EV Charging ESS Project: Smart Energy Storage for Sørby Utleie in Norway

Background:

Sørby Utleie, a leading equipment rental company in Norway, is committed to electrifying its operations and offering electric machinery and equipment to its customers. As part of their expansion strategy, they sought an integrated energy solution that would:

• Ensure stable and efficient EV charging for customers.
• Maximize solar energy utilization from rooftop and facade-mounted PV systems.
• Reduce peak demand charges and optimize energy costs.
• Participate in the energy market through spot power trading and balancing services.

Challenges:

1. High Energy Demand for EV Charging:

• The increasing fleet of electric machines and fast chargers placed significant strain on the local power supply.

2. Peak Load and Demand Charges:

• Without an energy storage system, Sørby Utleie faced high costs during peak demand periods.

3. Grid Constraints:

• With limited access to additional grid power, optimizing on-site energy resources became crucial.

4. Energy Market Participation:

• To improve profitability, the company needed a system capable of engaging in spot power trading and frequency regulation markets.

Solution:

To address these challenges, Sørby Utleie partnered with Greenerway AS to implement a comprehensive energy solution, leveraging POWEROAD’s energy storage system. The system featured the FLEX 215 Air Cooling Outdoor Cabinet ESS, with a capacity of 500kW / 1075kWh, providing maximum efficiency and flexibility. Key features include:

✅ Solar Self-Consumption Optimization:

• Surplus solar energy generated from rooftop and facade-mounted PV panels is stored for later use, reducing reliance on the grid.

✅ Peak Shaving & Demand Response:

• The system manages electricity consumption to minimize peak loads and lower demand charges, ensuring a cost-effective operation.

✅ Spot Power Trading & Grid Balancing:

• It enables participation in the spot market and frequency regulation services, turning energy assets into additional revenue streams.

✅ Smart EV Charging Management:

• The system integrates with fast chargers (11kW-360kW) to control charging loads, optimizing energy usage and grid impact.

✅ Seamless Energy Management:

• Fully integrated with an intelligent energy management system (EMS), it allows real-time optimization and value creation.
