To calculate the Net Debt / EBITDA ratio for Iberdrola S.A. for the year 2022 (based on the provided 2022-01-01 to 2023-01-01 data), we follow the S&P methodology, which typically defines Net Debt as total financial debt minus cash and cash equivalents.

**1. Identify EBITDA for 2022:**
From the provided facts, "Beneficio Bruto De Explotacion Ebitda" (EBITDA) for the period 2022-01-01 - 2023-01-01 is 13,228,000,000 EUR.

**2. Identify Net Debt for 2022:**
Net Debt is generally calculated as Total Debt minus Cash and Cash Equivalents. Based on the 2023-01-01 balance sheet (representing the end of 2022):
*   Noncurrent Financial Liabilities: 44,216,000,000 EUR
*   Current Financial Liabilities: 25,079,000,000 EUR
*   Total Financial Liabilities: 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: In some interpretations, "Noncurrent Derivative Financial Liabilities" and "Current Derivative Financial Liabilities" are included in debt calculations. However, standard S&P definitions for industrial/utility credit ratios typically focus on financial borrowings. If we exclude derivative liabilities (3,690,000,000 and 3,398,000,000 respectively) as they are often mark-to-market valuations, the calculated financial debt remains 64,687,000,000 EUR.*

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