Case Studies
Case List
Textile Factory, China
An energy-intensive textile factory needed to cut electricity costs and emissions. CESC deployed a 2.2MW/4.73MWh large-scale ESS with peak-shaving and load-shifting, lowering bills, stabilizing operations and advancing the plant’s low-carbon, net-zero transition.
Substantial cost savings (millions of RMB annually); higher renewable utilization; supports net-zero transition.

Large-scale C&I ESS
2.2 MW / 4.73 MWh
Thessaloniki, Greece — Event Venue
A mountain event venue with rooftop PV faced strict Zero-Export limits, volatile event loads, and siloed legacy inverters and meters. CESC deployed an all-in-one ESS with a unified EMS retrofit — holding 100% zero-export while maximizing on-site solar self-consumption.
100% Zero-Export compliance; higher PV self-consumption with zero curtailment; lower OPEX via peak-shifting.

Thessaloniki, Greece — Nursing Home
A nursing home with existing solar faced strict Zero Feed-in limits and siloed legacy inverters, while needing stable power for medical equipment. CESC retrofitted a Mercury 233 EU ESS with custom EMS integration — hitting 100% compliance, unlocking stranded solar, and cutting CapEx by avoiding hardware replacement.
100% Zero Feed-in compliance; stranded solar assets activated; CapEx & OPEX savings; reliable power for critical medical equipment.

Kumanovo, Macedonia
A paint manufacturer’s new logistics warehouse with 1MW PV wanted to monetize a steep peak-valley price spread. CESC deployed 10 grid-tied Mercury 233 units (1.05MW/2.33MWh) for PV-paired arbitrage — storing low-cost power and selling at peak to capture the 4x price difference.
Captures the 4x peak/valley price spread (peak ~EUR400 vs valley ~EUR100 /MWh) to maximize grid-sales revenue; robust multi-unit parallel operation.

Austria
An Austrian manufacturer faced fluctuating demand and grid instability that cut its solar ROI. CESC deployed Mercury 233 with an AI-enabled EMS to optimize solar use, stabilize operations and participate in grid services — improving self-consumption, cutting costs, and adding a power-market revenue stream.
Higher self-consumption & solar ROI; reduced energy costs; extra revenue from grid-services / power-market participation; EU certified (IEC, CE).

Strumica, Macedonia
A remote hillside steel factory ran entirely on a costly diesel generator (30 L/day). CESC built an off-grid PV-storage-diesel hybrid with two Mercury 233 units — PV powers daytime load and charges storage for nights, with diesel as manual backup. Proven stable over a 4-day continuous test, delivering energy independence.
Replaced diesel generator (saving ~30 L fuel/day); achieved energy independence; stable off-grid operation proven over a 4-day continuous test.

Davao, Philippines
Households in Davao suffer frequent outages and unstable grid supply. CESC deployed a home-scale low-voltage ESS — 6kW single-phase inverter plus modular Saturn LV5-02 (5-20kWh) with self-developed BMS/EMS — delivering safe, scalable backup power and reducing grid dependence.
Stable backup power during outages; reduced reliance on unstable grid; customizable capacity. CESC’s first residential ESS in the Philippines.
