From the results of the 2008 meeting in Rio de Janeiro, throughout 2009, with ONS being responsible for the presidency of this group, all the efforts so the VLPGO could be legally instituted were developed, with adequate legal personality. Such objective was reached at a meeting held in October, in Washington, sponsored by MIDISO, with the approval of the "Bylaws of the Very Large Power Grid Operators Association”.

This assured the full and stable functioning of the VLPGO, which became able to contract services, dividing the costs among participating members, besides introducing a policy of exchanging information and knowledge.

The works in 2009 were focused on preparing a specification on Phasor Measurement Units (PMU) and testing the units of potential suppliers. The issues and challenges associated with the integration of renewable sources, HVDC systems in operation and description of global best restoration practices were also identified.

It is important to note that the VLPGO is becoming also a place where leaders of the major operators in the world exchange experiences directly on the performance of their systems and new technologies that have been used, including the share of consultancy costs in projects of common interest, as in the case of PMU studies.
