Select Committee on Environmental Audit Minutes of Evidence


Memorandum submitted by The Combined Heat & Power Association

BACKGROUND TO THE COMBINED HEAT & POWER ASSOCIATION

  1.  The Combined Heat & Power Association (CHPA) works to promote the wider use of Combined Heat and Power (CHP) and community heating. The Association is the UK's leading advocate for high efficiency CHP technology.

  2.  The CHPA has an active role in COGEN Europe to secure effective European wide policies for CHP.

  3.  The CHPA has well over 60 members and represents a significant proportion of the total CHP capacity within the UK. Our members are made up of CHP developers (small and community scale, large scale industrial and utility companies), end users, suppliers, public sector bodies and professional services providers. In nearly all cases fiscal regulatory incentives, and in particular CCL, play a vital role in the economic viability of CHP. The CHPA hopes that the comments and suggestions made in the course of this response help the Committee in their research and informs future Policy in this area.

SUMMARY OF MEMORANDUM

  4.  CHP or cogeneration, presents an important opportunity to realise carbon dioxide savings in a range of commercial and industrial applications. These savings are archived through the generation of heat and power on-site, or local to the power use, providing the opportunity to utilise the heat that would otherwise be wasted, whilst also avoiding significant transmission and distribution losses.

  5.  The Climate Change Levy (CCL) has been a significant and important incentive for the operation of CHP plant through the Levy Exemption Certificates (LEC) scheme.

  6.  It has had a mixed impact in encouraging the wide-scale development of new CHP plant, with the real value of the CCL often proving insufficient to ensure the long-term commercial viability of new CHP investments in the UK's liberal energy markets. The value of CCL does not reflect changing energy costs, In particular the differential between fossil fuel and electricity prices, on which the commercial viability of CHP depends. The recent introduction of indexation to RPI is a help, however RPI does not reflect relative movements in fuel and power prices that impact directly on the viability of CHP plant.

  7.  It has had the greatest impact in encouraging some very large industrial projects that benefit from economies of scale and positive project circumstances and in the commercial sector, which faces higher prevailing market prices for energy.

  8.  Climate Change Agreements (CCAs) have had a negligible impact on CHP development since installation and in some sectors did not contribute towards the meeting of sectoral targets. Likewise the requirement placed upon sectors to develop CHP where it is "cost effective" led to varying definitions as to what "cost effective" meant at a time when, after the introduction of NETA, CHP economics were difficult. Additionally, where CHP plants have been installed, unrecognised potential may still exist where higher power to heat ratios are possible in addition to greater primary energy savings. CCAs have also worked to compromise benefits to CHP from CCL exemptions in providing an 80% discount on CCL liabilities for business.

  9.  Enhanced Capital Allowances (ECAs) have had very limited impact owing to the restrictions placed on accessing the benefit. Notably CHP plant developed and owned by utilities for the benefit of their customers are not eligible to receive ECAs. Furthermore the benefit of ECAs can only be realised in circumstances where the company owning the CHP plant is earning a profit and therefore eligible for relief from corporation tax.

  10.  With regards to the development of new CHP capacity, the lack of certainty over the future availability (from April 2013) and the accessible value of the CCL benefit means that in today's market the CCL is failing to act as a meaningful driver to the CHP developer. A CHP project today is likely to receive, at best, four years of cashflow benefit from CCL; a larger project somewhat less.

  11.  The lack of future certainty over the CCL will also limit the scope for continued operation of the existing CHP fleet, much of which will require significant mid-life investment over the next five years. Without CCL benefit, or a benefit of enhanced value, this fleet may be decommissioned or become a dedicated, flexible power-only plant that will be able to access higher revenues from mid-merit or peak-power markets. Running in a flexible power-only mode will compensate an operator for the loss of CCL revenues but removes the GHG benefits associated with cogeneration.

  12.  The loss of benefits associated with Good Quality Combined Heat and Power (GQCHP) are now likely to be further undermined by forthcoming changes to the assessment criteria proposed by the Government's CHP Quality Assurance (CHPQA) scheme to comply with the EU Cogeneration Directive (2004/8/EC)[1].

