Demand for electricity is up in the United States, and so is its price. One way to increase supply and lower costs is to build new power plants, but that can take years and cost a fortune. Talgat Kopzhanov is working on a faster, more affordable solution: the generator replacement interconnection process.
The technique links renewable energy sources to the grid connections of shuttered or underutilized power facilities and coal plants. The process uses the existing interconnection rights and infrastructure when generating electricity, eliminating the years-long approval process for constructing new U.S. power facilities.

Kopzhanov, an IEEE senior member, is an asset manager for Middle River Power, based in Chicago. The private equity–sponsored investment and asset management organization specializes in U.S. power generation assets. “Every power plant has its own interconnection rights,” he says, “but, amazingly, most are not fully utilizing them.” Interconnection rights give a new power source—such as solar energy—permission to connect to a high-voltage transmission system. “We build the new renewable energy resources on top of them,” Kopzhanov says. “It’s like colocating a new power plant.” He recently oversaw the installation of two generator-replacement interconnection projects, one for a solar system in Minnesota and the other for a battery storage facility in California. A fast-track approach that cuts costs Artificial intelligence data centers are driving up demand and raising electricity bills globally. Although tech companies and investors are willing to spend trillions of U.S. dollars constructing new power facilities, it can take up to seven years just to secure the grid interconnection rights needed to start building a plant, Kopzhanov says. The lengthy process involves system planning, permit requests, and regulatory approvals. Only about 5 percent of new projects are approved each year, he says, in part because of grid reliability issues. The interconnection technique takes about half the time, he says, bringing cleaner energy online faster. By overcoming interconnection bottlenecks, such as major transmission upgrades that delay renewable projects, the process speeds up project timelines and lowers expenses.
Power Engineers Are in Short Supply If you want to work in a secure, recession-proof industry, consider a career in power engineering, Kopzhanov says—especially in an unstable job market, when even Amazon, Microsoft, and other large companies are laying off thousands of engineers. The power industry desperately needs engineers. The global power sector will require between 450,000 and 1.5 million more engineers by 2030 to build, implement, and operate energy infrastructure, according to an IEEE Spectrum article based on a study conducted this year of the power engineering workforce by the IEEE Power & Energy Society. One of the reasons for the shortage, Kopzhanov says, is that the power sector doesn’t seem exciting to young engineers. “It has not been popular because the technologies we’re implementing nowadays were invented quite a long time ago,” he says. “So there were not too many recent innovations.” But with new technologies being introduced, such as the generator replacement interconnection process, now is a great time to get into the industry, he says. “We are facing lots of different kinds of interesting and big challenges, and we definitely need power engineers who can solve them, such as the supply and demand situation facing us,” he says. “We need right-minded people who can deal with that. “Until this point, the marvelous engineering systems that have been designed and built with close to 100-percent reliability are not going to be the case moving forward, so we have to come up with innovative approaches.” Just because you have a power engineering degree, however, doesn’t mean you have to work as a power engineer, he says. “Most students might assume they will have to dedicate themselves to only being a power engineer for the rest of their life—which is not the case,” he says. “You can be on the business side or be an asset manager like me. “The power sector is an extremely dynamic and vast area. You’ll have many paths to pursue along your career journey.”
Kopzhanov explains the technique in an on-demand educational webinar, Unlocking Surplus Interconnection Service. Colocating Renewable and Thermal Power Plants, hosted by the IEEE Power & Energy Society. The webinar is available to the public for a fee.
Kopzhanov has been involved with several recent generator replacement interconnection installations. In May the Sherco Solar project in Sherburne County, Minn., replaced a retiring coal plant with approximately 720 megawatts of solar-powered generators, making it the largest solar-generating facility in the region. The first 460 MW of capacity is expected to be operational soon.
Another new project, developed with Middle River, is a battery system installed in April at California’s Hanford Hybrid Energy Center, a natural gas reliability facility. It used existing and incremental interconnection capacity to add the storage system. The surplus renewable energy from the batteries will be used during peak times to reduce the plant’s greenhouse gas emissions, according to a Silicon Valley Clean Energy article about the installation.
“These projects are uniquely positioned to be colocated with existing power plants,” Kopzhanov says. “But, at the same time, they are renewable and sustainable sources of power—which is also helping to decarbonize the environment and meet the emission-reduction goals of the state.”
