Planned investments in four projects
The timing and amount of the core capital expenditures and projects for 2021 and the next five years could change based on regulation,
growth, and cost estimates. Additional investments in our infrastructure during and after 2021 that are not incorporated in the estimates
provided will depend largely on additional regulations, growth, and expansion opportunities. Required funds for the investments are
expected to be internally generated and/or financed with long-term debt or equity, as appropriate.
