It all began with Sawdust

The Entergy story began with a pile of sawdust and a handshake. The sawdust belonged to H. H. Foster, president of the Arkansas Land and Lumber Company. The handshake was between Foster and Harvey Couch, president of Arkansas Power Company.

Couch was an entrepreneur who lived in Arkansas at the turn of the 20th century. He invested in a phone company, radio station, railroad and his biggest success, an electric power company. On Nov. 13, 1913, with a $500,000 line of credit and a franchise to provide electricity to the Arkansas towns Malvern and Arkadelphia, Couch shook hands with H. H. Foster for his sawdust. Couch would use sawdust from Foster’s lumber company as fuel to generate electricity for his power company. It was a new beginning for Harvey Couch and electric service in the state.

Couch’s ultimate goal was to have an integrated electric system with numerous sources of power at a reasonable price. Service reliability was foremost on his mind. He knew if he could provide a reliable product at a good price he would succeed. With the fuel source secured, Couch began work on electrifying the state.   

On Dec.17, 1914, Malvern and Arkadelphia were lit up as the generators at the lumber company were turned on for the first time. Now called Arkansas Light and Power Company, Arkansas’ newest endeavor to bring the benefits of electricity to the rural south began with two 550 kilowatt generators and 22 miles of transmission lines.

Couch’s company grew rapidly. Ten years later he completed construction of the Remmel hydroelectric dam on the Ouachita River. His transmission system now covered 300 miles. With a 9,000 kilowatt generator in place, Couch set his sights beyond the state’s boundaries. 

Couch began acquiring independent electric properties in Jackson, Vicksburg, Columbus and Greenville, Miss. His plan was to develop an interconnected system much like the one in Arkansas, but between states. On April 12, 1923, Mississippi Power and Light Company was incorporated in Mississippi.

 The fuel and electricity for this new company would come from Louisiana. The Louisiana Power Company was formed so Couch could take full advantage of the abundant supply of natural gas found in northern Louisiana. In November 1925, Couch’s Sterlington generating station was placed online. The largest power plant south of St. Louis, its 30,000 kilowatt capacity was owned by three companies: Arkansas Light and Power, Mississippi Power and Light, and Louisiana Power Company.

At the dedication of the Sterlington plant, Gov. Harvey Parnell of Arkansas said, “Harvey Couch has done more to develop these three states – Louisiana, Arkansas and Mississippi – than any other man.” Couch’s goal of an integrated electric system was becoming a reality.

Elsewhere, the competition to electrify New Orleans was fierce. Electric lighting had been introduced there at the 1884 Cotton Centennial Exposition, but high costs, fear and unreliability were obstacles to electrifying the city. In the early 1900s, nine separate electric companies competed in New Orleans. Nearly all were small, isolated generators that served limited areas, operated on different voltages and used various kinds of equipment. None were interconnected, even within the city.

Electric Bond and Share – The Competition

Sidney Mitchel worked for Electric Bond and Share Company, which was owned by General Electric. EBASCO was building, financing and operating struggling new electric systems. By the early 1920s Mitchel had acquired all the electrical service in New Orleans and was expanding in other places including Little Rock and Memphis.

Like Couch, Mitchel knew the only way to grow his company was to expand. Soon EBASCO was competing directly with Couch as their expansion overlapped in Arkansas and Louisiana. Both men knew that they could not continue competing for territory so in 1925 they joined forces, consolidating their properties into one large, interconnected system. The new system was Electric Power and Light Corporation, owned by EBASCO and run by Couch. The system that would become Entergy was born.

The Great Depression that began in 1929 brought hard times, reduced sales and shriveling capital markets to utilities. The Electric Power and Light Corporation was no exception. Then MP&L president Rex Brown described company operations during the era: “Stockholders had to be continually assured that their investments were safe. At the same time, they had to be convinced that dividends, while in arrears, would eventually be paid. Our customers, hard-pressed for finances as our company, could not pay higher rates or increased utilization. In fact many discontinued service because they had to choose between electricity and food. The meeting of payroll was a continuous nightmare for company officers.”

Despite the hardships, AP&L, MP&L, LP&L, and New Orleans Public Service, the company serving the New Orleans area, made it through intact. Some of the nation’s largest utilities did not. 

