DTE Energy's history
DTE Energy, formerly known as Detroit Edison until 1996, is a Detroit-based diversified energy company with a long history of serving Michigan with both electric and gas services. Its earliest direct corporate ancestor, the Edison Illuminating Company of Detroit, was founded in 1886 and began serving its first customers. By the turn of the century, the Edison Illuminating Co. and the Peninsular Electric Light Co. provided all commercial electric lighting and power in Detroit.
In January 1903, Detroit Edison purchased securities of the two companies and incorporated. That same year, construction began on the Delray 1 power plant, and Henry Ford, who had left Edison Illuminating four years earlier, founded Ford Motor Co. In 1903, the Detroit Gas Co. was renamed the Detroit City Gas Co. It secured franchises for Highland Park and Hamtramck and increased its customer base to more than 67,000. In 1904, Detroit Edison signed its first power contract with an automobile company, the Cadillac Motor Car Co.
In 1905, a majority of the Detroit City Gas Co. was acquired by the American Light & Traction Co., a holding company that controlled utility and transportation interests. With the added demand for electricity, the Delray 2 power plant was added in 1908. In 1913, Detroit City Gas acquired additional service territory that included the communities of River Rouge, Wyandotte, Dearborn, Ecorse and Trenton.
Between 1924 and 1929, Detroit Edison increased its production capacity by constructing the Marysville, Trenton Channel, and Delray 3 power plants. In 1937, a plan was developed to merge Detroit City Gas Co. with three other gas companies, creating the Michigan Consolidated Gas Co. (MichCon) in 1938. In 1956, Detroit Edison broke ground for the Enrico Fermi Power Plant and also began work on the River Rouge Power Plant.
In January 1996, Detroit Edison established a holding company and changed its name to DTE Energy. On May 31, 2001, DTE Energy merged with MCN Energy Group to become Michigan's largest energy company. In 2007, DTE Energy began acquiring wind development rights, and by 2012, the company had constructed its first wind parks. In 2013, DTE Energy adopted "DTE" as its customer-facing brand, and Detroit Edison Company became DTE Electric Company.
DTE Energy currently operates one nuclear plant, the Enrico Fermi Nuclear Generating Station, and has invested billions in renewable energy assets. The company has expanded its business lines to include Industrial Energy Services, Renewable Energy, and Environmental Controls. DTE Energy's electric utility serves 2.2 million customers, and its natural gas utility serves 1.3 million customers in Michigan.

Between 1924 and 1929, Detroit Edison increased its production capacity by constructing the Marysville, Trenton Channel, and Delray 3 power plants.
In 1937, a plan was developed to merge the Detroit City Gas Co., the Grand Rapids Gas Light Co., the Washtenaw Gas Co., and the Ann Arbor Gas Co. The merger was approved in 1938, resulting in the formation of the Michigan Consolidated Gas Company, or MichCon. In 1945, to meet the increasing demand for natural gas, the Michigan-Wisconsin Pipeline was completed.
In 1954, Detroit Edison added the St. Clair Power Plant, one of the largest power plants globally at the time. The company continued to expand its operations, breaking ground for the Enrico Fermi Power Plant and the River Rouge Power Plant in 1956. This was followed by another construction phase, including the Fermi 2 nuclear plant and the Monroe Power Plant Units 1-4, which came online from 1971 to 1974.
In 1983, Detroit Edison created Utility Technical Services, later renamed SYNDECO, to sell its engineering expertise. In 1986, the Detroit Edison Foundation was established to oversee the company's charitable initiatives.
In January 1996, Detroit Edison reorganised as a holding company, DTE Energy. The name "DTE" was chosen as it was the existing stock symbol for Detroit Edison, while "Energy" reflected the company's vision to provide integrated energy solutions.
DTE Energy has continued to evolve, acquiring wind development rights and constructing wind parks. It has also faced challenges, including allegations of discrimination against black employees, for which Edison agreed to pay $4.25 million in damages.
Today, DTE Energy is a diversified energy company, serving millions of customers in Michigan and beyond.

