Dominion Energy Customers Will Benefit From Stronger Grid

Dominion Energy Virginia customers will continue to experience more reliable service, new tools to manage energy usage, and greater access to clean energy sources as efforts continue on the Company’s 10-year plan to transform the electric distribution grid.

With Phase I of the Grid Transformation Plan (GT Plan) currently underway, Dominion Energy Virginia is now focusing its efforts on the second phase of the plan to provide smarter, stronger, and greener energy solutions to customers. A new proposal filed with the State Corporation Commission (SCC) on June 21 outlines plans for Phase II, and includes approximately $669 million in capital investment for the years 2022-2023.

Phase I of the GT Plan launched activities to enhance the reliability and security of the distribution grid and to develop a new customer information platform (GIP) that enhances services to customers. Phase II layers in investments needed to facilitate and optimize the integration of distributed energy resources (DERs), such as small-scale solar, wind, and energy storage facilities, and electric vehicles. The current grid was not built to accommodate a significant amount of DERs, which can produce a bi-directional flow of energy rather than the traditional energy flow from large power stations to homes and businesses.

To effectively integrate DERs, the Company needs more in-depth data about grid conditions, as well as the systems to process, manage, and use that data to optimize grid operations. To that end, the Company proposes:

  • Continued deployment of smart metering infrastructure and intelligent grid devices that will gather and transmit data in near real-time over a secure telecommunications network.
  • New investments in technology, including installation of two systems that will manage and use this influx of data, as well as a system that will leverage the capabilities of smart grid control devices to improve customer reliability.

Many of the projects proposed for Phase II, such as smart meters and intelligent grid devices, focus on facilitating the integration of DERs, while continuing to address the reality that reliability and security are vital to the Company and its customers. Recent federal and state clean energy policies such as the Virginia Clean Economy Act of 2020 (CCEA), FERC Order 2222, and commitments and incentives to speed the transaction to electric vehicles have accelerated the need for a transformed energy grid capable of supporting significant volumes of renewables and DERs.

Virginia’s regulatory structure encourages investments to ensure the continued reliability of the electric grid, ensures fiscal oversight to provide affordable energy to customers, and facilitate the continued growth of renewables in line with both Dominions Energy’s commitment to net zero carbon and methane emissions by 2050 across the footprint, and the requirements set forth in the VCEA.

The bulk of investments to date in smart meters and the CIP fall within the review period for the Company’s ongoing rate case before the SCC. Dominion Energy’s proposed treatment of those costs ensures that customers will see no associated rate increase arising from that proceeding. In a separate upcoming filing, the Company will seek recovery of other Phase I grid transformation project costs. Phase II projects, if approved by the SCC, will be subject to cost recovery at a later date.

According to a cost-benefit analysis performed by West Monroe Partners, a business consulting firm, the investments will provide a range of customer benefits, including reliability improvements, energy and demand savings, more accurate and timelier customer information, and improved resiliency of service to critical infrastructure, among others. The analysis concluded that the proposed investments represent an overall benefit to the customers and a positive business case for the Company.

The New Local News Model

On July 1, we started a new way to pay for news. Yes, we want you to subscribe, but we know nobody subscribes to every site they visit just because there's a paywall.

So if you don't want to subscribe (even at the low price of $39.99 for a year), you can pay for access to individual articles. Or just buy a 24-hour pass, as if you were buying a single copy of a newspaper. We use a new payment service called Transact, which lets you pay for individual articles in as little as three seconds. And you will get $3 in credit when you sign up (just an email address, no credit card required), which will let you pay for at least 20 articles.

This is new for everyone, so we're going to ease you into this. Initially, there won't be many articles that you have to pay for. Short ones will always be free. And even the longer stories will let you read the first half or so for free. We'd love to hear what you think, so send us a note at feedback@peninsulachronicle.com.
