Great British Energy Bill

Committee (5th Day)

Good afternoon, my Lords. If there is a Division in the Chamber while we are sitting, the Committee will adjourn as soon as the Division Bells are rung and resume after 10 minutes.

Amendment 111

111: After Clause 7, insert the following new Clause— “Impact assessment of offshore wind energy installations and generation(1) The Secretary of State must assess the impact on—(a) the environment, and(b) animal welfare standardsof offshore wind energy installations and generation which occur under Great British Energy’s functions.(2) If an assessment under subsection (4) determines that relevant offshore energy installation and generation—(a) is causing environmental damage, or(b) has significant animal welfare issues,then Great British Energy must cease facilitating, encouraging or participating in the relevant activity.”Member's explanatory statement This would require the Secretary of State to assess the impact on the environment and animal welfare standards of the installation and generation of offshore wind energy technologies.

My Lords, I rise to speak to Amendments 111 and 112 in my name, and in support of Amendment 113, in the name of my noble friend Lord Fuller.

Amendment 111 would require the Secretary of State to assess the impact on the environment and animal welfare standards of the installation and generation of offshore wind energy technologies. Amendment 112, also in my name, similarly requires an environmental impact assessment, but with the focus on the decommissioning of oil and gas structures.

The threat posed by the installation and generation of offshore wind farms and tidal energy is not new to the House. Many will be familiar with these concerns, as we on these Benches raised such issues in Committee in debates on the Crown Estate Bill, and discussed the purpose of electricity generation and the Crown Estate’s role in the stewardship of our seabed.

In considering the amendments in my name and that of my noble friend Lord Fuller, we must again address the Crown Estate’s strategic and unprecedented partnership with Great British Energy, which is estimated to result in up to 30 gigawatts of new offshore wind developments reaching seabed lease stage by 2030. We should expect to see considerable and accelerated growth in offshore renewable energy projects, with offshore wind contributing significantly to these efforts. The UK is the second largest offshore wind market in the world. Under the new Government, allocation round 6 has awarded 5.4 gigawatts of offshore energy contracts across fixed and floating offshore wind and tidal stream.

The speed and scale of these planned developments raises concerns about the impact on the marine ecosystem, as expressed by bodies such as Birdlife International. As stewards of our seabed and investors in and facilitators of offshore renewable energy projects, the Crown Estate and GB Energy have a duty to assess the impact of offshore energy installation and generation. GB Energy must restrict such installation and generation if it is found to cause the environment and its associated animals harm. Environmental concerns linked to the installation of offshore energy projects and the operation of these technologies include, but are not limited to, increased noise levels, the distortion in light pollution, and the potential impact on carbon storage and the biodiversity of the seabed and its composition.

My Lords, I rise to speak to my Amendment 113. I have previously tabled amendments to the Bill on land, and now I return to the sea, which well fits someone whose territorial designation is Gorleston-on-Sea in the county of Norfolk.

These amendments require the Secretary of State to assess the impact on the environment and animal welfare standards of the installation and generation of tidal energy technologies and their associated cabling. When we consider tidal energy, I am not thinking just about the fish, important though they are—in the tidal races, the machines can mash their flesh—but about sea-birds and the rest of the marine flora and fauna. I am thinking about not just living creatures but the wider environmental effects that may happen slightly away from the installations of the machines themselves, in the associated cabling that links those machines to land—a topic I will return to.

I am not against harnessing this almost inexhaustible supply of energy. The energy is there; it is year-round, predictable and reliable. It deserves to be won and it should be won. But I am not starry-eyed about the practicality of building machines that can survive in the most hostile environment, pounded by the seas and eaten away by salt-water corrosion. I am involved in the liquid fertiliser business, so I know more than most how hard it is to reliably engineer things in these tough, salt-aggressive environments. It is hard to engineer reliability in these unforgiving places, but that does not mean we should not try.

