Billions of euros in institutional capital wiped out by structurally flawed contracts, mispriced risk, and negligent advisory. We investigate the failures and pursue recovery for investors who lost money — not on wind, but on deals.
Between 2017 and 2024, institutional investors poured billions into Swedish onshore wind projects, lured by promises of stable infrastructure returns. What they got was the opposite: catastrophic losses driven by structurally toxic contracts that no competent advisor should have endorsed.
The Swedish wind farm sector has accumulated over 13.5 billion SEK (€1.2 billion) in losses between 2017 and 2022 alone, according to research by Christian Sandström and Christian Steinbeck who analysed wind company annual reports. The sector never achieved profit in any single year during that entire period. Loss margins ranged from 19% to 90% of turnover.
The flagship project — Markbygden Ett, Europe's largest onshore wind farm with 179 turbines and 653 MW capacity — exemplifies the disaster. Originally a €800 million investment by Macquarie's Green Investment Group and GE Energy Financial Services in 2017, later acquired 75% by China General Nuclear (CGN), the project accumulated €322 million in cumulative losses and entered debt restructuring in 2023 with SEK 6 billion (€530 million) in total debts.
But Markbygden is not alone. Aldermyrberget (declared bankrupt May 2025), Överturingen (restructured 2024), and the entire Ventus portfolio of five wind farms (813 MW — described in High Court proceedings as "an existential gamble on power generation risk and electricity price risk") all suffered the same structural fate. The Swedish Tax Agency, Norsk Hydro, and GE Energy have all opposed restructuring proceedings — each for their own reasons. The losses are directly traceable to how these deals were put together, valued, and sold to investors.
You did not lose money on wind. You lost money on contracts, structuring, and counterparties. And those losses may be recoverable.
These were not unforeseeable market events. They were known structural risks embedded in how projects were sold and financed.
When all wind turbines produce simultaneously, they flood the market and crash their own electricity price. The more you produce, the less each MWh is worth. This creates a fundamental paradox: when you produce the most, you earn the least.
Projects signed Power Purchase Agreements that required delivery of fixed volumes at fixed prices. When production falls short, operators must buy replacement power at market rates. When they overproduce, the surplus sells at cannibalized prices. The downside is catastrophic; the upside is zero.
The Swedish-Norwegian Electricity Certificate System was designed to subsidize green energy. But as wind capacity exploded, certificates flooded the market. The 2030 target of 46.4 TWh was reached 9 years and 9 months ahead of schedule. Prices collapsed from ~20€ to under 2€ per certificate.
From the Arctic Circle to central Sweden — the same structural flaw, the same result.
The largest wind farm failure in European history. Markbygden Ett was sold to investors as flagship green infrastructure. In 2017, GE and Macquarie's Green Investment Group completed the €800 million acquisition. To secure financing, banks required an ambitious Power Purchase Agreement — a 19-year baseload contract with Norsk Hydro at approximately €25/MWh, requiring delivery of 1.65 TWh annually regardless of actual wind production.
In 2018, CGN acquired GE's 75% stake, entering the project based on financial models and representations made during the sale process. The project then spiralled: losses escalated from €24 million in 2021 to €175 million in 2023, with a loss margin of -193%. The company entered debt restructuring in autumn 2023, and in October 2024 the restructuring plan was approved by Umeå District Court. The PPA with Hydro was voluntarily cancelled, with compensation to Hydro of up to €248 million.
Critically, there is now an ongoing arbitration against GE — potentially covering both turbine performance claims (EPC/availability/power curve) and Share Purchase Agreement disputes (misrepresentation, breach of warranties, wrong financial model, hidden PPA risk). CGN's total losses across six Swedish wind farms: SEK 3.6 billion (€320 million) on investments of SEK 3.4 billion (€300 million). The Swedish Tax Agency, Norsk Hydro, and GE Energy all opposed the restructuring. The Tax Agency argued CGN should bear consequences of a failed "economic investment abroad." Legal advisors for the CGN acquisition included Vinge law firm. The restructuring transferred all future upside — including arbitration claims and sale proceeds — to creditors, leaving CGN's equity at near zero.
