You too can join the fascinating world of electricity – a host of technologies that captured the imagination of Thomas Edison and thousands of engineers since. We are proud to be home to engineers and technicians who are on the forefront of our industry’s high-voltage systems. Every aspect of our work – designing, building and maintaining systems — touches new technology.
Planners work with sophisticated modeling systems to project electric load growth and anticipate new system requirements to meet constantly changing residential, industrial and business needs, as well as regional power generation conditions in one of the fastest growing states. Literally millions of homes and businesses rely on this planning to prevent widespread outage problems. We work with other utilities in Georgia and neighboring states to jointly plan and operate the entire regional power grid.
Planning for new substation and power line construction is supported by teams of experts in mapping and geospatial systems. In fact, Georgia Transmission recently teamed with the Electric Power Research Institute (EPRI) to develop a new GIS-based computer modeling system and new procedures for systematically evaluating potential geographic locations for electric transmission lines. This industry-leading model has been adopted by other utilities and could change the way many utilities evaluate and determine new high-voltage power lines sites.
Our new construction and equipment upgrades involve the latest in high-voltage transformers, capacitors, regulators and other substation equipment. Our employees, for instance, recently worked with a leading manufacturer in Japan on the design of a new voltage amperes reactive (VAR) compensator which helps keep voltage stable over long-distances — a first for Georgia’s bulk transmission system.
In addition, we employ the latest power line component technology, such as experimentation with low-sag, high-capacity cables. We have national-level expertise with underground high-voltage systems, and overhead power line construction. Our company recently created an improved 500-kilovolt power line tower design, and we use the latest substation and power line design and construction techniques. This work can involve conceptual photography, 360-degree view shed modeling, and detailed analysis of components.
What is built must be inspected and maintained. Our operations and maintenance departments have worked together to field install and maintain new digital fault recorders/sequence of events and relay data servers. We’re using dissolved gas analysis, the diagnosis of gas from transformers for early detecting of operational abnormalities. We are working with the latest daylight infrared cameras to improve damage assessments during aerial and ground inspections of transmission lines and substations. We are experimenting with satellite communications as well as correlating lightning strikes with transmission line faults.
Our electronics maintenance department manages a wide range of electronic communications (satellite, frame relay, spread spectrum and wireless cellular) and metering equipment, as well as hardened substation computers that allow for remote maintenance and repair at the company’s nearly 650 substations and 3,000-mile network of transmission lines. Since systems problems can affect electricity for thousands of people, we are front-line emergency personnel for recovery from major storms and natural disasters and rapid repairs. Our operations are so advanced that our electronic maintenance department has created an in-house research and development laboratory that simulates our statewide electric system and enables engineers and technicians to troubleshoot real-world problems and test emerging technologies prior to field implementation.
With us, you can help us stay on the forefront of technology as our industry sees changes in energy conservation, renewable generation, distributed generation and other areas.
