Exhibit 99.1

North Carolina energy legislation

On October 13, 2021, Governor Cooper signed legislation into law after passage with bi-partisan approval in the North Carolina Senate by a 42-7 margin and the House of Representatives by a 90-20 margin. The legislation establishes a framework overseen by the North Carolina Utilities Commission (“Commission”) to advance state CO2 emission reductions through the use of least cost planning while providing for continued reliability and affordable rates for customers served by such generation. It also authorizes the use of performance-based regulation in North Carolina. The legislation includes several main provisions, including:

· Directs the Commission to take all reasonable steps to achieve a 70% reduction in CO2 emissions from public utilities’ electric generating facilities in the state by 2030 from 2005 levels and achieve carbon neutrality by 2050;

· Authorizes the use of performance-based regulation of electric public utilities; and

· Authorizes securitization of a portion of the North Carolina allocated costs associated with early retirement of subcritical coal-fired electric generating facilities.

The legislation modifies the bill that passed in the North Carolina House of Representatives on July 14, 2021. Key modifications include:

· Increases the 2030 CO2 emissions reduction target to 70% from 61%.

· Gives the Commission discretion to achieve the carbon reduction goals, while still conforming to least cost planning principles and provides for continued reliability.

o Removes prescribed resource additions and plant retirement dates.

· Allows for securitization of 50% of the remaining North Carolina allocated net book value associated with early retirement of subcritical coal-fired electric generating facilities, a change from $500 million.

Carbon Reduction Plan

· By December 31, 2022, the Commission shall develop an initial Carbon Plan to achieve a reduction of 70% CO2 emissions by 2030 and carbon neutrality by 2050, considering all resource options and the latest technological advancements. Carbon Plan provisions include:

o The Carbon Plan will be reviewed every two years and may be adjusted as necessary;

o Commission discretion to determine timing and resource mix to achieve both least cost compliance and CO2 reduction goals; and

o Preservation or improvement of grid adequacy and reliability as generation and resources change.

· All new generation facilities or other resources selected by the Commission in order to achieve the authorized carbon reduction goals shall be owned and recovered on a cost of service basis by Duke Energy, with the exception of solar generation facilities. In the case of solar generation facilities, 55% shall be owned and recovered on a cost of service basis by Duke Energy and 45% shall be procured through long term purchase power agreements with third parties.

Regulatory Reform

· As North Carolina makes the transition to cleaner forms of generation, the legislation introduces modernized recovery mechanisms that promote more efficient recovery of investments and align incentives between the Company and the state’s energy policy objectives.

· The legislation authorizes the Commission to consider approval of Performance-Based Regulation that would include the following components:

o Multi-year rate plans with a maximum 3-year term, with increases in years 2 and 3 for projected capital spend capped at 4% of year 1 baseline revenues.

§ Under the multi-year rate plan, any earnings exceeding 50 basis points above the authorized ROE will be directly refunded to customers.

o Performance Incentive Mechanisms to track utility performance, with both incentives and penalties in aggregate capped at 1% of the utility’s revenue.

o Revenue Decoupling for Residential customer class, separating the revenue by customer from their level of consumption.

· The Performance-Based Regulation provides for prudent long-term planning and grid investments to keep electricity affordable and reliable through comprehensive Commission oversight.

Other Provisions

· The Commission shall establish rules to securitize costs associated with early retirement of subcritical coal-fired electric generating facilities to achieve authorized carbon reduction goals of 50% of remaining net book value, with the remaining net book value recovered through traditional recovery mechanisms.

· Provides for a North Carolina on-utility bill repayment program designed to make energy efficiency improvements more affordable for customers, particularly those with low to moderate incomes.

· The Department of Environmental Quality shall develop and submit a plan to the General Assembly for legislative action no later than March 1, 2022 to ensure adequate financing for the decommissioning of utility-scale solar projects.

· Establish rules for updating rates and terms of certain existing solar power purchase agreements executed under PURPA.