RESPONSE TO SPECIFIC QUESTIONS RAISED

Is it right for the Levy and Agreements to target energy use, or should they be reformed to target carbon emissions directly? If so, how should they be changed?

  13.  Carbon emissions are increasingly becoming the common currency of climate change policy. However each policy instrument should focus on the practical changes that a consumer can make to improving energy efficiency or reduce direct emissions. Customers cannot directly influence the carbon intensity of grid electricity generation.

  14.  It is of central importance that future reforms or extensions to, or replacement of, CCL is done in a way that guarantees that there is continuity in regulatory incentives, those have played a key role in building CHP capacity to date.

  15.  Adoption of carbon as the metric would help to bring greater transparency to this instrument but will highlight the fact that carbon emissions from electricity generation are already covered by the EUETS. For participants in the EUETS it would raise questions about double counting of their own non-electricity emissions.

With the advent of UK-wide carbon budgets from 2008 (proposed under the draft Climate Change Bill), how valuable is the focus of the CCL and CCA on the efficiency with which business consumes energy? Would it be better to have an instrument that enforced absolute caps in energy use (or CO2 emissions)?

  16.  The merit of absolute caps is highly dependent upon the ability of businesses to respond to this incentive.

  17.  Caps imply a tradable certificate-based system that affords businesses covered by a scheme, the flexibility to purchase allowances to meet their capped limit. Many businesses may not have the ability or inclination to actively trade in such a market, thereby restricting liquidity and any inherent benefit of the cap-and-trade model.

  18.  However, should the proposed Carbon Reduction Commitment be extended to cover sites currently under CCAs, this could be a possibility. Care must be taken to ensure that onsite generation, in particular, CHP is not disincentivised. The risks of disincentives can be presented by a range of circumstances, for instance allocation of free allowances for conventional "merchant" power generation or inappropriate assumptions over the carbon emissions associated with the output from CHP plant that does not qualify as CHP electricity.

  19.  As a rule, the calculation of emissions generated on site should be based on the fuel inputs (as with ETS) rather than as currently proposed in the CRC consultation.

How well do the Levy and Agreements fit together with other existing and proposed climate change policies, and what can be done to ensure maximum impact from complementary policies with minimum administrative burden and overlap?

  20.  As an energy levy, the CCL operates in a fundamentally different manner to the EUETS:

    —  With CCL, the levy rate or "price" is fixed, leaving the level of compliance to reach its equilibrium level, whereas.

    —  With EUETS, an attempt is made to fix the extent of abatement, leaving the cost of compliance, in the form of an allowance price, to reach its own level.

  21.  This difference in operation between the mechanisms means that they have the potential to operate in a complementary manner, each addressing the limitations of the alternative.

  22.  By way of illustration, a carbon tax variant of the CCL could establish a floor in the market price for carbon, whilst allowing the price of carbon to float above this level. This approach would provide business with the certainty of a minimum avoided cost for carbon abatement measures, which is lacking from the current matrix of incentives for capital-intensive abatement options such as CHP.

  23.  The need to fill gaps in the coverage of existing and proposed policy instruments remains prominent. Under a recently proposed policy instrument, sites that do not come under EUETS and have less than 25% of their energy emissions covered by CCAs, in addition to having a yearly half hourly metered electricity consumption of more than 6000MWh, will be subject to the Carbon Reduction Commitment scheme to commence in 2010. Until this is introduced, there will continue to be many sites which are not in EUETS and yet have a majority of their energy emissions not covered by a CCA.

What have been the economic impacts of the CCL and CCA on the organisations subject to them, and the wider UK economy?

Impact of CCL and Related Incentives on CHP

  24.  The Association is concerned that CHP as a relatively low-cost, high impact carbon abatement technology has not been strongly incentivised by the CCAs.

  25.  The following table illustrates the uptake of CHP in the CCA sectors since the introduction of the Agreements. In interpreting the data, it should be recognised that a major CHP project will typically be operationally commissioned some two to five years from project inception. Thus any impact arising from a CCA would normally only be attributable to plant entering into operation from 2004-05 onwards.

