The POWER Interview: Protection Testing Paradigm—How Utilities can Adapt to the Digital Era

February 6, 2022

The digital transformation in the power generation industry touches several areas, encompassing engineering, monitoring and control, asset performance, and operations optimization, among others. Power plant operators know the digital era has been a perfect fit for their industry, enabling digitization to reduce risk, save costs, optimize performance, and speed crisis response.

Doble Engineering is a company at the forefront of the digital age in power generation, enabling utilities and power plant operators to understand asset health through the group’s diagnostic test equipment, software, and services for the electric power industry.

Ed Khan, director of Protection Training at Doble Engineering, provided POWER with insight into the ways digitization has changed the power industry. Khan and Doble continue to research and develop ways digital-based applications can serve electricity producers moving forward, at a time of rapid change in the power sector, particularly when it comes to protecting assets and operations.

Georgia Power Plans to Retire All Coal Units by 2035

Georgia Power plans to shutter most of its coal fleet by 2028 and completely exit coal-fired power by 2035, according to the utility’s latest integrated resource plan (IRP) filed with state regulators on Jan. 31.

The Southern Co. subsidiary on Monday said it would make more investments in natural gas-fired generation, along with renewable energy, to make up for the lost coal-fired electricity output. The utility also plans to have two new reactors online at its Plant Vogtle nuclear power site, one by the end of this year and the other by mid-2023, that will add more than 2 GW of generation capacity to the company’s fleet.

Georgia Power CEO Chris Womack on Monday said environmental concerns and the current economic landscape of power generation factored into the company’s decisions. The utility files a new IRP with the Georgia Public Service Commission (PSC) every three years. Its previous IRP was approved in July 2019. Hearings will be held over the next few months to discuss the utility’s plan, with a vote by the PSC expected this summer.…

How Power Plants Can Reduce Asset Integrity Risks with Digital Technology

There are countless risks associated with power plant operations. For example, the risk of equipment failure is present in virtually every power plant system. In some cases, the risk is very low and could even be inconsequential. In others, it’s much higher and could be catastrophic, not only to plant operation, but also to the health and safety of workers. Understanding where the greatest risks lie and acting to reduce the likelihood of an unwanted incident should be high on every plant manager’s to-do list.

Digital technology has made the task of managing risk much easier. Tools are available today that can organize data and help users evaluate where the most probable and/or consequential failures are likely to occur. For example, risk-based asset integrity management (AIM) software, which often uses data imported from a plant historian or other legacy software systems, can sort and prioritize data to identify areas of concern and provide insight for decision-makers.

There are several companies that offer AIM products.…

A Win-Win-Win Solution for DER Owners, the Power Grid, and the Environment

New distributed energy resources (DERs) are being added to the power grid every day. However, DERs don’t automatically provide owners with the greatest value possible. In many cases, that requires the help of an aggregator, that is, a company that specializes in managing DERs owned by a pool of clients and optimizing performance of the overall system based on real-time signals coming from the wholesale power markets.

“Wholesale electricity markets need grid services from distributed energy resources. We connect those underutilized distributed energy resources—typically behind customer meters—to those wholesale power markets to orchestrate and monetize those resources to deliver reliable, cost-effective, and clean energy,” Gregg Dixon, co-founder and CEO of Voltus, said as a guest on The POWER Podcast.

Voltus’ customers and grid services partners generate cash by allowing Voltus to maximize the market value of their flexible load, distributed generation, energy storage, energy efficiency, and electric vehicle resources. “Voltus is to the electricity industry what Airbnb is to the real estate market in the sense that Airbnb connects under-utilized apartments or homes to buyers who want to make use of those under-utilized assets, and Voltus does that for the electricity grid,” Dixon explained.…

Evergy to Build Solar Array at Kansas City Coal Power Plant Site

Evergy, a Kansas City, Missouri–headquartered energy provider serving about 1.6 million customers in Kansas and Missouri, announced plans on Jan. 5 to build a 10-MW solar array at the company’s Hawthorn power plant.

“Our Hawthorn power plant is a prime location to showcase Kansas City’s commitment to renewable energy and our city’s forward-thinking progress,” said Chuck Caisley, Evergy senior vice president and chief customer officer. “Bringing this renewable energy to Hawthorn will limit the expense by using infrastructure already in place.”

The Hawthorn Generating Station is located in northeast Kansas City, Missouri, and includes a 564-MW coal-fired unit known as Unit 5 and a 225-MW natural gas-fired combined cycle unit known as Unit 6&9. Hawthorn 5 was built in 1969, but after an explosion in February 1999 destroyed the power plant boiler, the unit was substantially rebuilt and returned to service in 2001.

Evergy plans to build the solar array on 67 acres to the northwest of the plant. The site is expected to include more than 22,000 solar panels and be operational in fall 2022.…
