I want to take gas on and off

Commitment

Output type

Ensure we efficiently manage the network to be able to meet a 1 in 20 peak demand severe weather event.

Licence obligation

We propose a relative Network asset risk metrics (NARM) target to measure delivery of our asset health investments with a justified over and under delivery mechanism.

Our RIIO‑2 asset health plan delivers a monetised risk output of £2.96m (measured as a level of monetised risk as part of NARMs).

Price control deliverable, (£466m).  See annex A3.01 for further information.

We are proposing a separate PCD on asset health spend that is not covered by NARMs in the following areas:

relifing of compressor cabs, site fences, site roads and replacement/refurbishment of pipe supports, pits, lighting systems and switchboards.

Price control deliverable, (£87m) See table 14.09 below and annex A3.01 for further information.

We will redevelop the Bacton terminal to meet the future customer need and allow for potential future changes (e.g. connection of storage or compression if required and the facilitation of decarbonisation). Once the redeveloped terminal is operational, the existing terminal will be decommissioned.  

Price control deliverable to reach FEED for the Bacton terminal (£4.7m). See annex A3.01.

Lower network costs compared to the alternative option of an extended and intrusive asset health programme.

Access to gas supplies, providing security of supply and helping keep wholesale gas prices as low as possible.

Redeveloping the terminal would also reduce the amount of gas at the Bacton site, moving from a top tier COMAH site to a lower tier COMAH site, reducing ongoing compliance costs for consumers.

Uncertainty mechanism to be used to adjust the requested baseline funding for the terminal redevelopment, once the final terminal design is confirmed and there is a more accurate view of the costs.

Uncertainty mechanism (£139.6m) Trigger: Year 1 (end of FEED). See annex A3.02.

UM to be used to set a second PCD for delivery of the final design.

Adoption of an uncertainty mechanism around the costs of redeveloping the terminal gives consumers cost protection from this uncertainty.

Commitment

Output type

We will build a new bi‑directional area within the boundary of the existing King’s Lynn site. This will remove any reliance on existing pipework, which is under stress due to ground subsidence.

Price control deliverable to reach FEED (£1m). See annex A3.01.)

Reopener to be used to adjust the funding allowances once the final design is confirmed and there is a more accurate view of costs.

UM to set a second PCD for delivery of the final design. (£30.2m) Trigger: Year 1 (end of FEED). See annex A3.02.

Commitment

Consumer benefit

Our asset management activities will continue to be led by good asset management principles and we will continue our external accreditation to ISO55001.

We will ensure we have the right level of human resource, trained with the right capabilities, supported by the tools, vehicles, spares and IT systems, to efficiently deliver customers’ requirements.

Commitment

Efficient management of costs, lowering consumer bills.

Contribute towards the joint gas networks emergency response and enquiry service.

Licence Obligation

Ensure gas is available as and when consumers want.

xxxxxx supports our proposal for transmission investment to increase resilience of supplies to the Blackrod offtake

Deliver a new ~1km, 900mm pipeline and a new AGI . xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

Commitment

Blackrod provides a consumer value proposition valued at £173m (for more information on CVP1 please see annex A10.05).

xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx Increased ability to undertake planned and unplanned maintenance without disruption to gas supplies/operational pressures to customers in the North West.

N/A for Tirley

Install new isolation valves that will allow individual filters at the Tirley site to be isolated and maintained. 

Commitment

Reduced risk of planned or unplanned disruption associated with filter maintenance at Tirley.

Increased security of supply and market access to diverse gas supply sources, resulting in lower costs for all consumers.

Commitment

Output type 

In response to feedback we are taking a risk‑based approach to managing the threats associated with pipeline watercourse crossings.

We will undertake condition‑based monitoring surveys of pipeline watercourse crossings to identify whether the pipeline is at risk of additional loading, impact from reduced depth of cover, exposure or free‑spanning. The drivers for this work are compliance with the Pipelines Safety Regulations 1996 and meeting the minimum requirements in the industry standard IGEM/TD/1.

Commitment

We will continue to maintain watercourse navigation markers in accordance with our obligations under the Merchant Shipping Act 1995.

Commitment

We will undertake work to assess the risk of buoyant lift on our pipelines in the event of flooding, building on our 2012 survey work.

Efficient operation of the system –we will continue to drive efficiency, understand and meet customer needs using the assets and commercial tools available to us.

Commitment

Efficient and safe operation of the network and associated commercial processes.

Efficient and safe operation of the network and associated commercial processes.

Building new capabilities – we want to exploit technologies to develop new capabilities that can drive greater value for consumers from the networks and markets, we plan to[1]:

• develop enhanced analytical and modelling tools to improve our insight to manage risks effectively
• take advantage of automation where it is cost‑effective to do so.

Efficient operation of the network and associated commercial processes ensures consumers have the gas supplies they need at the lowest possible price.

Residual balancing

Retain scheme to drive minimisation of energy costs to operate the network. Our proposals are tougher to achieve against, recognising the impact of a changing energy landscape and we propose amending the. linepack component of the scheme to drive the right behaviour during seasonal transitions between winter and summer.

ODI Current proposed cap £1.6m / collar £2.8m pa

Target (LPM): 5.6 mcm/d (shoulder months) and 2.8mcm/d (non-shoulder months)

Target (PPM):1.5% SAP

Efficiency of residual balancing activity, minimising impacts on the market, customers and ultimately cost to end consumers.

Incentive integral to our role as residual balancer.

Maintenance (use of days and changes schemes)

Retain existing schemes and expand to cover the wider range of maintenance activities supported by stakeholder feedback. Our schemes will be tougher to achieve against, recognising that the volume of planned maintenance is likely to be higher in RIIO‑2. Proposed expansion to include non-remote valve operation (RVO) maintenance.

ODI Current proposed cap £1.2m / collar £1.5m pa

Targets: Use of days – 11, Changes 7.25%

Alignment of maintenance plans with customers to minimise potential disruption to them and wider markets. Ultimately reducing costs for end consumers.

Entry and exit capacity constraint management

Retain scheme. Remove a level of risk which represents “BAU” from cost target.

Remove revenue from scheme where we scale back interruptible/off-peak capacity.

ODI

Efficient activities to avoid and manage constraints (i.e. provide the unconstrained access required by customers). This reduces overall costs and risks for consumers. Incentive integral to capacity regime (e.g. incentive efficiently managed risk associated with overselling capacity).
