Vol. 396 No. 1

Ceisteanna—Questions. Oral Answers. - Natural Gas.

Séamus Pattison

Question:

8 Mr. Pattison asked the Minister for Energy if he will give the known reserves of natural gas available to Ireland at the end of 1989; if he will give an estimate of when all reserves will be exhausted; if he has any plans or proposals to build a gas pipeline to Britain; if so, if he will outline the reasons for such a plan; if he has applied to the European Commission for financial assistance to build such a pipeline; if so, the response which he has secured; and if he will make a statement on the matter.

Tomás MacGiolla

Question:

10 Tomás Mac Giolla asked the Minister for Energy the total estimated reserves in the newly discovered Ballycotton gas field and the existing Kinsale Head gas field, County Cork; the anticipated life expectancy of the two fields; if it is planned to extend the natural gas pipeline to other areas for domestic and industrial use; if he will publish the agreement made with Marathon in regard to the Ballycotton field and especially the basis on which royalty payments are made; and if he will make a statement on the matter.

I propose to take Questions Nos. 8 and 10 together.

Two fields, the Kinsale Head gas field and the recently discovered Ballycotton gas field, contain the known reserves of natural gas available to Ireland at the end of 1989.

The latest estimate of recoverable reserves for the Kinsale Head gas field is 1.48 trillion cubic feet (TCF).

In the case of a new gas field such as Ballycotton, until gas has been produced for some time estimates of reserves are necessarily less exact, but the reserves in the Ballycotton field are expected to be about one-twentieth of the reserves in the Kinsale Head field.

It is currently estimated that the reserves from the two fields will be exhausted by the year 2002.

With regard to the question of building a gas pipeline to Britain, as I stated in the House in reply to Question No. 45 on 7 December last, I have given priority to the examination of long-term gas supplies, either by interconnector or as liquified natural gas, so that we will be in a position to make an early decision on the matter. The Government have decided that now is the best time to tackle the extensive planning requirements that would precede a decision on a project of that size.

A team drawn from my Department and Bord Gáis have been established and a consulting engineer has been retained to assist the group. A number of meetings with British and continental interests have taken place and further contacts are planned. It is intended that we will shortly have a clearer picture of which approach is best and we will then be in a position to begin negotiations for a gas supply and to start preparations for a pipeline contract.

It is my intention that when planning for the project is sufficiently advanced, a formal application will be made for Community assistance. Discussions have already taken place with the European Commission and already there is agreement in principle for EC part-financing of the necessary feasibility studies to be undertaken in advance of final decisions on the required capital expenditure.

With regard to the "agreement" referred to in Deputy Mac Giolla's question, I assume he is referring to the gas sales agreement recently signed by Marathon Petroleum Ireland Limited and Bord Gáis Éireann. This agreement is a confidential contract between the two parties and will not, therefore, be published. Royalty payments provided for in existing agreements with Marathon will apply to the Ballycotton gas field.

With regard to the question of extending the natural gas pipeline, I would refer the Deputy to my reply to the House on 7 December last on this issue. In essence, the position is that further extensions to supply customers adjacent to the network will continue to be undertaken only where it is commercially viable to do so.

Having regard to the Minister's statement that the known reserves may be exhausted by the year 2002, would the Minister clarify the purpose of the proposed pipeline to Britain? Is it for the purpose of exporting gas or importing gas?

The existing gas supply network is dependent on a single gas pipeline coming from the gas head at Kinsale and Ballycotton to shore and on to Dublin, Dundalk and the various spurs. It is a matter of crucial importance to give an assurance to gas customers that in the event of any breakdown in the pipeline there will be an alternative source of gas supply. I consider the position of those customers to be vulnerable because of the lack of an alternative source of gas in the event of a major accident or breakdown. If a decision is not to be made in regard to a gas interconnector to allow the import of gas in the event of its being required, or the export of gas in the event of an excess of gas being available here, then we will have to face a decision in regard to building reserve tanks in Dublin or elsewhere to hold liquified natural gas for use in the event of a breakdown. It is a matter of ensuring continuity of supply to customers.

The drilling programme is continuing and there are expectations of further successes. We may strike a larger gas well which would exceed the national demand and allow us to export in the future. It is prudent to proceed with the preparation by way of design and arrangements for the construction of the pipeline as quickly as possible. It could take four or five years before such a pipeline would be in place. It is good, long-term energy planning to have a pipeline in place for the purposes I have mentioned and it is prudent to commence that work now. We will also indicate to the Commission that we are proceeding with these arrangements. They are contributing financially to the feasibility study and this project may qualify for substantial Structural Fund aid which is only available within a certain timespan.

I agree that it is absolutely essential that supplies be guaranteed to those who are availing of natural gas. Has the Minister had any costings done in regard to the alternatives, the interconnector gas pipeline or the building of storage tanks for liquified gas? Has he considered the security implications, in view of the fact that we have found it impossible to have an interconnector for electricity to the North? It has been blown up on a couple of occasions and the matter has not been pursued since. Does the Minister agree with the Minister for the Environment who has stated that he will allow the ESB to use natural gas as a fuel for their power stations? In view of the shortage of supply does he think that should be continued?

I intervene to say that time for priority questions is fast running out and I am anxious to dispose of a remaining question.

The question of whether we should have an interconnector or liquified gas storage tanks is under consideration. The costings in regard to both will be carefully evaluated before final decisions are made. These are the two options under consideration and the cost will largely determine which course of action is to be taken. I know Deputy Mac Giolla is not suggesting that a gas interconnector between England and Ireland should be the subject of the types of attack that were mentioned. This would be a sub-sea interconnection and it would be absolutely dastardly of anybody to consider interfering with it. I am very concerned that the electricity interconnection between the 26 Counties and the Six has remained disconnected since about 1975. It is a matter I am anxious to have fully considered and I arranged for it to be raised recently between ourselves and the British authorities. It is a sad reflection on the attitude of groups living on this island that they should seek to deny people living on both sides of the Border the economic benefit that would result from such an electricity interconnection. I hope that wiser counsel will prevail and that consideration can be given to the reconnection.