We know that tidal generation is best located where the water flows fastest—where it is choked through the channels, so that the speed naturally increases—so the machines can operate most effectively. Last November, I visited Saint-Malo and saw for myself the world’s first tidal barrage power station, opened in 1966; it is nearly 60 years old. It was a really impressive spectacle. It is cheap energy, but it has not come without cost. Thomas Adcock, an associate professor in the department of engineering science at the University of Oxford, says that there has been a “major environmental impact” on the Rance estuary as a result of the tidal station. He said that

My Lords, I rise to support my noble friend Lord Offord’s Amendments 111 and 112, to which I have added my name. It has become increasingly apparent, from many points of view, that impact assessments are necessary. In particular, in exercising its functions, GBE should be required to consider the environmental impact and the effect on sea-birds and marine life of its installation of offshore wind facilities, as well as of its decommissioning of oil and gas structures.

I also support my noble friend Lord Fuller’s Amendment 113, which seeks to place the same obligation on GBE with reference to tidal energy projects. I have looked for information on both the Sound of Islay project and the Bristol Channel project, both of which I was reasonably familiar with some years ago but about which I have heard nothing in recent years. I am heartened by my noble friend’s enthusiasm for the sector and look forward to hearing whether the Minister expects that GBE will be encouraged to make investments in it. As my noble friend Lord Fuller said, this is a slim Bill with fat consequences. We have to make sure that GBE will act in the public interest.

My Lords, I am grateful to my noble friends Lord Offord and Lord Fuller for tabling the three amendments in this group, all of which I support. I want to address a few remarks to Amendment 111.

I had not realised that we are the second-largest renewable energy market in the world. Most of the equipment is made outside the UK; I hope this is something we will do better on in future. I do not think my noble friend referred to the position of porpoises and dolphins, which have been causing me great concern over the past few years for the same reasons that my noble friend Lord Offord gave. We took evidence on this from the RSPB and from the department of ocean systems—I think it was called that—at the University of Plymouth in 2020-21.

Two issues arose from that which I would like to put to the Minister. The first, from the RSPB, said that “substantial sums” are being made, which really should be

“reinvested back into the natural environment from which”

these sums are derived. Is that something the Government are keen to do? The reason I ask is simple: I asked for a moratorium at that time, when we were under a Conservative Administration, until we had established what the impact was on birds and other marine life, such as whales, porpoises and dolphins. Over the last five years, we have had a number of inexplicable bankings of whales in particular but also of dolphins and porpoises. It is up to the industry to fund this work, so that we better understand why this is happening. If, as my noble friend Lord Offord argued, there is interference with the sonar of marine life, that should be established before we build the next stage of these massive developments at sea.

The second issue arose from Trudi Wakelin from the Marine Management Organisation. In the evidence session to us, she made the extremely appropriate point that:

“It is fair to say that there is a presumption of consent in the national policy statement at the moment, which gives a certain amount of confidence to developers as they are moving forward”.

She went on to explain that this is shrouded in confidentiality, owing to the nature of the contracts involved. I make a bid to the Minister for greater transparency in future contracts, when planning consent is sought.

I make a further plea to the Minister—I will never let an opportunity pass—that we have joined-up planning applications so that, at the same time as an offshore wind energy installation and generation planning application is sought, it is indicated that there will be onshore pylons and substations of a magnitude that would quite alarm the public. It is fair to make this transparent at the earliest possible stage, and that the planning is done as part of one application, not two separate applications—one offshore and one onshore. I know that East Anglia and Yorkshire are particularly vulnerable to these applications. With these few words, I look forward to the Minister’s response.

My Lords, I ought to report on Amendment 111 in the name of the noble Lord, Lord Offord. The assessment of the effects of offshore wind farms on the environment, with particular reference to sea-birds, has been ongoing for some years now. That does not necessarily undermine the future of the amendment, but it indicates that it might not be necessary.

The UK Centre for Ecology & Hydrology—the CEH—has been monitoring sea-birds in the North Sea since the 1970s. It largely studies birds on the Isle of May, just off the coast of Fife, but also sea-birds up and down the east coast of Britain. Over the past decade, these studies—largely funded by wind power operators, but also by the Scottish Government, the RSPB and others—have been extensively monitoring the effects of offshore wind farms on sea-birds. Admittedly, having to cope with and discount the simultaneous effect of bird flu has meant that this has proven a very complicated exercise recently but, with bird flu now on the wane, colonies of sea-birds seem to be flourishing in spite of the growth of offshore wind farms. The jury is still out, but the effect of these farms seems pretty low compared to that of bird flu and the new climate change-induced phenomenon of marine heatwaves. The latter winter current changes affect the growth and presence of sand eels, which are hugely important to the winter diet of many sea-birds.

