Private equity giant Riverstone Holdings has agreed to back Avant Energy, a newly-established Mexican energy company, with a line-of-equity investment.

Riverstone will initially provide Avant with a $150 million investment, which can be increased to $300 million once this initial capital has been invested.

Avant executives have also made additional capital commitments for undisclosed amounts.

The newcomer, with offices in Mexico City, Monterrey and Houston, will focus on the development, construction and operation of infrastructure for Mexico’s oil, natural gas, refined products and electricity sectors, as well as participate in the recently liberalised markets for these products and services.
