The National Electric System Development Program, or PRODESEN, is the main tool to plan and design the electric infrastructure Mexico will need to cover its energy demand, on a 15-year period, following the country’s objectives of efficiency, quality and reliability of the National Energy System, or SEN, as well as its commitment with the country’s Clean Energy Goals.

Its latest version, covering the 2017-2031 period, was published on June 7th on the official webpage of SENER, and can be downloaded here.

To foresee the future, PRODESEN needs to look back in order to succeed. In this blog, we summarize the most important current facts and figures of Mexico’s energy sector, as well as the expected maximum energy demand for the period of 2017-2031.

All the information presented in this blog was used to create the Indicative Program for the Installation and Retirement of Electric Plants, or PIIRCE, and the Expansion and Modernization of the National Transmission and General Distribution Grids, by SENER and CENACE respectively. Both are included as conclusion on PRODESEN’s chapters 4, 5 and 6, and will be further discussed in an upcoming blog.

Mexico’s energy market

  • Since the electrical industry is a necessity for any daily and economic activity, in 2016 showed a greater growth in its GDP, compared to Mexico’s GDP, reaching a growth of 3.5 percent (See figure 1).

  • Mexico’s total energy consumption in 2016 was supplied 18 percent by electricity, second biggest energy provider after petroleum products (See figure 2).

  • The first two long-term electricity auctions were a success. The first one (SLP-1/2015) assigned 84.9 percent of the power generation and 84.6 percent of the CELs requested. The second one (SLP-1/2016) assigned 87.3 percent of the power generation, 87.3 percent of the CELs and 80.1 percent of the requested power.

Mexico’s installed capacity

  • On 2016 the SEN had 73.5 GWs installed, showing an 8.1 percent increase as of 2015, 71.2 percent of it corresponding to conventional thermal units and 28.8 percent to clean technologies.
  • For the same year, 58.9 percent of this installed capacity corresponded to CFE units, 18 percent to PIEs and 23.1 percent to private schemes such as self-supply, cogeneration and non-connected rural, among others.

Mexico’s electric energy production

  • On 2016, 319,634 GWh were produced, showing a 3.2 percent increase as of 2015, 79.7 percent of it corresponding to conventional thermal units and 20.3 percent to clean technologies.
  • Of the generated energy, 54.7 percent corresponded to CFE units, 27.8 percent to PIEs and 17.5 percent to private schemes

Energy transmission and distribution

  • In Mexico, energy is transmitted through the National Transmission Grid, or RNT, at tensions equal or higher than 69 kV. The RNT consists of 53 regions, 45 of them conform the Interconnected National System, or SIN, and are interconnected by 63 links; 4 correspond to the Baja California System and are connected through 3 links; 3 correspond to the Baja California Sur System and are connected through 2 links; and the last isolated one is called Mugelé (see map 1).

  • The SIN has a total capacity to transport 72,450 MWs, while the isolated systems can transport 1,758 MWs. In total, both systems make-up for 104,133 km of lines.
  • Mexico has 13 international interconnections, of which 11 are with the U.S, one is with Guatemala and one is with Belize.
  • Electric power, with a voltage less than 35 kV, is distributed through a system called the General Distribution Grid, or RGD. The total length of the RGD is of 831,087 km and offers service to 40.8 million users.
  • Mexico consumed a total of 298,792 GWh of electricity in 2016.
  • Mexico expects an average annual increase in demand of 3 percent in the SIN for the period 2017-2031 (see map 2)
