessment, completed in December 2009, and in the definition and prioritization of actions aimed at mitigating the identified risks. This initiative will continue throughout the project development, with the step of monitoring risks and controls.

For the first time since they were created, the Grid Procedures had, in 2009, its approval on a final basis, through ANEEL Resolution No. 372/09 of 08/05/2009. To achieve this result, a broad review of these procedures was necessary, coordinated by the area of risk management and with effective participation of all technical areas of ONS, held in a joint work with ANEEL, motivated by the Public Hearings of the Agency, No. 049 / 2008 and No. 061/2009.
