PNM picks Aconex to upgrade San Juan coal-fired power plant

Public Service Co. of New Mexico (PNM) picked Aconex to support the environmental upgrade of its San Juan Generating Station.

San Juan is a coal-fired power plant near Farmington, New Mexico, which serves more than 2 million electricity customers. PNM is a regulated utility and New Mexico’s largest provider of electricity.

The environmental upgrade project targets San Juan’s compliance with federal visibility regulations concerning regional haze caused by power plant pollutants. The project, approved by the New Mexico Environmental Improvement Board and subject to the approval of the U.S. Environmental Protection Agency (EPA), would retire two of San Juan’s four coal-fired power generating units by the end of 2017 and install nitrogen-oxide reduction technology at the other two units by early 2016.

The upgrade is expected to control haze-forming and carbon emissions, while reducing water usage and coal combustion byproducts. The estimated value of the multi-year project exceeds $100 million.

PNM will use the Aconex Online Collaboration Platform to manage project information and processes across a multi-company design, engineering and construction team. Different organizations on the team will be able to share documents, drawings and correspondence on a secure, neutral platform for improved efficiency and risk management.
