According to local sources, Mexico City's Public Transport System (STC) is looking into renovating its electricity grid and streamline its consumption through a Public Private Partnership contract.

The renovation plan will seek to migrate from the network of 23 kilowatts (kW) to 230 kilowatts, which would reduce by up to 35 % its annual spending on electricity consumptio. STC would become a large consumer and the cost per kilowatt would decrease.

Joel Ortega, director of STC, said that this migration would convert Mexico City Metro in the largest consumer of electricity in the city.

The new system would also prevent the rail network from interruptions in the service.

Ortega explained that the project will make use of a public-private partnership with an estimated investment of around US$500 million. The project will be available to international investors to increase competition.

Ortega said that migration could save up to US$50 million per year.
