What is subsidy free?

  • It is clear that as we stand many renewable technologies are being asked to

invest on a subsidy free model

  • And to meet our targets the will need to succeed
  • But what does subsidy free mean?
  • Is it no government support or consumer levy funding at any time for a

project?

  • Or, is it a neutral cost position for the government or consumer over the

whole life of a project?

  • We would argue for the latter, even if some in government , and particularly

treasury interpret it as the former in way cost controls designed

  • Later we unpack a powerful model to split the difference and deliver scale

deployment

  • But the question remains, without new government policy now, can subsidy

free actually be delivered?

Investment is falling

Renewable energy investment, UK 2005-18 ($bn) Annual investment lower than anytime this decade with recent spikes driven by “gold-rush” of subsidy closures From hereon likely to be lumpy and driven by commissioning dates of large offshore projects, and lower volumes of subsidy-free

Shaky investor attraction to the UK

Steady investment confidence under a stable regulatory environment – RO, ssFiTs, EMR white paper and prospect of change creating wobbles The repeated incursions against renewable support schemes drives lower investor attractiveness Attractiveness bounces back – thanks to talking up the investment potential in subsidy-free. But is it real!

  • Fossil fuel prices become progressively less influential, setting the marginal

price in fewer periods and renewables output grows

  • First mover advantages for deployment to capture higher near-side prices
  • Subsidised projects established as major proportion of the merit order and

remaining in situ into 2030s and holding a competitive advantage over subsidy free projects

  • Direction of market value heading closer towards delivery and flexibility.

  • Difficult to fix prices for longer than 2-3 years
  • Backwardation continues in the wholesale market

Stability through PPA floor prices?

Previous structures

  • Historically most lenders have requested a floor price, especially in Roc

PPAs

  • Less/ no requirement in FiT/ CfD
  • Hard floor
  • Some offtakers have the risk of wholesale prices dipping below now

Changing wholesale market: fewer offtakers have been willing to offer hard floors

Emerging structures

  • Floor design where the offtaker absorbs the reduction when wholesale

prices fall below the floor price and then recoups these loses when wholesale prices rise back above it

  • Currently offered floor prices are £10-20/MWh, if offered at all

Key take-aways

  • The wholesale market is currently buoyant and the utility PPA market is at

its most competitive

  • PPA fees at all-time low
  • Despite this, investments in subsidy free projects are challenging
  • Lack of stability/ certainty in forward prices – utility PPA market is not

providing this

  • Levelised costs too high for many investments for merchant only

projects

  • Network charging review adds to the uncertainty
  • CPPAs can provide some stability but there is a lack of liquidity and

contract negotiation is complex/ time consuming

  • Other subsidy free developments are very site-specific
  • Other revenue sources, “cheaper” network access, PoC schemes

  • Increased form of penalties likely

to be punitive to renewables

  • Potentially linked to Value of Lost

  • Would require further development of

Paying the penalty

Penalties All capacity providers holding an agreement must deliver sufficient electricity during a stress event to meet their

The penalty rate (on a MWh basis) is set at 1/24th of a provider’s annual capacity payments and capped at 200%

payments and 100% of its annual capacity payments.

  • Not new - traditionally 100MW in

E&W; 30MW in South Scotland; and 5-10MW in north Scotland

  • The Balancing Mechanism is not new

for wind, but solar has not participated to date

  • Create new entities that will allow

small assets connected to distribution network and demand Side response to provide flexibility

  • Solar and wind will likely still find

it tough to compete

Key take-aways

  • None of the alternative revenue streams are easily accessible for assets

that are not dispatchable

  • Experience from flexibility market makes it clear these markets are

complex and highly competitive so not clear if subsidy free has much of a role

  • Potential need for Power Purchase Agreement for subsidy free to be

flexible enough to optimise the assets in different market, but again not straightforward

  • These other forms of revenue could bring in some contracted revenues

that improve the ability to bring in debt, although likely to be time limited and minimal

Closure and impacts

FiT 31 March 2019 closure date announced by BEIS. Removal of generation tariffs and export tariffs to new sites BEIS suggest a guaranteed route to market may be developed… but only if they lower bills An already distressed supply chain could suffer a further slow down Pipeline projects may now be halted or re-assessed until after BEIS announcements Separate call for evidence

