To estimate the Net Debt / EBITDA ratio for Iberdrola S.A. for the year 2022, we first identify the components based on the provided facts:

1.  **EBITDA (Beneficio Bruto De Explotacion Ebitda):**
    For the period 2022-01-01 to 2023-01-01, the value provided is **13,228,000,000 EUR**.

2.  **Net Debt Calculation:**
    S&P methodology for Net Debt typically includes total financial debt (current and non-current) minus cash and cash equivalents. Based on the provided data as of 2023-01-01:
    *   **Non-current Financial Liabilities:** 44,216,000,000 EUR
    *   **Current Financial Liabilities:** 25,079,000,000 EUR
    *   **Total Debt:** 44,216,000,000 + 25,079,000,000 = 69,295,000,000 EUR
    *   **Cash and Cash Equivalents:** 4,608,000,000 EUR
    *   **Net Debt:** 69,295,000,000 - 4,608,000,000 = 64,687,000,000 EUR

    *(Note: While S&P adjustments can be complex regarding lease liabilities and derivatives, using the primary reported financial liabilities and cash is the standard approach for this data set.)*

3.  **Ratio Calculation:**
    *   Ratio = Net Debt / EBITDA
    *   Ratio = 64,687,000,000 / 13,228,000,000 ≈ 4.890157

Rounding the result to the nearest two decimal places: 4.89.
