Nuveen Invests Alongside Lime Rock New Energy and Management to Acquire Power TakeOff

Nuveen’s Private Equity Impact team joins Lime Rock New Energy to acquire Power TakeOff (“PTO”), a software-enabled energy efficiency services company. PTO’s AI/ML-based offerings generate significant energy savings and greenhouse gas emissions mitigation for the traditionally underserved small and medium business (“SMB”) market. The investment aligns with Nuveen’s goal of driving an inclusive transition to a low-carbon economy.

Nuveen will leverage its experience scaling impact-oriented businesses while bringing expertise from its broader real assets and private markets platform to support PTO in the next stage of growth. As part of the investment, Radhika Shroff, Managing Director on Nuveen’s Private Equity Impact team, will join the company’s board of directors and will work collaboratively with the board to manage impact performance while driving the growth of the business.

“Energy efficiency is an essential component of the transition to a low carbon economy, accounting for more than 40% of the emissions mitigation needed by 2040,” said Shroff. “By leveraging Advanced Metering Infrastructure data and artificial intelligence, PTO is tackling this challenge head-on, targeting the SMBs that are often overlooked in the energy efficiency space. We look forward to working with PTO and Lime Rock New Energy, leveraging our expertise in decarbonization and broad real assets platform to address underserved segments and support the company’s next phase of growth.”

Through its partnerships with major utilities across the U.S., Power TakeOff identifies power savings opportunities for SMBs that are delivered virtually and that do not require capital expenditures to implement. PTO’s energy advisors engage directly with SMBs to implement these changes to reduce energy usage. This results in power bills for SMBs that are, on average, 17% lower with a corresponding reduction in CO2 emissions, all at no cost to the SMB customer. Power TakeOff has pioneered a pay-for-performance model that allows utilities to enter into these contracts with minimal risk and generates the type of revenue-aligned impact that Nuveen targets.

“Nuveen’s focus on climate inclusion is directly aligned with the mission of Power TakeOff,” said Peter Widmer, Co-CEO of PTO. “We seek to generate community impact alongside significant energy and emissions savings, and are glad to have found an additional partner in Nuveen who shares that goal.”

Nuveen is a pioneer in impact investing, with a long track record of driving strong financial results and a positive influence for society’s most pressing problems. The Private Equity Impact team seeks to drive an inclusive transition to a low-carbon economy, targeting disruptive businesses that reduce waste and emissions, use resources in a circular manner, and expand access to and reduce the cost of basic products and services for underserved consumers. Nuveen made its first impact investment in the 1980s and now manages over $1.0 billion in private equity impact capital.
