Heat Pump Plus

Heat pumps can offer a viable alternative for many homes to transition from fossil fuel-based heating systems to a much cleaner system.

There is currently little data on how heat pumps operate over time after their installation, and what factors impact their performance. Community Energy Scotland (CES) are looking to target this head on with the Heat Pump Plus (HPPlus) project.

What will the project do?

HPPlus is looking to gather high quality data on the factors which dictate how effective heat pumps operate, and the impact energy efficiency measures can have. The project will collect information on the heating system in place; deploy energy monitoring equipment (to monitor the heat pump’s electricity consumption and in some cases heat output); capture participants’ heating habits as well as perception and understanding of the heat pump system. From this information, HPPlus will, where possible, propose measures to increase the performance of their heating system which could help contribute to energy savings.

Participants with installed energy monitoring equipment will have access to the real time data being collected. The equipment will then be gifted at the end of the project to allow continued monitoring by the homeowner.

The project will first focus efforts on Orkney, as a test bed before for the project’s approach, ahead of potential roll out in other regions.

Who is this project for?

  • Those with properties in Orkney which are occupied all year round with heat pumps, or those who are scheduled to have a heat pump installed in the next 6-months
  • Homeowners who would like assistance in understanding how effectively their heat pump is operating
  • Those who are happy to actively contribute towards the data collection and are open to energy efficiency measures

How can I take part?

Western Isles Energy in Motion (WIEiM)

Energy in Motion is a year-long project, started in 2020,  aiming to raise awareness of sustainable transport opportunities amongst community groups across the Western Isles. Through this project Community Energy Scotland is able to provide an advice and support service for Western Isles community organisations who are interested in sustainable transport projects. 

A survey of the organisations was conducted initially, to gauge the levels of interest, and the knowledge of and experience with sustainable transport projects.  More than 10 community groups have since approached us for support with related funding applications. 

As part of WIEiM Community Energy Scotland is planning sustainable transport awareness events and try out sessions for e-bikes and electric vehicles in 2021. This includes a Western Isles Sustainable Transport festival, a month long event which would take place in Spring 2021 and combine various challenges and events to raise awareness about sustainable transport. These activities will of course be based around any covid restrictions that may be in place at the time.  

We have embarked on the delivery of a WIEiM webinar series, focusing on sustainable transport opportunities for groups in the Western Isles – these webinars have been designed and delivered in lieu of in-person awareness raising events which have been postponed till 2021. 

The majority of funding for WIEiM is from Paths for All, with further support from the Western Isles Development Trust, the Robertson Trust and the Pebble Trust. 

Heat Smart Orkney

HSO – smart community energy

Orkney suffers high levels of fuel poverty, and lost generation and revenue due to grid curtailment, while having some of the highest wind generation capacity. For the islands of Rousay and Eday, an average of >45 % of production (nearly £500k lost revenue combined per annum) when curtailment first started to impede generation. The Heat Smart Orkney (HSO) project (funded by the Scottish Government’s Local Energy Challenge Fund) provides a smart solution by connecting the community owned wind turbines to the heating of local homes.

Rousay, Egilsay and Wyre Development Trust led HSO, with delivery support from Community Energy Scotland. A technology partner developed an aggregator platform to monitor signals from the distribution system operator’s (DSO’s) Active Management System to the turbine and control the demand-side management (DSM) load (264kW of hot water cylinders and storage heaters) to the benefit of the turbine. This required the DSM loads to react fast enough to be relevant to the project’s goals.

The funded project was completed in 2019 however the community will continue to fund the project as it is now starting to show live matching as a business-as-usual activity. It has already fed learnings into two multi-million-pound projects in Orkney, with implications for the rest of the UK.

Over 70 properties benefited from the project. Energy fuels across project properties saw a total drop, due to displacement or efficiency measures, of 4,700 litres of oil; 8,000kg of coal and wood; and 20.4MWh of electricity. However, the benefits went beyond being able to reduce fuel costs and increase generation, including: energy advice; increased sense of ownership of local energy; increased revenue for community projects; employment for 3 isle residents.

A key aim of HSO was to reduce fuel poverty. A rebate compensated homeowners for the additional power used in their home at a higher cost than the alternative provision of heat (oil, coal, etc). Due to its success, the rebate rate was doubled to promote further incentive.

Surf ‘n’ Turf

The Ambition

The concept behind the Surf ‘n Turf project is to enable Orkney to both make and use more electricity locally; to reduce fossil fuels imports and CO2 emissions; and to support Orkney communities and companies to herness locally sourced energy.