The impact of storms
DTE Energy, formerly known as Detroit Edison, is the company that owns Detroit's electric grid. It is a Detroit-based diversified energy company with a long history of serving Michigan with both electric and gas services, dating back more than 150 years.
Detroit's electric grid has been vulnerable to powerful storms, and the impact of these storms has been felt by tens of thousands of residents. Thunderstorms and other powerful storms have knocked out electricity for extended periods, causing significant inconvenience and financial losses for residents.
One key factor contributing to the vulnerability of Detroit's grid is the issue of tree trimming. Michigan has a wealth of trees, and industry experts have criticized DTE Energy for inadequate tree trimming around power lines. The company's trimming cycle has been longer than the industry standard, and it has only trimmed branches within a few feet of the lines instead of addressing all branches that threatened its wires. As a result, equipment has been left exposed to a high number of branches and trees, increasing the likelihood of outages during storms.
Additionally, DTE Energy's approach to upgrading old equipment has been characterized as purely reactive. Instead of proactively replacing aging infrastructure, the company has tended to fix things only when they break. This has led to more frequent breakages as equipment ages, and patched wires from previous storms have been left weakened and more vulnerable to lightning.
Furthermore, a 1974 state law requiring new distribution infrastructure to be built underground has created a disparity in how older and newer regions of DTE's system fare during storms. The older parts of the grid with overhead distribution lines are more susceptible to outages when storms occur.
The combination of these factors has left Detroit's electric grid vulnerable to strong storms, resulting in frequent and prolonged outages that impact the lives and livelihoods of the city's residents.

Aging equipment
DTE Energy (formerly Detroit Edison until 1996) is a Detroit-based diversified energy company that serves 2.2 million customers in Michigan. The company has been criticized for its failure to replace aging equipment, which has left the grid vulnerable to storms and resulted in frequent outages.
Over the years, DTE has taken a "purely reactive" approach to equipment replacement, choosing to fix things only when they break. This has led to a higher frequency of breakages as the equipment ages, with some equipment well beyond its expected lifespan. For example, poles have become brittle and are more susceptible to breaking under windy conditions. Wires that were previously damaged during storms were patched up instead of replaced, leaving them weakened and more vulnerable to lightning strikes due to worn-out insulation.
The fuse cutouts and reclosers, which are similar to circuit breakers, are also susceptible to failure due to overcurrents. Additionally, DTE's service territory faces issues with old pole tops or crossbars, which hold insulators that separate the wires from the wood.
DTE's neglect of infrastructure upgrades and inadequate tree trimming has contributed to the grid's vulnerability. The Public Services Commission did not seriously challenge DTE on these issues until around 2010 when outages became more frequent. Experts believe that it will take significant time and effort for DTE to improve the reliability of its grid.
To address these issues, DTE has developed a four-point plan to improve the electric grid. This plan includes adding technology and smart devices, modernizing existing infrastructure, rebuilding significant portions of the grid, and trimming trees. The company is also investing in cleaner sources of energy, such as converting power plants to run on natural gas instead of coal and developing more wind and solar energy sources.

The role of regulators
DTE Energy, formerly known as Detroit Edison, is the largest electric utility in Michigan and one of the largest in the United States. It has a long history of serving Michigan with electric and gas services, dating back more than 150 years.
In more recent times, the regulatory landscape has become more active in overseeing and influencing the operations of DTE Energy. Notably, the Public Services Commission has been involved in addressing the issues related to ageing equipment and infrastructure upgrades. However, according to Jester, an expert in the field, the commission did not seriously challenge DTE on its ageing equipment until around 2010, and only started pushing for significant infrastructure upgrades around 2014.
Federal regulators also played a role in the merger that contributed to the formation of DTE Energy. In 1937, a plan was developed to merge several gas companies, including the Detroit City Gas Co., resulting in the creation of the Michigan Consolidated Gas Co. (MichCon) in 1938. This merger was approved by state and federal regulators, including the Michigan Public Service Commission and the Securities and Exchange Commission.
Additionally, DTE Energy's operations are subject to federal regulations and policies. For example, in April 1996, the Federal Energy Regulatory Commission issued a new set of rules impacting transmission capacity, wholesale and retail competition, and other issues in the energy sector.
Overall, the role of regulators in Detroit's electric grid has been a combination of oversight, approval of mergers, and the implementation of policies and standards that influence the operations and infrastructure decisions of DTE Energy.
