LOT 3 - Photovoltaic Power Systems (PVPS)

LOT 4 - Industrial Energy-Related Technologies and Systems (IETS)

Please state clearly which lot you are applying for in your submission in the bid title. The application must be submitted by an organisation for a specific individual within the organisation. This can be a company, university, NGO or sole trader. An organisation may submit bids for several lots, no single individual may be proposed for more than one Lot. For example, a Supplier may bid for all four Lots; however, a different academic or employee must be nominated as the lead representative for each Lot.

Each lot will be assessed individually so please provide a separate application for each lot applied for (including declarations). Each lot will only be awarded to one bidder.

Background

The IEA works to ensure reliable, affordable and clean energy for its 32 member countries and beyond. Founded in 1974, the IEA was initially designed to help countries co-ordinate a collective response to major disruptions in the supply of oil, such as the crisis of 1973/4. While this remains a key aspect of its work, the IEA has evolved and expanded. It is at the heart of global dialogue on energy innovations.

Technology Collaboration Programmes (TCPs) are independent, international groups of experts that enable governments and industries from around the world to lead programmes and projects on a wide range of energy technologies and related issues. TCPs currently cover topics related to:

• Efficient end-use (buildings, electricity, industry, transport).

• Cleaner fossil fuels (greenhouse-gas mitigation, extraction, supply, transformation).

• Renewable energy and hydrogen (technologies and policies for deployment).

• Cross-cutting issues (modelling, technology transfer, project financing).

• Fusion power (safety, physics, materials, technologies).

The 6,000 experts in the TCPs work to advance the research, development and commercialisation of energy technologies. The scope and strategy of each TCP is in keeping with the IEA Shared Goals of energy security, environmental protection and economic growth, as well as engagement worldwide. Depending on the TCP, activities may include:

• Basic and applied research, technology development and pilot plants

• Technology assessment, feasibility studies, environmental impact studies, market analysis, policy implications

• Information exchange of research results and programmes

• Scientist exchanges

• Databases, modelling and systems analysis

• Experts’ networks.

More information on the IEA and the TCPs is available here: Technology collaboration - About - IEA.

Each TCP typically has two Delegates who represent each country at the Executive Committee: a primary Delegate and an Alternate Delegate.

Each TCP is its own entity and therefore have different methods for organising activities. The types of activities are, however, broadly consistent across the TCPs.

The UK is currently participating in 28 TCPs. The Science and Innovation for Climate and Energy (SICE) directorate in DESNZ funds 12 of these. At this time, DESNZ is looking to appoint Alternate Delegates for 4 of these TCPs to represent the UK industry alongside the primary DESNZ Delegate:

• Energy Storage - https://iea-es.org/

• Heat Pump Technologies (HPT) - http://www.heatpumpingtechnologies.org

• Photovoltaic Power Systems (PVPS) - https://iea-pvps.org/

• Industrial Energy-Related Technologies and Systems (IETS) - https://iea-industry.org/

The UK also participates in Mission Innovation, which is the leading international collaboration platform on innovation hosted by the IEA. SICE currently coordinates input into the seven Missions of Mission Innovation. Where relevant to the programme of work of the IEA Technology Collaboration Programmes, alternate delegates should seek to join up activities and stakeholder engagement.

Acronyms and terminology:

IEA TCP International Energy Agency (IEA) Technology Collaboration Programmes (TCPs): multilateral working groups established by the IEA across 8 themes (Buildings, Electricity, Industry, Transport, Renewable Energy, Fossil Energy, Fusion Power, cross-cutting)

IEA TCP Secretariat Organises the general TCP administration (requesting invoices, organising annual activities), liaises with the IEA and stakeholders

DESNZ (Primary) Delegate Government representative in the IEA TCPs. Drawn from across technical and policy teams. Primarily responsible for administration and knowledge transfer within DESNZ, quality assessment of UK outputs to IEA, but can get more involved depending on expertise and resource.

