The Teachers’ Retirement System of Louisiana (TRSL) has committed $100 million to infrastructure funds, including vehicles managed by Blackstone and I Squared Capital. The commitment is split evenly, with $50 million directed to Blackstone Energy Transition Partners V and $50 million to ISQ Global Infrastructure Fund IV, according to a report from Institutional Real Estate.
Blackstone Energy Transition Partners V is a closed-end, opportunistic strategy that invests in energy companies building enterprises to support cleaner, reliable and affordable energy. A fundraising target has not been disclosed. The Teacher Retirement System of Texas committed $200 million to the same fund in June. Blackstone Energy Transition Partners IV, the predecessor vehicle, closed with $5.6 billion in total capital in 2025. ISQ Global Infrastructure Fund IV, a vehicle of I Squared Capital, is a closed-end, value-added, opportunistic fund investing in brownfield, renewable energy, transportation and utilities in Europe and the United States.
The commitment suggests TRSL is maintaining or expanding exposure to infrastructure and energy transition strategies through established managers. The presence of a $200 million commitment from the Teacher Retirement System of Texas to the same Blackstone fund indicates broader institutional interest in the vehicle, though the dossier does not provide a fundraising target or total capital raised to date for the current fund.
What remains unknown is the timing of the commitments, TRSL’s total infrastructure allocation, and whether additional commitments to other funds were made as part of the same slate. The source is a single secondary summary, and no primary TRSL board materials or manager statements are included in the available evidence.
