1. 1 Packaging bio- methane connections for the future Dan Anderson CEng 11 th January 2012

2. 2 The context  Utility bespoke design and build delivery model needs to evolve for the growth of renewable gas connections – approximately 250 biomethane injection plants will be required by 2020 to meet UK renewable energy targets.  Current approach:  Design and build cost is circa £650k for the injection plant (excluding connecting pipe and remote monitoring).  Lead time circa 12 months design and build (excluding remote monitoring point and remote monitoring).

3. 3 The requirement  Need a pre-approved packaged design for biogas connections with suppliers on a call off contract to provide the built units to site  Key components: 1.Develop a fit for purpose cost-effective engineering specification for a packaged solution. 2.Develop a tender to source suppliers who can provide pre- approved packaged designs to meet the specification, which they can supply to site ready built. 3.Allow the concept to be future-proofed as ownership may not be with the GDN and regulatory requirements will change.

4. 4 The scope of the basic package Instrumentation links Pressure Reduction Gas Analyser Fiscal Metering Odorant Injection Electrical transformer and electrical distribution system Process Shut down valve Housing for the unit / component parts Gas produced by biomethane producer clean up plant (to include propane enrichment) FWACV Gas Quality and supervisory system Gas Grid Downstream remote monitoring option DB1Telemetry Unit To Control Centre To Bio Methane producer

5. 5 Approach to a packaged design Basic packaged approved design (G19) Mechanical Electrical Instrumentation Software (approach) Site specific design (G17) Telemetry Civil Site specific software TD/13 Industry Standards Company policies derived from Electricty at Work Regulations and British Standards User requirements specification / Functional Design / Software Design Spec, Test Procedures, Functional Blocks FWACV

6. 6 The journey to a packaged solution Contract award Bid for first call off Build procurement strategy Work with Multi-disciplined engineering team – identify the sub systems and draw out the key requirements for each Engineering Integrity sign on Issue full tender Provide technical guidance and manage the input of technical experts to ensure the needs of the application are met Manage technical issues with suppliers input into design development Build support for the concept

7. 7 How the call off arrangement will work New connection Supplier 2 Supplier 3 Supplier 4 Supplier 1 Complete telemetry / civil / pipework design Mini tender Select supplier Gas quality assessment Hazop with chosen supplier Call off Contract Supplier to produce site specific design amendments to basic package Unit built Install and commission

8. 8 Integration into the future Biogas Clean up PRS Vol. Meter GC Gas Grid FWACV configurable supervisory and control system Odour DB1 Telemetry GDN (Logic Control) DNCC DFOGDN Odour DFOGDN

9. 9 The outcomes  Packaged designs which can operate over the following operating conditions:  Pressure  Max inlet of 7 bar and Min outlet of 75mb  Flow  20m3/h - 2000m3/h  Size  Equal in scale to a shipping container

10. 10 The outcomes  Substantial cost saving  Lead times of 5-6 months (for supply to site)  Four suppliers are involved in the tender who can now be approached by DFOs/other GDNs should they wish to purchase a packaged unit.  Technica Ltd  Elster-Instromet  Orbital Gas Systems  Biogast/Future Energy Group Ltd  The work puts in place a platform for the industry to build from into the future.
