Based on the financial and market data provided, the following factors indicate that Acciona S.A. should not be advised to issue hybrid bonds in the near term:

1. **Historical Precedent and Capital Structure:** A critical determinant in advising on hybrid issuance is a company's past reliance on this instrument. The data explicitly highlights that Acciona S.A. has never issued hybrid bonds in the past ("First year of hybrid bond issuance: never" and "Issued hybrid bonds in 2021 or 2022: no"). Companies without a history of issuing hybrids typically have capital structures and financial policies that do not necessitate them. The absence of hybrids currently in their capital structure aligns strongly with a 0% recommendation. 

2. **Cost of Debt vs. Benefit:** While hybrid bonds provide equity credit from rating agencies, they are materially more expensive than senior debt. Looking at the macro data provided, 2022 saw a significant shift upward in baseline interest rates (e.g., 5Y Swap curve moving from negative to 1.726%) and the sub-senior delta spread widened noticeably to 2.295% on average. Under these tighter monetary conditions, the cost of issuing hybrid bonds would materially increase Acciona's overall cost of capital without providing a strictly necessary rating defense.

3. **Adequate Cash Flow and Liquidity:** Acciona demonstrated strong financial performance in 2022, with a notable increase in Operating Cash Flows from €574 million in 2021 to €1,648 million in 2022. Revenue also experienced significant growth, increasing from €8,104 million to €11,195 million, and Net Income climbed to €615 million. Moreover, with Cash and Cash Equivalents standing robustly at €2.36 billion at the end of the year, the company possesses solid internal liquidity to execute its investments without relying on expensive hybrid financing.

4. **Equity Growth:** Total equity expanded from €5.55 billion at the beginning of 2022 to €6.3 billion by the end of 2022. This organic increase in the equity base organically improves leverage metrics, reducing any hypothetical pressure to engineer equity via hybrid debt structures. 

For a company with no prior reliance on hybrid instruments, a growing operational cash flow base, and rising costs of subordinated debt, introducing hybrid bonds is unnecessary and economically inefficient.
