Clearlake Capital completed its acquisition of Qualus, a Florida‑based power‑grid platform that serves utilities and high‑tech clients. New Mountain Capital sold the company, and no purchase price was disclosed. The deal broadens Clearlake’s presence in energy technology and positions it to benefit from the growing demand for grid‑modernization tools across the United States today.

Qualus, founded in 2001, has built software that helps utilities manage electric services and integrate renewable resources. Under CEO Greg Herasymuik, the company has expanded its customer base beyond traditional utilities to include commercial and industrial users. The acquisition reflects a trend of private‑equity firms targeting infrastructure software to capitalize on the sector’s digital transformation.

The transaction strengthens Clearlake’s portfolio in the energy sector, giving it a foothold in a market projected to reach $200 billion by 2030. Investors will watch how Qualus’s technology integrates with Clearlake’s existing holdings, potentially unlocking cross‑sell opportunities. The deal also signals confidence in the resilience of grid‑software investments amid regulatory pushes for smarter infrastructure.

Qualus’s customer base includes more than 30 utilities and 200 commercial accounts, giving it a diversified revenue stream. By acquiring Qualus, Clearlake can leverage synergies with its other energy‑tech investments, such as software for distributed generation and asset management. The move also aligns with broader industry momentum toward decarbonization across the United States, bolstering long‑term returns today.
