Bii Hioxo Wind Farm
The Bií Hioxo Wind Farmis a wind power project with capacity for 234 MW of gross electricity output from 117 variable-speed three-bladed wind turbines with a nominal unit power of 2 MW. It entered commercial operation in October 2014 based on a self-supply energy-sales model.
It is located in the municipality of Juchitán de Zaragoza (Oaxaca) and covers an area of 1,892 hectares generally used for crop and livestock farming.
On average, the wind farm avoids the emission of over 420,000 tonnes of carbon dioxide equivalent per year.
Tuxpan III & IV combined cycle power plant
The Tuxpan Power Plant entered commercial operation on 23 May 2003 and is the group’s plant with the largest installed power capacity outside Spain and one of the largest in Mexico. It has apower output of 1,059 MW under a PPA contract with exclusivity for CFE (main contract), plus a net output of 180 MW for selling surplus energy under a self-supply scheme to industrialists and the Wholesale Electricity Market (WEM) under the Electricity Industry Act (LIE), for a total output of 1,239 MW.
It comprises two blocks of similar characteristics. Each block has two Mitsubishi 501F gas turbines, repowered by General Electric, two heat recovery boilers and one steam turbine. Each block produces a power output of approximately 619 MW.
Water is taken from the Gulf of Mexico for cooling and consumption, which is treated in two water treatment plants with strict controls on discharge temperature and metal content, to protect the ecosystem surrounding the power plant.
Norte Durango combined cycle power plant
The Durango Power Plant is the most recent Combined Cycle Power Plant built by GPG Grupo Naturgy in Mexico. It entered commercial operation on 7 August 2010 and operates exclusively on natural gas. The power plant is located on Carretera Federal Nº 40 between Durango and Gómez Palacio at KP 30+115. It includes a plant to treat waste water it receives from the city of Durango, which is some 37 kilometres away from the facility.
The plant has a 2x2x1 configuration, consisting of 2GT + 2HRSG + 1ST. Its two gas turbines (GT) and the steam turbine (ST) were built by Siemens and its heat-recovery steam generator (HRSG) by the Mexican company Cerrey.
The plant has a power output of 450 MW under a PPA contract with exclusivity for CFE (main contract), plus a net output of 105 MW for surplus sale to the Wholesale Electricity Market (WEM) under the Electricity Industry Act (LIE). In total, the plant has a power output of 570 MW.
La Caridad combined cycle plant (O&M)
Grupo México, a mining company with the world’s largest copper reserves and lowest copper production costs decided to construct a 500 MW combined cycled plant in Nacozari (Mexico) to ensure the supply and reduced costs of electricity for its operations in the state of Sonora.
The EPC was awarded to Siemens. Grupo México issued an invitation to tender for the facility’s operations and maintenance, in which six internationally top-level companies took part. Operations and Maintenance Energy (O&M Energy) was selected due to its experience in the operation of combined cycle plants and its knowledge of the country.
Thanks to the experience acquired by Naturgy, O&M Energy provides an owner’s vision as an added value and supports Grupo México beyond the running of the facilities.
The La Caridad Combined Cycle Power Plant is the first third-party facility to be monitored by CESOM, Naturgy’s Operations and Maintenance Supervision Centre, from where all the group’s plants are monitored, taking advantage of the experience acquired in each of these to optimise the management of third-party plants, by comparing results and transferring knowledge.
Naco Nogales combined cycle power plant
The Naco Nogales Power Plant is located in the municipality of Agua Prieta, Sonora, and entered commercial operation in October 2003.
The plant has a power output of 258 MW under a PPA contract with exclusivity for CFE (main contract), plus a net output of 50 MW for selling surplus energy under a self-supply system and 14 MW to the Wholesale Electricity Market (WEM) for a total power output of 364 MW.
It comprises two clearly distinct sections:
A Siemens power plant with a W501G GT and an HE steam turbine.
A waste water treatment plant capable of producing 450 m3/h using water from the city of Agua Prieta.
Hermosillo combined cycle power plant
The Hermosillo Power Plant is the first Combined Cycle Power Plant built by GPG Grupo Naturgy in Mexico. It entered commercial operation on 1 October 2001. It has the unique capacity to start-up with diesel in case there is a natural gas shortage over 10 days of the year. It also has a to treat waste water received from the city of Hermosillo, Sonora.
The plant has a single shaft power configuration consisting of 1Gen + 1GT + 1ST built by Alstom and 1 Heat Recovery Generator built by Duro Felguera. It has a net power output of 270 MW (in winter conditions) under a PPA contract with exclusivity for CFE (main contract) plus 13.5 MW for sale of surplus energy to the Wholesale Electricity Market (WEM) that began on 20 December 2018. This provides a total power output of 283.5 MW.
