5.1 Non-Fossil Fuel Obligation Introduction
NFFO-1
  • NFFO-1 Introduced at time of privatisation, levy
    on all energy generated from fossil fuels.
  • used to subsidise the non-fossil fuels.
  • REC's expected to purchase a minimum percentage
    of their electricity from such sources.
  • original proposal seen as solely a subsidy for
    the nuclear industry as there was little
    renewable energy
  • .(but needs
    qualification)
  • changed to a separate section for Renewables and
    Nuclear,
  • Renewables section was subdivided further by
    technology type.

5.1 Non-Fossil Fuel Obligation Introduction
NFFO-1
  • The NFFO-1 (1990) required a minimum contribution
    of 102 MW from new "renewables".
  • Fixed price per MWh was paid for renewable
    energy.
  • Price paid per unit varied significantly with
    technology
  • Wind energy had the highest price at 11p per kWh
  • compared to a typical consumer price of 6 7 p
    and a generating cost from fossil fuels of around
    3 4p per kWh.
  • a substantial subsidy for wind.
  • Potential generators had to submit applications
    for the subsidy,
  • many did not receive planning permission,
  • or failed through lack of finance.
  • Subsidy was paid until 31/12/1998 limit placed
    by the EU

4
5.2 Non-Fossil Fuel Obligation NFFO-2
  • As with NFFO-1 a fixed price was paid to all
    generating capacity
  • NFFO-2 (1991) was further divided by technology
    type

The payments under NFFO-2 expired on 31/12/1998

5.3 Non-Fossil Fuel Obligation NFFO-3
Note substantial shortfall again

5.3 Non-Fossil Fuel Obligation NFFO-3
January 1995
  • Many schemes failed through planning permission
    etc.
  • DTI "size capped" schemes
  • Ensured a sensible spread between Technologies.
  • Clearance given from EU for NFFO-3 to extend
    beyond 1998,
  • (to 30th November
    2014,
  • NOTE this excludes NFF0-1 and NFFO-2 projects.
  • Unlike NFFO -1 and NFFO-2, price paid for
    renewables was NOT a fixed price.
  • Different bids for each supplier within each
    technology band
  • Lowest bids got subsidy
  • Declared intention of 627.800 MW
  • but only 292.584MW by end of 2002.

7
5.4 Non-Fossil Fuel Obligation NFFO- 4 5
  • NFFO orders 4 and 5 came into force in 1996 and
    1998
  • given subsidy for 20 years to finish in 2016 ande
    2018 respectively
  • bids significantly lower than for NFF0-3
  • Overlap with Renewables Obligation - some schemes
    still coming on line
  • Delays in inplementation even after subsidy
    available.

5.5 Non-Fossil Fuel Obligation General
Comments
  • In 1995 declaration made by Government to have
    1500MW of new renewable generation by 2000
  • by December 31st 2003, figure was only 1058.37MW
  • a total of 97.92MW under NFFO 1 2 are no longer
    operational

BUT 142 projects with a total of 626.90MW were
contracted Actual installation of Wind is only
28 of contracted figure in 1996.

15.7 Renewables Obligation
  • First Consultation - 1999
  • Second Consultation - 2000
  • Implementation on 1st April 2002
  • (one year after NETA implemented)
  • NETA favour flexible generators and had adverse
    effects on renewables until RO was implemented
  • Aim to replace NFFO and provide a long term
    mechanism to stimulate renewables
  • Initial target 10.4 renewables by 2010
  • later increased to 15.4 by 2015
  • aspiration of 20 by 2020.

17
15.7 Renewables Obligation
  • On whom should the Obligation be?
  • The Generators?
  • The National Grid Company?
  • The Distributors (e.g. EDF in this region)?
  • The Suppliers (not generators) (e.g. nPower,
    PowerGen, etc).?
  • The Consumers?

