UK Government policy -

Future support for Tidal Energy

What does the future hold for

marine energy?

UK ambitions for tidal energy

Key challenges for the future

Engaging with the Government


3/11

Commitments

We will introduce measures to encouragemarine energy.

The Coalition: our programme for government

The UK Renewables Roadmap (July 2011)

Eight technologies identified as those with the greatest

potential to help the UK meet the 2020 target, or offer

great potential for the decades that follow.

Marine energy (wave and tidal stream) identified as one

of the eight volume delivery expected after 2020.

Ambition

The UK Renewables Roadmap (July 2011)

200-300MW (wave and tidal) deployed by 2020

Technology Innovation Needs Assessment (Aug 2012)

Deployment scenarios range from almost no marine

energy to over 20GW in the UK by 2050.

Cost of energy generated will need to reduce by 50-75%to around 100/MWh by 2025

Successfully harnessing this energy has the potential to

deliver over 75 TWh/y (which is over 10% of the UKs

forecast electricity needs in 2050)

Costs of large scale generation in 2020

6/11

Key Challenges - costs

Energy Market Reform

2017 Technology specific Contract for Difference

Now:

Income per MWh = Wholesale price + (ROC rate x ROC value)

Under CfD:

Income per MWh is fixed at point of signing contract

Government support

Key Challenges - costs

Energy Market Reform

2017 Technology specific Contract for Difference

Mid 2020s Technology neutral contract auctions

Trajectory of reducing revenue support

By 2025, tidal energy will need to be competitive with

other forms of generation < 100/MWh

Going to need continued Government support to get

there!


8/11

Engaging with Government

Is cost of energy the only thing thats important ? - NO

What are the extra advantages and disadvantages of

tidal energy Predictable (both timing and power output)

Provides UK jobs, growth, (exports?)

Small visual impacts

????

Which do the Government care about?


9/11


Valuing the extra benefits

Ministers and Government officials are generally not

specialists - need a single comparator

Need to be able to add up all the costs and benefits

Which means

Somebody has to convert all benefits into

UK economy cash values


10/11


Be realistic!!

Cross party support will only survive while tidal power

looks like a good investment. And cash is hard to come

by.

Think about what else Government can do to help

PPAs

Risk sharing

Take advantage of programmes targeting growth


11/11

Summary

Costs need to reduce rapidly 100/MWh by 2025(ish)

Strong targeted Government support will be needed.

Need to communicate tidal energys extra benefits

And value these in simple (s) terms

Think creatively about how Government can help while

public spending is tight
