Energy and Climate Action- the WDC View of the Draft National Plan

The Western Development Commission (WDC) has just made a submission to DCCAE on the Draft National Energy and Climate Plan 2012-2030 (NECP).  The development of clear energy and climate action to 2030 is essential to achieving the national goal of a low carbon economy in Ireland by 2050.  The WDC recognises that energy and climate action will bring important opportunities for our largely rural region, but at the same time it will bring challenges that we would wish to see addressed in the NECP.   The WDC made a detailed submission to the previous consultation on the draft NECP (November 2018), therefore in this submission we only addressed specific issues arising from this draft of relevance to our region and our remit.

The Draft National Energy and Climate Plan (NECP)

The NECP usefully brings together and summarises energy and climate policy.  However, much of the focus is on current policy and, while there is a recognition that it will be difficult to meet targets with the policy that is currently in place, there is little information about the additional policies or regulations which will be needed to ensure we achieve targets.

The Plan recognises that heating is a particular issue in rural areas (p4) but there is no specific commitment or policy to address the needs of rural areas either in relation heating or transport.  Nor is there a recognition that there are unique opportunities for rural areas from the low carbon economy.  We believe that specific rural focused policies could be introduced for this. This would have benefit both in terms of achievement of EU targets and in relation to the development of the rural and regional economies.

Similarly the NECP acknowledges that the dispersed population pattern results in particular challenges in terms of transportation options.  Again there is no specific commitment or policy to address the needs of rural areas.   The National Policy Framework on Alternative Fuels Infrastructure for Transport in Ireland 2017-2030 notes that it is likely that in future electricity will fuel the majority of passenger cars, commuter rail and taxis while natural gas and biofuels will play an increasingly important role for larger vehicles like HGV and buses.  While we would agree with this, we believe that services such as EV charging points and CNG fueling points must be widely available in rural areas where population is dispersed.  Without these services being available and reliable, rural dwellers could be reluctant to adopt the new technologies and it could deter visitors who might be concerned about the availability of charging/fueling points.  In the case of HGVs and buses, lack of refueling options could increase costs of delivery or services in more rural and peripheral regions.

Electricity transmission network

In relation to the development of the electricity transmission network there is no mention of the issues noted by EirGrid in the recently published Systems Needs Assessment (Nov 2018) in the West (high need for grid development), North West (high need for grid development) and Midland (moderate need for grid development).  These need to be included. A study recently commissioned by the WDC, which we blogged about here reviewed the transmission network and current planned renewable generation to identify areas of the Western Region that have transmission capacity for new renewable generation. It found that North Mayo/West Sligo and Co. Donegal have no capacity for new generation without substantial transmission investment. Sligo/Leitrim, South Mayo and West Galway has limited capacity and will require transmission investment in the future. The WDC believes that significant investment is needed in these areas, so that the current and contracted renewable generation requirements are met and that there is potential for further future connections to ensure areas of best resource can produce most.

Gas transmission network

There is a need to review the natural gas network coverage to ensure that it is future proofed to meet the needs of all key urban centres (currently large settlements such as Sligo and Letterkenny are not connected).  There is important potential for decarbonisation in the gas network, through the future use of biogas, and through the transmission of gas for CNG refueling.  There are also economic benefits for urban centres which are connected to the natural gas network.  In the context of the NECP the broader government criteria for developing the transmission network should be reviewed.  This should include information from the study of wider benefits of connecting regions to the natural gas which has been undertaken for DCCAE but which has not been published.

Electric Vehicles

We welcomed the target of 500K EVs by 2030 but to help achieve this charging investment needs to be early and widespread. This will not just benefit those living in rural areas but will be important for those for those visiting for business or pleasure.  Lack of charging points could in future become a disincentive for visitors and could further concentrate tourism and other economic activities in areas near larger urban centres.

