Southwark Heat Network to go ‘live’ in next few months

Posted on September 24, 2013 by Admin

September 2013: Detailed interview in Inside Housing on the new SELCHP district heating project. “Southwark Council is one of the few landlords with ‘pipes in the ground’ for a new district heating system. One of the scheme’s masterminds is councillor Barrie Hargrove.” Points raised include:

  • The scheme is “looking at connecting before the winter period – October or November at the latest.”
  • The captured waste heat from SELCHP will go through a heat network to an five existing Southwark housing district heating network replacing heat produced from existing gas boilers. “It’s cheaper for the tenants and residents living in 2,500 homes as well, particularly for the council leaseholders because they’ll be paying 10 per cent less than the price of gas.”
  • The scheme “cost £7 million – Veolia have put the capital in, there’s no capital cost to the council. Council tenants and leaseholders pay Veolia for their heating bills. There will be a profit share between the council and Veolia.”

Latest review of implementation of London Plan energy policies

Posted on September 5, 2013 by Admin

September 2013: The GLA have recently produced their latest update on how the energy and climate policies in London’s spatial planning strategy – the London Plan – have helped drive forward the development of lower carbon buildings in the capital. The new 2013 report – along with previous years studies – can be downloaded here. An earlier post here provides some details on these reports.

The study ‘Energy Planning: Monitoring the implementation of London Plan energy policies in 2012‘ provides an analysis of the energy assessments relating to all finalised (stage II) planning applications determined from 1 January to 31 December 2012. As the Executive Summary of the report sets out “London planning authorities must consult the Mayor on all planning applications that are of strategic importance to London . For each planning application referable to the Mayor, an energy assessment is required setting out how the development will meet the London Plan energy policies. Following the order of the Mayor’s energy hierarchy, each energy assessment is required to set out how the development will:

  • Use less energy
  • Supply energy efficiently
  • Use renewable energy”

The analysis highlights how the London Plan’s policies are making significant headway in helping drive forward the development of more energy efficient, climate-friendly buildings in London. Some of the findings include:

  • High levels of energy demand reduction achieved with developments exceeding the requirements of Building Regulations through energy efficiency alone. The associated investment of circa £32 million will help to reduce consumers’ energy bills.
  • Circa £20 million of investment in new, high efficiency combined heat and power (CHP) plant able to produce 29MW of electricity and a similar amount of heat.
  • 74MW of cumulative CHP electrical capacity has been secured through the planning process since 2010 to the end of 2012, broadly equivalent to the capacity required to supply 150,000 homes.
  • Circa £133 million of investment in heat network infrastructure for approximately 53,000 communally heated dwellings
  • Continued investment in on-site renewable energy systems, including approximately £16 million to provide circa 87,000m2 of photovoltaic solar panels.

HNDU and Heat Networks

Posted on July 31, 2013 by Admin

July 2013: DECC’s recent publication ‘Summary evidence on District Heating Networks in the UK’ highlights that extent that London dominates the regions in relation to the use of district heating. The report sets out that “London has over half the heat networks in the UK (55%) with two thirds (65%) being small”. Table 5 from the evidence paper (copied below) provides some additional detail:

To take forward the Government’s 2012 Future of Heating Strategy, a series of actions were set out in a further report published earlier this year – The future of heating: meeting the challenge which includes a major chapter on heat networks. Not suprisingly, London is featured prominently with examples of recent activity on developing decentralised energy networks in Islington, the Upper Lea Valley, the Olympic Park and Stratford City, as well as the heat network installed in The Shard.

The report also highlights how work is being coordinated in London through the DEPDU initiative. Page 55 sets out “in September 2011 the GLA established the Decentralised Energy Project Delivery Unit (DEPDU) to support the London boroughs in bringing forward plans for decentralised energy. The unit, which is staffed by technical, financial and commercial specialists,has focused primarily on developing heat network projects.”

