Procedural Posture

This document is the Counter-Memorial on the Merits and Memorial on Jurisdictional Objections submitted by the Respondent, the Kingdom of Spain, in an ICSID arbitration (Case No. ARB/15/16) initiated by BayWa r.e. Renewable Energy GmbH and BayWa r.e. Asset Holding GmbH. The dispute arises under the Energy Charter Treaty (ECT) and concerns regulatory changes in Spain's renewable energy sector.

Jurisdictional Objections

Spain raises two principal objections to the Tribunal's jurisdiction. First, it argues a lack of jurisdiction ratione personae on the grounds that the dispute is an intra-EU matter, as both the Claimants (German entities) and the Respondent are members of the European Union. Spain contends that the dispute resolution mechanism under Article 26 of the ECT does not apply to intra-EU disputes, and that EU law, which provides its own system of investor protection, prevails. Second, Spain objects to the Tribunal's jurisdiction ratione materiae over claims related to the introduction of the Tax on the Value of the Production of Electrical Energy (TVPEE). It asserts that Article 21 of the ECT expressly carves out taxation measures from the scope of the substantive protections in Article 10(1) of the ECT, thereby precluding arbitration of such claims.

Arguments on the Merits

On the merits, Spain argues that it has not breached its obligations under the ECT, including the standards of Fair and Equitable Treatment (FET) under Article 10(1) and the prohibition on expropriation under Article 13. The Respondent posits that the challenged regulatory measures were a legitimate, reasonable, and proportionate exercise of its sovereign right to regulate its economy, particularly in the strategic energy sector.

Spain contextualizes the reforms within a severe economic crisis, a substantial and growing electricity tariff deficit, and a history of over-remuneration in the renewable energy sector. It contends that the foundational principle of Spain's regulatory framework has always been the provision of a "reasonable return," which does not equate to a guarantee of a stable or frozen remuneration regime. The measures were therefore predictable and necessary to ensure the financial sustainability of the Spanish Electricity System (SEE). Spain further argues that it has not breached the umbrella clause, as the legislative and regulatory acts cited by the Claimants do not constitute specific commitments undertaken with the investors. Finally, Spain requests the Tribunal to decline jurisdiction or, alternatively, to dismiss all claims on the merits and award costs in its favor.