The Public Utility Holding Company Act

Samuel Insull was Thomas Edison’s business secretary. He moved to Chicago to build a multilevel utility organization that included holding companies, which held other holding companies. The profit-taking opportunities inherent in his pyramid scheme set off a national acquisition craze. By 1932 there were eight holding companies controlling 73 percent of the investor-owned electric business. The scheme collapsed and public outcry produced the Public Utility Holding Company Act of 1935.

PUHCA broke up the multilevel holding companies and required them to register with the U. S. Securities and Exchange Commission. The companies were required to specialize in one service and relinquish their non-related properties. EBASCO was one of those companies.

In 1949 EBASCO’s Electric Power and Light Corporation was dissolved. In its place, Middle South Utilities, Inc., Entergy former name, was formed as a holding company for Arkansas Power and Light, Louisiana Power and Light, Mississippi Power and Light, and New Orleans Public Service, Inc. By special request of New Orleans officials, NOPSI was allowed to keep its gas and transit operations in the city.

In MSU’s 1949 annual report, the company’s first president, Edgar Dixon, noted in his letter to shareholders that the year was “one of growth and progress for the companies of the Middle South System.” He reported that the company was paying a dividend of 27.5 cents a share to more than 25,000 stockholders “who reside in every state of the country and in 24 foreign countries.” At the end of its first year of operations, MSU served over 625,000 customers in more than 1,600 communities.

Two decades of growth

The 1950s and 1960s were decades of growth and prosperity for the company. Capacity grew with demand and the system met all challenges and opportunities. The system’s largest generating station, gas-fired NineMile Point near New Orleans, came online in the 1950s. Little Gypsy, located on the Mississippi River upriver from New Orleans, became the world’s first fully-automated generating unit in 1961.

Edgar Dixon died in 1962 and was succeeded by Gerald Andrus. As MSU’s second president, Andrus’ first major achievement was the creation of the service company, Middle South Services, Inc. (now known as Entergy Services, Inc.) in 1963. The company provided the common services, finance, tax, engineering, communications and human resources support for all five MSU companies.

In 1965 the system was hit by Hurricane Betsy, then the worst storm in the company’s history. Betsy destroyed the southeastern end of the system. In the New Orleans area, 90 percent of the system was damaged or destroyed. All of Louisiana Power and Light’s customers in southern Louisiana were without power. With help from their sister companies and neighboring utilities, nearly all customers were restored within nine days. LP&L’s publication Fifty Years of Service noted at the time that Hurricane Betsy had inflicted “the greatest weather-related damage to a single utility.”

In 1968 the system entered the nuclear age when Arkansas Power and Light was granted a construction permit to build Arkansas Nuclear One Unit One near Russellville, Ark.

By the end of the 1960s, Andrus reported in the annual report that the number of customers had grown to more than 1 million. Generating capacity, primarily using oil and gas, had grown, too. But this period of rapid expansion came to an abrupt halt in the 1970s as a result of the 1973 OPEC oil embargo.

The system responded by continuing to diversify its fuel mix. In 1970, LP&L announced plans for its Waterford 3 nuclear unit near Taft, La. Two years later, Mississippi Power and Light announced plans for the Grand Gulf Nuclear Station near Port Gibson, Miss. The same year, System Fuels Inc. was formed to buy fuel for the entire system. This centralized method of fuel procurement meant lower prices and better rates for consumers.

Fuel - Diversity and Supply

Gerald Andrus retired in 1974 and Floyd Lewis became the third president of MSU. His major task was to deal with the effects of higher fuel prices and uncertain availability. Consumers were quick to respond and conservation became the order of the day.

The effects of conservation began taking their toll on electricity demand. While the system was building new plants based on previous forecasts, the demand for additional capacity did not materialize. The system canceled plans for additional units and began marketing efficiency to help customers with rising bills. Some plants could not be canceled and the public's reaction to paying for these additional units embroiled the system in controversy.

In 1980, the system's first coal-fired unit came on line. The White Bluff steam electric station, located near Pine Bluff, Ark., made Arkansas Power and Light the first system company to use all five major electricity-generation fuel types: oil, gas, coal, nuclear and hydroelectric.

