Westminster HallWestminster Hall is an alternative Chamber for MPs to hold debates, named after the adjoining Westminster Hall.
Each debate is chaired by an MP from the Panel of Chairs, rather than the Speaker or Deputy Speaker. A Government Minister will give the final speech, and no votes may be called on the debate topic.

Diolch yn fawr, Gadeirydd. I congratulate the right hon. Member for Preseli Pembrokeshire (Stephen Crabb) on securing this debate, which I hope we can use to build the cross-party consensus that we need to get moving on tidal lagoons, as well as many other much needed Welsh infrastructure projects. The Government seem to be rather caught in the headlights of Brexit.
I shall make my case for increased investment and urgency in the development of tidal lagoons in three parts. First, and most appropriately, I will outline the benefits of tidal lagoons for meeting current and future energy capacity requirements. I will then briefly touch on how they can contribute to our environmental targets, before finally outlining the economic benefits. Those Members who are familiar with energy policy will recognise my speech as an expanded response to what is known as the energy trilemma. I will conclude by highlighting the deficiencies in the Wales Bill and how it continues to hamper Wales’s ability to make use of its natural resources.
Eighteen major power stations, totalling 17,767 MW of capacity, have closed since 2012. By 2020, the amount of lost power is expected to rise to over 38,000 MW, representing more than a third of our current capacity. According to Tidal Lagoon Power, that means that, having put everything else into the mix, we will end up with a 32 GW deficit.
The 350 MW Swansea bay tidal lagoon will pave the way for projects between Cardiff and Newport, which are planned at equal capacity to Hinkley Point C. The projects will generate the lowest-cost electricity of all new power stations, and can be online in the mid-2020s. A 3,000-plus MW lagoon on the north Wales coast is planned for completion shortly afterwards, with two other projects in the pipeline for development slightly further down the line. As a fleet, the five scoped projects can generate secure, clean energy for 30% of UK homes for 120 years.
We face a clear and present risk when it comes to our long-term energy security. The highly predictable and secure energy created by tidal lagoons means that they face few of the uncertainties or dangers of other carbon-neutral technologies. A home-grown industry, producing power on our shores—what is more secure than that? What is there to like more than that?
I turn briefly to the role of tidal lagoons in meeting environmental targets, which is the second aspect of the energy trilemma. Whatever the impact of Brexit on the UK’s energy and environmental policy, under the Climate Change Act 2008, we are committed to reducing carbon emissions by 57% by 2030, on 1990 levels. As recognised by the Committee on Climate Change, it is likely that new technologies, including tidal lagoons, need to be implemented to meet that target.
In Wales, our abundant resources, particularly tidal energy, give us huge potential to become a world leader in carbon-neutral energy generation. However, Westminster is the dog in the manger when it comes to Wales’s abundant natural resources. For centuries we have been reined back from cultivating and benefiting from our own resources because of arbitrary restrictions from Westminster.
The third aspect of the trilemma is often referred to as energy equity—that is, the affordability of energy for consumers—but I shall also touch on the broader economic implications of tidal lagoons. As the first of its kind, Swansea bay tidal lagoon is undoubtedly more expensive than some of the rival technologies. However, as the project is small, its impact on household electricity bills will be small as well. For consumers, Swansea bay’s real benefits lie in its ability to act as a catalyst for an industry of cost-effective renewable energy in the form of future tidal lagoons.
That said, at a local level, during construction, Swansea alone will employ 2,323 workers, and 181 during operation. It will add around £316 million of gross value added throughout construction, and £76 million annually thereafter. We must also remember the possibilities for exporting the technology. At a time when exports are crucial to the future of the economy, why are the Government dragging their heels on the issue of getting shovels into the ground at Swansea? We can demonstrate to the world that we can lead the way on innovative technological solutions to our energy needs.
I conclude by highlighting the vicissitudes that Wales endures from Westminster. Despite Wales having a natural treasure trove of renewable resources, particularly tidal energy, Westminster refuses to let Welsh people benefit from their own environment.
Unlike under any other devolution settlement, under the current Wales Bill, there will be an arbitrary 350 MW cap on what our National Assembly can develop. That means that the lagoon in Swansea, which has already received planning permission, would have been a project decided on by Cardiff Bay, but any of the other larger projects would remain the preserve of Westminster.
My final plea to the Minister is this: allow the people of Wales to control their own natural resources, so they can make the best use—