DECC are now seeking to replicate this model through the creation of HNDU.  The ‘meeting the challenge’ paper states that “DECC will support local authorities in developing heat networks by establishing a Heat Networks Delivery Unit (HNDU) within the Department that will work closely with individual authorities’ project teams in England and Wales. DECC will provide funding over two financial years to contribute to local authorities’ costs in carrying out early stage heat network development. This will enable local authorities to bring forward projects to the stage where they are suitable for investment including loan finance from the Green InvestmentBank or commercial lenders.” [p38]

£3m over two years will be committed to HNDU to provide specialist expertise and be a “bridge between the local authority and the market, acting as a ‘critical friend”. The unit will also have a “funding stream of £6m over two years [which] will be available to local authorities. It will contribute to the cost of procuring technical reports and advice on the phases of a heat network’s development.” [p57] The HNDU team held a workshop in  London last week where they set out their likely criteria for how they will judge applications to the fund – see the final slide (slide 12) of the following DECC presentation for full details on this. Attendees to the workshop were also informed that the HNDU team is being finalised at the moment, with an announcement expected shortly on the appointment of a lead Investment Director who will head the unit. Finance is anticipated to become available to local authorities for qualifying projects from this Autumn. Though the HNDU team has set itself a 7-year business plan – funding secured from DECC only lasts until 2015 at the moment.

Euston Road Energy Centre and District Heating Network

Posted on July 24, 2013 by Admin

July 2013: After several years building the case, it is hugely positive to see that Camden have now released a tender for a £5.7m  decentralised energy network along Euston Road. The tender document sets out that:

“The London Borough of Camden has identified a cluster of four communally heated estates in Somers Town, Kings Cross, London NW1 which are in close proximity to the Francis Crick Institute, a new major biomedical research facility due to be completed in 2015/16. The aggregated volume of heat and electrical demands for the estates and Francis Crick Institute has been assessed by Arup on behalf of the Decentralised Energy for London programme and is considered to provide an excellent opportunity for a phased decentralised energy network. Full planning consent for a centralised energy centre has been secured and full Cabinet approval has been secured from the London Borough of Camden to procure the project.”

The tender information goes on: “The scheme will be commissioned and delivered in the following phases:

  • Phase 1 – would see a heat only district heating project design, built, operated and maintained for the four estates via a district heating network connected to a central energy centre for which full planning permission has been granted.
  • Phase 2 – Once the Francis Crick Institute (“the Crick”) establishes a sufficient electrical demand (envisaged 2016) and an agreement is reached, Camden Council may commission the installation, operation and maintenance of a c.1MWe CHP unit (indicative size only) at the Phase 1 Energy Centre with a direct electrical connection to the Crick. Upon Phase 2 commission, the CHP system shall then also be the primary source of heat supply to the district heating network installed in Phase 1.
  • Phase 3 – Camden Council intends to extend the network to connect to Council regeneration planned for the wider Somers Town area over the next 4-5 years. This phase will not be procured within this exercise. However, the design and build under Phase 1 will include the expansion capacity to support future district heating demands.

The proposed heat route can be seen on the planning application for the CHP here. An open day will be held for bidders on Monday, 5 August 2013.

Bringing DSR and Planning Together?

Posted on July 1, 2013 by Admin

1 July 2013: Discussions from the latest (third) meeting of the Mayor’s High Level Electricity Working Group – which took place on 18 June –  have recently been published. The papers can be downloaded here [see details of previous meetings here]. Points of interest include:

  • GLA “officers are currently in the process of setting up a mechanism to provide UKPN regularly with up to date data from the GLA’s London Development Database in particular about planning permission.” Provision of this data will allow UKPN a better understanding of where future developments are likely to come forward, and foresight on where future energy demand – and potential future new decentralised energy generation capacity connected to the distribution network – is likely to be introduced.
  • The minutes also inform that “The GLA and UKPN have also established a sub-group with respective experts to discuss identified Decentralised Energy and demand side response [DSR] issues and develop a joint strategy initially covering UKPN’s demand site [minor typo here in minutes – this should read ‘demand side’] response initiatives and connection cost barrier for Decentralised Energy. The subgroup met on 3 May for the first time and will meet again twice this year.”
  • The minutes also capture the following interesting point: “It was also mentioned that demand side response measures work best in new developments. GLA officers confirmed that development could be encouraged to be ‘demand-side-response ready’ through the London Plan. This will be considered as part of the Further Alterations to the London Plan.” The discussions do not go on to explain how this could be done, but energy management systems on site could potentially reduce the load of a building during times of peak grid system demand (ie reduce lighting or electrical heating/cooling uses, restrict lift use) or potentially looking to onsite decentralised energy systems exporting more of their output (or conversely when there is a lot of wind or perhaps PV output on the grid, onsite DE systems such as CHP could switch off).

