Because of the exceptionally dry weather, May was the first month in which we have generated no electricity at all since we started generating on 1 December 2015 . April saw only a negligible output but the wet winter and early spring resulted in our achieving 50.9% of our projected output by the end of March. With normal rainfall later in the summer and in the autumn, we still have a good chance of reaching our projected output this year.

Anafon Hydro's Second Year of Generation

At midnight on 30 November, we completed our second full year of generation. During this second year and in spite of a dry early Summer we exported

994 MWh

of clean electricity to the Grid. This represents about 3% more than our projected annual output.

Over our first two years of operation, we have exported a total of

2,130 MWh

of electricity, over 11% more than the projected amount and enough to meet the consumption of about 530 'average' UK households.

Thank you to all our shareholders and volunteers who have made this success possible!

The 2017 Ynni Anafon Energy Cyf. AGM will be held at Yr Hen Felin Community Room (LL33 0LP) in Abergwyngregyn at 12 noon on Saturday 29 July. The relevant documents will be sent to all shareholders in the near future and the Directors hope as many of you as possible will be able to attend. Refreshments will be provided and there will be an opportunity to visit the turbine house.

1 December 2016

Happy Birthday Anafon Hydro!

Midnight last night marked Anafon Hydro's first full year of generation of clean electricity. During that first year, we exported

1,128,130 KWh

of electricity to the National Grid, earning about £240,000 gross. This is 18% more than the projected annual output for the hydro of 957,000 KWh.

It is enough electricity to meet the annual consumption of 284 average homes; as there are only 100 households in Abergwyngregyn, we have effectively 'exported' almost twice the amount of electricity the village consumes.

23 October 2016

In spite of some short dry periods over the summer when there was not enough water in the river to generate power, two weeks ago the Anafon Hydro passed the milestone of 1,000 MWh generated since 1 December 2015. Output now stands at 1,028 MWh or enough electricity to power about 256 average households for a year. This exceeds the anticipated annual output of 957 MWh on which all our projections are based and there are still 5-6 weeks to go until the anniversary! Let's hope for some rain in November!

21 October 2016

Apologies for the long interval of inactivity on the YAE website. As you will see, the site has been updated and simplified. It now includes details of the Board elected at the AGM on 16 July (on the 'The Venture' and 'Y Fenter' pages) as well as a comprehensive photographic record of the construction of the Anafon Hydro in 2015 (on the 'The Project' and 'Y Cynllun' pages).

In spite of some short intervals over the summer when there has been insufficient water to generate power, the Anafon Hydro exceeded the milestone of 1,000 MWh generated two weeks ago and, today, our total output stands at 1,027 MWh in 10 months and 3 weeks of generation. This compares with the anticipated annual output of 957 MWh on which all our projections have been based. And we still have more than 6 weeks to go before the anniversary of the start of generation on 1 December.

The plant has just undergone its first annual service and is functioning as it should. One problem during the first year has been the destruction of the water level sensors at the weir by lightening strikes during thunderstorms - replacing these costs almost £1,000. However, during the service, the earthing arrangements at the weir have been improved significantly which we hope will remedy the problem.

Exceptionally heavy rainfall last winter resulted in some damage to the reinstatement around the weir and on the pipeline route. We have replaced much of the earth washed out around the weir with small stones which should prove less susceptible to future flooding and, at the request of NRW ecologists, we have reseeded and erected temporary fencing around the upper section of the pipeline route. The vegetation here is now recovering well and it may be possible to remove the fences next year, two years earlier than scheduled.

25 March 2016

After less than 4 months, we have already exported more than 565 MWh of green electricity to the grid. This represents 58% of our projected annual output!

We are very pleased to let you know of two other community hydro projects in North Wales, Ynni Ogwen in Bethesda and Ynni Padarn in Llanberis.
These provide new opportunities to invest in green energy projects similar to our own. For details of their share offers, visit and

2 January 2016 First month's electricity export to the grid

In our first month of generation (1 - 31 December 2015), we exported 171.78 MWh of electricity to the grid, worth approximately £36,000. This represents 17% of our projected annual output so all the rain we have had has had at least one positive outcome!

9 April 2015 - Charity Bank Loan confirmed!

On 8 April, Charity Bank's Credit Committee confirmed approval of their full commitment to offer Ynni Anafon Energy Cyf. a loan. The financial package needed to build the Anafon Hydro is now in place and we plan to commence construction in early May.

2 April 2015

The total amount invested in Ynni Anafon Energy Cyf. to finance the Anafon Hydro Project has now been confirmed as £450,900, £150,900 more than our target

31 March 2015 - YAE chooses contractors to build the Anafon Hydro Project

Following the tendering process, the Board will be awarding the contracts to build the Anafon Hydro to two contractors. Gelli Civil Engineering, Tremadog, will build the weir and turbine house and Kevin Williams Earthworks, Bontddu near Dolgellau, will install the pipeline.

Gelli Civil Engineering have wide experience of civil engineering work near and in rivers and Kevin Williams installed the pipeline for the Harnog Hydro and so is experienced in pipeline installation and reinstatement work in sensitive environments.

Both contractors expect to start work in early May.

27 March 2015 - John Howarth leaves the Ynni Anafon Energy Cyf. Board

As we are now about to start building the Anafon Hydro, the Board and John Howarth have decided that it would be appropriate for him to leave the Board of YAE to resume his role as Technical Consultant to the Board and Engineer for the Anafon Hydro Project.

