Vincent Sorgi
President and Chief Executive Officer at PPL
Thank you, Andy, and good morning, everyone. Welcome to our first quarter investor update. Let's start with our financial results and a few highlights from the quarter on slide four. Today, we announced first quarter reported earnings of $0.39 per share. Adjusting for special items, first quarter earnings from ongoing operations were $0.48 per share compared with $0.41 per share a year ago. This increase was supported by solid results from our newly acquired Rhode Island business as well as lower O&M expenses, partially offset by lower sales volumes due to the mild winter weather and higher interest expense. We remain confident in our ability to deliver on our 2023 ongoing earnings forecast of $1.50 to $1.65 per share with a midpoint of $1.58 per share. Joe will speak to this more in his detailed review of our financial results.
In addition to solid financial performance, we continue to execute on our commitment to provide safe and reliable electric and gas service to our more than 3.5 million customers. This includes managing several significant storms at our utilities, including a severe March windstorm in Kentucky, the third most significant weather event in the last 20 years in our service territory. Our teams with the help of mutual assistance from several of our peers restored power to more than 400,000 LG&E and KU customers. I thank each one of our men and women, as well as all those that provided mutual assistance for their dedication, commitment to safety and demonstrated operational excellence.
From a financial perspective, we received approval to treat nearly $20 million of Q1 O&M costs related to this extraordinary event as a regulatory asset. These types of events emphasize the importance of the investments we are making across our company to harden and improve the resiliency of our network. As the frequency of these events continues to increase, it becomes even more critical to ensure we are taking proactive steps to prepare our distribution and transmission networks. And we look forward to delivering on that goal in the most affordable way possible for our customers. We've also made significant progress during the first quarter in several areas that will improve our operating efficiency, deliver our clean energy strategy and improve service to our customers.
First, we continue to execute our plan in transitioning Rhode Island Energy to PPL systems and remain on track to exit the remaining transition services with National Grid in 2024. We also advanced several key regulatory proceedings, which I'll discuss further on the next couple of slides. Further, we successfully executed more than $3 billion of financings in the first quarter, reducing our interest rate exposure and strengthening our ability to achieve our top-tier earnings growth target. And finally, our execution of approximately $600 million in capital investments during the first quarter, keeps us on track to invest nearly $2.5 billion in infrastructure investments this year.
These investments benefit both customers and share owners as we continue to advance our strategy to create the utilities of the future. As a result, today, we are reaffirming our plans to invest nearly $12 billion in infrastructure improvements through 2026 to modernize our electric and gas networks and replace retiring generation in Kentucky. Looking forward, we remain confident in the low-risk business plan we outlined in January and reaffirmed our projected compound annual earnings per share and dividend growth rate of 6% to 8% through at least 2026. Turning to slide five. We were pleased to secure a positive outcome in our first infrastructure, safety and reliability proceedings before the Rhode Island Public Utilities Commission.
ISR plans are submitted annually in Rhode Island and outline proposed capital investments and related operating costs to strengthen safety, reliability and resiliency of our electric and gas distribution networks. The approved plans address Rhode Island Energy's proposed spending from April 1, 2023, to March 31, 2024. In its decision, the Public Utilities Commission approved $290 million of the approximately $350 million Rhode Island Energy proposed in its ISR filing. This allowed investments on the electric side were largely tied to grid modernization and associated improvements. On the gas side, most of the disallowed investment related to roughly 10 miles of leak-prone pipe replacement. While we believe the disallowed investments are the right projects to better serve our customers, we understand the commission's desire to complete reviews of our grid modernization and advanced meter filings and to make further progress in the future of gas stakeholder proceeding before approving additional spending in those areas.
The investments not approved in this year's ISR plans may be recoverable in future proceedings subject to regulatory approval. This could be through future ISR filings, new base rate cases and/or reopener provisions within the base rate cases that we are currently operating under, particularly related to the grid modernization and AMF projects. Ultimately, we look forward to continued engagement on these matters with the commission, the division of public utilities and carriers and other stakeholders in Rhode Island. Turning to slide six. We continue to progress our generation investment plan in Kentucky and remain confident that this plan is the best path forward for our customers as we plan for the state's energy future. Our plan is more affordable, maintains reliability and represent significantly cleaner energy resources for our customers than continuing to operate the coal units that we have proposed to retire by 2028.
In fact, we estimate that our plan provides nearly $600 million of net present value benefits for our customers compared to continuing to operate these coal units. As we shared in March when Senate Bill four became law, we're confident that the generation replacement plan we filed in December exceeds the standards set by the new law. And as a result, we have not changed our CPCN strategy. As proposed, our plan would replace 1,500 megawatts of aging coal generation with over 1,200 megawatts of new combined cycle natural gas generation, nearly 1,000 megawatts of solar generation and 125 megawatts of battery storage. In addition, our plan proposes the implementation of more than a dozen new energy efficiency programs by 2028. Altogether, the plan represents a $2.1 billion investment in Kentucky's Energy future and the least cost option to reliably meet the needs of our Kentucky customers 24 hours a day, 365 days a year.
As an added benefit, our proposed plan would cut our carbon emissions nearly 25% from current levels while further diversifying our generation fleet. To comply with the new law, we expect to file our retirement request with the KPSC by May 10. Given the law provides the KPSC 180 days to issue a decision on retirement requests, this timing essentially aligns the retirement ruling with the expected decision on our CPCN filing. A decision on our filings is expected by November 6. Again, we're confident the plan we proposed offers the best path forward for the customers and communities we serve.
We don't see any signs of federal environmental mandates easing over time, and we believe investing hundreds of millions of dollars in environmental controls, continue operating aging, uneconomic coal plants is not in our customers' best interest. However, should we be required to make such investments, we do have the environmental cost recovery mechanism, or ECR in place that would enable recovery of these investments outside of base rate cases. We'll continue to actively engage with stakeholders in Kentucky throughout the CPCN process to demonstrate how our plans best meet the needs of our customers. That concludes my strategic and operational update.
I'll now turn the call over to Joe for the financial update.
