One month after sending flue gas through the new scrubber stack from Plant Daniel’s unit 1, the plant’s second unit is going through similar testing as the project is on track to be completed under budget and ahead of schedule.

“Unit 2 is actually performing a little better than unit 1 did when it started up,” Engineering Manager Jay Weston said. “We were tuning the process at full load and removing nearly 99 percent of sulfur dioxide emissions.”

The first gas was sent through unit 2 at approximately 8:50 a.m. on Sept. 19.

Vice President of Generation Allen Reaves noted that the recent stretch of dry weather allowed work to catch up on the project’s gypsum pond after a wet summer caused some delays.

“We have finished the gypsum pond,” Reaves said. “We’re finishing up a little bit of drainage in the pond and also finishing some sand work over the liner.”

A byproduct of the scrubbing process is gypsum, which will be piped to a storage pond north of the plant.

Reaves noted the company is preparing to file for a certificate with MDEQ soon and it takes about 30 days to complete that process.

“We’re looking at commercial operation at the end of October or first part of November,” Reaves said.

The project was originally scheduled to be complete in April 2016.

“I appreciate the hard work and dedication of everyone involved in this project,” Plant Manager Nik Budney said. “This project helps meet the challenge of serving our customers’ ever-growing need for energy while working to minimize the impact of electricity production on the environment.”
