Dan Tucker
Chief Financial Officer at Southern
Thanks, Chris and good afternoon everyone. For the second quarter of 2024, our adjusted earnings per share was $1.10 per share, $0.31 higher than the second quarter of 2023 and $0.20 above our estimate. The primary drivers of our performance for the quarter compared to last year were continued investment in our state regulated utilities and warmer than normal weather for our electric subsidiaries. This was somewhat offset by higher interest and depreciation expenses. A complete reconciliation of year-over-year earnings is included in the materials we released this morning.
Our adjusted EPS estimate for the third quarter is $1.30 per share. As Chris noted, all of our businesses experienced a strong second quarter, leading to adjusted financial results meaningfully higher than our estimate of $0.90 per share. The warmer than normal weather in the second quarter contributed to these results, as well as our continued focus on managing operating costs.
Additionally, during the second quarter, we experienced higher than expected weather adjusted electricity sales in our commercial customer class. These higher sales were driven by a combination of continued strength in our local economies, as well as increased usage by many of our existing data center customers. In fact, sales to existing data centers for the quarter were up approximately 17% year-over-year. The strong Southeast economy, including favorable business climates and expansions in manufacturing, continues to drive net end migration and customer growth. For the second quarter, we saw residential customer additions of 14,000 in our electric businesses and 6000 in our natural gas distribution businesses.
We also continue to see strong economic development activity across our electric service territories. The aggregate pipeline for potential new industrial and commercial customers across our three state electric utility footprint includes nearly 200 projects and over 30 gigawatts of potential load over the next decade or so. While it's likely these numbers includes some degree of duplication in potential projects, as some prospective customers are evaluating multiple states that we serve for their facilities, these numbers are significantly higher than what we've seen historically.
About 40% of the projects in the pipeline and 80% of the potential electric load are data centers. In addition to data centers, clean energy and transportation, manufacturing, port related businesses and other heavy industries continue to be attracted to our states due to reliable energy, a diverse workforce, robust transportation networks and a low cost of living, all compelling reasons to locate or expand in our southeastern states. The potential load growth from this pipeline that is reflected in our forecast is currently only a fraction of this full potential.
As a reminder, during our year end earnings call in February, we updated our forecast to reflect projected retail electric sales growth that is expected to accelerate in the latter part of this decade, with a projected growth rate of approximately 6% from 2025 to 2028. The underlying Georgia power projected sales growth is approximately 9% over the same period. In response to this growth, Georgia Power filed and Georgia Public Service Commission subsequently approved earlier this year its 2023 integrated resource plan update.
Since the time of the original filing last year, Georgia powers pipeline of potential large load additions by the mid 2030s has grown approximately 40% and the amount of committed peak demand over the same timeframe has more than doubled, now totaling over 7 gigawatts. As we described in detail on our last earnings call, we continue to execute on our disciplined approach to attracting, serving, pricing and forecasting this potential incremental electric load and we continue to expect that our disciplined approach to pricing this new load should result in revenues that not only cover the incremental cost to serve these new customers, it also provides economic benefits to existing customers.
Chris, I'll now turn the call back over to you.
