Washington State Investment Board (WSIB) has approved $600m (€566m) worth of investments with Global Infrastructure Partners (GIP).
They include a $400m commitment to Global Infrastructure Partners V, for which GIP is seeking to raise $25bn, according to WSIB.
The pension fund also confirmed to IPE Real Assets that it is expanding an existing separate account by committing a further $200m to Global Infrastructure Partners Cascade I.
WSIB has committed a total of $1bn to the separate account which was set up to hold lower-risk infrastructure assets over the long term.
The pension fund said the new commitments were subject to ongoing due diligence and final negotiation of terms and conditions.