Ultimately it was decided that Suppliers should
be liable and that they would be required to
demonstrate comnpliance

5.9 Renewable Obligation Certificates -Operation
The Regulator OFGEM
Renewable Generator
SUPPLIERS
Trader and Brokers
20
5.9 Renewable Obligation Certificates -Operation
  • 12 - 18 per MWh Recycled fines
  • 1.50 per MWh Embedded benefits - less losses
  • 4.30 per MWh Climatic Change Levy
  • 31.39 per MWh Value of ROC
  • 20 - 22 per MWh Wholesale Electricity Price

Less Neta Imbalance charges 2 per MWh
Value of Renewable Generation 56- 70 per MWh
i.e. 2.5 to 3 times of normal price.
21
5.9 Renewable Obligation Certificates -Operation
Auction Prices by Non Fossil Purchasing Agency
Buy out Prices April 2002 3p per kWh April
2003 3.059p per kWh April 2004 3.129p per kWh
This are prices paid for ROCs generated under
NFFO-3, 4 ,and 5 which by themselves do not
qualify for ROCs.
22
15.10 Renewables Obligation B B
  • Banking up to 50 of certificates in any one year
  • Borrowing up to 5 of certificates in any one
    year.
  • Since Certificates available fall well short of
    demand, these have not really been an issue.

15.11 Banding
  • Some Technologies are more cost effective than
    others.
  • Government rejected idea of different level of
    banding for different technologies
  • Capital Grants available for 2 technologies

23
15.13 Renewables Obligation Amendments
  • Amendments 1st April 2004
  • Two issues were addressed
  • Co-firing
  • This involves firing power stations with both
    fossil fuel and biomass (Ironbridge Power
    Station)
  • Threshold for ROCs
  • Prior to Amendment, a minimum of 0.5 MWh had to
    be generated in each and every month.
  • One ROC was allocated for each 1MWh, but an odd
    0.5 - 1 MWh would qualify.

24
15.13 Renewables Obligation Amendment
  • Co-firing
  • Until 31/03/ 2006 all biomass co-firing qualify
    for ROCs
  • From 01/04/2006 to 31/03/2011, 75 of biomass
    must come from crops specifically grown for
    purpose
  • Co-firing not eligible for ROCs after 31/03/2011
  • i.e. agricultural wastes do NOT come into this
    category
  • Problem Not sufficient development in crops
  • Amendment
  • Until 31/03/ 2009 all biomass co-firing qualify
    for ROCs
  • From 01/04/2009 to 31/03/2010, 25 of biomass
    must come from crops specifically grown for
    purpose
  • From 01/04/2010 to 31/03/2011, 50 of biomass
    must come from crops
  • From 01/04/2011 to 31/03/2016, 75 of biomass
    must come from crops
  • Co-firing not eligible for ROCs after 31/03/2016

25
15.13 Renewables Obligation Amendment
  • Co-firing Amendment
  • To prevent abuse with most ROCs coming from
    Co-firing
  • from 01/04/2006 to 31/03/2011 a maximum of 10 of
    ROCs can be obtained by co-firing
  • from 01/04/2011 to 31/04/2016 a maximum of 5 of
    Rocs can be obtained by co-firing
  • Many species can be harvested every 3 years
  • proposals allow 3 crop cycles during eligibility
    for ROCs

26
15.13 Renewables Obligation Amendment
  • Threshold for ROCs
  • ZICER could not qualify as output in November gt
    February could not be guaranteed to exceed 0.5
    MWh
  • Amendment
  • Average over whole year to be in excess of 0.5
    MWh per month.
  • ROCs based on annual output
  • based on number of MWh (odd 0.5 MWh and above
    qualifying)
  • Available only for generators lt 50 kW peak
  • Further amendments under discussion late 2004
  • Renewables Obligation Review 2005 - 2006 terms
    of Reference Published
  • One suggestion offset CHP against Renewable
    Obligation
  • Would make target more likely to be achieved,
  • Would considerably water down renewables
