Fitch Ratings has affirmed Spain's Red Electrica Corporacion S.A. (Redeia)'s Long-Term Issuer Default Rating (IDR) at 'A-'.

The Outlook is Stable. Fitch has also affirmed Redeia's senior unsecured rating at 'BBB+' and Red Electrica Financiaciones S.A.U' senior unsecured rating at 'A-'.

The 'A-' IDR reflects Redeia's low business risk as the natural monopoly electricity transmission owner and operator in Spain and long-term concessionaire for electricity transmission projects in Brazil, Chile and Peru. Revenue from fiber optic and satellite telecommunications activities weaken the company's regulated business profile, particularly when compared to other European electricity transmission system operators.

The Stable Outlook reflects our expectation of a stable regulatory framework in Spain until 2025, the increase in domestic capex and management's stated support towards a solid capital structure. We expect the loss of revenue from pre-1998 regulated assets from 2024, amid a peaking capex, to be mitigated by announced measures to protect the ratings.

Key Rating Drivers

Leverage Spike from 2024: We expect Redeia's FFO net leverage to increase to 5.5x on average for 2024-25, leaving no headroom under current rating sensitivities. This is up from 4.7x on average for 2022-2023. We view management's strong public commitment to keep net debt/EBITDA below '5.0x' by 2025 - consistent with the 'A-' sensitivities - as key for the rating.

Reintel's Divestment Strengthens Balance Sheet: Redeia in June 2022 completed the sale of its 49% minority stake in Red Electrica's Infrastructures of Telecommunications S.A.U. (Reintel) to Kohlberg Kravis Roberts & Co. L.P for EUR996 million (enterprise value), which implies a valuation of about 20x EBITDA. Redeia will use EUR108 million to its extend dividend policy of EUR1/share by one more year, while most of the proceeds will be used to fund capex. Redeia will inject about EUR900 million in equity at Red Electrica Espana SAU (regopco).

Inflation Adds Pressure: Sustained high inflation could add pressure to Redeia's cash flow as the regulatory framework only provides a partial protection. Full inflation pass-through is only recognised in investments for unique projects (such as interconnections), which represent around 40% of Redeia's plan, while the balance is only half-protected from inflation. Furthermore, the operation and maintenance (O&M) costs are set at beginning of the regulatory period with no interim reviews. So far, inflation risk has been largely contained by Redeia's mid-term procurement policy and efficiency efforts.

Challenging Interest Rate Environment: Redeia's funding cost is expected to increase as new debt, and particularly hybrids, are raised to finance its large capex plan in a scenario of rising interest rates. This contrasts with the allowed return, which is based on fixed nominal weighted average cost of capital of 5.58% during the whole regulatory period (until 2025). Although we expect some impact on FFO, we forecast Redeia will maintain strong coverage ratios until 2025 due to its solid financial profile, strong liquidity (boosted by the Reintel sale) and low fixed-rate outstanding debt.

Transmission Network Plan Approved: The 2021-26 network development plan, approved by the regulator in March 2022, earmarks total investment of EUR7.0 billion, of which EUR5.7 billion will be allocated to reinforce the national network and EUR1.3 billion for international connections. Despite efforts to speed up the issuance of permits and execution, only 40% of the total (EUR2.9 billion) is expected to be used by 2025, with the balance afterwards.

Capex Increasing: Redeia aims to invest UR3.4 billion of capex in regulated activities in Spain for 2021-2025, of which EUR2.9 billion is for grids, EUR0.4 billion for storage and about EUR0.1 billion in new operation systems. This is EUR0.7 billion annually, compared to EUR0.4 billion on average for 2016-2020 (excluding acquisitions). We expect capex to hit EUR520 million in 2022, or 23% above EUR426m in 2021. The company has the goal to step-up capex in regulated activities towards an average annual of EUR1.0 billion after 2025.

Domestic Revenue Decline from 2024: The end of the regulatory life of Redeia's pre-1998 assets (about 40% of its total gross regulated asset base in Spain) will result in a fall in revenue of about EUR240 million from 2024. The fall will not be sufficiently mitigated by a new regulatory asset base coming into operation, opex allowance for useful life extension and other expected growing income or dividend streams. This is one of the main drivers of the leverage increase from 2024 and the temporary increase in the weight of non-regulated earnings to about 20% of total EBITDA by 2025.

