May 15 (Reuters) - Energy company ERock disclosed nearly a 32% jump in quarterly revenue as it filed for a U.S. initial public offering on Friday, seeking to tap renewed investor interest in new listings.

The IPO market is showing signs of recovery, encouraging companies to test investor appetite after market volatility and geopolitical uncertainty weighed on new listings in March.

The Houston, Texas-based company reported revenue of $31.7 million for the quarter ended March 31, compared with $24.1 million a year ago. It posted a net loss of $17.2 million, versus a loss of $15.9 million a year earlier.

ERock designs, deploys and operates modular natural gas-powered distributed power systems for data centers, utilities and industrial customers.

The company aims to list on the New York Stock Exchange under the symbol "EROC".

Morgan Stanley and J.P. Morgan are the joint lead book-running managers for the offering.
