Country report

Legal framework

Since the implementation of the 2013 Energy Reform, Mexico has made progress in defining the development of a sustainable, competitive and efficient energy industry. During 2015 and 2016, a new competitive market for hydrocarbons and electricity was created, based on principles of equity, and social and environmental responsibility. In December 2015, an important Law on Energy Transition entered into force in order to regulate the sustainable use of power and Mexico's commitments to clean energies and the reduction of polluting emissions from the electric power industry.

In its drive to diversify its energy mix, Mexico plans to generate 35% of its electricity from clean energy sources by 2024. Under its national, electricity infrastructure development, sectoral programmes, nuclear power is considered to be a clean, competitive source for the supply of electricity and it is to account for a larger proportion of the electricity generated in the country.

Operation of the Laguna Verde reactors

During 2016, the 17th refuelling outage of Laguna Verde unit 1 was extended from its original 65 days to 155 days because of a divisional diesel generator failure. During this outage, the steam dryer was reinforced as part of the extended power uprate (EPU) (120% of the original licensed thermal power) approval. On March 2016, this unit received permission for operation at the new power uprate level from the Mexican Regulatory Authority. The current operating cycle 18 started at this new power level (2 317 MWth, 810 MWe).

Laguna Verde unit 2 performed its 14th refuelling outage as planned in the spring of 2016 and started its second operating cycle (Cycle 15) at EPU power level (2 317 MWth). For both Laguna Verde units, the new EPU licence has not been issued by the Energy Secretariat.

Licence renewal

In 2015, an application for a licence renewal of both Laguna Verde units was submitted to the Mexican Regulatory Authority, which will allow their operation for 30 more years. The unit 1 licence expires on July 2020 and the unit 2 licence expire on May 2025.

Spent fuel storage

In 2015, an independent spent fuel storage installation (ISFSI) started construction on the Laguna Verde site. This installation has not yet been approved by the Mexican Regulatory Authority.
