Entergy Mississippi Inc. Announces $500 Million Investment in Transmission System
Projects represent major investments in customer reliability
Jackson, Miss.–Entergy Mississippi, Inc. today announced its investment of approximately $500 million in upgrading and bolstering transmission facilities within the state between 2006 and 2013.
These projects represent the completion, initiation and planning of major phases in Entergy Mississippi’s comprehensive plan to upgrade, improve and strengthen its transmission system.
From 2006 through 2008, Entergy Mississippi completed and put into service new substations, upgraded substation equipment and upgraded transmission lines representing nearly $90 million in investments. In 2009, that number was more than $38 million.
During the years from 2010 through 2013 the company expects to invest an additional $376 million-plus in further upgrades and expansions. While the number of jobs created is not yet known, these investments represent a positive impact on Mississippi’s economy through dollars spent on both contractors and materials necessary to complete these projects.
“We’re exited about these improvements for many reasons. It shows our commitment to the state and to bringing low-cost, reliable power to our customers,” said Haley Fisackerly, president and chief executive officer of Entergy Mississippi, Inc. “We spent significant time and effort analyzing and designing the most cost-efficient solutions that provide the greatest benefits to our customers, while at the same time helping improve reliability and meeting the power demands the future will surely bring.”
The investments will contribute to customer reliability by providing redundant routes of electrical service so that if there is a transmission line fault, the number of customers affected will be greatly reduced. Additionally, many of these projects provide stronger power ties to alternative sources. By having more sources, new ways to move power and flexibility in the system to adapt to changing conditions, system operators have more ways to provide service under widely varying load conditions.
“These improvements and upgrades are based on carefully conducted planning studies that analyze and anticipate electricity demand,” said Fisackerly.
“These are good examples of wisely planning for the future.”
“These improvements illustrate our commitment to strengthen and expand our transmission system here in Mississippi to meet the new demands of an evolving national energy policy,” Fisackerly added.
Throughout the planning, design and construction phases, Entergy teams worked closely with local and state government officials, permitting agencies, regulatory bodies and communities where these projects were built.
While the company’s transmission engineering and construction group spearheaded these projects, multiple departments within the company worked together to bring these projects to reality. Regulatory, customer service, distribution and economic development employees, among others, all played important roles in getting these projects designed, planned, approved and built.
Projects include new substations, equipment upgrades at existing substations, upgrading transmission lines, new transformers, voltage regulators and other items that will bolster and strengthen the company’s transmission system. Projects are located throughout the Entergy Mississippi service territory. (For a complete listing, see the Entergy Mississippi, Inc. Transmission Projects Facts document.)

Entergy Mississippi, Inc. Transmission Projects Facts
Nov. 24, 2009
Entergy Mississippi, Inc. today announced that it has completed, has in construction or in planning transmission system expansions and improvements that represent an investment of approximately $500 million in upgrades, improvements and new construction over eight years.
This nearly half billion dollar investment is over the years 2006 through 2013.
Below is a list of major upgrades and expansions Entergy Mississippi has made or is planning to make over that time period.
The company has also made or plans to make numerous smaller value upgrades and improvements that collectively represent investment of several hundred million dollars.
2006 — 2008
Twinkletown substation: This substation in DeSoto County added more distribution capacity. It went into service in the summer of 2006 and enhances reliability during summer peak demand. This substation is on the company’s 230 kV transmission line that runs between its Freeport and Robinsonville substations. The project included construction of a 230 kV line, three Entergy feeders and one feeder serving the Coahoma Electric Power Association.
This project represents an investment of more than $6.3 million.
Bozeman Road substation: This facility went into service in 2007 and represents an investment $14 million. This substation provides an additional distribution source in the area west of Madison to accommodate residential load growth.
McComb capacitor bank: This equipment upgrade also went into service in 2007 and represents a $750,000 investment. It provides voltage support and reactive power management in the McComb area.
Plum Point third transformer: Adding this transformer provides additional distribution capacity in Desoto County. This project represents an investment of more than $2 million.
Grants Ferry add second transformer: Provides additional distribution capacity along Lakeland Drive towards Brandon in Rankin County. This represents approximately $1.2 million invested.
Getwell substation - second transformer: Provides additional distribution capacity in Desoto County near Hernando. Investment of $5.3 million.
Natchez D-VAR units: Two dynamic VAR units regulate and stabilize voltage levels by injecting dynamic reactive power into the power grid at precise locations where voltage problems can occur. These two units automatically control local transmission voltage during contingencies and restore voltage to an acceptable level.
Entergy Mississippi chose this technology because it was field proven at locations in Entergy’s Louisiana and Texas operating companies.
These units went into service in 2008 and represent a $10 million investment in improved reliability.
Liberty – Gillsburg 115 kV transmission line: This upgraded transmission line, completed in 2008, represents an investment of $7 million. It improves transmission flow between Entergy Mississippi and Entergy’s Louisiana operating company and illustrates the systemic nature of the 15,500 mile transmission system which is interconnected across four states.
2009 – 2011
Liberty – Gloster 115 kV transmission line: This upgraded transmission line went into service recently in May. This project, an investment of more than $4 million, is associated with the equipment upgrades at the Natchez substation.
Indianola – Greenwood 115 kV transmission line: This transmission reliability improvement project is scheduled to be in service next year. Investment in this project should be approximately $250, 000.
Sunnybrook substation and radial 115kv transmission line: This $28 million project, slated to go into service in 2011, will provide additional distribution capacity to serve commercial and residential growth in the Ridgeland area.
2012 – 2013
Granada/Winona/Greenwood improvement project: Five 115 kV lines serve the Greenwood, Winona and Grenada area in north central Mississippi. Under several single contingency scenarios, including loss of the 230/115kV auto transformer at Tillatoba and/or the loss of the Tillatoba to Grenada 115kV line, various substations in this area would have low voltages. This project will address those potential voltage losses. The investment in this reliability improvement is expected to be about $44 million. The scheduled in service date is 2012.
Church Road substation and 11.3 mile 230 kV transmission line: Building this new substation and transmission line will provide additional distribution capacity to support residential and commercial load growth south of Horn Lake. The project is scheduled to go into service in 2012 and is projected to require an investment of approximately $ 33.8 million.
Ray Braswell – Wyndale 115 kV transmission line: This project will improve the reliability of the 115kV line from South Jackson to Brookhaven by adding a new power source south of Byram. It will also provide additional distribution capacity to support residential, commercial, and industrial load growth between Jackson and Brookhaven.
The investment value of this project is expected to be about $45 million.