Built environment

We agree energy efficiency is important and welcome the ambition to increase the number of homes with a BER rating of B and above.  However, the most recent BER ratings data from the CSO shows that currently only 15% of homes assessed nationally have a rating of B or above.  In the Western Region only 10% achieve this and it is as low as 7% in Roscommon.  This highlights the need to specifically address energy efficiency and home heating issues in more rural and less well-off regions.  For dwellings in the in lowest rating categories and the costs and difficulties of achieving upgrade to a B rating are most significant.

Most homes in our region use oil for heating.  There needs to be a specific effort to encourage change in rural areas which are oil dependent.  While many of the incentives are for the installation of heat pumps it should be remembered that the use of wood biomass for heating brings very significant local economic benefits.

Transport

Employment is only one factor generating trips and the National Travel Survey shows that majority of travel is associated with non-work trips.  The importance of these non-work trips and the potential for change in this demand needs to be more central to climate action planning.

Rural people are reliant on car based transport, they have little available public transport and tend to travel greater distances. Therefore clearly rural dwellers’ transport demand patterns need to be central to planning for climate action. There must be detailed consideration of transport issues for smaller settlements and rural areas.  The majority of the population will continue to live in the historical settlement pattern and spatial planning will not change that pattern significantly to 2030 or even in the longer term (to 2050). Thus the NCEP needs to focus on current spatial patterns.

In conclusion, the WDC believes that it is essential that part of the NECP should have a specific focus on issues for rural areas, and on actions to ensure that rural areas are both in a position to benefit from a move to a low carbon economy and to meet the challenges of doing so.  This will enable them to make a fair contribution national goals in relation to renewable energy and to actions to mitigate climate change.

Electricity Generation and Demand in the Western Region- A Renewable Story

The Western Region has some of the best resources for on shore wind generation in Europe, and in the future, as technology improves, for offshore renewable energy.  The draft National Energy and Climate Plan (NECP) submitted to the EU and published yesterday (19.12.18) made a number of commitments for 2030 in relation to electricity generation and use, including the following:

  • Renewables in our power system will rise from 30% to at least 55% with a broader range of technologies likely to be deployed, e.g. offshore wind, solar, biomass
  • Coal and peat will be removed from electricity generation which will almost halve the emissions from the electricity sector.
  • Penetration of electric vehicles into our transport fleet will build to around 20%.

These will all have a significant impact on how we will generate and use electricity.  It is therefore useful to understand the current pattern of generation and demand in the Region before considering options for the future.

The Western Development Commission (WDC) has recently conducted[1] a review of electricity transmission infrastructure in the Western Region. It examined current and future needs for transmission infrastructure in the Region, and considered how increased renewable electricity generation, along with new ways of using and managing electricity and new methods of improving the use of existing transmission infrastructure might impact on need for investment.  We have published a summary of its findings in WDCInsights Electricity Transmission for Renewable Generation- What’s needed in the Western Region?

In this post the focus is on current and future renewable generation connections in the Region.  Next year, when we have had the opportunity to review the draft NECP and consider the “all-of-Government” Climate Action Plan to be completed in early 2019, it will be clearer what renewable generation connections will be required further into the future, and from that, what further transmission investment will be important.

 

Electricity Generation in the Western Region

The Western Region already has a significant connected renewable generation; almost half of the generation in the Region is renewable (Figure 1).  There is 1,371MW of conventional generation. This capacity is mainly across Moneypoint coal fired power station in West Co. Clare (863MW), Tynagh gas fired power station in East Co. Galway (404MW) and Tawnaghmore oil fired peaking plant in North Co. Mayo (104MW). In 2017 these power stations generated 4,390 GWh, which was approximately 15% of the national demand in 2017.

There is 165MW of hydro generation in the WDC region. This capacity is mainly at Ardnacrusha hydro station in Co. Clare (86MW) and the Erne stations (65MW) in Co. Donegal.  On shore wind generation makes up the rest of the renewable electricity generation in the Region (the locations are discussed further below).

In the future with the ending of coal fired generation as committed to in the draft National Energy and Climate Plan, the vast majority of renewable electricity generation in the Western Region will come from onshore wind and other developing sources including solar and potentially offshore wind and marine generation.

