£1.3bn Swansea tidal lagoon 'too big a prize to give up'
Supporters of the proposed £1.3bn tidal lagoon in Swansea have vowed to find a way of pushing the scheme ahead without the support of the UK government.
The sticking point is the UK government is not willing to pay Tidal Lagoon Power (TLP) the fee it wants for energy but a revised offer has been made.
However TLP has claimed no talks have taken place for more than a year.
The firm added it has "repeatedly" offered to meet ministers to discuss what price the government would pay for power and claimed the last meeting between officials and ministers "was approximately 12 months ago".

- 16 months since lagoon-minister meeting
"We will not give up on this project," said Swansea council leader Rob Stewart.
"We will now focus on how the lagoon can be delivered without UK government involvement.
"There have already been discussions with Welsh Government and they have already made a significant offer of support to the project.
"We will evaluate how this support - together with a revised funding model - can deliver this project.
"Sustainable renewable Welsh energy for future generations is too big a prize to give up."
Mr Stewart added an independent report has been commissioned to look at how the lagoon can be delivered differently.
TLP had previously asked for a 90-year contract with the UK government with an average strike price of £89.90 per megawatt hour. The new nuclear power station at Hinkley Point C in Somerset was given a strike price of £92.50/MWh for 35 years.
In January 2017, a UK government-commissioned report published by former energy minister Sir Charles Hendry recommended that tidal lagoons could play "a cost-effective role in the UK's energy mix".
But the UK government has continually refused to commit to the project saying it "must be affordable".
However, with reports suggesting it is about to close with First Minister Carwyn Jones saying it would be "another kick in the teeth" for Swansea rail electrification to the city was abandoned earlier this year.

A spokesman from the Department for Business, Energy and Industrial Strategy said: "As the business secretary told MPs recently, while we have quadrupled the proportion of our electricity that comes from renewable sources since 2010, we have a responsibility to minimise the impact on consumer bills and the Swansea proposal is more than twice as expensive as the Hinkley power station.
"Any decision on the Swansea Bay tidal lagoon project will have to represent value for money for the UK taxpayer as well as the consumer."
