Powering renewables research with ultra-low emission microgrid

Client: Energie Beheer Nederland (EBN)

Location: Netherlands

Sectors: Utilities

The challenge

Extracting geothermal energy from depths of 630 metres 

Energie Beheer Nederland (EBN) are committed to developing sustainable energy and asked for our support to help power their ground-breaking geothermal research project. Geothermal energy is heat that’s generated and stored in the earth. 

The project involves researching several onshore wells to identify whether they are suitable for the extraction of geothermal energy. The drill would bore through earth layers that were 260 million years old. If successful, the wells could provide a reliable and constant source of low-carbon and renewable heat that is not dependent on weather conditions.

Project details

Battery energy storage system 1 x 300 kVA
Transformers 690 V
years earth layers 260 million
PowerMX2 twin engine Stage V generators 3 x 1250 kVA

The solution

Twin engine technology and battery storage for high capacity and load on demand

We needed a solution that could provide up to 2600 kW peak power for the drilling rig, while meeting ambitious emissions targets that go beyond the Netherlands government’s stringent regulations. A conventional temporary power solution would not have met such stipulations, meaning the project would have had to cease operations.

We presented several emissions reduction alternatives for our client to review. The final microgrid solution consisted of our latest PowerMX2 twin engine Stage V generator on a load on demand application alongside a battery. This solution provided peak power for the drill, while reducing emissions during lower loads or rig idle.

The result

Boosting sustainability whilst providing 90% NOx reductions

The project was a joint success. We were proud to play our part in helping to power this vital, sustainable research and bring geothermal energy one step closer. As well as hitting the targets set out by EBN, we were able to provide a reduction in NOx emissions of up to 90%. Through Greener Upgrades we deliver sustainable technologies and techniques that help to minimise carbon emissions and maximise fuel savings. 
“This project allows us to assess the possibilities of geothermal heat, and therefore increase the chance of successful projects to heat homes and buildings in the Netherlands. This is part of our commitment to sustainability, something shared by Aggreko which makes them a solid partner for our exciting research.”

“Unlike other renewables such as solar and wind, geothermal energy is not weather dependent, making it a sustainable and reliable commodity, and incredibly important for creating a sustainable energy future – something we are heavily invested into at Aggreko. This project is a live example of how we are supporting the energy transition through our sustainability framework, Energising Change. It essentially sets out a series of initiatives and investments which will enable regions, and organisations, to scale up their approach to a renewable energy future. We are beyond proud to have been involved in enabling this particular project with EBN.”