 

Demand and Generation connections in the Western Region

There is substantially higher capacity of both renewable and conventional generation compared to demand in the region.  Renewable generation currently connected (1,343MW) produces approximately 3,750GWh of renewable electricity. Considering total peak demand of 651MW and assuming the nation-wide demand capacity factor of 65%, the total demand in region is approximately 3,700GWh.  It can be concluded that on an annual basis the Western Region is currently producing enough renewable generation to meet 100% of its own demand.   By 2020 the Region will definitely be a net provider of renewable electricity to the rest of Ireland making a significant contribution to the 2020 RES-E targets.

Figure 2 shows the levels of connected renewable generation in the region (1,343MW) and conventional generation (1,371MW) as discussed above.   Maximum demand (at peak) was estimated by MullanGrid as 651 MW with minimum demand 164MW.

By 2020 there could be approximately 1,760MW of renewable generation connected in the WDC region, 1,595MW of wind generation and 165MW of hydro generation. There is a further 1,000MW of renewable generation in the WDC region that will have contracted or been offered connections by mid-2019 (as shown in Figure 2 above) and there is 173MW of further potential on shore wind connections in the short term (as allocated under the Enduring Connection Policy Phase 1 (ECP-1)). Clearly the potential for renewable generation and the opportunities the Region provides are significant.

 

Generation and Demand at County level

It is interesting to look briefly at the patterns of generation and demand at county level in the Western Region (Figure 3).  Donegal, which has the third largest connected capacity of on shore wind generation in Ireland, is clearly significant force in the Region’s transition to renewable electricity.

It currently has 480 MW of connected renewable generation with significant hydro generation (75MW) and 405MW capacity of wind generation with a further 254MW of contracted generation.  Galway and Clare and the next most important counties for renewable generation, with Ardnacrusha making a significant contribution (86MW) in Clare, while most of Galway’s renewable generation (286MW) from wind.  These counties have high levels of contracted wind generation which will be connected in the short term.   Mayo currently has 83MW of connected wind capacity  but has 406MW of contracted generation to be connected.

In all Western Region counties currently connected renewable generation is well above the average county demand[2].  Table 1 below gives the detail of the connected, contracted and ECP-1 capacity in each county in the Western Region alongside the estimated demand in each county (although Sligo and Leitrim are considered together).

Transmission Capacity

The transmission system has been essential in enabling the Western Region to achieve these relatively high levels of renewable generation.  There has been substantial investment in the transmission network in the Region[3] the majority of which, recently, has been in upgrading the existing electricity transmission network to provide additional capacity.  However, to allow for the continued growth of renewable generation in the Region, further investment in new transmission infrastructure is required.

There is capacity in the current transmission system for more renewable generation in areas of the Western Region including large parts of Co. Roscommon, Co. Clare and Co. Galway.  However there is concern about the pace and scale of development of new transmission circuits elsewhere in the Region.  The areas of particular concern in the medium term are Co. Donegal and North Mayo.  In Donegal, by 2022, it is expected that the connected renewable generation will have exceeded the capacity of the existing transmission system.  While the planned North Connacht project[4] will provide critical infrastructure for currently connected and some of the planned renewable generation in development in North Mayo/West Sligo, it will not provide ffor further renewable generation in the area. In the medium to long term there could also be a need for new transmission circuits to Co. Sligo/Co. Leitrim. Considering the extended timelines (at least 10 years) to deliver new transmission infrastructure it is essential to take a long-term view of the generation needs and potential in these areas.

It is important that there is a three-pronged approach to developing the transmission grid in the Region:

  1. Upgrading existing transmission infrastructure;
  2. New transmission infrastructure;
  3. Implementing smart grid solutions.

Although new transmission infrastructure is the most challenging to deliver it is critical for the development of more renewable generation in the Region.  Other factors that will impact on growth of renewable generation are the planning process and the public acceptance of onshore wind generation. Recent new transmission projects have faced strong local opposition and a lack of local political support.

To achieve long term ambitious climate action increased renewable electricity generation will be essential. Therefore further investment in transmission grid with sufficient capacity for new generation connections is crucial.