Five years later, Grand Gulf One entered commercial operation, as did LP&L's Waterford 3 nuclear plant. While the customers of LP&L were responsible for paying for Waterford 3, precisely who would pay for Grand Gulf One and the two-thirds complete Grand Gulf Two was still in question. The system was in the middle of troubled times.

New Company Name – New Direction

To face the challenges ahead, the company officially changed its name to Entergy Corporation at the annual meeting of stockholders in May 1989. The new name was used to forge a new direction. The name Entergy is a composite of the words “enterprise,” “energy” and “synergy,” three qualities that described the company’s new approach to navigating the rapidly evolving marketplace.

The 1990s were a decade of change. Change was everywhere. The electric utility industry began to prepare for open markets and deregulation. Entergy changed to meet the demands of its stakeholders. New subsidiaries were created to help control costs and increase revenues.

Entergy Operations, Inc., and Entergy Power, Inc., were born in 1990. Entergy Operations streamlined the management of nuclear facilities. Entergy Power was created to tap the growing, potentially lucrative new market of wholesale electricity generation. While these new ventures were taking shape, the utility business was expanding as well.

On June 8, 1992, Entergy announced its plan to acquire Gulf States Utilities, which provided electric service to customers in southeastern Texas and southwestern Louisiana. It took 19 months to work through the merger’s legal and regulatory processes.

Entergy emerged as one of the largest electric utilities in the country with more than 2.3 million retail customers and $22.9 billion in assets. The service area for Entergy utilities now encompassed four states and reflected a major step in making the company more efficient and competitive.

Competition was not limited to the United States. In the mid 1990s Entergy adopted a global vision. The company played a major role in the Energy Policy Act of 1992. “Our people were an important resource to those in Congress who led passage of this milestone legislation, which changed the structure of the electric utility industry, along with federal policies governing the generation and sale of electric power. We consider the legislation a victory for Entergy,” wrote Ed Lupberger, Chairman and CEO, in the 1992 annual report.

The Energy Policy Act provided for wholesale generators, allowed the FERC to order utilities to sell wholesale power, permitted utility holding companies to own properties in foreign countries, and adopted a streamlined process for licensing nuclear plants.

With the freedom afforded Entergy by the Energy Policy Act, the company moved beyond the limitations of its four-state service area and began a major reorganization and expansion effort. It diversified into a number of different industries including energy efficiency, telecommunications and home security. Entergy bought or established foreign generation and distribution entities in Australia, Argentina, Chile, China, Pakistan, Peru and the United Kingdom. The company had become a global player in the electric energy business. But big changes lay ahead.

Back To Basics

Disappointing financial performance in 1997 and early 1998 led to a change in executive leadership. Chairman and CEO Edwin Lupberger resigned in May. Bob Luft, a director and retired Dupont Co. executive, became chairman and acting CEO. The company headed in a new direction: back to basics.

Taking a long hard look at itself, Entergy decided to focus on its core business. It identified the domestic utility business, global power development and nuclear power operations as its three areas of emphasis. Within six months Entergy divested itself of all properties and businesses that did not have a role in these three areas. Near the end of the year a major financial turnaround began and soon afterward J. Wayne Leonard, who had served as president and Chief Operating Officer, was named Chief Executive Officer.

As the new millennium passed without any impact on the system, the company continued to improve and develop its back-to-basics strategies. The change set Entergy on a path to achieving 13 straight quarters of better than projected earnings, a credit upgrade and generally positive buy recommendations by Wall Street analysts across the board.

Entergy's domestic utility business served 2.7 million customers. In 2000 the company recorded the biggest improvement in customer satisfaction in the industry. At the same time, it had the best safety record in the company's history with a great decline in lost-time accidents. All this was in spite of the worst weather the system had experienced up to then.

The Entergy service area is prone to all types of weather. During any year the system may be exposed to extreme cold and heat, tornadoes, hurricanes, hail, snow, ice storms, high winds, lightning, heavy rains and flooding. Everything nature has to throw at electric utilities happens in the Entergy system, sometimes all in the same year.