UK Power Networks (UKPN) – under their Low Carbon London Programme – are already undertaking trials of such demand response activities – see the following press release.

London Energy & Climate Priorities for the year

Posted on June 12, 2013 by Admin

June 2013:  The GLA’s Environment Programme budget for 2013-14 has recently been approved by the Mayor, setting out a total spend of £946,000 to support the delivery of the GLA’s environment policy and programmes. The approval form sets out in detail priorities being focussed on across the environment programme,  but listed below are those actions specifically related to energy and climate:

  • £100,000 to fund consultancy support for Energy Assessments: The London Plan sets out a requirement for developers to submit an energy assessment as part of their planning application.The Environment Team appraises at least 300 applications per year and requires part time expert consultancy support to assist on some highly technical issues. More on this  here.
  • £125,000  for the preparation of the London Energy & Greenhouse Gases Inventory (LEGGI) and London Atmospheric Emissions Inventory (LAEI) which provide baseline information on London energy use, greenhouse gas and air pollutant emissions.
  • £30,000 for a CHP in social housing study. This research will help demonstrate the commercial viability of Combined Heat and Power schemes in social housing over the installation of individual boilers and support the application of the energy hierarchy in the London Plan.
  • Guidance for developers on revised Building Regulations. The review of Part L of Buildings Regulations will lead to revised standards for new buildings coming into effect in October 2013. This study will recalibrate the standards in the London Plan (Policy 5.2 – see page 141) and provide guidance to the London Plan team and developers.
  • £30,000 to London Climate Change Partnership (LCCP) to undertake 3 projects: a) working with commercial landlords to reduce climate risks to the premises and tenants, b) working with social housing landlords in 4 boroughs to reduce overheating risks, c) undertaking a scoping study to define and increase the ‘adaptation economy’.
  • £30,000 for Hydrogen London – The Hydrogen London 2013-2014 programme will deliver the Mayor’s vision of London as a global centre of hydrogen and fuel cell activity, services and early adopter of these technologies.
  • £10,000 to review London’s CO2 emissions from waste – including to monitoring CO2 emissions from municipal waste management and reviewing CO2 metrics for waste (for previous work on this issue by the GLA see the following links here and here)
  • £160,000 to retrofitting London –  £110k will support the development of interventions with London Councils and the boroughs to remove barriers to delivery of energy efficiency. These include guidance for conservation areas and areas with a high density of listed buildings; procurement and analysis of energy performance certificate (EPC) data to enable the targeted identification of properties, quantification of the impact of emerging energy legislation and build the investment case for increasing the ‘success rate’ for delivery of measures. £50k will support the development of delivery models to maximise engagement to increase uptake in the private rented and owner occupied sectors (70 per cent of London’s housing stock).
  • £66,000 to delivering decentralised energy – Funding the London Heat Map (£16k in 2013/14 and £9k per year thereafter) – which identifies opportunities for local energy supply projects. The costs involve the GLA maintaining the current site hosted by RADE includes cost of ArcGIS server licence (a one off fee), hosting and admin costs for the site. LWaRB have agreed to pay 50 per cent towards the licence and hosting services.
  • £30,000 for Energy master plans (EMPs) – these provide the strategic planning function that underpins the delivery of strategic DE projects. The EMP provides a high-level feasibility and viability assessment and puts forward a ‘preferred solution’ for the energy infrastructure of that area. Funding will support three EMPs . EMP costs around £50k to produce. GLA will make £~10k contributions, developers and boroughs will contribute the remaining required budget. Recent energy masterplans undertaken include major regeneration sites in Croydon, Vauxhall Nine Elms Battersea, White City and London Riverside.
  • £20,000 in 2013/14 and £50,000 in 2014/15 to Licence Lite – following our recent application to become a supplier we will need to work with Ofgem and the electricity supply market to develop business model and submit for Mayoral approval. We will work with market advisors on completing matrix of services needed and completion of formal legal agreements for services. (see here and here for further detail).