Work on site starts!

Preparatory work on the building of the Anafon hydro will start on the 3rd March 2015.

This will entail felling of a number of conifers in the Aber Forest so as to create a working corridor for the pipeline route. The work will take approximately 3 weeks.

Final closure of the Ynni Anafon Energy Share Offer - 6 March 2015

Your last chance to invest in Ynni Anafon Energy Cyf and be part of the Anafon Hydro Project, currently the only share offer for a community hydroelectric project open in Wales.

The sale of shares reached £405,850 on 28 January. Our thanks to our shareholders for investing in the Anafon Hydro - we're ready to welcome more!

However, the Ynni Anafon Share Offer must close finally on Friday 6 March 2015 – see the Investment page of this website.

Continuing investment in Ynni Anafon Energy Cyf.

The opening share offer raised over £325,000 before the closing date of 30 November 2014. The significance of this date was that we had set ourselves a target of £300,000 to be raised by then before we could commit to building the Anafon Hydro. As you can see, we have surpassed this target and so are proceeding with the project.

However, we are still inviting investment. Every additional pound raised from shares reduces the amount we have to borrow from a bank or other lender in the form of more expensive loans. We shall continue to accept further investment until we have completed our negotiations with our primary lender. After that date, which we expect to be early in the New Year, further potential investors will be placed on a waiting list until shares become available following sales back to the company.

All further investment will attract the same EIS tax relief of 30% and interest at 5%.

Our 100th shareholder!

Today, 12 November 2014, we welcome our 100th shareholder.

Great news received today! Ofgem have granted Ynni Anafon Energy Cyf. preliminary accreditation for the Anafon Hydro project at the rate of 15.59p/KW, the rate anticipated in our financial planning. When our lease from Natural Resources Wales is signed - terms have been agreed - we shall have all the necessary permissions, leases and licences in place to proceed with the project.


When it came to launching the issue of shares in their £1.25 million community hydro scheme, the 230 villagers of Abergwyngregyn decided to do it with a flourish. They engaged the services of Sid Madge from Mad Hen to teach them about branding, marketing and finding innovative ways of reaching out to potential share holders. Jacqui Bugden, one of the volunteer directors of the scheme, says, “What we enjoyed about working with Sid Madge was that he gave us a professional face but he made sure it was still our face, still our village, still our hydro. And he taught us how to present ourselves to the world.”

The annual village fête grew into a festival of music, crafts and activities that attracted an estimated 1,000 visitors to this beautiful valley in one day. Farmers and local residents gave up their fields for the marquees, for parking and for the duck race. Villagers gave hours of their time for weeks beforehand and on the day. Local businesses and suppliers provided stands, prizes, activities and donations.

Adele Thackray, Event Manager for the day, said, “From my perspective as an event organiser the whole village pulled together as a team on the day which was fantastic to see. The event management plan was a success and everything - the great work that went into making the bunting, the organisation of the village fete, the car park management and the staffing of the shares marquee was brilliantly done.” Ian Crystal, in charge of crowd management, said, “Every week we welcome hundreds of visitors to see our waterfall. To have 1,000 of them in one day was a challenge but my team of stewards saw what was needed to keep the event flowing and just went off and did it.”

The organisation of the event was praised by North Wales Police, who said, “It's a credit to you and your stewards. The day was well-organised and there was a wide array of activities which was great to see for such a small village. The day was successful for us too. We were able to provide crime prevention advice to the masses while engaging with the younger generation and allowing them to view our kit, let off the police car siren and switch on the blue lights!”

Natural Resources Wales, Ogwen Valley Mountain Rescue, Air Ambulance, National Trust, St John’s Ambulance, all found the day a way to showcase the services they offer. North Wales Wildlife Trust said, “The day was certainly a huge success. We spoke to lots of people, plenty of children did the quiz, colouring and had a go at the tombola. And we recruited new members, all very satisfactory! Keep us informed for dates for next year.”

Conwy Land Rover played a pivotal role, providing three 4 x 4s with drivers for the day to run off-road trips up into the mountains to the intake site of the new hydro. Jason Ashley of Conwy Land Rover said, “Our team really enjoyed the day! It gave us the opportunity to showcase the capability of our cars, something we don't get to do often enough. It has been fantastic for us to work with such an exciting community project and, yes, we would be delighted to return next year.”

Land Rover also sponsored the main marquee where local musicians performed for 7 hours, the music ranging from folk and rock to classical - there was even medieval music from a medieval encampment on the field. The Penrhyn Male Voice Choir opened the the afternoon's concert. Hywel Thomas, a director of the hydro and a member of Cor Penrhyn said, “It was moving to be singing in a field in the middle of my own village, knowing it was all helping our plans for our community hydro.”

Iolo Williams, the well-known television presenter of many nature series including BBCs Springwatch and Iolo's Great Welsh Parks, formally launched the share issue and spent the day engaging with everything that was going on. He even jumped into the Aber River to help catch escaping ducks in the duck race! However, his greatest challenge was judging the exhibits at the village fête, as he said, a daunting task!

Gavin Gatehouse, chair of Ynni Anafon Energy which is building the hydro, said, “Aber Dabba Doo has announced the arrival of Ynni Anafon Energy Cyf., on the community hydro scene. Many of our visitors on the day came to the Share Issue tent to find out more about us, the largest UK community-owned hydro project outside Scotland. Within 10 days of the launch, £100,000 has already been received in share applications.”
