NorthWestern Energy Engineers Support Literacy Through United Way of Yellowstone County’s United We Read Event
Date: Apr 15, 2026
TYPE: News
Billings, Mont. – April 15, 2026 – NorthWestern Energy was honored to participate in the annual United We Read event organized by United Way of Yellowstone County, sharing the joy of reading with local students at Billings‑area schools.
As part of the event, NorthWestern Energy’s Cody Lux and Tanner Emerick volunteered time to read to second‑grade students. Reading plays a critical role in developing language skills, strengthening brain function, and sparking curiosity and imagination in young learners.
“Getting the chance to read with students in our community is really special,” said NorthWestern Energy Construction Superintendent Cody Lux. “Early literacy helps kids build confidence, curiosity, and a love for learning, and it’s rewarding to be a small part of that.”NorthWestern Energy is proud to support initiatives that invest in education and help build brighter futures for local children.
“Supporting reading programs like United We Read is an easy way to make a meaningful difference,” said NorthWestern Energy Engineer Tanner Emerick. “We’re proud to partner with United Way and help encourage the next generation right here in Billings.”
United Way of Yellowstone County’s United We Read event brings together volunteers from across the community to promote literacy and inspire a lifelong love of reading among young students.
In 2025, NorthWestern Energy employees donated more than $93,000 to local United Ways across the company’s service territory. To further amplify that impact, NorthWestern Energy matched employee contributions with more than $46,000 in additional company support.
Last year NorthWestern Energy provided more than $2.1 million in donations, sponsorships, and other support for the communities we serve, where our employees work, live and raise their families, including more than $163,000 in donations to organizations in recognition of our employees’ volunteerism.
