Recently adopted amendments to the Mexican Constitution have a profound effect on all aspects of the electricity sector in Mexico.  Under the amendments, the generation of power is no longer a public service reserved to the state.  Private parties will now be able to generate and sell power in a wholesale market outside the traditional legal structures.  Three agencies will have primary responsibility for the sector.  The Department of Energy (Secretaría de Energía or the SENER) will have the policy function; the Comisión Reguladora de Energía (CRE) will have the regulatory function; and the Centro Nacional de Control de Energía (CENACE), a new decentralized agency, will manage the power grid and the wholesale electricity market.  The generation and wholesale of electricity will take place under a system of open competition.
