Stonepeak has so far raised $1.7bn (€1.6bn) for its latest infrastructure fund, according to an SEC filing in July.

As previously reported, the alternative investment firm is seeking to raise $2.5bn for the Stonepeak Opportunities Fund.

Stonepeak declined a request for further comment.

The Employees Retirement System of Texas told IPE Real Assets that it has made a $75m commitment to the Stonepeak fund.

Stonepeak Opportunities Fund is expected to invest in the US and Europe as it targets mid-market energy transition, transportation/logistics, digital and social infrastructure assets.

So far, Stonepeak has announced that the opportunities strategy has invested C$662.5m (€455.7m) to buy a 50% stake in a Canadian natural gas liquids pipeline system known as Key Access Pipeline System.

An earlier version of this story incorrectly stated that Stonepeak acquired the stake in Pembina Gas Infrastructure.