Alternate Delegate (AD) Experts in their field appointed through open competition. In charge of running the UK’s TCP activities and producing main outputs.

DESNZ TCP Co-ordinator Oversees all the TCPs at a working level within DESNZ and is responsible for the procurement of DESNZ and Alternate Delegates, reporting of TCP activities for DESNZ governing procedures and any general admin tasks not specific to individual TCPs.

National TCP Coordinator Oversees all UK TCP Activity across 28 TCP Programmes with UK representation. Facilitates engagement across TCP representatives and provides support on alignment between TCPs and policy.

Tasks / Annexes Sub-tasks produced by TCPs, where members create working groups to produce reports, gather international data on technologies/policies/ business models, etc. Known variously as tasks, sub-tasks, working groups, and annexes in different TCPs, but referred to as ‘annexes’ for clarity in this specification.

Operating agent Project manager or technical lead of an annex. In charge of defining the programme of work of the annexes, and ensuring delivery of outputs. Known under different terminology across TCPs, but used here for clarity.

National Team A team of UK experts from industry, third sector and academia convened by the Alternate Delegate.

ExCo Executive committee meeting which typically occurs twice a year (generally at least once in person).

The role of Alternate Delegate has general tasks common to all TCPs. Additional opportunities such as active participation in annex work or chairing the TCP can vary and be shaped by the AD and DESNZ Delegate. All ADs are expected to be able to complete all tasks, and the general tasks below are considered a minimum requirement. The Programme of Work will vary by TCP and will be jointly agreed with the DESNZ Delegate. The minimum requirement is expected to correspond to 12 days per financial year, amounting to a total minimum time requirement over the maximum potential duration of the contract of 29 days.

  • No preliminary market engagement: A separate pre-market engagement exercise is not considered necessary by the Department prior to launching the ITT. The IEA TCPs are long-established programmes, with clearly defined roles and responsibilities, and with already approved budgets, so a pre-market engagement would not meaningfully inform the design of the more…procurement exercise. Furthermore, they are well known within the relevant academic, research and industry communities. Given the highly specialised nature of the requirement, the ITT can be effectively promoted through established technical and professional networks to ensure broad awareness amongst potential bidders. In addition, DESNZ previously procured equivalent contracts for other TCP subject areas and signalled its intention to procure the remaining lots through a future exercise. As a result, the market has had advance notice of this opportunity for some time, with potential suppliers already expressing informal interest.

Method and what to read with care
  • Two columns, no blending. The authority column walks its own record only: notices in the 4-digit class, then the 2-digit division, then all categories (36 months, per lot, contested only), and as a last resort its 24-month row across all categories (per notice, every route). The market column is the notice’s primary delivery ITL1 × the same class, then division (36 months). Nothing is filled from the UK-wide class; an empty tile means the source published nothing usable.
  • Per lot, contested only. Find a Tender publishes bid counts per lot; a seven-lot tender is seven contests. Procedures awarded without competition (limited / direct) are excluded from bids, price pairs and decision days — they report one bid by definition. Frameworks and DPS are a separate population from contracts (6–7 bids per lot against 2–4) and only the notice’s own kind is shown.
  • Coverage. Roughly 40 % of notices publish a bid count; about half publish an ITL1 delivery location, so the market column reads the authority’s registered region when the notice has none (labelled). Award-vs-estimate pairs need a lot estimate, one active award on the lot, one canonical supplier and a gap under 60 %; about 30 % of pairs are exact matches (the buyer published the award at the estimate). n is on every figure; below 3 the tile is muted, never hidden.
  • Pounds. The expected award applies the authority’s median movement (or the region’s, when the authority has fewer than 3 pairs) to this notice’s estimate; the middle half uses the region’s quartiles. A multi-lot notice publishes an envelope, so the movement is applied per lot, never to the total. A benchmark, not a recommended price.
  • “Match” and “relevance” are model scores from the nightly matcher, not published facts. Find a Tender does not publish who is bidding. Never shown: contact details, payment behaviour, or a recommended price.
