This document discusses tidal lagoon power and the company Tidal Lagoon Power's plans. It notes that tidal lagoons could help address the climate challenge and UK's need to decarbonize its energy supply. Tidal Lagoon Power's proposed pathfinder project in Swansea Bay would establish the UK as a global leader in tidal lagoon technology while providing clean energy and economic benefits. The company aims to develop additional lagoon projects in the UK to contribute significantly to the country's renewable energy targets.

2. WHAT ARE WE GOING TO COVER?
• Why tidal lagoons and why now?
– Environment (post COP21)
– Energy
– Economy (post Brexit)
• Hendry Review update
• Update on TLP’s plans
• Why TLP’s approach is different
OVERVIEW

3. THE CLIMATE CHALLENGE
• Paris COP21 – need for
greater decarbonisation
commitments
• Climate change impacts and
the ‘do nothing’ scenario
• “The greatest threat to our
planet is the belief that
someone else will save it”
CLIMATE CHANGE CHALLENGES
Ambitious climate targets
80% reduction in CO2 emissions by
2050

5. ENERGY – THE SUPPLY GAP
• 2012 capacity = 100GW
• 18 major closures
• 2017 capacity = 85GW
• Spare capacity = 1.2%
• Further closures by 2030

6. ENERGY - COST COMPARABILITY
LAGOONS AS A KEY COMPONENT OF THE UK’S AFFORDABLE ENERGY MIX

7. ECONOMIC GROWTH
A NEW TIDAL LAGOON INDUSTRY
Domestic market for turbines and generators
£17bn
UK Construction jobs
71,000
GVA from construction phases
£10bn
The tidal lagoon sector can
become a key driver of industrial
growth in Wales and across the UK

BLUEPRINT APPROACH

10. HENDRY REVIEW
Key conclusions
Deliver low carbon, competitive and secure energy
Real and substantial supply chain opportunities
Establish a TPA, NPS and competition
Learning ‘pause’ before full-scale fleet
Start Swansea now as the ‘no regrets’ pathfinder

11. SWANSEA BAY: UPDATE
• The right size
• A template for future
lagoons
• The opportunity to
learn
Key 1st-of-a-kind characteristics:
Breakwater
Turbine house & sluice gates
Lagoon
Sea
THE PATHFINDER PROJECT

12. SWANSEA BAY – NEXT STEPS
• Development Consent Order – granted June 2015
• Hendry Review – published January 2017
• We still need:
• Marine Licence – NRW
• Harbour Revision Order / Boundary Review – MMO, WG
• Lease - Crown Estate
• Contract for Difference (CfD) – UK Gov
• Discharge of requirements and conditions
• Start on site – 2018
• First power - 2022
Path to starting construction