How?

The European Marine Energy Centre (EMEC) has invested in an electrolyser to use power from tidal turbines operating at the company’s test site off Eday to produce hydrogen by splitting water.

To build on this, Community Energy Scotland and partners created Surf ‘n’ Turf, so that power from Eday Renewable Energy’s community wind turbine can also be used to produce hydrogen using EMEC’s electrolyser.

Hydrogen can be stored, so it is shipped to Kirkwall where a hydrogen fuel cell is housed on Kirkwall Pier. The fuel cell converts the hydrogen back into electricity by mixing it with oxygen from the air. This electricity can power facilities in the Harbour area, and the ferries when docked.

Watch this three-minute video explaining what the Surf ‘n’ Turf project involves and how the technology works.

In addition, the Surf ‘n’ Turf project is building this fuel cell to marine standards, as it would be on a ship, which will create a unique UK facility to allow mariners to train in Orkney for any future hydrogen powered vessel. 

And the future?

Through Surf ’n’ Turf, Orkney is pioneering practical uses of hydrogen. Training and new opportunities with clean fuels are potentially of significance to shipping and other industries – as well as to communities that are rich in renewable energy resources, but have grid issues of their own. 

The Surf ’n’ Turf project has attracted £1.46 million in development funding from the Scottish Government’s Local Energy Challenge Fund. 

It is co-funded by the European Union Horizon 2020 programme, under the Fuel Cells and Hydrogen Joint Undertaking. 

The project is led by Community Energy Scotland, alongside partners EMEC, Orkney Island Council, Eday Renewable Energy and ITM Power. 

PITCHES

Between August 2017 and April 2019, PITCHES integrated with the pre-existing Surf ‘n’ Turf and BIG HIT projects in Orkney as a basis for assessing the market potential for renewable hydrogen systems serving remote communities, including those in sub-Saharan Africa, showing that hydrogen-based energy systems have the potential to reduce reliance on imported fuels, reduce carbon emissions, and in future as the technology develops, to reduce energy costs.

The Malawi / Southern Africa element of the PITCHES project explored the replicability of such systems to isolated, off-grid communities in Sub Saharan Africa, by testing configurations of the system, and identifying business models which best suit off-grid communities in developing countries. In the developing world, there are many remote communities with little or no grid access – the Energy Africa campaign estimates that 70% of the Sub-Saharan population is without electricity access, and 50% of businesses there view a lack of reliable power as a major barrier to business. Whilst other energy storage technologies, such as batteries, may be more suitable for the smallest communities, integrated hydrogen systems could have potential to support medium sized communities with hydrogen mini-grids, and also the potential in future to support nascent enterprises and industries through providing local transport fuel.  

In 2018 Mark Hull & Rona Mackay visited Community Energy Malawi (CEM) to work on the PITCHES project with our sister organisation. After visiting CEM’s offices in Lilongwe and meeting the staff there, they embarked on a trip around Malawi with Edgar Bayani (CEM CEO) and Chawazi Gondwe (PITCHES Development Officer) to visit some of the micro-grids in villages across Malawi.   

Watch this video for an overview of CEM’s work in Malawi.

Chikwawa and Sitolo 

In Chikwawa, South of Blantyre, they visited two projects on different scales where solar panels were charging batteries and lights which were then loaned out to businesses and households to provide power and light. In the West they called into Sitolo where CES and CEM are supporting three villages and who were soon to have their micro-grid installed. Electricity is supplied directly to the houses in this instance. 

Kasangazi and two neighbouring villages 

In the North Rona and Mark met Corled Nkosi who developed and hand built the Kasangazi Hydro and supported the creation of two further hydros in nearby villages. Over 2,000 people have benefitted from Corled’s determination and skills.  

Power from the hydro is supplied to Corled’s village on handmade poles with bare copper wires. Although rudimentary the three hydros are life-changing for local villagers, giving the school light in the evenings for pupils to study, electric bulbs in homes to replace candles and oil lamps which have health and safety risks. There is now also supply to a local garage enabling a business to grow and bring much needed economic activity to the area. 

Thank you to Community Energy Malawi for hosting our visit. In return we were able to share our knowledge and practical experience of using hydrogen in Orkney with the CEM team when they came to visit us in 2019.

