New Orleans-based energy company Entergy is spending nearly $16.6m to make the energy service in Jackson, Mississippi, safer and more reliable.
This will include low-tech projects such as tree trimming to high-tech ones including conductor replacement. The improvements will harden the system against storms and outages, while also making it more resistant to cyber attacks and physical threats.
“This is part of a multi-year investment designed to strengthen all parts of our grid to help reduce power outages,” said Robbin Jeter, Entergy Mississippi vice president of customer service. “A strong, reliable power grid is critical to our safety and way of life, and it’s necessary for job creation and growth.”
Entergy has completed or is working on the following projects in Jackson:

  • Vegetation management: the company is spending more than $1m to trim vegetation from 430km of line and 32 circuits;
  • Substation work: some $5.2m will be spent, with $3m focused on the downtown area;
  • Equipment replacement: more than $1m will be spent replacing and upgrading existing equipment, and
  • Other projects: changing from copper to aluminium conductors and swapping out wooden poles with stronger composite material is also planned.
Last year, Entergy spent more than $66.5m on reliability projects in its 45-county Mississippi service area. The company’s electrical assets have grown as Mississippi has grown. Today, the company manages more than 32,000km of electrical lines, 291 substations, five natural gas-powered generating plants and one nuclear plant in the state.
Much of this infrastructure has been in place for more than 60 years. While the company has maintained and expanded that infrastructure, eventually the time comes to replace aging equipment with new and improved technology.