  • Continued MSC accreditation process
  • Opt out of this arrangement – but never back in
  • SIP reference price – banded pricing could incentivise

deployment of load shifting and storage

  • Supplier obligations above 250k – but SIP reference

means no levelisation

  • All output HH metered

1. FiT scheme has seen higher than expected uptake over its

  • lifetime. But the scheme has been slowly winding down since

changes in 2015 2. Scheme closure presents challenges for new developments. Price stability has been potentially removed and an already distressed supply chain needs buildable projects 3. We see the risks and complexities of merchant development, co- location and behind the meter as a barrier to development 4. BEIS’ guaranteed route to market option needs to be explored, as

  • therwise generation could stall

Over 9GWs of pent up onshore demand in the planning system awaiting support Need to build/repower 100GWs+ of low carbon capacity to meet 2050 Traditional investment model relies on de-risking volatility to ensure repayment of debt Utility and corporate PPAs unlikely to provide the “scalable” answer

Why revenue stabilization is needed?

The “zero-subsidy” red-herring

Even if computer models say LCOE trending lower than projected wholesale prices over lifetime showing positive NPV, policy support still required… At same time wholesale power market volatility is increasing And the direction of captured prices is down, regardless of commodity value Pool of investors capable of pricing volatility/merchant risk is very small and cost

  • f capital high

And lenders not interested in just total, but regular repayments – volatility matters Comparisons to baseload wholesale prices misleading – captured prices are real

Loan capital and interest is repaid bi-annually Project cash- flows also tested bi annually Needs to be both enough projected cash to repay the entire loan, and to comfortably repay fixed installments So banks will lend less, at higher costs, or not at all Hard to pin down where/when this will arise before making a loan Volatility in wholesale prices creates risks of periods in which installments can’t be made

Low risk lenders want projects to regularly reduce loan through repayment

Why stabilisation is needed?

Can PPAs provide it?

Committing to long term prices a challenge Less easy/more complex to transact Interested in scale and shape Floors not insulated against change in law Floor prices very low - £10-20/MWh – and wont support debt to make projects viable Ability to fix prices 3-5 years, but not whole term Utility Corporate PPAs And not all PPA providers will offer a floor Buyers need strong credit rating Only 400MWs to date signed up in GB (2% of PPA market)

What is a CfD “floor”?

Source: Cornwall Insight

  • When prices are

below the floor the generator is topped up

Floor protection

  • But when prices

are above the floor the generator pays back fully what has been paid out before getting value

  • After that there is

“upside”

Rebate to the consumer + Upside

Auctions and contracts

BEIS could cap floor price bids at levels they deem sufficient to drive viable projects Bidders would bid floor prices into CfD auctions under existing “pay as clear” approach The CfD contract settlement (and levy forecast) would be changed to accommodate “rebate” model

slide-80
SLIDE 80

www.cornwall-insight.com

Lower strike prices

  • Upside means

lower floors

  • Developers will

instead focus on the level of floor necessary to raise viable debt levels

No subsidy

  • Low floors will fall

under long-run wholesale power prices (c£30/Mwh)

  • Rebate model

means it is “working capital”

  • No impact under

low carbon levies

Attracts low cost of capital investors

  • Removes revenue

volatility

  • Floor acts

like the RO as guaranteed bankable revenue

Delivers scale capacity

  • Absence of

subsidy cost means no financial limit to the scale

  • f capacity that

can be supported

Benefits of CfD floor

No material changes to CfD structure

BENEFITS

  • Can be auctioned

– people just bid floors not two way SPs

  • CfD contract

changes not extensive

  • Focussing on life-time wholesale revenues versus LCOE is a fallacy
  • What matters is investor assessment of risks and what drives their

decisions

  • Volatility in prices creates challenging risks for debt providers in particular
  • Debt has been the engine of growth in renewable deployment to date,

allowing growth to be achieved at maximum scale and lowest cost

  • Stabilising price is required in a world of increasing wholesale power

volatility

  • CfD floor structure removes the risk of volatility at zero cost to the

consumer – driving the growth in low-cost capacity to meet targets
