Grants income mainly relate to ITC cash grants and implicit grants recorded for accounting purposes in relation to the FFB loans with interest rates below market rates in Solana and Mojave projects (Note 17).

Insurance proceeds and other includes $15.3 million of insurance income in 2023 related to an unscheduled outage in Kaxu further to a problem found in the turbine. The Company expects to receive compensation from the insurance company to cover part of the damage and business interruption of the plant. In addition, it includes a gain of $4.6 million related to the sale of part of Atlantica´s equity interest in the Colombian portfolio of renewable energy entities (Note 7).

Income and costs from construction services correspond to the projects ATN Expansion 3 and ATS Expansion 1, which are currently under construction. Given that these projects are included within the scope of IFRIC 12 (intangible assets), the Company has recorded the income and the cost of construction in the consolidated statement of profit or loss (Note 2.3.).

The decrease in other operating expenses in 2023 is primarily due to:


 -
the internalization of the O&M services in the solar assets in Spain during 2022 and 2023. These services are now provided by employees of Atlantica, whose cost is classified within the line “Employee benefit expenses” of the profit and loss statement; and

-
the lower cost of supplies due to lower prices of electricity in the solar assets in Spain in 2023.

The decrease in other operating expenses in 2022, and specifically Raw materials and consumables used, was primarily due to a specific non-recurrent solar project of Rioglass which ended in October 2021.