The same structural pattern as Markbygden. A fixed-volume PPA with Boliden forced the wind farm to purchase replacement electricity on the open market when wind production fell short. Financial year 2022–2023 saw losses exceeding €33 million. The situation was compounded by Vestas V150 turbine failures — a blade collapse in 2020 traced to a manufacturing defect — which halted approximately 150 similar turbines industry-wide. Boliden and the wind farm are now locked in arbitration over €59.7 million in claims.
Yet another casualty of the fixed-volume PPA model. With a 29-year contract with Norsk Hydro and 15% under-generation, Överturingen was forced to continuously purchase expensive replacement power. Total liabilities to credit institutions reached €381.5 million by end of 2023. The PPA delivery obligations were set at 300 GWh annually (2020–2030) and 550 GWh (2031–2049). The farm failed to deliver required volumes since November 2024.
In early 2025, the PPA was voluntarily terminated, with Hydro entitled to compensation of up to €90 million. The final compensation depends on future sale proceeds and an agreed value-sharing mechanism. As Hydro themselves acknowledged: "the era of long and large PPAs is probably over." The same structural trap that destroyed Markbygden destroyed Överturingen — same counterparty (Hydro), same mechanism (baseload PPA), same outcome (reconstruction and shareholder wipeout).
The landmark litigation. Per the Particulars of Claim, the Ventus Portfolio investment involved "an existential gamble on power generation risk and electricity price risk" — and was "an investment which no competent infrastructure investment manager would have made, whether as a Core Portfolio investment or at all."
Four of five farms sold power under baseload PPAs — fixed hourly volumes at fixed prices. Delivery obligations were set at 60–70% of annual P50 estimates (per Natural Power due diligence, 23 April 2019). The farms were newly built with no operational track record. Leverage was high: 58.6% net debt to enterprise value. Power curve guarantees were unenforceable for Small Zlatan and Big Zlatan because no terrain analysis had been conducted. All assets were located in SE1/SE2 zones — characterized by high wind generation, low demand, and inverse correlation between wind speed and electricity price (the cannibalization effect).
Financial covenants were breached by June 2020 — less than a year after investment. PwC was appointed as debt adviser. Mezzanine facilities were restructured in December 2020, senior loans in June–July 2021. An £11.4m impairment was reported within the first year. By December 2024, the Fund agreed to transfer its interest in Valhalla and Big Zlatan to CGN for nil consideration. There have been zero distributions from the Ventus Portfolio.
This case sets a critical precedent: the claim against the Manager is brought derivatively — NESPF suing on behalf of the Fund because the GP (owned by the Manager) cannot be expected to sue itself. Per Henderson PFI Secondary Fund II precedent, "special circumstances" justify LP derivative action when the GP will not act. If successful, damages are payable to the Fund, and the same logic extends to developers, financial advisors, valuation providers, and arranging banks across every similar deal.
From the Chinese state to a wind farm in northern Sweden — and every advisor, bank, and consultant in between.

Source: Rekonstruktörsberättelse (Aktbil 168). When the wind didn't blow, Markbygden Ett was forced to buy electricity on the spot market to fulfill its PPA baseload obligations. In 2022 alone, this cost €61.5 million — more than the project's total electricity revenue. The PPA was voluntarily cancelled as part of the restructuring, with Hydro entitled to up to €248 million in compensation. PA Consulting valued the wind farm at €380.5 million (going concern, base case) vs €230.7 million (bankruptcy, low case). Even the high going-concern value of €790.6 million would not cover the combined claims of senior lenders (€440M) and Hydro (€248M).
In project finance failures, equity investors rarely recover from the project itself — but often recover through litigation against transaction parties.
On 5 August 2025 — one day before the six-year limitation period expired — Aberdeen City Council filed Claim No. BL-2025-000974 in the Business and Property Courts of England and Wales. The Particulars of Claim, dated 19 December 2025 and signed by Jared Robert Oyston of Brodies LLP, describe the Ventus Portfolio investment as "an existential gamble on power generation risk and electricity price risk" and "an investment which no competent infrastructure investment manager would have made."
The Fund invested £104.2 million total into the 813 MW Ventus Portfolio (five Swedish wind farms). By 30 September 2025, the portfolio's NAV had collapsed to £17 million — a loss of £87.2 million. NESPF's own estimated loss is ~£33.8 million (its 38.1% share), plus lost returns of 7.5–10% p.a. compounded annually. Electricity certificate prices fell 96% between September 2019 and November 2025. The portfolio's EBITDA was 62.9% below budget in 2022. Financial covenants were breached within the first year. Two wind farms (Valhalla and Big Zlatan) were transferred to co-investor CGN for nil consideration in 2024.
