Sustainable Island Power:
A Microgrid Solution with BESS.
REPLACING DIESEL WITH A FULLY RENEWABLE ISLAND MICROGRID.
A cluster of islands in Dubai required energy infrastructure built entirely from scratch. Hotel complexes were being constructed with 35 GWh yearly consumption and 24/7 operation — with only 4.5 MW diesel generators as the existing energy source.
Diesel logistics to remote islands are costly, unreliable and ecologically unacceptable. The goal was clear: design a sustainable island microgrid powered entirely by renewable energy — with BESS and hydrogen storage ensuring round-the-clock reliability without any grid connection.
The entire system is operated through an advanced EMS that forecasts production, manages storage dispatch, and optimizes Total Cost of Energy (TCOE).
The goal: design a sustainable island microgrid powered entirely by clean, renewable solar energy.
SOLAR + BESS + HYDROGEN — A FULLY RENEWABLE ISLAND SYSTEM.
Volthein designed a multi-layer renewable microgrid combining high-yield solar PV, BESS for daily cycling, hydrogen for multi-day autonomy, and existing diesel generators retained only as last-resort backup — all managed by a single EMS.
- Primary renewable electricity source
- High yield: up to 1,725 kWh/kWp annually
- Rooftop + ground tracker installation
- Feeds direct load and BESS / H₂ charging
- Short-term storage for day-to-night shifting
- Maintains frequency, voltage, power factor
- Backup reserve during low-solar periods
- Automated EMS dispatch 24/7
- Long-term storage in hydrogen tanks
- Sustains 5 days of full island operation
- Fuel cell reconverts H₂ into electricity
- Seasonal buffer for extended low-solar periods
- Retained only as last-resort backup for redundancy
- Not used under normal operating conditions
- Final safety layer — ensures zero downtime under any failure scenario