Higher Returns After 2025: We expect Redeia's work-in-progress to total about EUR1.3 billion with no returns from these projects until end-2025 when they could add EUR180 million in revenue. That is because the current framework does not remunerate work in progress and generally allows revenue two years after the capex has been incurred, with few exceptions. Redeia and the Spanish regulator are engaged in discussions around these aspects.

Non-Regulated Income to Peak: We expect the contribution of Redeia's telecoms business to rise to about 20% of EBITDA by end-2025 from 15% at end-2021. However, we expect this trend to reverse while grid investments gradually enter into operation and contribute to EBITDA. Regulated earnings from capex will restore the unregulated portion of EBITDA to below 20%, although this is still well above the level at European peers.

Stable EBITDA for 2022: 1H22 EBITDA has increased 1.7% year-on-year. Domestic transmission EBITDA declined by about 2% due to the roll-out of a specific O&M plan for critical assets. However, this has been compensated by positive trading in the international transmission (61% increase) and telecom business (up 4.5%), which benefitted from higher turnover and favourable exchange rates. Fitch forecasts Redeia's 2022 EBITDA similar to 2021 levels.

Derivation Summary

Red Electrica's has a robust business profile with limited price and volume risk similar to other system operators such as Germany's Amprion (BBB+/Stable) and REN (BBB/Stable) in electricity and Italy's Snam (BBB+/Stable) and Enagas (BBB/Stable) in gas transmission.

Amprion and Snam's ratings are one notch lower than Red Electrica's reflecting the company's lower leverage. Snam has a higher debt capacity than Red Electrica given our view on the stability, long record and better protection from inflation of the Italian regulator, as well as lower levels of non-regulated activities. Amprion has higher debt capacity given that it is a fully regulated business with an overall better framework. REN is two notches lower than Red Electrica exclusively reflecting higher leverage.

Enagas is Spain's gas transmission system operator with broadly similar regulatory considerations and geographical presence to Red Electrica. The two-notch difference in ratings mainly reflects Enagas's higher business risk, following the acquisition and dividend cut from Tallgrass Energy Partners, LP (BB-/Stable) that affects its debt capacity.

Key Assumptions

Transmission revenue for the 2021- 2025 is calculated based on the application of the methodology contained in the circular 5/2019 and 7/2019 approved by CNMC on December 2019.

Allowed rate of return of 5.58% from 2021 onwards (from 6.0% in 2020).

Revenue for the system operator activity of EUR75 million on average.

Fibre-optic and technology services revenue to average EUR150 million a year up to 2025.

International revenue to average around EUR65 million a year for 2022-2025.

Revenue from satellite subsidiary Hispasat forecast to average about EUR230 million a year in 2022-2025.

Dividends from international investments to average EUR13 million in 2022-2025.

Total capex at about EUR3.9 billion for 2022-2025.

Dividends in line with announced policy of EUR1 per share for 2021-23 and EUR0.8 per share from 2024.

RATING SENSITIVITIES

Factors that could, individually or collectively, lead to positive rating action/upgrade:

A positive rating action may arise from FFO net leverage remaining consistently below 4.5x or FFO interest coverage increasing to about 5.0x or above, both on a sustained basis.

Factors that could, individually or collectively, lead to negative rating action/downgrade:

An increase in FFO net leverage to above 5.5x and FFO interest coverage of about 4.0x or below, both on a sustained basis, as a consequence of adverse regulatory changes, higher capex or failure to implement sufficient mitigation measures, at or beyond those included in the 2021-2025 business plan.

A growing share of non-regulated EBITDA above 20% could lead to a revision of leverage guidelines for the rating. This would be due to our view of a changing business profile towards riskier activities.

Best/Worst Case Rating Scenario

International scale credit ratings of Non-Financial Corporate issuers have a best-case rating upgrade scenario (defined as the 99th percentile of rating transitions, measured in a positive direction) of three notches over a three-year rating horizon; and a worst-case rating downgrade scenario (defined as the 99th percentile of rating transitions, measured in a negative direction) of four notches over three years. The complete span of best- and worst-case scenario credit ratings for all rating categories ranges from 'AAA' to 'D'. Best- and worst-case scenario credit ratings are based on historical performance.

Liquidity and Debt Structure

Strong Liquidity: At June 2022, Red Electrica's cash and cash equivalents amounted to EUR1,208 million and undrawn committed lines to approximately EUR1.78 billion, of which EUR1.61 billion is due after June 2023. The available liquidity is enough to cover debt maturities of around EUR1.3 billion and expected negative FCF after acquisition and divestures of around EUR0.7 billion in the next 24 months.
