The City of Boulder's WRRF completed its Biogas Use Enhancement Project in 2020, producing RNG from the treatment plant's biogas. The RNG is sold to Western Disposal which can fuel up to 38 trucks in it trash collection fleet. Tetra Tech provided engineering, procurement and construction (EPC) services to the Boulder facility which incorporates Tetra Tech's proprietary BioCNG™ gas conditioning system.
The RNG is injected into the Public Service Company of Colorado's pipeline. Boulder also is capitalizing on the sale of RIN credits in the federal Renewable Fuel Standard (RFS) marketplace.

In the Longmont program, a building owner self-reports data into a no-cost, secure U.S. Environmental Protection Agency software program. The building receives output from the software model -- an ENERGY STAR Score -- comparing energy consumption against similar-use buildings in the same climate region.
In 2021, the city plans to make a voluntary program for benchmarking available to all commercial buildings greater than 20,000 square feet in Longmont.

While the pilot program will be open to all businesses, Longmont officials are hoping to spread the $3.2 million-worth of benefits received by the city's commercial power customers in the last two years to more small and minority-owned workplaces. Those savings were realized by Longmont businesses through rebates on 530 energy-efficiency improvement projects completed over the past two years through the Efficiency Works program, which is offered in Platte River Power Authority's four member cities -- Longmont, Loveland, Fort Collins and Estes Park.
The Efficiency Works' rebate programs use funding from the power provider and member municipal utilities for rebates on projects such as converting lighting to LED bulbs, installing high-efficiency air conditioning and heating systems and improving refrigeration systems. The program also encourages urges waste diversions, water use reduction and environmentally sustainable employee transportation recommended by Boulder County's Partners for a Clean Environment (PACE) program.
Throughout Boulder County from 2010 through 2017, the county-funded PACE program has recorded more than $21 million in private investments, matched by $4.3 million in rebates from PACE, toward upgrading the electrical, water, lighting, heating, cooling and waste systems of 1,409 businesses, including 365 in Longmont.