The summer of 2000 was the hottest and driest on record. It was followed by severe, back-to-back ice storms in Arkansas and northern Louisiana on Christmas Eve and New Year's Eve. Both were described as "hundred year" storms. Then, in 2005 hurricanes Katrina and Rita, among the greatest natural disasters in U.S. history, delivered an unprecedented one-two punch to Entergy's customers and infrastructure in the South. Three years later, hurricanes Gustav and Ike again tested the company and its communities. The year 2009 began with ice storms in Arkansas that disrupted power to more than 100,000 customers. More recently the utility companies have responded to Hurricane Isaac, as well as to severe winter storms and damaging tornadoes. In all cases employees met the challenges of restoring service and improving reliability.

The company's corporate headquarters returned to New Orleans in mid-2006, after nine months in Jackson, Miss., as a result of Hurricane Katrina. Entergy also announced a new principal-offices concept designed to locate some business-critical functions in other cities. A facility in Hammond, La., now houses employees working on certain financial, human resources, and customer billing high-volume transaction processing tasks for customers and employees. The company also located one of its two primary computer data centers in Little Rock, Ark.

In 2005, Entergy added to its fossil generation by purchasing the dual-unit, 718-megawatt Perryville Plant near Monroe, La. In 2006, the company purchased the 480MW Attala Energy Facility near Kosciusko, Miss.; in 2008 Entergy purchased both the 322MW Calcasieu Generating Facility in southwestern Louisiana and the Ouachita Plant, a 789-megawatt generating facility near Monroe. In 2011 the company completed the acquisition of Unit 2 of the Acadia Energy Center, a 580-megawatt generating unit located near Eunice, La. In addition, Entergy purchased the 620MW Hot Spring Energy Facility Located near Malvern, Arkansas, and the 450MW Hinds Energy Facility in Jackson, Miss. In 2014, the company announced plans to purchase Union Power Station. In 2015, the company formally dedicated a new, 550MW natural gas unit at the existing Ninemile Point plant in Westwego, La., and announced plans to build the St. Charles Power Station along the Mississippi River industrial corridor. The same year, Entergy Wholesale Commodities announced the sale of the Rhode Island State Energy Center, an approximately 583-megawatt, natural gas-fired combined-cycle generating plant in Johnston, R.I., that Entergy had purchased in 2011. In 2016 and 2017 Entergy made progress toward adding to and modernizing its power generation fleet: Entergy New Orleans proposed construction of New Orleans Power Station in New Orleans East; the Louisiana Public Service Commission approved construction of the 994-megawatt Lake Charles Power Station, a natural gas-fired combined cycle power plant in Westlake; the Public Utility Commission of Texas approved construction of the Montgomery County Power Station, Entergy’s first new generation project in Texas since 1979.

At the end of 2007, the Louisiana Public Service Commission approved Entergy Gulf States' proposal to divide itself into two separate operating companies in Louisiana and Texas. The separation increased the number of operating companies at the domestic utility level from five to six: Entergy Arkansas, Entergy Gulf States Louisiana, L.L.C., Entergy Louisiana, L.L.C., Entergy Mississippi, Entergy New Orleans and Entergy Texas.

In mid-2015, the Louisiana Public Service Commission approved Entergy's proposal to combine Entergy Gulf States Louisiana and Entergy Louisiana. In addition, the New Orleans City Council approved the transfer to Entergy New Orleans of approximately 22,500 electric customers in the Algiers area of the New Orleans area who were previously served by Entergy Louisiana.

Entergy Corporation and ITC Holdings Corp. announced in December 2011 a proposal for Entergy to divest and then merge its electric transmission business into ITC. In December 2013 the companies discontinued pursuit of the transaction after some of Entergy's retail regulators declined to approve it. Also at the end of 2013, Entergy successfully completed its transition to the MISO regional transmission organization.

In January 2019, Entergy began a multiyear deployment of new, advanced meters for customers' homes and businesses. The rollout of meter installations began in Little Rock – about 50 miles from Malvern, Arkansas, where Entergy's history began in 1913. By the end of 2021, the company plans to deploy advanced meters across our entire system to approximately 3 million customers. Advanced meters facilitate operational efficiencies, enable faster outage response, and empower customers with information to better understand and manage their electricity usage.

