Client Case

BUYER : Desert Agricultural Complex

LOCATION:         Abu Dhabi, United Arab Emirates

INSTALLTION DATE:  Nov .2023

QUANTITY:         1 SETS

SYSTEM TYPE:      500Kw Off-grid battery system

DESCRIPTION:      A large agricultural complex in the desert hinterland of southern Abu Dhabi, UAE, covering about 200 hectares and comprising high‑tech greenhouses, cold‑chain storage, and produce processing, had long relied on multiple diesel generator sets for electricity – incurring huge fuel costs and carbon emissions. GREEF Energy custom‑designed a complete off‑grid wind power system featuring a 500 kW low‑speed permanent magnet generator, GREEF PCTC smart controller, GREEF AC PCS multi‑function converter, and a 2.5 MWh battery energy storage system. After one year of operation, the system generates approximately 2.15 million kWh annually, fully replaces diesel generation, saves about AED 900,000 (approx. USD 245,000) per year in fuel costs, and reduces CO₂ emissions by about 1,150 tonnes – fully aligned with the UAE’s National Energy Strategy 2050 to triple renewable energy capacity to 19.8 GW.

System features: 100% off‑grid operation, remote monitoring via APP and PC for real‑time generation, storage status, and load data; supports customised sensor control functions.

BUYER : TSF Manufacturing Plant

LOCATION:         New South Wales, Australia

INSTALLTION DATE:  Apr .2025

QUANTITY:         1 SETS

SYSTEM TYPE:      100kw  On-grid system

DESCRIPTION:      The Manufacturing Plant in New South Wales, Australia, has access to a perennial irrigation canal with stable water flow. The Manufacturing Plant previously relied entirely on grid power, incurring high electricity costs. GREEF Energy custom‑designed a pure grid‑connected hydro system (without batteries) comprising a 100 kW low‑speed permanent magnet generator, a GREEF AC PCS multi‑function converter, and a GREEF PCTC‑100 kW smart controller. After one year of operation, the system generates approximately 520,000 kWh per year, reduces electricity bills by 82%, saving about AUD 68,000 annually, while enabling self‑consumption and surplus feed‑in to the grid.

System features: Battery‑free configuration – simple structure, low cost, direct grid connection, self‑consumption plus surplus feed‑in, and remote monitoring via APP and PC.

BUYER : GFM Food Processing Plant

LOCATION:         Limburg, Netherlands

INSTALLTION DATE:  June 2025

QUANTITY:         1 SETS

SYSTEM TYPE:      100Kw Grid-Connected Hydropower System

DESCRIPTION:      A Food Processing Plant in the province of Limburg, Netherlands, located adjacent to a branch canal of the Maas river with year-round stable irrigation canal flow and existing weir infrastructure, had long relied on grid power with high electricity costs and faced grid congestion challenges. GREEF Energy customized a 100kW low-speed Permanent Magnet Generator + Frequency & Voltage Regulator + PCTC-100kW intelligent controller low-head grid-tied hydropower system (battery-free), retrofitting existing canal irrigation infrastructure. After one year of operation, the system generates approximately 430,000 kWh annually, reducing electricity costs by 76%, saving about €33,000 per year, and qualifying for the Dutch SDE++ renewable energy operating subsidy.

System Features: Battery-free configuration, simple structure, low cost, direct grid connection, self-consumption with surplus export; APP and PC remote monitoring support; eligible for Dutch SDE++ operating subsidy .

BUYER : HHI Packaging factory

LOCATION:         Fergana Valley of Uzbekistan

INSTALLTION DATE:  May 2024

QUANTITY:         1 SETS

SYSTEM TYPE:      100Kw Grid-Connected Hydropower System

DESCRIPTION:      Packaging factory in the Fergana Valley of Uzbekistan, located adjacent to an irrigation canal branching from the Syr Darya River with year-round stable water flow, had long faced unstable grid coverage and intermittent power supply. GREEF Energy customized a 100kW low-speed Permanent Magnet Generator + GREEF AC PCS multi-functional converter + GREEF PCTC-100kW intelligent controller + battery energy storage system hybrid off-grid/grid-tied hydropower system. After one year of operation, the system generates approximately 390,000 kWh annually, reducing electricity costs by 74%, saving about UZS 285 million per year, enabling flexible switching between off-grid self-sufficiency and grid-tied surplus sales, and qualifying for Uzbekistan's "Green Energy" certificate scheme.

System Features: Hybrid off-grid/grid-tied mode—grid-tied operation with surplus export during normal grid conditions; automatic switch to off-grid mode with battery supply during grid outages; APP and PC remote monitoring support; eligible for Uzbekistan Green Energy certificates and equipment purchase subsidies.

BUYER : CWE Large-Scale Mixed-Use Projects

LOCATION:         Los Ríos Region, Chile

INSTALLTION DATE:  May 2023

QUANTITY:         1 SETS

SYSTEM TYPE:      300Kw Off-grid Hydropower System
