The energy infrastructure of an Arctic community

Smart Senja

Introduction

Facing a heightened power demand

Situated in Norway’s Arctic, Senja Island is home to two main communities of around three hundred residents, primarily relying on the fishing industry for livelihood.

Due to expansion in the fishing sector and growing household demands, these communities face significant challenges in their energy infrastructure. Accessible only via country roads and ferry from the mainland, Senja’s communities have long been challenged with inadequate power supply, necessitating innovative solutions.

Finding Cost-effective Solutions

Located at the end of the electrical grid, the Senja communities experienced heightened power demands due to advancements in fish processing technology, requiring consistent voltage stability.

Plans for further business expansion in the region were anticipated to intensify strain on the local grid, typically addressed through costly methods such as grid expansions. Senja’s power grid faced various challenges, including increasing demands from the fishing industry and households, prompting the exploration of cost-effective alternatives like local energy storage systems for managing electricity consumption.

Solution And Benefits

Buffering with Norway’s largest BESS

In response to these challenges, Arva AS, Northern Norway’s largest power supply company, decided to implement a specifically developed BESS solution (Battery Energy Storage Solution).

The solution eases the strain on the existing grid and bolsters the island’s energy resilience by evenly distributing energy consumption throughout the day. This approach mitigates demand peaks and ensures a stable power supply for Senja’s communities. The BESS solution also acts as an energy buffer, charging during periods of low demand and discharging during peak hours, which optimizes energy utilization and promotes sustainability. The solution successfully resolved Senja’s power supply challenges and was appropriately named “Smart Senja”.

Key to the success of Smart Senja were collaborative efforts from the supplier of the BESS units, Rolls Royce Power Systems, and BOS Power, responsible for system integration of battery containers and transformers, including design, project management, delivery and maintenance. Together, they have facilitated the delivery of Norway’s largest BESS solution, comprising three mtu EnergyPack units. Smart Senja, located on Husøy, has significantly enhanced energy accessibility for the entire community, including critical establishments like a local fish farm. With a 10-year Service Level Agreement in place, Smart Senja ensures the smooth operation of energy storage facilities, underscoring BOS Power’s commitment to sustainability and reliability
