Dawnice Energy Storage Case Study – Lisbon: 42% Peak Season Savings for a Historic Boutique Hotel
Project Background
A boutique hotel located in Lisbon’s historic city center, consuming approximately 2,200 kWh per month, faced two major challenges:
Voltage instability – Due to lagging grid upgrades in the old city, power fluctuations impacted guest room comfort, leading to complaints and negative reviews.
Soaring electricity prices – During Portugal’s peak tourist season, electricity prices peaked at €0.28/kWh, significantly increasing operating costs and squeezing profit margins.
The hotel needed a solution that could optimize energy usage within its limited available space – a common constraint for historic buildings with strict preservation requirements.
Policy Support
Portugal’s tourism energy transition plan provided strong financial incentives for this project:
-
✓
Green renovation subsidies for historic buildings – Covering 35% of total investment, making the project financially attractive from day one.
-
✓
Tax breaks on electricity for small businesses – Reducing ongoing operational costs.
-
✓
Lisbon Smart Grid Demonstration Project participation – Providing annual compensation for grid-interactive energy management.
These policies made the Dawnice energy storage solution not only technically feasible but also economically compelling.
Project Introduction
Dawnice deployed a compact, high-performance energy storage system tailored to the hotel’s unique constraints:
The system’s modular, wall-mounted form factor fit seamlessly into the hotel’s limited utility areas without altering the historic building’s structure.
The system smooths grid fluctuations, ensuring consistent power quality for guest rooms – from air conditioning to lighting to Wi-Fi.
The system stores electricity during low-cost off-peak hours and discharges during expensive peak tourist season hours, dramatically reducing electricity bills.
In the event of grid overload or outage, the system instantly switches to backup mode, maintaining full guest services without interruption.
"This system has given our century-old building a new lease on life. During the recent heatwave, while surrounding hotels were forced to cut power due to grid overload, we were still able to provide our guests with complete comfort and service. Through smart scheduling, our peak season electricity costs decreased by 42%, and guest satisfaction significantly improved."
Conclusion
This Lisbon boutique hotel case demonstrates that Dawnice’s energy storage solutions deliver measurable results for historic properties facing modern energy challenges:
- Improved guest satisfaction and operational reliability
For hotels, small businesses, and historic buildings seeking energy independence and cost savings, Dawnice offers a proven, space-efficient solution.
