The Balancing act - Over capcity or under - SITA UK - EFW- Tuesday 11
1. Expected Energy from Waste

Anglo-Dutch Round table
09 October 2015
2. thinking
who says what – Defra, SITA, Eunomia, GIB, Imperial Uni
Why the debate ? – current position, assets in build and those with planning or seeking
planning – range of potential under to over, role or impact of rdf/srf in the debate
Source term changes – uncertainty over recycling performance, increase in population,
GDP influence on mix, quantity of waste
Technology mix
Lack of C&I data and this is the target ( asset by source assessments)Lack of C&I data and this is the target ( asset by source assessments)
Influence of poorly coded or illegal activities on data and capacity
Influence of the market in tuning capacity

4. UK picture - reducing landfill tonnage?
25Mtpa diverted from landfill in UK in five years
mostly through minimisation, reuse and recycling

5. Reducing landfill need
A challenge for all; SITA UK has reduced from over 60

operating landfills in early 90’s to just over 20 today.
6. Infrastructure from the past … fit for the future?

7. Increasing energy recovery from waste
UK market now more about location of facility; careful choice ofUK market now more about location of facility; careful choice of
location and transport solutions is essential for a project to be
successful.

8. Regional over capacity
Regional over capacity- possible, but not necessarily a problem,
unless you are stuck with road transport only.

9. Fuel exports
Short to medium termShort to medium term
> Bridging the gap between landfill diversion and energy recovery facilities.
R li bl d hi t ti l> Reliable and secure shipment essential.
> Reliable and secure off taker essential.
Long term
> Poor UK conditions – infrastructure built abroad.
> Good UK conditions – provide a balancing mechanism for final UK capacityp g p y
> Main capacity should be built in UK

10. UK demand balance or competition?
Likely to continue to grow through 2013-15.

12. Changing balance of revenues
Energy is becoming more important than gate fee.

18. Who wants heat?
Supply increasingly dominated by natural gas.

19. Who wants heat?
A supply increasingly less produced at home

and more vulnerable to international pressures.
20. Why heat from waste?
Benefit of combined heat and power (CHP) far better than
electricity only and provides localised source of heat for UK

electricity only and provides localised source of heat for UK
demand.
21. But heat supply is not without its challenge

Matching heat demand, balancing heat demand and/or
flexible energy delivery are key.

flexible energy delivery are key.
22. To make best use of waste heat…
Heat source must be near ‘heat sink’
> I.e near domestic users and have a mix of off-takers to
balance demand.
> Ideally more than one significant heat producer (reduced supply risk).
> Commercially reliable partners.
Finance
> Grants or incentives for grid if one does not already exist.
> Financially viable anchor customers (to help leaver further funding)- some
form of obligation to take energy (CHP sink ready!) for developments over
a certain thermal need.
> Ease of permission for ‘hard dig’ infrastructure> Ease of permission for hard dig infrastructure.

23. Not all at once!
Heat systems grow gradually and so long term stable national
and local policies and drivers need to be established.