The Fishermen Three

Collaborative Wind Power 

The Hoprigshiels site was developed jointly with Berwickshire Housing Association, a Registered Social Landlord, in 2017 providing homes for over a fifth of households in Berwickshire. This project also provides an annual community benefit payment of £37,500 (plus inflation) to the communities closest to the wind farm site, to be spent on whatever they identify as their priorities.

By supplying energy to the National Grid, the wind farm will create revenue for BHA of around £20 million over the next 25 years – enough to allow them to build 500 new homes over that period.  Community Energy Scotland’s £10 million share of the revenue will enable us to support communities across the country to develop and benefit from renewable energy projects and play a crucial part in building a greener energy system.  

The development and construction of the site was project-managed by Community Energy Scotland staff, and the site has been connected to the grid under an innovative Active Network Management scheme, allowing us to start generating before local transmission upgrades have been completed.  

CREEL

Canna can!

The Isle of Canna is one of the Small Isles, located off the West Coast to the south of Skye, with a population of under 20. It has no connection to the National Grid, so had previously relied on expensive diesel generators.  

The Canna Renewable Energy and Electrification project involved the construction of a new system based around wind, solar and battery storage which has drastically reduced fuel usage and running costs. Community Energy Scotland had been assisting the community with the development of this project since 2009, and we were commissioned by CREEL to take on the project management of the due diligence and construction phases. We helped secure the final grants for the build, negotiated the contracts and lease, and worked with the contractors to ensure this complex system was installed successfully before the winter storms.  

During the first year of operation, the new system generated over 138MWh of electricity, of which 93% was renewable. This resulted in a 94% reduction in diesel usage, saving 100.9 tonnes of carbon dioxide emissions. The generators ran for under 2% of the time (operating less than 3 times per month on average), compared to running 24/7 previously. The success of the project was recognised by the judges at the 2019 Scottish Green Energy Awards, where CREEL took home the 2019 Best Community Project award.  We are thrilled that the SGEA judges recognised the persistence of the community in taking forward such a complex and ambitious project in a very remote location. 

The community secured £983,005 from the Big Lottery Fund and £150,000 from the Scottish Government’s Community and Renewable Energy Scheme (CARES), delivered by Local Energy Scotland. An additional £100,000 was awarded from the SSE Highland Sustainable Development Fund, and £50,000 each from Highlands and Islands Enterprise and the National Trust for Scotland. 

“The island is exposed to the full force of Atlantic gales and we can finally start to put that to good use! As well as reducing the noise and pollution from the generators the new scheme will give us the capacity to build additional houses here, so that we can increase the number of people who can make their home on this beautiful island” 

Geraldine MacKinnon, CREEL director

We are extremely grateful to our funders: The Big Lottery Fund and their Growing Community Assets Programme; Local Energy Scotland and the Scottish Government for their CARES and Innovation and Infrastructure Fund programmes; SSE and their Highland Sustainable Development Fund; to Highlands and Islands Enterprise; and to the National Trust for Scotland, both for their financial contribution and for the lease of the network which has allowed the project to go ahead. 

Thanks should also go to the principal contractor SSE Contracting, and to their subcontractors; CHAP Ltd (civils); Wind & Sun Ltd (PV and battery/inverter systems); and SD Wind Ltd (turbine supply and installation). 

The people of Canna would also like to thank Community Energy Scotland and Jamie Adam in particular, for project managing this scheme; Jamie kept us on track though all of the complexities involved.

Community Power Orkney

CPO’s Roots

When the Orkney communities were commissioning their individual turbines they wanted to create a local community solution that would both satisfy the requirements of lenders but also ensured value and development were retained within their communities. So, collectively they came to an arrangement that allowed turbine managers on each island to operate and maintain their own installations whilst being supported by Community Energy Scotland (rather than having to employ/procure external professional resources to achieve the same thing). This arrangement continues today. 

 

As a joint endeavour, CPO won the SURF Award for Partnership Working in 2012. It has been used for formal and informal collaboration since, and also is now mirrored by a similar arrangement in the Western Isles, called Community Power Outer Hebrides (CPOH).

 

What We Do

The group meet regularly, and wherever appropriate, exchange information and knowledge and work collectively. Most recently, CES and the trading subsidiaries of five of the community groups who operate turbines (Eday Renewable Energy Ltd, Hoy Energy Ltd, REWIRED Ltd (Rousay, Egilsay & Wyre), Shapinsay Renewables, and Stronsay Renewable Energy Ltd) have been working collectively with a joint Power Purchase Agreement (PPA) contract with energy purchasers, to secure increased value from all the green energy they produce together.
