Battery Energy Storage Systems
for Hotels (challenges and solutions)

Table of contents

Hotels in the Netherlands face energy challenges due to several factors. Firstly, the country’s energy prices have increased in recent years, impacting businesses that rely heavily on energy, like hotels. Additionally, many hotels are housed in older buildings with poor energy efficiency, making it difficult to meet current energy demands sustainably.

The Netherlands also has strict regulations regarding carbon emissions, pushing businesses to reduce their energy consumption while maintaining guest comfort. Hotels are under pressure to adopt renewable energy sources, but the transition can be costly and complex, especially for smaller establishments.

Furthermore, the growing demand for electric vehicles has led to more hotels needing to invest in charging stations, adding to their energy load. Finally, energy grid limitations in some areas can lead to supply constraints, making it harder for hotels to manage their consumption effectively.

To address the energy challenges, many hotels in the Netherlands are turning to Battery Energy Storage Systems (BESS) as a solution. BESS helps hotels manage energy consumption more efficiently by storing excess energy during off-peak hours and using it when demand is higher. This not only reduces energy costs but also ensures a stable supply of energy, helping hotels avoid grid instability and reduce reliance on expensive peak-time electricity.

By integrating BESS with renewable energy sources like solar or wind, hotels can become more self-sufficient, lowering their carbon footprint and improving sustainability. Additionally, BESS can enable hotels to participate in demand-response programs, allowing them to sell excess energy back to the grid, further offsetting costs.

Investing in BESS can be a smart long-term solution, providing financial savings and helping hotels meet environmental regulations while improving overall energy efficiency.

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.

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.

Roompot Callantsoog faced two primary challenges:
Variable Energy Demand
The holiday park experienced significant fluctuations in energy usage, peaking during holiday seasons when guest occupancy surged. This variability presented a complex challenge in grid capacity.

Grid Congestion
The local energy grid was subject to congestion, particularly during peak periods, leading to high energy surcharges. These charges represented a substantial and unpredictable operational cost.

In response to these challenges, Roompot Callantsoog implemented the AmpiFARM 10ft Battery Energy Storage System. This system was designed to store energy during off-peak hours, when tariffs were lower, and discharge during peak times to provide a stable and cost-effective energy supply.

The deployment of the AmpiFARM system had several significant outcomes:

• Uninterrupted Power Supply: The system guaranteed a consistent power supply during peak usage times, thereby enhancing guest satisfaction.
• Energy Cost Reduction: By reducing reliance on the grid during peak times, the holiday park minimized exposure to high energy tariffs.
• Operational Efficiency: Intelligent energy storage and distribution led to more effective use of resources and operational cost savings.
• Sustainability: The integration of the AmpiFARM system lowered the site’s carbon emissions, aligning with Roompot Callantsoog’s commitment to environmental sustainability.
