Eight wind and solar power generation facilities stand out among SI Partners’ operations in Mexico.
SI Partners is an energy subsidiary focused on cross-border infrastructure and liquefied natural gas projects. Following a strategic restructuring, a consortium led by KKR acquired a majority stake, while Sempra retained a minority stake.
SI Partners’ Operations in Mexico
SI Partners develops, builds, owns, and operates renewable energy generation facilities. These facilities have long-term power purchase agreements to sell the electricity generated to their customers. Typically, these customers are on-demand power suppliers, as well as industrial and other types of customers.
On-demand power suppliers sell electricity to their end users and wholesale customers after receiving power from these generation facilities. Industrial and other customers, meanwhile, consume electricity to power their own facilities.

As of December 31, 2025, SI Partners had a total nominal capacity of 1,044 MW. This figure corresponds exclusively to its operational wind and solar power generation facilities. However, the actual power generation from these renewable assets is subject to constant fluctuations resulting from natural conditions.
These variables include wind speed, inclement weather, and actual hours of sunlight. Additionally, some of these facilities could be affected by recent legal and regulatory changes implemented in Mexico.
SI Partners’ capacity includes the ESJ–Phase 1, ESJ–Phase 2, and Ventika wind farms. It also includes Border Solar, Don Diego Solar, Pima Solar, Rumorosa Solar, and Tepezalá Solar.
Other Businesses
SI Partners operates storage terminals for refined products in Mexico through long-term contracts with companies such as Valero and Pemex. It is also building the Louisiana Storage project to support natural gas infrastructure in the United States.
SI Partners owns Ecogas, a regulated company that distributes natural gas in Mexico through thousands of kilometers of pipelines. In December 2025, an agreement was reached to sell Ecogas for 9,000 million pesos.
