This increase was offset (in the November 2024 budget) by downward cost variances relative to the original budget including offshore construction and equipment costs that were forecasted to be under budget due to cost help associated with contract currency hedging. ² Includes higher costs related to UXO removal, undersea cable protection system enhancements, transportation fuel, sea fastener fabrication/installation and other construction and equipment supplier costs 3 Coastal Virginia Offshore Wind (CVOW) Project cost update Total project costs increased to $10.7B from $9.8B, representing a $0.9B or 9% increase This is the first and only increase since the original project budget was submitted to the Virginia State Corporation Commission 39 months ago Increased network upgrade costs are the major driver. These costs: Represented the largest unfixed cost input for the project Are assigned by PJM Do not impact project construction or schedule Were updated based on revised PJM estimate All other costs in aggregate have remained in-line with the original budget Contingency: Increased by $101M since last quarter, now equal to ~5% of remaining project costs Current unfixed costs include finalization of network upgrades by PJM (updated), fuel for transport/installation (no change) and certain project oversight costs (no change)