Nuclear Power

Having demonstrated its expertise at owning and operating the nuclear plants it built in the South, in 1998 Entergy formed a nuclear business development group, headquartered in Jackson, Miss., to pursue a growth strategy in areas outside the company’s utility service area. The group’s goal was for Entergy to become a leading national operator of nuclear power plants.

The following year, the company purchased Boston Edison’s Pilgrim Station, the first ever U.S. nuclear plant sale by a utility. Entergy Nuclear then purchased Indian Point unit 3 (2000) and the James A. FitzPatrick plant (2000) from New York Power Authority, Indian Point unit 2 from Consolidated Edison (2001) and Vermont Yankee from its 12 owner companies (2002). In 2003, Entergy began providing management services to Nebraska Public Power District for its Cooper Nuclear Station. In 2007, Entergy purchased the Palisades plant in Covert, Mich. from Consumers Energy.

In addition to buying and operating plants, the company also has expertise in decommissioning nuclear plants.

Entergy Nuclear operates five units in the Entergy utility service territory including:

  • Arkansas Nuclear One Unit One and Unit Two – Russellville, Arkansas
  • Grand Gulf Nuclear Station – Port Gibson, Mississippi
  • River Bend – St. Francisville, Louisiana
  • Waterford 3 – Taft, Louisiana

Outside the traditional Entergy utility service area, the company also owns and operates:

  • Indian Point Energy Center Unit Three – Buchanan, New York
  • Palisades – Covert, Michigan

Entergy also provides management support for the Cooper Nuclear Station near Brownville, Nebraska.

The company is playing a major role in the relicensing of nuclear plants. In June 2001, the company’s Arkansas Nuclear One Unit One plant received a new lease on life as the plant was licensed to operate until 2034. This is a major achievement for Entergy and not only contributes to the company’s power needs, but its other initiatives as well. In addition, in December 2018, the NRC renewed the Waterford 3 plant's license to 2044 and the River Bend plant's license to 2045. The company now offers license renewal services across the nuclear industry. Adding another 20 years to each plant’s operating license makes sense because nuclear energy is now the lowest cost way to generate electricity – without emitting any air pollutants or greenhouse gases that may worsen climate change.

In 2013 the company announced plans to close Vermont Yankee at the end of 2014. Vermont Yankee was removed from the grid Dec. 29, 2014, marking the end of 42 years of safe, secure and reliable operations. In the years since then, Entergy has followed a strategy to reduce risks and shrink the footprint of the Entergy Wholesale Commodities merchant nuclear power business. In 2015, the company announced plans to permanently close the Pilgrim Nuclear Power Station no later than 2019. In December 2016, the Federal Energy Regulatory Commission approved Entergy’s sale of FitzPatrick to Exelon, and Entergy announced plans to close Palisades Power Plant in 2018. However, in September 2017, the company revised that plan and announced it will continue to operate the Palisades plant until spring 2022 under the existing power purchase agreement. In March 2017 Entergy completed the sale of FitzPatrick to Exelon. In January 2017, the company announced that after more than four decades of providing New York state with clean, safe and reliable electricity, we planned to close the Indian Point Energy Center Unit 2 in 2020 and Unit 3 in 2021. The early and orderly shutdown is part of a settlement under which New York state agreed to drop legal challenges and support renewal of the operating licenses for Indian Point. In April 2019, the company announced plans to sell the subsidiaries that own Indian Point Units 1, 2, and 3 to a Holtec International subsidiary for decommissioning.

In November 2016, Entergy agreed to sell Vermont Yankee to NorthStar Group Services for accelerated decommissioning. The NRC approved the proposed license transfers in October 2018. The Vermont Public Utility Commission approved the sale in December 2018, and the sale was completed in January 2019. In August 2018 Entergy agreed to sell the subsidiaries that own the Pilgrim and Palisades nuclear plants, after their shutdowns and reactor defuelings, to a Holtec International subsidiary for accelerated decommissioning. The sales include the transfer of the licenses, spent fuel and nuclear decommissioning trusts, as well as the site of the decommissioned Big Rock Point Nuclear near Charlevoix, Michigan, where only the independent spent fuel storage installation remains. The transactions were subject to conditions to closing, including approvals from the U.S. Nuclear Regulatory Commission of the license transfers. Pilgrim shut down in May 2019. In August 2019 the NRC approved the license transfer to Holtec, and the same month the sale of Pilgrim was completed.

