My Lords, during our scrutiny we have come to know this Bill as the “decarbonisation Bill” as it has passed through this House. It has been referred to in that way by a number of noble Lords and it is a reasonable description. The Bill represents a significant intervention in the electricity market that is justified on the basis that it will help to decarbonise our electricity system. Noble Lords will be aware that we have had lengthy discussions about the setting of a decarbonisation target in the Bill in order to give that clarity of purpose and to create a responsibility on the Government to deliver through the powers that they are taking. Unfortunately, we were unsuccessful in bringing forward the setting of a date for the setting of such a target. However, on Report the Minister was kind enough to give a partial concession in relation to the Government’s commitment to monitoring carbon intensity and to acting if carbon intensity remained high. The concession was that, should carbon intensity rise year on year for three consecutive years, the Government would report to Parliament, setting out why this was the case and the additional actions that would be taken to counteract that increase.
The concession is welcome. It is not a replacement for a carbon intensity target by any means, partly because carbon intensity is currently at an astonishingly high level. This is because the merit order currently favours inefficient old coal plant over more efficient, cleaner gas stations. Therefore, currently carbon intensity is higher than would otherwise be the case. Intensity seems unlikely to increase. If it did, something would be seriously awry with government policy. The concession, while welcome, does not go far enough but I should hate to lose it. The purpose of this amendment is to place that commitment in the Bill to introduce into it a measurement of progress and a mechanism through which the Government will report back to the House on that progress and take corrective action.
It is fair to say that the interventions in this Bill and the powers that are given to the Secretary of State are so extensive that they ought to be matched with responsibility and a system of holding the Government to account to see that they are delivering. The measure of progress should be carbon intensity, the issue the Bill seeks to address. Therefore, I hope the Minister will accept this amendment in the spirit of enhancing that important part of the Bill that justifies why it has been introduced and the powers that have been taken. I beg to move.
