The Irish economy “couldn’t function” without the “central role of Dublin Port”, Minister for Public Expenditure Paschal Donohoe has said.

Speaking at the opening of Dublin Port’s Substation as an interpretive centre and venue, Mr Donohoe said that Dublin began as a port city, and it was easy to forget this.

“We understand that better about our history than we do about our present,” he said, stating the port is “a vital piece of national infrastructure that is an artery not just to our city, but to our economy”.

The Fine Gael minister, whose constituency is Dublin Central, said this could best be appreciated when walking out to the end of the North Bull Wall and observing the shipping traffic in the bay with “the wind in your face and the salt on your lips”.

He paid tribute to Dublin Port for “opening up walls and gates”, with the refurbished Substation being a prime example of this.

Dublin Port chief executive Barry O’Connell noted that the opening was taking place on national culture night, when a plaque honouring Bindon Blood Stoney, one of the port’s most pioneering engineers, would also be unveiled.

“Today marks another significant milestone in our journey towards making Dublin Port a destination, and achieving port-city integration,” O’Connell said.

The Substation’s opening and discovery and preservation of the 18th century sea wall, which gave East Wall its name symbolises the port’s “commitment to bridging the past and present”.

During refurbishment works on site, part of the city’s original sea wall was discovered running underneath the Substation. The 18th century sea wall once served to protect the East Wall from flooding and was a catalyst for the North Lotts reclamation of centuries ago.

“As we continue our efforts to connect the port with the city, this interpretive centre becomes a vital part of Masterplan 2040, fostering a deeper connection between our maritime heritage and the community,” he said.

Dublin Port heritage director Lar Joye said the Substation marked the point where the “port meets the city”, and once played a pivotal role in the early electrification of the port complex.

One of the Substation’s first events will be an exhibition curated by the Little Museum of Dublin in November, entitled “Solidarity: the Dockers of Dublin Port”.

A tribute to the dockers was the theme of a short performance at the Substation opening by ANU actor Robbie O’Connor, based on a short extract from “The Book of Names” by Louise Lowe.

When completed, the redbrick Substation museum display would be part of a 6.2 km cycle and pedestrian route linking port, maritime and industrial heritage landmarks and views from Dublin Port estate and overlooking Dublin Bay, Joye said.

The Liffey-Tolka project recently acquired planning permission to create a “transformative public realm” along a 1.4 km dedicated cycle and pedestrian route linking the Liffey with Tolka estuary, passing the Substation en route as part of a greenway.

Attending the event at the Substation – and assisting the minister in ringing a ship’s bell before he unveiled the section of the old sea wall - were Adam Roche (9) and Everly Whelan (9) of St Joseph’s Co-Ed Primary School.

Part of Dublin’s original sea wall dating back to the late 1720s has been discovered during excavations beneath a former electricity substation at Dublin Port.

Announcing the find today (Wednesday 5 October), Dublin Port Company also revealed the discovery of dockworker artefacts including clay pipes, leather shoe parts and pottery fragments from the 19th century.

The “historic” unearthing was made during works being carried out on the former redbrick electricity substation located near the junction of East Wall Road and Alexandra Road in the grounds of Port Centre.    

“The original sea wall once enclosed the eastern and northern sides of newly reclaimed land that would become known as the North Lotts – acting as a polder,” the port company explains.

“As the port extended eastwards away from the city, the sea wall’s original purpose became obsolete, and the facing stones of the wall were removed.

“It is likely that the stones were re-used to construct the three-metre-high boundary wall that defines the port’s perimeter today, visible from East Wall Road. It is from this original sea wall that the area known as East Wall derives its name today.”   

Jim Kelleher, head of special projects with the port’s heritage and communications team, said: “We have long suspected that part of the original sea wall may have lain beneath the old redbrick substation, which itself is a protected structure.

“But it has been incredibly exciting to have those suspicions confirmed, and to see this part of the original ‘East Wall’ for the first time.” 

The port company promises that the sea wall — visible through a glass floor — and related items will on permanent display within the restored substation at Port Centre. Dublin Port has more on the story HERE.

East Wall Water Sports Club will launch two new clinker–built rowing boats next month. The hand–crafted punts were built with the support of Dublin Port Company and Dublin City Council. 

East Wall Water Sport’s was founded in 1981 provides a wide variety of water sports activities to the local community. The new rowing boats will add to their growing fleet of vessels, which promotes coastal rowing on Dublin’s north side, according to the club's Martin Whelan.

'With the help of many other volunteers from the East Wall skiff rowing club the project has finally coming to an end. It’s wonderful to see at first hand the boatbuilding skills which our Viking ancestors handed down to us, still in use today', said Whelan.

