Huijue Group’s 4MWh European energy storage project has outperformed expectations, generating €3,000–€5,000 daily with a two-year payback period. The project participates in aFRR/mFRR frequency regulation and day-ahead/intraday market arbitrage, capturing €50–100/MWh price spreads. Combining robust hardware resilience with intelligent EMS control, it operates reliably under extreme -30°C to +50°C conditions, optimizes charge/discharge cycles, and achieves an IRR of up to 27%.
The project was delivered within 65 days, supported by a European on-site team, gaining recognition and attracting partners from Northern and Central Europe. Its success highlights Huijue’s competitive edge in “hardware stability + software intelligence” and contributes to Europe’s energy independence and renewable energy transition, advancing the region’s 57% renewable penetration target by 2030.
Recently, Huijue Group, a global leader in energy storage integration, has delivered impressive operational data for its 4MWh European energy storage project. Leveraging robust hardware resilience and precise insights into Europe's complex electricity markets, the project actively participates in aFRR/mFRR frequency regulation services alongside day-ahead and intraday market arbitrage. Average daily revenues consistently range between €3,000 and €5,000, significantly exceeding projections. This project not only validates Huijue's integrated solutions as pivotal in post-unbundling energy independence transitions but also demonstrates efficient, reliable energy storage pathways for European clients. It has attracted numerous inquiries from Nordic and EU partners, contributing to regional grid stability and advancing renewable energy penetration towards the 57% target.
As Huijue's flagship European venture, this project leverages deep insights into post-decoupling market volatility in the Baltic region (e.g., mFRR demand rising from 189-316MW in 2024 to 1112-1445MW by 2031). Employing modular integrated design, it seamlessly integrates with existing photovoltaic plants to achieve multi-market synergy in frequency regulation and arbitrage. It delivers rapid frequency restoration reserves via aFRR/mFRR (response <100ms, compatible with PICASSO platform's average 129MW activation requirement), charging at low prices in Nord Pool's Day-Ahead (DA) market (night-time <50€/MWh) and discharges at peak times in the intraday market (ID) (encompassing three auctions and continuous trading) (peak >€100/MWh), precisely capturing peak-to-off-peak price differentials of €50–100/MWh.
Project configuration: Two standard 40-foot containerised energy storage systems (1.25MW/2MWh each), total capacity 4MWh. Features include -30°C cold tolerance, ENTSO-E standard compliance, IP65 protection, and Class A fire-rated design. The system flexibly addresses post-uncoupling grid imbalances (aFRR positive peak 1000MW) while optimising DA/ID bids in real-time via EMS. It ensures >5000 cycles under 2-hour full charge/discharge cycles, achieving an IRR of up to 27%. This integrated solution not only reduces the client's initial investment (equipment with a 2-year accounting period) but also maximises capture of Europe's dynamic electricity pricing opportunities, perfectly embodying Huijue's core competitiveness of ‘hardware stability + software intelligence’.
Project returns surpass projections thanks to Huijue's deep European market insights: post-decoupling mFRR peaks at €800/MW·h, while aFRR volatility (std deviation 137MW) amplifies arbitrage opportunities. Dynamic pricing mechanisms (DA/ID spreads of €50-100/MWh) and renewable penetration (57% target by 2030) further unlock potential. Huijue's integrated solution captures a revenue structure comprising 60% frequency regulation, 25% arbitrage, and 15% capacity. Huijue EMS, customised for aFRR/mFRR and DA/ID markets, performs real-time analysis of Nord Pool curves and PICASSO load data to deliver predictive bidding (accuracy >85%) and automated execution. Compared to traditional models, EMS multi-unit coordination reduces imbalance penalties by 10% and significantly boosts IRR to 27%. Within the first month of project launch, five EU developers initiated discussions, validating Huijue's ‘localisation + globalisation’ market strategy.
Presently, Europe's accelerated energy transition and surging PV/wind installations underscore the critical need for energy storage. Building upon this project, Huijue Group invites European clients to explore integrated solutions: from hardware customisation to EMS commissioning, we provide end-to-end empowerment for your green initiatives.