Southwark Heat Services Contract Agreed

Posted on April 24, 2013 by Admin

April 2013: Southwark has recently agreed and signed a ‘Head of Terms’ agreement on a heat services contract with Veolia for “the provision of low carbon heat from the South East London Combined Heat and Power (SELCHP)”. As set out in a 2012 press release from the council, the project is to to create a district energy network which will transport heat – that is currently wasted – from Veolia’s  South East London Combined Heat and Power (SELCHP) Energy from Waste plant in Lewisham, to serve six housing estate in Southwark. Further information on the project can be seen in an earlier post here.

Following a period of consultation last year with leaseholders setting out the proposals and projected reductions in heating costs (see documents here – see the ‘Statement of Case’ document in particular to the proposed reduction in heat prices to tenants), the council has now completed negotiations with Veolia. A new Southwark report sets out some of the key requirements of the agreement. These include that:

  • The cost of heat could be no more than the cost of heating using the current gas boilers. This has been agreed.
  • There could be no capital investment required from the Council. This has been agreed.
  • The full operational risk of the system should be taken by the contractor. This has been agreed.
  • A price indexation mechanism should ensure that the cost of the heat rises less than the expected rise in energy prices. This has been agreed
  • There should be significant environmental benefits including a reduction in CO2 emissions and local pollution. This has been agreed.
  • The Council should share in the benefits of any expansion of the heat network.

The contract will expire in April 2033 at the same time as the boroughs waste PFI contract with Veolia. This project has clearly taken considerable time and effort by all concerned, but particularly Southwark officers, and they should be congratulated on seeing this project through. Getting heat output from the SELCHP plant after such a long time  (the plant is some 20 years old now)  is a considerable ‘win’ and should hopefully provide energy cost reductions to Southwark residents and broader environmental benefits in terms of carbon reduction.

Lewisham Renaissance and Decentralised Energy

Posted on April 23, 2013 by Admin

23 April 2013: The BBC’s Radio 4 World Tonight programme included an interesting 10 minute piece last night on sustainable cities with contributions from Peter Madden, CEO of Forum for the Future, and architecture critic Jonathan Glancey. Included in the discussion was mention of the Renaissance project, part of the Lewisham Gateway development. [The piece can be heard here – scroll to 20mins into the programme]

Lewisham Council’s website sets out that this major development project in the borough, recently dubbed as the Renaissance [but locally known as Loampit Vale  – opposite Lewisham station] incorporates an energy centre which contains:

“a gas powered engine  CHP (‘Combined Heat and Power’) which generates both electricity and heat, as well as a biomass boiler and gas boilers. Heat energy for residents’ heating and hot water requirements is generated within the energy centre and then distributed via an energy network to a Heat Interface Unit situated within each property, negating the need for conventional gas boilers.”

Unusually for such developments, the Renaissance scheme  will not only supply heating to the whole of the  Renaissance (including the leisure centre and also the London City Mission) but the “the energy centre will also supply electricity to the homes in the block above, as well as to the leisure centre. Excess electricity generated within the energy centre is exported to the National Grid, and the revenue generated offsets the cost of producing heat.” This is a really interesting  move – that is the sale of the electricity to onsite customers – by the developer Barratts, and needs to be studied to see how things progress. Much more on efforts being undertaken to help secure the sustainable energy credentials of this project here – and also some further detail in an early Mayoral planning report on the project [see para 99 onwards].
