Economic Indicators

EU6

Approach to ensure short and long-term electricity availability and reliability

We address availability and reliability in our Integrated Resource Plans that are submitted to state regulatory agencies. Please see this sample Integrated Resource Plan.

There is also extensive discussion on various pages of our Form 10-K filed with the Securities and Exchange Commission.

EU7

Demand-side management programs

Demand-side management programs are specific to each state and are contingent on approvals from state utility commissions. The programs available in each state are described on the Duke Energy web site. They are also discussed in general in our Form 10-K filed with the Securities and Exchange Commission. (Enter energy efficiency in the search box.)

EU8

Research and development activity

Our technology development group focuses on emerging technologies that have the potential to create opportunities for Duke Energy and impact Duke Energy's business. They also coordinate much of our research and development through programs administered by the Electric Power Research Institute, the U.S. Department of Energy and other organizations.

Also, please see page 5 of Duke Energy's 2020 Climate Report.

EU9

Provisions to decommission nuclear power sites

See our Form 10-K filed with the Securities and Exchange Commission. A search on decommissioning will yield numerous results.

G4-EC1

Financial performance

See our Sustainability Report and our Annual Report and Form 10-K for detailed information.

G4-EC2

Financial implications of climate change

See Advancing Low-Carbon Technologies and our responses to the Carbon Disclosure Project. Also see our Form 10-K filed with the Securities and Exchange Commission (search on carbon for multiple references).

See Duke Energy's 2020 Climate Report, where costs and other financial implications of climate change are discussed throughout the report.

G4-EC3

Defined employee benefit plan obligations

See our Form 10-K filed with the Securities and Exchange Commission (search on defined benefit for multiple references).

G4-EC4

Financial assistance from government

We do not centrally track the annual accrual of tax credits, subsidies and other incentives from our many governmental entities.

G4-EC5

Entry level wages

Duke Energy's lowest entry level wage is $14.50 per hour for U.S. employees. The Federal minimum wage is $7.25 per hour. Minimum wage for federal contractors is $10.60 per hour.

G4-EC6

Procedure for local hiring, & percent of local senior management

Hiring and promotion is based on merit, not whether the candidate is from a particular locality.

G4-EC7

Development and impact of infrastructure investments and services supported

We help strengthen our communities through economic development initiatives and financial support. See the Customers section of our Sustainability Report, where we describe how Duke Energy improves the lives of our customers and vitality of our communities.

G4-EC8

Indirect economic impacts

See Economic Development in our Sustainability Report, and G4-EC7.

G4-EC9

Percent of local spending for supplies

Duke Energy buys more than $13.5 billion of goods and services each year; of that about $4 billion is spent with local suppliers.

See Supporting Suppliers Who Share Our Values in our Sustainability Report.

EU10

Planned capacity and projected demand

We address planned capacity and projected demand in our Integrated Resource Plans that are submitted to state regulatory agencies. Please see this sample Integrated Resource Plan.

EU11

Average thermal plant efficiency

2019 fleet efficiencies were as follows:

• Coal-fired Generation Plants: 9,320 BTU/kwh;

• Open-Cycle and Combined-Cycle Natural Gas-fired Plants: 7,344 BTU/kwh

EU12

Transmission and distribution losses

Our transmission and distribution losses are consistent with averages reported by other utilities, but the methodology for calculating these losses is inconsistent across the industry. Because of this inconsistency, the Electric Power Research Institute (EPRI) as part of Program 172 (Efficient Transmission and Distribution Systems for a Low Carbon Future) has released a Distribution System Losses Calculation Tool. We use the new EPRI methodology and a variety of other tools to conduct loss surveys on portions of our system on a periodic basis. Transmission losses are approximately 1.8 percent, and distribution losses are approximately 2.5 percent.