In 2007, the NRC granted the company the early site permit for a second nuclear unit at Grand Gulf in Port Gibson, Miss. An early site permit certifies that the site is suitable for a new nuclear unit and resolves many safety and environmental issues related to the site.

Although Entergy has not yet made a final decision to build a new nuclear plant, the company’s business development group is working to preserve the option if nuclear is determined to be the best choice for customers and investors. As part of the NuStart consortium, Entergy Nuclear in 2008 submitted to the NRC an application for a combined construction and operating license for a possible new unit at the Grand Gulf site. NuStart’s efforts are cost-shared as part of DOE’s Nuclear Power 2010 program. On its own, Entergy Nuclear in 2008 submitted an application for a combined construction and operating license for the River Bend site. Currently, Entergy is exploring nuclear plant designs that can be applied to licensing work done to date to best serve the company's customers.

In 2007 Entergy announced a plan to spin off its non-utility nuclear business and create a new, independent company, Enexus Energy Corporation, and EquaGen, a nuclear services joint venture with Enexus. In April 2010, after several regulatory delays and a ruling by the New York Public Service Commission to reject the spin-off, Entergy made the decision to unwind the business infrastructure associated with the proposed new companies.

Today and Beyond

Throughout its history, Entergy has been a major source for economic development throughout its service territory, which includes some of the nation's poorest regions. While providing a product vital to expansion, the company also has played an active role in attracting business and industry to the area. The companies utilities have announced numerous agreements in recent years to provide power to manufacturers, gas processing plants and other new commercial and industrial sites in the Gulf South. In the aftermath of hurricanes Katrina and Rita in 2005, Gustav and Ike in 2008, Isaac in 2012, Harvey in 2017, a record-breaking series of hurricanes in 2020 including Hurricane Laura, and a series of damaging winter storms and tornadoes, Entergy companies have played a key role in rebuilding infrastructure so that communities affected by the storms have the best chance to revitalize their economies.

In addition to economic concerns, Entergy is heavily involved in environmental and social issues. Believing that all companies should be good corporate citizens, Entergy has pledged to cap greenhouse gases by partnering with the Environmental Defense Fund. In 2001 the company was the first utility in the United States to voluntarily limit carbon emissions. And in 2021 Entergy announced it is accelerating its climate action goals with a commitment to achieving net-zero carbon emissions by 2050. In addition it is working hard on its low-income initiatives to help poor and fixed-income families with assistance when utility bills are higher during extreme cold and heat. Entergy leadership is actively involved with helping the Mississippi Delta region, one of the most economically deprived in the country, by attracting new business and interest in this untapped resource.

In 2007 Entergy sponsored an influential study on poverty often cited in the national policy debate, and announced a renewed commitment to reduce greenhouse gas emissions. During 2008, Entergy was included in the Forbes list of American's Most Trustworthy Companies, and received a special Award of Excellence from Platts Global Energy Awards for Entergy's "extraordinary track record of standout performances year after year" over the past decade. The 2009 Sustainability Yearbook recognized Entergy among the top-scoring 15 percent of 2,500 worldwide companies on corporate sustainability measurements. In 2015, the company was named to the Dow Jones Sustainability North American Index and World Index. Entergy has been included on at least one of those indexes every year since 2002. In addition, in 2015 Corporate Responsibility Magazine again named Entergy Corporation as one of the top 100 corporate citizens in the United States. In 2015 the company was named for the eighth consecutive year by Site Selection Magazine one of the "Top Utilities in Economic Development in North America." Leo P. Denault, chairman and CEO, has noted that Entergy has a "unique opportunity in our utility business to power the industrial renaissance that is occurring in the Gulf South region."

The Entergy story began with a handshake between two people and it continues with another handshake -- a handshake that is not just a greeting between two businessmen wanting to make a deal, but a grasp between a business and its stakeholders. Entergy is reaching out to all customers, stockholders, regulators, and other interested parties to help realize what Harvey Couch knew in the earliest days of the company -- that if we are to be successful we must provide a reliable product at a good price. Entergy works hard every day at making this happen.
