Challenges
Rith Groot, the owner of the hotel, is facing a significant challenge with electricity supply. The hotel is connected to the local grid, but the available capacity is very limited, only 95 kilowatts (kW). This amount of electricity is insufficient to meet the hotel’s basic needs, such as heating, cooling, and other essential operations. To mitigate this issue, the hotel has 700 solar panels on the rooftop. These panels generate a substantial amount of energy, especially on sunny days, producing between 1500 to 2000 kilowatt-hours (kWh).
Limited contracted capacity
In this situation, the hotel has a contracted capacity of 95 kW with the grid, meaning they are allowed to draw up to 95 kW of electricity at any given time. If the hotel’s demand exceeds this limit, they may face penalties or other consequences based on the terms of their contract with the utility company.
The hotel’s energy demand can sometimes surpass this contracted limit during certain times of the day, particularly during peak demand periods when the hotel’s various systems, such as air conditioning or heating.
Solution by Ampowr
Peak Shaving
The AmpiFARM System, with storage capacities of 1100 kW and 500 kW, is designed to capture and store excess energy generated by solar panels during periods of high production. The energy storage system (AmpiFARM) helps the hotel avoid exceeding its grid contract, potentially avoiding penalties, and ensures that their energy needs are met sustainably using a combination of solar power and stored energy. To manage this risk, the hotel uses a peak shaving strategy to ensure that their total energy demand doesn’t exceed the 95 kW threshold. This helps reduce reliance on the grid, lowers energy costs, and ensures a more sustainable and reliable power supply.
Generator Steering
In a backup power situation, when the battery is empty, the generator can provide reliable power during grid outages. This collaboration ensures continuity of supply, optimal operation, and flexibility even under challenging conditions.
Energy Management System
The Ampowr Cosmos EMS is included in the AmpiFARM System. At the Hoge Duin Hotel, peak shaving and generator steering features were implemented to optimize energy usage. By leveraging Cosmos EMS, the hotel monitors real-time energy consumption, solar PV production, and dynamically uses battery storage to reduce electricity demand during peak periods. This approach helps the hotel stay within its contractual limits, avoid penalties, and ultimately achieve significant cost savings.
It also includes generator steering functionality as a backup power option. This feature enables the system to coordinate with a generator during power outages or grid interruptions, ensuring a continuous power supply.
Cosmos EMS includes:
- Dashboard: User friendly Ampowr portal to monitor system information like solar generation, storage, grid and load.
- Monitoring: Based on Service and Maintenance package selection, incl. AmpiHealth module monitoring over 3,000 datapoints to track battery health and system state
- Data Security: Our Software is completely designed, developed and hosted in Europe & is ISO27001 certified, NIS2 EU compliant, has undergone 3rd Party Cyber PENTESTING
- Fleet Management: Our asset fleet management access employs a zero trust security model, allows managing multiple assets, organizing authorization
- Connectivity: In the event of lost connectivity our EMS will continue to perform strategies and collect data through a local backup feature
- Cosmos Partner API: to allow communication between other energy assets or 3rd party strategies.
If your business, whether it’s a holiday park, hotel, or another facility, faces high energy demands, the AmpiFARM System could be a great fit for managing your solar energy more efficiently. By storing excess energy and using it when needed, you can reduce reliance on the grid and improve sustainability.
