Eurus Energy Holdings Corporation v. Kingdom of Spain
ICSID · Investment (ICSID and treaty) · Spain · 14 Nov 2022
Why it matters
This award is one of many ICSID cases against Spain over retroactive cuts to renewable energy incentives. It clarifies that the claw-back mechanism breached the FET standard, even though the overall reasonable return was maintained. The decision on damages methodology, including the valuation date and discount rate, provides guidance for calculating compensation in similar investment treaty disputes.
Summary
Eurus Energy Holdings Corporation, a Japanese company, invested in wind farms in Spain under a regulatory framework that guaranteed a feed-in tariff (FIT) providing a reasonable return. In 2013, Spain introduced measures that included a 'claw-back' feature: if a plant had received subsidies above a certain level in the past, future subsidies would be reduced to offset the excess. The Tribunal had previously found that this claw-back breached the fair and equitable treatment (FET) standard under Article 10(1) of the Energy Charter Treaty (ECT). In this final award, the Tribunal determined the quantum of damages. The key issues were: (1) how to calculate the revised net asset value (NAV) as of July 2013 to eliminate the claw-back effect; (2) the appropriate valuation date and discount rate; and (3) interest. The Tribunal rejected Spain's argument that no damages were due because the plants still received a reasonable return overall. It held that the claw-back itself was unlawful and required compensation. The Tribunal adopted a discounted cash-flow (DCF) methodology, using a valuation date of 1 June 2021 (the date of the liability decision) and a discount rate based on the weighted average cost of capital (WACC). It awarded EUR 106.2 million, plus interest calculated using a 2-year Spanish sovereign bond rate compounded annually from 1 June 2021. The Tribunal also allocated costs 60% to Spain and 40% to Eurus, resulting in a net cost award of USD 4,332,197.16 to Eurus.
