transmission lines technical

"Transmission lines carry electricity from generation plants to local..."

High-voltage towers and cables that carry electricity from power plants to cities and substations, like highways that move energy rather than cars. For investors, transmission lines are long-lived, capital-intensive assets whose condition, capacity and regulatory treatment affect utility revenues, reliability and the ability to connect new generation; bottlenecks or upgrades can change costs, permit timelines and future returns.

high-voltage transmission lines technical

"These upgrades include the installation of advanced high-voltage transmission lines..."

High-voltage transmission lines are the long-distance power “highways” that carry large amounts of electricity between generators and distribution networks using elevated voltages to move energy efficiently over many miles. Investors care because these lines are critical infrastructure: their capacity, reliability, construction costs, regulatory approvals, and vulnerability to outages or upgrades directly affect utility revenues, grid resilience, project economics, and the pace of energy transition investments.

substations technical

"These upgrades include the installation of advanced high-voltage transmission lines, updated and improved substations..."

Substations are fenced facilities on the power grid where electricity is transformed, routed and controlled—think of them as traffic interchanges for electrical flow, using transformers and switches to change voltage and direct power between high-voltage long-distance lines and local distribution networks. They matter to investors because their condition, capacity and modernization affect utility reliability, maintenance costs, regulatory compliance and future growth; failures or upgrades can directly influence earnings, capital spending and the value of energy assets.

smart grid technologies technical

"updated and improved substations, and smart grid technologies."

Smart grid technologies are digital sensors, communications, software and controls added to the electricity system to monitor and manage generation, delivery and consumption in real time. They matter to investors because they can lower operating costs, reduce outages, enable new services (like charging for electric vehicles or selling stored power), and create predictable revenue streams—think of upgrading a neighborhood’s electrical network the way a smartphone upgrades a basic phone, unlocking new capabilities and value.

battery energy storage systems technical

"Plant Wansley near Roopville, where Georgia Power plans to build new battery energy storage systems..."

Large, grid-connected rechargeable battery systems that store electricity for later use, like a giant household battery for cities or power plants. They matter to investors because they help balance supply and demand, enable more renewable energy, reduce outage risk, and create revenue through services such as selling stored power at peak times or participating in grid stability programs, while requiring upfront capital and having performance limits tied to lifespan and degradation.

natural gas generation technical

"plans to build new battery energy storage systems and natural gas generation."

Electricity produced by burning natural gas in power plants or by using gas-driven turbines; think of it like a home stove or car engine scaled up to run generators that feed the electric grid. Investors watch it because it links power company profits and utility bills to natural gas prices, plant operating costs, and environmental rules—so shifts in fuel cost, demand for electricity, or emissions policy can directly affect revenues and valuations.

integrated resource plan (irp) regulatory

"the Georgia Public Service Commission (PSC) approved the 2025 Integrated Resource Plan (IRP)..."

An integrated resource plan (IRP) is a long-range strategy used by utilities and regulators to decide how to meet future electricity demand through a mix of power plants, grid upgrades, energy purchases, efficiency programs and demand-reduction measures. It matters to investors because the IRP sets expected capital spending, operating costs, and regulatory approvals that shape a utility’s future revenue, risk profile and rate changes — like a household budget that plans major purchases and monthly bills years ahead.

Investments reflect Georgia Power's ongoing commitment to being here for customers and the state—serving the energy needs of a growing Georgia, while enhancing service and reliability for local communities

ATLANTA, Dec. 8, 2025 /PRNewswire/ -- Georgia Power continues to invest in communities across the state by upgrading and enhancing the power grid to improve reliability and resiliency, and meet new demand in the coming years. The company recently announced major transmission infrastructure projects in Coweta, Fayette, Fulton and Heard counties—advancing energy reliability and supporting Georgia's continued growth. Transmission lines carry electricity from generation plants to local distribution networks. These upgrades include the installation of advanced high-voltage transmission lines, updated and improved substations, and smart grid technologies. Together, these improvements will help ensure customers continue to receive safe, reliable energy for decades to come.

"As Georgia has grown, we've been here every step of the way—supporting new businesses and families with the energy they need," said Melvin Roland, senior vice president of Transmission at Georgia Power. "These new transmission lines and infrastructure upgrades will help strengthen the grid, reduce outages, and build a more resilient energy future for our communities. Additionally, the new transmission lines will optimize electricity flow across the grid, improving efficiency and reliability for customers in South Metro Atlanta."

Georgia Power has made significant investments in the power grid across South Metro Atlanta in recent years, including the Ashley Park 500/230 kV substation and 230 kV lines from Ashley Park, which stretch more than 10 miles through Fayette County and are expected to be completed in spring 2026. Now, the company is moving forward with the Ashley Park – Wansley 500 kV line, one of the first new projects under the company's latest 10-year transmission plan. The 35-mile transmission line will connect the Ashley Park Substation north of Fayetteville to Plant Wansley near Roopville, where Georgia Power plans to build new battery energy storage systems and natural gas generation. Survey work has started on the project, with clearing and grading beginning in the first quarter of 2027, followed by construction in the third quarter of 2027, and completion expected in the second quarter of 2028.

Additional information about the Ashley Park – Wansley 500 kV line is available on a dedicated project website here.

Georgia Power's transmission project process is designed to be flexible, transparent and community focused in any community where significant work or enhancements to the power grid are planned. Each project is carefully planned to maximize reliability while minimizing impact on residents and the company regularly hosts community meetings and provides additional updates and information through handouts, maps, letters, and postcards to landowners and nearby businesses.

"We understand that customers may have concerns about infrastructure near their homes, and we're committed to listening and responding with care," added Roland. "Our goal is to minimize disruption and be a trusted partner throughout every phase of these critical projects."

Georgia Power's 10-year Transmission Plan

On July 15, 2025, the Georgia Public Service Commission (PSC) approved the 2025 Integrated Resource Plan (IRP), which outlines the company's strategy to meet customer energy needs and support Georgia's extraordinary growth. The plan includes a 10-year transmission roadmap featuring more than 1,000 miles of new transmission lines. These improvements will enhance system efficiency, strengthen resiliency, and ensure Georgia's energy infrastructure keeps pace with demand.
