Study: Extreme Event Generator Outages in Texas

LCG May 6, 2021--February’s extreme weather left millions of Texans without power after pushing an unprecedented 45 GW of generation off the system. At least 111 people died, some as a direct result of heating and power failure. The disaster captured the nation’s attention and lead the Texas legislature to pursue changes to electricity pricing and how the ERCOT Board members are chosen, as well as create new emergency rules and oversight.

Ameren Announces Net-Zero Carbon Emissions Target by 2050

LCG, September 30, 2020--Ameren Corporation announced Monday that it has established a net-zero carbon emissions goal by 2050 across all its operations in Missouri and Illinois. Milestones within the net-zero by 2050 commitment include reducing carbon emissions 50 percent by 2030 and 85 percent by 2040, based on 2005 levels. The new goals accelerate and expand on Ameren's 2017 pledge and are consistent with the objectives of the Paris Agreement and limiting global temperature rise to 1.5 degrees Celsius.The company also announced its largest-ever expansion of clean solar and wind generation while maintaining the reliability and affordability that customers have come to expect.

Ameren Corporation's chairman, president and chief executive officer stated, "Our transformative plan accelerates Ameren's transition toward cleaner energy and targets net-zero carbon emissions by 2050, while meeting our customers' expectations for safe, reliable and affordable energy."

The clean energy expansion is included in the Integrated Resource Plan (IRP) of Ameren Missouri. The IRP is a triennial filing with the Missouri Public Service Commission (PSC) that sets forth Ameren Missouri's preferred plan to transform its electricity generation portfolio over the coming decades.

To reduce carbon emissions and respond to market economics, Ameren plans to accelerate the retirement of two of its coal-fired energy centers. The Sioux Energy Center is now planned to retire in 2028 and the Rush Island Energy Center's retirement is planned for 2039. More than 75% of the company's current coal-fired energy generating capacity is expected to retire by 2040, and all coal-fired energy centers are scheduled to retire by 2042. Planned retirements begin in 2022 with the Meramec Energy Center.

To offset the retirement of coal-fired, electric generating capacity, Ameren Missouri's IRP includes significant investment of nearly $8 billion in renewable energy resources through 2040. By 2030, the company plans to add 3,100 MW of renewable generation reflecting a combined investment of approximately $4.5 billion. Renewable energy would increase to a total of 5,400 MW by 2040. In the next few months, the company plans to acquire two Missouri-based wind energy facilities for approximately $1.2 billion.

Ameren Missouri's chairman and president stated, "This is a step change in renewable energy investments and carbon emission reductions from the plan we presented three years ago. Under our plan, customers will receive significant benefits from advances in technology and falling renewable energy costs, as well as from robust energy efficiency programs to help keep their energy costs affordable."

Ameren Missouri expects to seek an extension of the operating license for the zero-emission Callaway Energy Center beyond 2044. The 1,190-MW nuclear power plant began commercial operations in 1984. Ameren sees the continued efficient operation of these carbon-free energy centers as critical to meeting corporate goals, including reaching net-zero emissions by 2050.

Ameren Corporation's chairman, president and chief executive officer stated, "We have developed a comprehensive plan that will significantly reduce carbon emissions in a responsible fashion and deliver strong customer benefits. We have also established a bold goal to achieve net-zero carbon emissions by 2050. Achieving our goal will be driven by further advancements in innovative, carbon-free technologies and constructive federal and state energy and economic policies. Working together with key stakeholders, we believe we can achieve this important goal for our customers, our communities and our country."
