Assessing the risks

An easy-to-follow guide for identifying, assessing, and mitigating the risks associated with a future green space heat pump project.

What is a Risk Register?

A Risk Register is one of the basic elements included in any feasibility assessment for a project. A Risk Register identifies the risks anticipated ahead of a project start, their potential impact, and describes appropriate mitigating actions to reduce the likelihood of those risks occurring.

A Risk Register comprises four key stages:

  1. Identifying and describing the risks relevant to each task of the project.

  2. Evaluating the probability and impact of that risk if it were to occur.

  3. Explaining what actions are available and required for effective mitigation and treatment of that risk, or for managing the risk if no mitigation is possible.

  4. Re-evaluating the severity of that risk following appropriate mitigation.

A Risk Register should also cover the entire project timeline from the moment of use onwards, including:

  • Pre-project feasibility

  • On-going project contracting and construction

  • Post-construction operation and maintenance.

As such, Risk Registers can be sub-divided into Sections and/or Phases such as: Project Management, Business Case Development, Technical Development, Planning, Procurement, Installation and On-going Operation. Other phases may apply. Equally, risks can be organised thematically, for example ‘environmental’, ‘financial’, ‘managerial’ etc.

Risk Registers are often developed as simple spreadsheets, since they’re easy to create and modify.

Colour-coding

Risk Registers can be coded with colours, or with a numerical system, to clearly indicate the severity of the risks you identify. This should be done both before and after appropriate mitigation measures have been considered. 

Colour coding can be done with a simple Green –> Amber –> Red system, from lowest to highest severity. A numerical system can be implemented, for example, by giving ‘Probability’ and ‘Impact’ each a score out of 5 – with multiplication of one by the other giving each risk a score out of 25.

Here’s an example:

Building a Risk Register for a Greenspace Heat Pump Project

Below is an example of a risk register, covering some of the issues that are likely to be encountered during the project lifecycle for green space heat pump schemes. It is intended to get the user started with the risk register process – users will need to add to and edit this basic Register to suit the specific barriers and context of the greenspace in question.

TaskRisk descriptionProbability of OccurrencePotential ImpactRisk TreatmentOverall Risk Score After Mitigation
Phase: On-going
All tasks involving internal resourcesCapacity limitations and low prioritisation of green space heat project development inhibit progressMediumHighRecognition by management of strategic value of green space heat project development. Preparation of a mini-business case for project development itself, focusing on strategy-relevant benefits. Maintaining a clear and achievable project timeline (including decision-points) which allows any time-limited benefits to be secured. Appointment of a project “champion”.Medium
Phase: Opportunity Search and Feasibility Assessment
Matching supply and demand within identified constraintsStrong opportunities are indicated in fewer locations than expected, limiting the scope for multiplying the benefits through replication.LowMediumIncluding opportunities across a range of scales and different types of green space (not necessarily just parks) in the search.Low
Financial evaluation and business case developmentEconomic and Financial cases are insufficiently strong/conclusive to proceed with the development of shortlisted opportunities.MediumHighHighlighting the wider Strategic Case in proposals, especially the project’s contribution to the localisation of energy and decarbonisation (including net-zero pledges where applicable).Medium
Stakeholder engagementLocal stakeholders (e.g. community, commercial) present opposition to proposal.LowMediumUndertaking stakeholder identification and mapping early on in the project. Early engagement with stakeholders whose participation is critical (e.g. potential heat customers).Low
Phase: Project Development
Financial modellingRefinement of technical, financial and management details of proposed scheme results in a weakened business case.MediumHighUndertaking value engineering exercise to try to improve the business case; otherwise, revisiting the shortlist of opportunities in case a new frontrunner can be identified.Medium
Customer acquisition and contractual sign-upPotential heat customers do not connect to scheme:
· Property developers opt to install conventional heating systems rather than take up heat supply offer.
· Existing heat users decline offer of connection.
LowHighEngaging with owners/tenants (and/or building managers) of existing buildings and with property developers to persuade them of the benefits of opting for heat supply from green space scheme.Low
Planning and consentingRegulatory consent (e.g. planning permission where required, natural heritage) are delayed or not achieved.LowHighEarly engagement with planning and regulatory authorities to identify information requirements, use of appropriately qualified professionals to develop required information, and sharing issues at an early stage to understand regulatory implications. .Low
ProcurementCapital costs exceed estimated budget (e.g. large electrical network connection costs are required).MediumMediumPre-tender engagement with multiple suppliers to inform the cost estimate on which to base the business case (including a contingency sum). Competitive tendering to secure value for money.Medium
Phase: Operational
Revenue generationPrice changes in gas and electricity markets decrease cost savings/net revenues from scheme.MediumLowPre-construction modelling to review heating fuel and electricity market trends. Incorporation of cashflow buffers and/or medium-term budgeting to be based on the results of a sensitivity analysis which quantifies the impact of a “low”, “medium” and “high” scenario.Low
Technical operationTechnical design flaws or defective installation mean that the system fails to perform to required standards, resulting in i) increased running costs; ii) an under-heated building; and/or iii) operation and maintenance issues.LowLowAdherence to Microgeneration Certification Scheme requirements will help to ensure an effective design and good quality installation for smaller schemes. Larger schemes can require designers/installers comply with CIBSE code of conduct. Construction contract can cover the early period in which technical flaws are most likely to emerge (typically within the first one to two years), and place appropriate remediation responsibility on the contractor.Low
TechnicalEquipment fails prematurely and requires replacement.LowMediumService Heat Pumps annually; ensure they come with a 5-year warranty, providing certainty that no additional costs relating to equipment will accrue in the early years of the scheme’s operation.Low
