JCE supports Greyhope Bay Project

"The ‘Dolphins at the Battery’, project will enhance access to Torry Battery, a site with a unique heritage, spectacular panoramic views of Aberdeen’s city and coast, and the best view of our charismatic bottlenose dolphins - the largest bottlenose dolphins found anywhere in the world".

Greyhope Bay entered into a dialogue with JCE Energy in January 2020 due to our vast experience working with renewable energy projects and supporting off-grid power requirements, while having a presence locally in Aberdeen.

With the site location of unique heritage and the project aiming to deliver an exceptional marine experience centre to the community, there was a focus on achieving a zero-footprint and sustainable design. Additionally the intent was to promote behavioural changes in waste and the circular economy.

This was naturally something we were intrigued by, with their work focusing on delivering sustainable power generation through the use of alternative energy solutions. Furthermore, we believed that Greyhope Bay could achieve their sustainable model by utilising a reliable and cost-effective off grid green energy system.

As the 'Dolphins at the Battery' phase will engage the wider community, Greyhope Bay highlighted the importance of providing educational opportunities incorporating science, wildlife, technology, history and art while showcasing an impressive facility.

We were excited to be involved in a project which offers various opportunities and promotes environmental awareness to the communities within the region. We believed in providing support through working alongside the Greyhope Bay team to utilise our wide expertise and innovative green technology - an area we are highly passionate about.

After conducting an initial feasibility study of the site next to the Torry Battery, we pledged full support in the design & manufacture of a robust power system which would compliment the viewing platform and cafe to be built using recycled shipping containers.

With no grid connection available on site, supplying power to the remote facilities remains a challenging aspect of the project and one which we have valuable experience in.

Initial project challenges:

  • No onsite power or water
  • Visual impact of wind turbine
  • Impact on historic monument
  • Undesirable fossil fuel approach
  • Analysis and prediction of facility energy consumption

Initial proposal: Hybrid Power System

  • Solar
  • Battery
  • Advanced control system
  • 2 x 1kW wind turbines
  • Remote system operation / monitoring

Our Chairman, Jim Craig, discusses the challenges and proposal for the project with Greyhope Bay MD, Fiona McIntyre, in this video interview.

April / May 2020 - Proposal Challenges

April / May 2020- Proposal Challenges

When the initial proposal was submitted, historic Scotland rejected the wind turbines due to the visual impact on the community.

This was subject to a site visit to assess the situation and review the equipment involved, which was inevitably delayed by the impact of COVID-19.

A revised proposal has since been presented and accepted in order to allow the project to proceed.

To facilitate this shift in the reduction of power availability, a silent generator is to be installed to charge the batteries during night-time hours with the battery system increasing accordingly.

We proceeded to detailed discussions with GHB to determine an acceptable load level for the facility, with adjustments made to ensure the equipment was going to be viable and practical.

June 2020 - Design Phase

During this period, the design phase of the control systems, including the hardware, communication package and the philosophy of operation, was carried out.

The long lead items (battery cells, solar panels and inverters) were also ordered.

July 2020 - Arrival of Solar Panels and Battery Charger

The month of July saw the arrival of the 270W Solar Panels which are to be positioned on the roof of the repurposed shipping containers and placed at an optimum angle to receive the maximum power from the available sunlight in Aberdeen. Fiona also made a visit to JCE's premises to check on progress and discuss further updates with the team.

The Battery Charger was also delivered (completed) and will be utilised both at night or during periods of no sunlight to ensure the battery is sufficiently charged to supply reliable power to the loads in the facility.

August 2020 - Delivery of Filtration Unit and Silent Generator

The Filtration Unit collects rain water and has filtration capabilities to make it suitable for drinking. The unit has low energy consumption (works on an on-demand basis) and a compact design (the dimensions of a domestic fridge). The design of the Filtration Unit makes it suitable for off-grid applications, where it cannot be connected to the water mains.

The Silent Generator was also delivered in August. It is an integral part of the system as it will be used to re-charge the batteries during periods of darkness, or in the event that abnormal high energy consumption is causing the batteries to deplete quicker than expected.

The system is designed to work automatically, using a PLC, which constantly monitors the system parameters (battery voltage, energy consumed and generated) in order to optimally re-charge the batteries, guaranteeing the constant energy supply.

The purpose of the Solar Charge Controller is to give additional charging capacity to the batteries from the sun. It collects the solar irradiation during the daytime and transfers the energy into the system. This additional energy is coming from a complete renewable source (the sun), providing the first step in achieving a truly sustainable facility.

The Power Inverter Unit transfers the voltage from the batteries (DC Voltage) to the load (AC Voltage), allowing the equipment to run on the same power supply which you would find in your home.
