Teacher Retirement System of Texas has approved two new commitments to Quantum Energy Partners totalling $500m (€419.7m).

The pension fund said it has committed $250m to the Quantum Energy Partners IX fund, and awarded a further $250m to the Quantum Quest SIF separate account it holds with the manager.

According to sources, Quantum is planning to raise $4.5bn for the opportunistic North America energy infrastructure fund Partners IX.

The Quantum Quest SIF separate account will follow a strategy similar to Partners IX, targeting assets across upstream oil and gas, as well as energy transition and decarbonisation sectors.  

Texas Teachers has also committed $25m to Blackstone Voltron Co-Invest, an opportunistic vehicle focused on US assets alongside Blackstone Energy Transition Partners.

Blackstone declined a request for comment.