The project began in October 2015 and the two clinker built boats, are to be blessed and launched on Sat 1st Oct at 12 noon.

With the growing popularity of rowing within the club, the skiff rowing section saw the need for these new vessels. These boats will primarily be to teach younger children the skills of rowing.

The current project is just one of numerous projects completed by this partnership over recent years that keeps alive an age old tradition of wooden boat building.

To date the club has refurbished two 26 ft rowing skiffs and built currachs and naomhogs in their workshop. Dublin Port Company provided free of charge the services of their resident shipwright Patsy Whelan and his apprentice Stephen, on a weekly basis to supervise the project.

East Wall Water Sports Club through their skiff rowing section and currach section now provide great rowing experiences for all ages at a very minimal cost. The club is open to all, young and old, and a friendly atmosphere is always maintained.

Ireland's Offshore Renewable Energy

Because of Ireland's location at the Atlantic edge of the EU, it has more offshore energy potential than most other countries in Europe. The conditions are suitable for the development of the full range of current offshore renewable energy technologies.

Offshore Renewable Energy FAQs

Offshore renewable energy draws on the natural energy provided by wind, wave and tide to convert it into electricity for industry and domestic consumption.

Offshore wind is the most advanced technology, using fixed wind turbines in coastal areas, while floating wind is a developing technology more suited to deeper water. In 2018, offshore wind provided a tiny fraction of global electricity supply, but it is set to expand strongly in the coming decades into a USD 1 trillion business, according to the International Energy Agency (IEA). It says that turbines are growing in size and in power capacity, which in turn is "delivering major performance and cost improvements for offshore wind farms".

The global offshore wind market grew nearly 30% per year between 2010 and 2018, according to the IEA, due to rapid technology improvements, It calculated that about 150 new offshore wind projects are in active development around the world. Europe in particular has fostered the technology's development, led by Britain, Germany and Denmark, but China added more capacity than any other country in 2018.

A report for the Irish Wind Energy Assocation (IWEA) by the Carbon Trust – a British government-backed limited company established to accelerate Britain's move to a low carbon economy - says there are currently 14 fixed-bottom wind energy projects, four floating wind projects and one project that has yet to choose a technology at some stage of development in Irish waters. Some of these projects are aiming to build before 2030 to contribute to the 5GW target set by the Irish government, and others are expected to build after 2030. These projects have to secure planning permission, obtain a grid connection and also be successful in a competitive auction in the Renewable Electricity Support Scheme (RESS).

The electricity generated by each turbine is collected by an offshore electricity substation located within the wind farm. Seabed cables connect the offshore substation to an onshore substation on the coast. These cables transport the electricity to land from where it will be used to power homes, farms and businesses around Ireland. The offshore developer works with EirGrid, which operates the national grid, to identify how best to do this and where exactly on the grid the project should connect.

The new Marine Planning and Development Management Bill will create a new streamlined system for planning permission for activity or infrastructure in Irish waters or on the seabed, including offshore wind farms. It is due to be published before the end of 2020 and enacted in 2021.

There are a number of companies aiming to develop offshore wind energy off the Irish coast and some of the larger ones would be ESB, SSE Renewables, Energia, Statkraft and RWE.

There are a number of companies aiming to develop offshore wind energy off the Irish coast and some of the larger ones would be ESB, SSE Renewables, Energia, Statkraft and RWE. Is there scope for community involvement in offshore wind? The IWEA says that from the early stages of a project, the wind farm developer "should be engaging with the local community to inform them about the project, answer their questions and listen to their concerns". It says this provides the community with "the opportunity to work with the developer to help shape the final layout and design of the project". Listening to fishing industry concerns, and how fishermen may be affected by survey works, construction and eventual operation of a project is "of particular concern to developers", the IWEA says. It says there will also be a community benefit fund put in place for each project. It says the final details of this will be addressed in the design of the RESS (see below) for offshore wind but it has the potential to be "tens of millions of euro over the 15 years of the RESS contract". The Government is also considering the possibility that communities will be enabled to invest in offshore wind farms though there is "no clarity yet on how this would work", the IWEA says.

Based on current plans, it would amount to around 12 GW of offshore wind energy. However, the IWEA points out that is unlikely that all of the projects planned will be completed. The industry says there is even more significant potential for floating offshore wind off Ireland's west coast and the Programme for Government contains a commitment to develop a long-term plan for at least 30 GW of floating offshore wind in our deeper waters.

There are many different models of turbines. The larger a turbine, the more efficient it is in producing electricity at a good price. In choosing a turbine model the developer will be conscious of this ,but also has to be aware the impact of the turbine on the environment, marine life, biodiversity and visual impact. As a broad rule an offshore wind turbine will have a tip-height of between 165m and 215m tall. However, turbine technology is evolving at a rapid rate with larger more efficient turbines anticipated on the market in the coming years.

