The initial public offering by ReNew Power is likely to get postponed after investors showed lukewarm appetite towards the proposed issue, reported The Economic Times on Friday.

The renewable energy firm is yet to receive all regulatory approvals, the report said citing four unidentified sources.

The energy firm was backed by the likes of Goldman Sachs, Abu Dhabi Investment Authority and Japan’s JERA Co, according to the report.

The renewable energy firm in May filed its draft IPO documents with the regulators to raise up to $1 billion.
