Steven Ridge
Senior Vice President and Chief Financial Officer at Dominion Energy
Thank you, Bob, and good morning.
Our second quarter 2023 operating earnings as shown on Slide 6 were $0.53 per share. As you're aware, we revised our second quarter guidance on June 30 from a range of $0.58 to $0.68 per share to a range of $0.44 to $0.50 per share to reflect our expectation for the negative impact of weather and unplanned outages at Millstone.
First on weather. I'll just note that second quarter weather was the mildest relative to 15-year normal in the last 50 years and amounted to an $0.08 headwind during the quarter. With regard to Millstone, we experienced both an increase to the duration of a planned outage at Unit 2 and an extended unplanned outage at Unit 3, which taken together amounted to an additional $0.08 headwind during the quarter. These outages are uncharacteristic for Millstone, which has a strong history as the largest zero-carbon electricity resource in New England of exemplary safety and reliability performance.
Senior leadership, including Eric Carr, who recently joined as our new Chief Nuclear Officer, after several years at PSEG, most recently as their Chief Nuclear Officer, has instituted a thorough and peer-involved review of the plant's operating practices to ensure that despite the unusual nature of these outages, the station is prepared to consistently operate at its maximum potential for years to come.
Higher sales and lower O&M contributed to the modest outperformance relative to the revised guidance range. Relative to the second quarter last year, positive factors include higher sales and O&M timing; negative factors include higher interest expense, lowered DEV margins for certain utility customer contracts with market-based rates, higher depreciation, the absence of solar investment tax credits, and as discussed, weather in Millstone.
Second quarter GAAP results reflect a net income of $0.69 per share, which includes the positive non-cash mark-to-market impact of economic hedging activities and unrealized gains in the value of our nuclear decommissioning trust funds. A summary of all adjustments between operating and reported results is included in Schedule 2 of the earnings release kit.
Moving now to guidance on Slide 7. Given the pending business review, we are not providing full-year 2023 earnings guidance. For the third quarter 2023, we expect operating earnings to be between $0.72 and $0.87 per share. Last year's third quarter operating earnings were $1.11 per share.
Let me walk through some of the key drivers of this year-over-year change, all of which we've identified previously. First, approximately $0.12 from higher interest expense as a result of higher market rates. Approximately $0.09 related to the $350 million Rider revenue reduction, which became effective July 1. Approximately $0.06 related to the removal of Cove Point from operating earnings effective July 1, due to the sale agreement. About half of that is related to the absence of a $0.03 help this quarter relative to last year from higher variable revenue and other additional services. This number also doesn't capture the impact of expected lower interest expense due to parent debt retirement from sale proceeds later this year, which we estimated approximately $0.05 to $0.06 per share on an annualized basis. Approximately $0.04 from the elimination of non-regulated solar investment tax credits. And approximately $0.02 from an O&M related to the Millstone fall planned outage.
Before moving to sales trends, let me emphasize one of our business review priorities. A durable high-quality and predictable long-term earnings growth profile with consistent execution, we recognize the critical importance of meeting any post-review financial targets, even if and when unexpected headwinds occur.
Turning to Slide 8, I'll address electric sales trends. When we announced the review in November, we described the long-term scope and duration of our resiliency and decarbonization capital investment opportunity as very much intact. In May, we discussed PJM's updated electric load projections that forecast summer low growth in the DOM Zone of 5% per year for the next 10 years. Those estimates reflect the very robust demand growth we're observing in real-time across our system. Weather-normalized sales in Virginia increased 5% over the last 12 months through June as compared to the prior year. For full-year 2023, we expect the growth rate at DEV to be around 5%.
It's worth noting that just last week, we registered new summer peak demand records on consecutive days. And just as we expect, our customers likely would have no idea given the high-quality operational performance delivered by our colleagues under these demanding load conditions.
The unique intersection of industry-leading demand growth and strong policy support for resiliency, decarbonization, affordability and economic growth, combined with the durability of the Virginia regulatory structure, represents an unprecedented opportunity for our company, our customers and our capital providers. It will drive growth for many years to come, demand prudent capital allocation and require a strong balance sheet, which brings me to my next topic, credit.
Our commitments and priorities with regard to credit are unchanged. I'll reiterate them here. As we've discussed, despite meaningful qualitative improvement over the last several years, our credit metrics need strengthening. We want to emerge from the review with the ability over time to consistently meet and exceed our downgrade thresholds even during temporary periods of cost or regulatory pressure. As part of the review, we're analyzing the most efficient sources of capital to improve our balance sheet and fund our robust capital investments, while seeking to minimize any amount of external equity financing need.
As Bob mentioned, the Cove Point transaction was strongly credit accretive, improving consolidated FFO to debt as measured by Moody's by 70 basis points. Post-sale comments by the rating agencies with whom we maintain frequent engagement highlighted the credit-positive nature of the announcement, but noted as we expected that additional steps are required to ensure that our metrics sustainably meet and exceed our downgrade thresholds going forward. As it relates to credit, the objective of the business review is to create a robust balance sheet foundation that can both withstand potential temporary headwinds, and also sustainably support the significantly elevated levels of regulated capital investment over the next few years.
With that, I'll turn the call back over to Bob.
