Lancashire tidal energy project progresses:
http://www.greenintelligence.org.uk/article/lancashire-tidal-energy-project-progresses

Plans to build an estuary-based tidal energy power station on the River Wyre in Lancashire are continuing to progress, with the developers calling it “the most affordable project of its kind”. The project, managed by Natural Energy Wyre, will generate electricity by harnessing the power of the tidal range at the mouth of the River Wyre at Fleetwood. The plant would produce large amounts of electricity four times a day with each tidal movement for at least 125 years, making it much more reliable and potentially cheaper in the long run than other renewable energy solutions such as wind and solar. The concept has already been used in other parts of the world, including Brazil, France, South Korea and Russia, and is well suited to the UK.

Suitability
The UK has some of highest tidal ranges in the world, with the River Wyre estuary experiencing ranges of more than 10 metres on spring tides. Natural Energy Wyre estimates that the 120MW plant would cost less than £300 million to build and produce enough energy to power over 50,000 homes. The proposal first gained momentum in 2015 after being given the green light by the landowner, the Duchy of Lancaster.

‘Major step’
It is not without opposition, with the RSPB arguing that it could impact wildlife on the estuary. However, Natural Energy Wyre says it will ensure the environment remains unchanged in relation to grazing birds and fish life, and will also ensure that the river remains open to leisure and commercial traffic. The plant could also be used to protect against flooding upstream. Bob Long, managing director at Natural Energy Wyre, said the project would be a much-needed commercial and employment boost for Fleetwood. “We have involved the local public in this project from the start, and constructing a tidal hydro energy plant at the chosen location would be a major step for this small town”, he said. An online poll designed to evaluate local support on the company’s website has returned a positive figure of 93 per cent in favour of the project.

Competition
If it goes ahead it could be the UK’s first tidal hydro energy plant, but it has competition from the much larger 320MW Swansea Bay Tidal Lagoon project, which would cost over £1 billion. Bob Long added: “We think it’s the most affordable project of its kind, especially compared with Swansea Tidal Lagoon.” Natural Energy Wyre is now seeking to secure subsidises through the government’s Contracts for Difference (CfD) scheme, which guarantees power purchase prices for 15 years for large generators offering the cheapest renewable electricity. The next CfD auction is expected later in 2016.

It sounds a good idea, so therefore probably wont be built.
I predict a few years of studies and consultations, and that the result of these studies will be to call for more studies.
Any change of government would lead to "re-visiting" the idea and even more studies and consultations.

I have moved a couple of posts about hydro power for a hotel to the "other alternatives" forum.
They may be found thus

I'm not sure this is great news... that same £1.3bn could cut demand by a lot more than this project will increase supply. Or the same money could generate more low carbon supply by investing it in wind, solar, or even nuclear...

I remain to be convinced this is a project that should receive lots of public (non-progressive via bills) money.

But if you're going to put money into generation, I'd rather this than nuclear! Much longer lived and easier to maintain...

We ought to be doing both really, efficiency drive alongside tidal power.

We need a range of generation methods, Chris, to help iron out fluctuations in supply. The Swansea Bay scheme is seen as a proving scheme and forerunner for the viability of tidal lagoon schemes so it is a good thing that it is going ahead in my opinion.

I'm not totally down the idea, just have mixed views. Reservations.

+1
I'd rather this than nuclear, biomass, gas, onshore wind, coal......
Yes, we also need improve efficiency, but unfortunately I can't see HMG giving £1.3 billion for insulation and the like.....
This gives the Politicians a 'willy waving' project to open....

This is what we should be working on.

For example the Government did recently run an Energy Demand Reduction pilot, where they auctioned off £4.72 million to whoever could cut the most demand for the least investment: https://www.gov.uk/guidance/electricity-demand-reduction-pilot

Over the whole scheme, they managed to cut peak demand at the cost of £203/kW. Which is WAY cheaper than building new supply.

This was only a pilot but there's no reason in principle why £1.3 billion couldn't be auctioned in a similar way, cutting peak demand by several GW compared with this project's 320MW.

£1.3bn in insulation investment will end up as half invested in insulation and half lining the pockets of companies ripping off the government by overcharging.

I said 'unfortunately' demand reduction is unlikely to get significant financial support.
One of the reasons for this has been highlighted by Cubes....
Most Government 'Green' Schemes seem to run into problems - for example - Green Deal....
and the 'Cash for Ash' scandal in NI with their Renewable Heat Incentive scheme which is set to cost £490 million......

So half of £1.3 billion ends up in the pockets of insulation companies! Is that any worse than all of £360 billion QE ending up in the pockets of *ankers? At least ordinary people would end up with well insulated houses. All they have seen from the £360 billion is an increase in house prices and rentals, which puts even more money into the sticky mitts of *ankers, and a bubble in the stock market.

One of the big advantages of a lot of smaller tidal lagoons is that the timing of high tide varies around the country so that the peaks and troughs in the power supplied from the various lagoons can cover for each other to a great extent. Yes we would need to have a greater maximum supply than would be necessary from nuclear but the safety and other advantages of tidal over nuclear make up for this many times over. With a sustainable form of storage developed this excess capacity could cover for the vagaries of wjnd and solar generation.