  26.  The data demonstrate that there has only been a small increase in CHP capacity that may be linked to the CCA framework. In 2002 industrial CHP electrical capacity stood at 4,089 MWe across 292 sites, whilst total CHP electrical capacity stood at 4,595 MWe on 1,509 sites[2]. Recognising the constraints of project lead times described and so disregarding the period 2002-04, the 183 MWe of capacity added in the period 2005-07 represents an increase of less than 5% in industrial CHP capacity over the 2002 figure.

  27.  The principal incentive for CHP presented by the CCL is through an exemption from the Levy for both the input fuel and that proportion of the power produced that is deemed as "Qualifying Power Output". Qualifying Power Output is determined under the Government-sponsored CHP Quality Assurance (CHPQA) framework that identifies those CHP plant that meet minimum standards for energy efficiency and primary energy savings.

  28.  Initially this benefit was restricted to the power consumed on-site, thus limiting its impact and so encouraging the development of sub-scale CHP plant matched only to the power demand of a site. In many applications the heat load of a site provides the opportunity for the development of a significantly larger CHP plant, however this situation would necessitate the export from the site of any power that is surplus to the site's requirements. In many cases, without the value derived from the CCL exemption, this scale and configuration of plant would not prove commercially viable.

  29.  The value of the incentive has been further eroded by the 80% discount from the Levy that is afforded to qualifying sites under CCAs. In this situation the incentive for CHP presented by the Levy is only 20% of that for sites outside of an Agreement. In these circumstances a site in a CCA does have the facility to export the power from its CHP plant in order to realise a greater proportion of the CCL benefit, replacing the exported power with conventional grid supply. However this arrangement introduces further complexity and contractual cost.

  30.  In any situation the benefit of the CCL exemption for exported power is subject to leakage of value through the supply chain that is needed to take the power from the CHP plant to the final consumer. Parties along the supply chain, including the final consumer, will seek to access some of the additional value created by the CCL exemption. The extent of this leakage will relate to the transaction costs, the volumes of power involved and the relative market position of the counterparties involved. In general terms the smaller a CHP plant, the greater the impact of this leakage.

  31.  The residual value of the CCL exemption to a CHP project will vary on a site-by-site basis. The theoretical maximum incentive available would be £4.41 per MWh of electricity produced. Small-scale CHP plant on a site within a CCA may see this incentive reduced to approximately £0.80 per MWh once the effect of the 80% CCA discount and a sharing of the benefit with the customer are taken into account. If the plant is required to export power to realise this benefit, then the value could be reduced further. Larger plant will tend to fare better, and such plant owned by a utility may expect to realise approximately £3.57 per MWh.

Future Risks for CHP Presented by the CCL

  32.  Looking forward, there is no guarantee from the Government over whether the CCL will be retained beyond 2013, or what the level of taxation will be. This situation presents major uncertainties for CHP plant, for which the benefits afforded by the CCL represent a significant contribution to the revenues of any investment. Any investment case will only recognise the revenues from CCL exemption until the 2013 date, thus limiting the value of that investment. The lack of clarity over the future of the CCL will have an increasingly deleterious effect on the expansion of new CHP capacity and scope for refurbishing and retaining existing capacity.

Wider Competitiveness Effects for UK Business

  33.  Incentives for CHP vary markedly between European Member States, bringing significant impacts for the competitiveness of those sectors exploiting CHP. Strong incentives in Belgium, for instance, are resulting in new investment in the energy infrastructure, and specifically CHP. The recent Cabinet announcement by the German Federal Government, augmenting existing feed-in tariff arrangements with additional investment incentives is expected to lead to a wave of investment in lower-cost and low-carbon energy supply infrastructure that will help support the competitive position of the industrial sites that benefit from this investment. [Reference Cabinet position]. Relatively weak levels of incentive for CHP in the UK, allied to the uncertainty over the continuing availability of the benefit will therefore tend to undermine the long-term competitive position of the UK industrial sector, as competing Member States' industries benefit from policies that support investment in CHP capacity and related energy infrastructure.

Should the Climate Change Agreements be reformed in any way? For instance, should the Agreements be simplified, or the sectoral targets made more stringent?