 

The Renewable Electricity Support Scheme is designed to support the development of renewable energy projects in Ireland. Under the scheme wind farms and solar farms compete against each other in an auction with the projects which offer power at the lowest price awarded contracts. These contracts provide them with a guaranteed price for their power for 15 years. If they obtain a better price for their electricity on the wholesale market they must return the difference to the consumer.

Yes. The first auction for offshore renewable energy projects is expected to take place in late 2021.

Cost is one difference, and technology is another. Floating wind farm technology is relatively new, but allows use of deeper water. Ireland's 50-metre contour line is the limit for traditional bottom-fixed wind farms, and it is also very close to population centres, which makes visibility of large turbines an issue - hence the attraction of floating structures Do offshore wind farms pose a navigational hazard to shipping? Inshore fishermen do have valid concerns. One of the first steps in identifying a site as a potential location for an offshore wind farm is to identify and assess the level of existing marine activity in the area and this particularly includes shipping. The National Marine Planning Framework aims to create, for the first time, a plan to balance the various kinds of offshore activity with the protection of the Irish marine environment. This is expected to be published before the end of 2020, and will set out clearly where is suitable for offshore renewable energy development and where it is not - due, for example, to shipping movements and safe navigation.

YEnvironmental organisations are concerned about the impact of turbines on bird populations, particularly migrating birds. A Danish scientific study published in 2019 found evidence that larger birds were tending to avoid turbine blades, but said it didn't have sufficient evidence for smaller birds – and cautioned that the cumulative effect of farms could still have an impact on bird movements. A full environmental impact assessment has to be carried out before a developer can apply for planning permission to develop an offshore wind farm. This would include desk-based studies as well as extensive surveys of the population and movements of birds and marine mammals, as well as fish and seabed habitats. If a potential environmental impact is identified the developer must, as part of the planning application, show how the project will be designed in such a way as to avoid the impact or to mitigate against it.

A typical 500 MW offshore wind farm would require an operations and maintenance base which would be on the nearby coast. Such a project would generally create between 80-100 fulltime jobs, according to the IWEA. There would also be a substantial increase to in-direct employment and associated socio-economic benefit to the surrounding area where the operation and maintenance hub is located.

The recent Carbon Trust report for the IWEA, entitled Harnessing our potential, identified significant skills shortages for offshore wind in Ireland across the areas of engineering financial services and logistics. The IWEA says that as Ireland is a relatively new entrant to the offshore wind market, there are "opportunities to develop and implement strategies to address the skills shortages for delivering offshore wind and for Ireland to be a net exporter of human capital and skills to the highly competitive global offshore wind supply chain". Offshore wind requires a diverse workforce with jobs in both transferable (for example from the oil and gas sector) and specialist disciplines across apprenticeships and higher education. IWEA have a training network called the Green Tech Skillnet that facilitates training and networking opportunities in the renewable energy sector.

It is expected that developing the 3.5 GW of offshore wind energy identified in the Government's Climate Action Plan would create around 2,500 jobs in construction and development and around 700 permanent operations and maintenance jobs. The Programme for Government published in 2020 has an enhanced target of 5 GW of offshore wind which would create even more employment. The industry says that in the initial stages, the development of offshore wind energy would create employment in conducting environmental surveys, community engagement and development applications for planning. As a site moves to construction, people with backgrounds in various types of engineering, marine construction and marine transport would be recruited. Once the site is up and running , a project requires a team of turbine technicians, engineers and administrators to ensure the wind farm is fully and properly maintained, as well as crew for the crew transfer vessels transporting workers from shore to the turbines.

The IEA says that today's offshore wind market "doesn't even come close to tapping the full potential – with high-quality resources available in most major markets". It estimates that offshore wind has the potential to generate more than 420 000 Terawatt hours per year (TWh/yr) worldwide – as in more than 18 times the current global electricity demand. One Terawatt is 114 megawatts, and to put it in context, Scotland it has a population a little over 5 million and requires 25 TWh/yr of electrical energy.

Not as advanced as wind, with anchoring a big challenge – given that the most effective wave energy has to be in the most energetic locations, such as the Irish west coast. Britain, Ireland and Portugal are regarded as most advanced in developing wave energy technology. The prize is significant, the industry says, as there are forecasts that varying between 4000TWh/yr to 29500TWh/yr. Europe consumes around 3000TWh/year.

The industry has two main umbrella organisations – the Irish Wind Energy Association, which represents both onshore and offshore wind, and the Marine Renewables Industry Association, which focuses on all types of renewable in the marine environment.