The claim against the Manager is brought derivatively — a rare and significant step where an LP sues on behalf of the Fund because the GP cannot be trusted to pursue its own parent company. The Simmons & Simmons analysis (9 March 2026) notes this case gives investors, GPs, and managers a "relatively rare opportunity to benchmark the NESPF claim scenario versus their own experiences." If a pension fund can hold its fund manager accountable, the same logic applies with even greater force to developers who sold projects, banks who structured the financing, and consultants who built the financial models.
The Stockholm Chamber of Commerce (SCC) Arbitration Institute administers high-value energy disputes worth over €100 billion since 2010. The Markbygden arbitration is one of them.
The existence of an active arbitration against GE at the Stockholm Chamber of Commerce (Stockholms Handelskammare) is confirmed by multiple court documents:
Evidence 1 — Rekonstruktörsberättelse (Aktbil 168): The Administrator's Report by Mikael Kubu (Ackordscentralen) states that Markbygden Ett has filed a claim with "Stockholms Handelskammare" (the SCC) and that "GE har gjort ett förskott" (GE has made an advance payment). The report also notes that a separation proceeding ("skiljeförfarande") has been initiated. John Childs has been engaged as external consultant to optimize and drive measures to address "the technical problems that to some extent limit the wind farm's availability" — including evaluation of GE's contractual responsibility.
Evidence 2 — Förteckning över tillgångar och skulder (Aktbil 170): The asset/liability register records "Förskott till Stockholms Handelskammare" (Advance to Stockholm Chamber of Commerce) of SEK 3,074,730 — the arbitration filing deposit. Additionally, the GE Renewable Energy claim is listed as "disputed — amount unknown — counterclaim expected" with a book value of zero, confirming active cross-claims.
Evidence 3 — Dagboksblad (Court Docket): GE Energy AB is listed as creditor party #3 in the reconstruction proceedings (Ombud: Advokat Gustav Kling, Advokat Malin Sanderson). The court records reference the arbitration as a parallel proceeding.
Potential claims against GE include:
(1) Turbine performance shortfall — energy yield below warranted levels, availability guarantees not met, power curve deviations;
(2) EPC contract breaches — construction defects, completion delays, technical problems limiting wind farm availability;
(3) Share Purchase Agreement claims — if the 2018 sale from GE to CGN included misrepresentations about project performance, financial model assumptions, or hidden PPA risk;
(4) Warranty & Indemnity (W&I) insurance — a potential direct source of recovery funds if the original transaction was covered.
According to the Nordic Commercial Arbitration Forum 2025 publication (article by Caroline Falconer, SCC Secretary General, and Raoul J. Sievers), the SCC has administered almost 300 energy sector disputes since 2010, comprising claims worth well over €100 billion. Over 80% were international disputes. The SCC has specifically noted a growing number of disputes involving renewable energy sources, with green technology cases averaging 17 per year between 2019 and 2022 — up from 6.2 per year previously. Of these, 35% arose from construction contracts (such as wind farm EPC agreements).
The SCC also has extensive experience with Chinese parties — administering over 115 cases involving Chinese entities in the last 24 years, with disputes averaging over €100 million per year in the last decade. The SCC's cooperation agreement with CCPIT (China's trade arbitration body, now CIETAC) dates to 1984. Sweden was the first country to recognize the People's Republic of China in 1949. This makes the SCC a natural forum for disputes between CGN (Chinese state-owned) and GE (US-based).
In 2024, the SCC administered disputes with a combined volume of €8.3 billion. Post-M&A disputes are the single most common type, with 57 arbitrations in 2024 alone. The average post-M&A claim was €112 million. Wind farm transactions — combining EPC disputes, performance claims, and SPA/warranty disputes — fall squarely within the SCC's core competency.

Research by Christian Sandström (formerly Jönköping International Business School) and Christian Steinbeck analysed Swedish wind company annual reports from 2017 to 2022 and found:
"The industry cannot produce electricity below market price despite subsidies." Loss margins ranged from 19% to 90% of turnover. The sector never achieved profit in any single year between 2017 and 2022.
