New commitments for Virginia

Since we announced the combination between NextEra Energy and Dominion Energy in May, we've been listening to stakeholder feedback. As a result, the companies recently announced an enhanced package of commitments for Virginia that would expand customer benefits, create jobs and support long-term economic growth.

WHAT IT MEANS

Article on employee intranet:

The big picture: Since we announced the combination between NextEra Energy and Dominion Energy in May, we've been listening to stakeholder feedback. As a result, the companies recently announced an enhanced package of commitments for Virginia that would expand customer benefits, create jobs and support long-term economic growth.

Why it matters: These enhanced commitments demonstrate how the proposed combination would benefit Virginia and Virginians through customer affordability, job growth, workforce development and long-term investment in local communities.

What's new

·

More benefits for residential customers The proposal would double residential bill credits from two years to four years and invest an additional $100 million in EnergyShare through 2038. EnergyShare is Dominion Energy's shareholder-funded energy bill assistance program of last resort that helps people who are having trouble paying their energy bills. The additional two years of bill credits would be funded primarily by redirecting a portion of the original credits that would have gone to data centers, with shareholders funding the remaining amount.

·

Investing in Virginia jobs The companies have committed to maintaining current Virginia employee headcount levels for at least five years after the transaction closes. The enhanced commitments also include an additional 600 new NextEra Energy jobs and approximately 400 new supplier jobs in Virginia.

·

A new co-headquarters building proposed in downtown Richmond A new shareholder-funded NextEra Energy headquarters tower in Richmond, that would be built on the vacant lot across the from the existing headquarters building, would fulfill the company's commitment to maintain dual headquarters in Richmond and Juno Beach and support work in renewable energy development and supply chain management, battery storage operations, nuclear and small modular reactor innovation, enterprise technology and cybersecurity, among others.

·

Building tomorrow's workforce The proposal includes a $100 million workforce development fund to help prepare Virginians for careers in the state's growing energy economy.

·

Strengthening Virginia businesses A new Virginia Supplier Program would provide up to $1 billion annually for five years to support contractors, suppliers and service providers doing business in Virginia and help expand the state's energy supply chain.

What's next: The proposed combination remains subject to regulatory approvals and other customary closing conditions. The enhanced commitments are part of the companies' continued engagement with stakeholders as the regulatory review process moves forward.

What this means for you

More opportunities:

Electricity demand is rising faster than any point in modern history, and the opportunity is unlike anything this industry has seen.

Growth at this scale creates opportunity. If approved, this combination would create a larger platform with greater scale and broader capabilities, giving employees more ways to grow their careers, gain experience in varied businesses and apply their expertise across a wider enterprise. This would open up more career paths, more cross-business experiences and more ways to contribute to work that matters.

The new co-headquarters in Richmond is intended to support growth and a larger enterprise that can create broader opportunities over time. Together, Juno Beach and Richmond will anchor a global energy enterprise.
