Impact assessment of efficient lighting and appliances project

EXPERTISE : , Energy Efficiency and DSM Programs

Mexico is the second largest emitter of Greenhouse Gases (GHG) in Latin America. In order to achieve targets of higher efficiency and diversification of the energy matrix, the World Bank has supported activities in Mexico intended to increase the penetration of more efficient technologies in the consumption of energy in the residential sector. Within this context, the Government of Mexico has undertaken a program intended to achieve higher energy efficiency. The Efficient Lighting and Appliances Project (PEE, by its Spanish acronym) forms part of the investment plan for Mexico of the Clean Technology Fund and it was endorsed by its Committee in January 2009. Component 1 of the PEE financed, in part, the distribution of self-ballasted compact fluorescent lamps for use in the residential sector. This program started on May 10, 2011 and ended on September 5, 2012. Component 2 offered a program for the replacement of refrigerators and air-conditioners, including subsidies and financing, from April 2009 to January 2013.
SENER commissioned Econoler, in cooperation with Brain Research, to assess the impact of PEE, particularly its Components 1 and 2, in order to be able to identify the benefits derived from the adoption and acceptance of more efficient technologies, energy and environmental impacts, as well as side effects due to the actions implemented by the PEE and its Components 1 and 2.The main findings of the evaluation of the two programs were the following:
  • The energy impacts did not reach the savings expected for the Appliances program while for the lighting program, the energy and demand savings reached the expectations.
  • The environmental impact was almost 2 million of TCO2 for Component 2 of the PEE and 13.6 million of TCO2 for Component 1 over the equipment’s lifetime.
  • The PEE had several collateral impacts such as direct employment, revenue for the Mexican economy, electricity bills reduction, and reduction of governmental subsidies.
  • The two components are well known and provided information on energy efficiency in Mexico.
  • The recommendations to improve the impact of such programs in Mexico dealt with the program process, evaluation process, program design, database, disposal of equipment and stakeholders training.


  • To analyze and revise the documents of the PEE delivered by the operators and partners of the program
  • To develop an assessment plan of the impacts and of the market
  • To design the data collection tools
  • To develop the surveys for beneficiaries and non-beneficiaries
  • To develop the survey guidelines of the partners of the PEE
  • To collect external data through telephone surveys
  • To interview relevant entities
  • To analyze the results of the data collection
  • To develop the data base of participants
  • To assess the impacts of Components 1 and 2 of the PEE:
    • To develop the baselines of self-ballasted compact fluorescent lamps, refrigerators and air-conditioners
    • To calculate the net and gross savings
    • To define the environmental impacts in terms of GHG
    • To establish the side impacts through a macroeconomic analysis, a study of the effects of direct employment and economic distribution, an analysis of the socio-economic benefits, a calculation of economic savings due to reduction of energy consumption and deferral of the investment of electrical infrastructures.
  • To assess of the market of the PEE:
    • To analyze with a statistical approach the beneficiary and non-beneficiary populations
    • To analyze the causal effects of the PEE
    • To analyze the transformation of the market caused by the PEE
  • To evaluate the cost-effectiveness of the PEE
  • To give recommendations about future programs for the reduction of energy consumption in the residential sector in Mexico.
  • To present the evaluation process and the main findings in a workshop
