Tidal Energy

Tidal power, often also referred to as tidal energy, is a form of hydropower that harnesses the energy found in ocean tides to produce electricity or other forms of renewable energy.

Interesting Facts

  • Tidal energy is the oldest form of renewable energy, having been used by the Romans to power water mills by when they occupied much of Britain
  • Tides are created by the gravitational effect of the moon on the earth
  • Tidal turbines are more expensive to build and maintain than traditional wind turbines, but produce significantly greater energy
  • Tidal turbines also produce energy at a more consistent rate as the tide is continuous while the wind is not always blowing
  • The world’s largest tidal turbine is produced by an Orkney based company

  • It is believed the tidal stream industry could generate £1.4billion for the UK and support 22,600 jobs by 2040
  • The UK has more installed tidal devices than any other country in the world
  • Tidal energy capacity is set to increase dramatically from 9.3 megawatts at present to 100-200MW by 2020
  • The UK’s tidal energy workforce is set to increase to around 6,000 by 2023
  • The wave and tidal market is set to be worth £800million per year to the UK economy by 2035


  • Despite the relatively good financial funding into research and development, government support to put tidal devices into commercial operation is waning
  • Tidal energy companies have struggled to compete with the more mature offshore wind industry
  • The lack of UK government support has given countries such as Canada and France the chance opportunity to close the gap

The team at AREG is committed to ensuring that businesses in Aberdeen City and Shire capitalise on opportunities in renewable energy and that our members achieve success in this rapidly growing market. Please contact us with your news, views, concerns and successes so that we are well placed to deliver on your behalf.

AREG has played an important role in the growth of Scotland’s renewable energy sector, engaging the supply chain and developing the European Offshore Wind Deployment Centre. However, we are only at the very beginning of the transition that AREG was established to both lead and support so there are still opportunities for companies to get into the constantly evolving renewables supply chain. We look forward to continuing our work together as renewables builds on its place as Scotland’s main source of power, and as we seek to deliver real change in the crucial areas of heat and transport.

Aberdeen & Grampian Chamber of Commerce has worked closely with AREG since its formation. The recent progress in the developments of offshore wind projects by Equinor and Vattenfall are as a result of the work of the group over many years. The north-east is known as the oil and gas capital of Europe. At the Chamber, we believe the region must evolve its position to being recognised as the energy capital. Whilst hydrocarbons will continue to be essential in driving our economy for years to come, the generation of renewable resources will play an increasingly important role in providing cost-effective power, innovative development and economic growth.

The enthusiasm and dedication of the early group that would become AREG was fundamental in us choosing to launch All-Energy in Aberdeen. The first tiny show was held in 2001, and AREG’s Chairman at the time, Jeremy Cresswell, played such an active role that I often describe him in terms such as All-Energy’s ‘midwife’. All-Energy is now the UK’s largest renewable and low carbon energy exhibition and conference in terms of number of attendees, space booked, and number of exhibiting companies. As AREG became firmly established, their presence and support for the event grew spectacularly over the years. We thank them most sincerely for their invaluable input.


Vattenfall has forged a strong working relationship with AREG through the development of the European Offshore Wind Deployment Centre. AREG has worked tirelessly on behalf of the North East and it can take enormous credit for the growth of sustainable energy in the region and the path it has cleared for the region to capture further investment.


Aberdeen City and Shire is emerging as a key location for renewables by successfully transferring its world-class oil and gas expertise into the sector and AREG has done much to advance this through a broad range of initiatives. It has acted as a catalyst in driving further investment in the local economy by engaging with companies, Government, public bodies and existing projects and we have been pleased to support their efforts. Scottish Enterprise will continue to engage with AREG as we increase Scotland’s use of renewable energy.