The point is that the bottom tip of a marine turbine blade is 30 metres above sea level. That is pretty high and nearly all sea-birds fly below it. Kittiwakes are the notable exception but, even here, the CEH is helping the wind farm operators to examine how to minimise their losses. One solution is to paint one of the three blades black, which seems to have a beneficial effect. It is also helping to mitigate overall losses by building artificial nesting sites for kittiwakes on the Yorkshire cliffs, for example. The intention is that the overall kittiwake population should not be affected.

I should like first to speak to my noble friend Lord Fuller’s Amendment 113, on tidal energy. I ask the Minister what the position is on the Severn because, in theory, the Severn bore has immense capacity to generate electricity, going upstream and downstream. It always strikes me that if we are looking for tidal energy, the Severn bore offers better opportunities than almost anything else. I am told that when people looked at this, they found big problems with flooding land further upstream, which would have led to enormous compensation claims from farmers and so forth. I should be grateful if the Minister filled us in on the Government’s thinking on the Severn, because it strikes me that if we could create tidal energy there, that would be very beneficial to the country as a whole.

Amendments 111 and 112 address environmental considerations. We have seen in the newspapers today that the Government are bringing forth a Bill that will say that in future, environmental considerations will not be taken into account in quite the same way in respect of building projects. Can the Minister update us on the Government’s thinking on that Bill, when it is likely to appear and what it is likely to say? We are all interested in this issue. Will it read directly across to energy projects, as it does for construction projects? We have heard from the Prime Minister about this wonderful tunnel they have been building on the HS2 line to preserve bats, which is costing £100 million. Then, we heard that it was not going to preserve the bats after all, and they were all going to die somehow. We want to be updated on the Government’s thinking on that. We get all these remarks from the Prime Minister, but they are significant in terms of the environmental concerns associated with construction projects. What I really want to know from the Minister is whether this is going to read straight across to energy projects in the same way and make it easier to get other construction projects going, such as housing. I should be grateful if he filled us in on that when he sums up.

My Lords, I declare an interest as an adviser to a company deeply involved in the energy transition, particularly in some of the switching station construction, which, obviously, is the land-based part of the vast increase in electricity from wind pylons that is planned—necessary, in fact, for us to begin to get anywhere near the clean electricity volumes we require for the modern economy.

We all heard President Trump making some ambitious statements yesterday. He was very strong on the fact that vast investment would be required in clean electricity—indeed, electricity of all kinds, in his case—to cope with the great new data systems that he has persuaded private industry to co-operate with the state in building. I think he said it would be $500 billion, or £300 billion; whatever the figure was, it was enormous, and the amount of electricity will be colossal. Running the data centres that will be required, which we are trying to build here as well, can drain entire systems of electricity. The demand is vast. This relatively small area, worth £8.4 billion—he calls it “peanuts”, and it seems nothing compared with these figures—will be part of this, and it will obviously have a very large footprint: a major environmental impact.

My noble friend Lord Hamilton spoke about tidal power and the Thames Barrier. To give a little history—I am sorry, but it is relevant to where we are now—he will remember, because I know he has a crystal-clear memory, that, 40 years ago when he was my Parliamentary Private Secretary in the Department of Energy, the first folder on my desk on day 1 of moving into the job was a gigantic report on the Severn barrage. The conclusion was that it would not work and would have a huge environmental impact on nature and the surroundings, rather on the scale of the idea that has now been floated down at Hinkley—that some kind of marshland development should be promoted, which will also have an enormous impact and is causing a lot of protest. So, this is not a new question. We have been talking about barrages and tidal energy and its capacities, and the undoubted impact it can have in specific areas on a rather small scale, for at least 40 years, and we will no doubt be talking for the next 40 years.
