this firm's operations and the extension of Electricity Regulatory Commission's (CRE) competencies. Also important is the promotion of private independent power production and the discussion of the role played by Pidiregas (see Financing below) in the financing of large projects. Renewable Energy and Energy Efficiency laws 2008 During the term of president Felipe Calderón, on 28 November 2008 two decrees published in the Official Journal of the Federation created two laws, one addressing renewable energy and the other energy efficiency. The Renewable Energy Development and Energy Transition Financing Law (LAERFTE) mandated the Secretary of Energy (SENER) to produce a Special Program for Development of Renewable Energy (PEAER), and a National Strategy for Energy Transition and Sustainable Energy Use (ENTEASE), to be updated yearly. The main objective of the law is to regulate the use of renewable energy resources and clean technology, as well as to establish financing instruments to allow Mexico to scale-up electricity generation based on renewable resources. SENER and the Energy Regulatory Commission (CRE) are responsible for defining those mechanisms and establishing legal instruments. The following functions are the responsibility of SENER, among others: (a) defining a national program for ensuring a sustainable energy development both in the short and the longer term, (b) creating and coordinating the necessary instruments to enforce the law, (c) preparing a national renewable energy inventory, (d) establishing a methodology to determine the extent to which renewable energies may contribute to total electricity generation, (e) defining transmission expansion plans to connect power generation from renewable energy to the national grid, and (f) promoting the development of renewable energy projects to increase access in rural areas. The CRE is responsible for developing rules and norms regarding the implementation of LAERFTE, including provisions for promotion, production, purchase and exchange of electricity from renewable sources. The CRE, in coordination with the Secretary of Finance (SCHP) and SENER, will determine the price that suppliers will pay to the renewable energy generators. Payments will be based on technology and geographic location. In addition, CRE will set rules for contracting between energy generators and suppliers, obliging the latter to establish long-term contracts from renewable sources. The Sustainable Energy Use Law (LASE) has as its objective to provide incentives for the sustainable use of energy in all processes and activities related to its exploitation, production, transformation, distribution and consumption, including energy efficiency measures. More specifically, the law proposes: The creation
