Key Terms

electric grid, megawatts, energy storage

3 terms

electric grid technical

"This is due to extremely cold temperatures that are driving unusually high demand for electricity across the southeast. It is meant to help protect the grid and keep electricity flowing..."

The electric grid is the large, interconnected system of power plants, wires, substations and control centers that generate electricity and deliver it to homes, factories and businesses. Investors care because the grid’s capacity, reliability and cost influence energy companies’ revenues, utility bills, and the ability of industries to operate; think of it like a highway network whose condition and congestion directly affect delivery speed, costs and economic activity.

megawatts technical

"Duke Energy Florida, a subsidiary of Duke Energy, owns 12,300 megawatts of energy capacity..."

A megawatt is a measure of electrical power equal to one million watts, describing how much electricity a plant or device can generate or use at a single moment. Investors use megawatts to compare the size and earning potential of energy projects—larger capacity usually means more electricity to sell—much like comparing the horsepower of engines to judge how much work they can do. Knowing megawatts helps assess scale, revenue potential, and grid impact of energy assets.

energy storage technical

"The company is investing in major electric grid upgrades and cleaner generation, including natural gas, nuclear, renewables and energy storage."

Energy storage involves capturing and holding excess energy produced during periods of low demand for later use when demand is higher. Think of it like a rechargeable battery that saves power for when it’s needed most. For investors, energy storage is important because it helps balance supply and demand, making energy systems more reliable and efficient, which can influence the value of energy-related assets and technologies.

ST. PETERSBURG, Fla., Feb. 1, 2026 /PRNewswire/ -- As Florida continues to experience the coldest air in the state since 2018, Duke Energy is asking all customers to voluntarily reduce their energy use from 5 to 9 a.m. EST on Monday, Feb. 2, 2026.

Below are ways customers can lower their energy use:

• Turn off any unnecessary devices, unused plug-ins and lights.