  34.  The incentivisation of CHP must be harmonised across the various sectoral Climate Change Agreements to include the installation of CHP in meeting the sectoral energy saving targets. Likewise sectoral targets should be made more stringent.

  35.  The entire pattern of incentives for the non-EUETS sector should be simplified, in order to provide clarity for the sectors affected, for businesses providing low-carbon goods and services, and for Government to better understand the impact of these incentives.

What are the main barriers to accelerating energy efficiency in the business sector? How can these be overcome?

  36.  The CHPA can only comment in respect of CHP.

  37.  CHP is a higher capital cost investment to meet energy needs compared to simple boiler plant and taking grid electricity. Therefore this will require a player to make significant capital outlay or enter into a long-term "Energy Service" type contract. These represent a liability to both business and the developer. Business needs some measure of certainty over long-term costs and benefits to enter into such commitments.

  38.  By contrast the policy derived incentives for investments are short-term and uncertain in nature, as described previously:

    —  EUETS needs a stable framework and long term targets to provide firm value beyond Spring 2013.

    —  CCL exemption on electricity exports is due to expire in Spring 2013.

    —  Qualifying conditions for new Good Quality CHP developments are now much more stringent under revisions to the CHPQA scheme imposed by transposition of the EU Cogeneration Directive. For existing schemes the revisions will come into force from the beginning of 2011 and will result in a considerable, and as-yet undefined, reduction to CCL exemption benefits.

  39.  Consequently the conditions for expansion of CHP capacity are not favourable under the pattern of incentives and prevailing market conditions within the UK.

Alongside the CCL, the Government introduced the Enhanced Capital Allowances, to further encourage firms to make energy saving investments. How well is this scheme working? How well does it fit with other existing or proposed climate change instruments?

  40.  The ECAs scheme is potentially a major driver for the expansion of CHP.

  41.  However, its impact is only limited since access to the ECA scheme is subject to a range of restrictions. These restrictions prevent a number of potential developers of major CHP schemes from accessing the benefit and so reduce the value and viability schemes and prevent them from being taken forward.

  42.  Limitations include:

    —  A requirement that the investor/developer is the end-user beneficiary of the scheme.

    —  Access to taxable group profits, in order to realise the benefits of the accelerated capital allowance.

  43.  These restrictions limit the eligibility for, or benefit from, ECAs for many CHP developers. This includes utility developers who could be a major driving force in the development of UK CHP capacity.

The Levy exempts electricity from renewables, though so far this appears to have had little impact. Should it play a greater role in incentivising the growth of renewable electricity, and, if so, how?

  44.  The CCL is a relatively minor component of the value of a renewable energy project, with the exception of energy-from-waste schemes which are ineligible for support under the Renewables Obligation (RO). For those schemes that are eligible, the economic driver presented by the RO is approximately a greater order of magnitude and therefore has tended to eclipse that presented by CCL.

  45.  Furthermore, for renewable electricity schemes using mature technology that are eligible for the RO, the constraints on expansion of capacity are primarily grid access and planning. For emerging technologies, the lack of sufficient value over the long-term to drive early-stage investment in technology development and deployment is also a constraint.

  46.  Looking forward, it is possible that this and future Governments may seek to reduce the relative benefits afforded to the certain technologies under the RO. In the recent Department for Business, Enterprise and Regulatory Reform: Consultation response for the Reform of the Renewables Obligation, the Government has proposed that future landfill gas developments and co-firing should be liable to receive only 0.25 ROCs/MWh of qualifying renewable generation. In these circumstances the benefits afforded through CCL exemption are more significant.

1   As at the date of submission, the CHPQA scheme has proposed new qualifying criteria, although these remain to be ratified. The proposed criteria will apply to existing CHP schemes from the end of 2010-Jan 2011and already apply to new schemes from Jan. 2007. In addition to meeting the existing conditions embodied in the CHPQA scheme, plant will now be required to simultaneously meet 70% energy efficiency and minimum Primary Energy Saving conditions (as set out in the Cogeneration Directive 2004/8/EC).
