1 Lincolnshire Low Carbon Hub Steven Burns

2 Background to the Hub Progress Learning Next Steps Presentation Outline mVA Harmonics Voltage Foot print Site Layout

3 Project Background

4 Year 1 Tier 2 Project Total Budget£3.4m LCNF £3m Objectives Demonstrate 6 innovative techniques Make it easier for generation to connect Develop an investment ahead of need concept Lincolnshire Low Carbon Hub

5 Existing 33kV Network Layout

6 Dynamic Line Rating Network Enhancements Commercial Agreements FACTs Dynamic Voltage Control 33kV Active Ring Low Carbon Hub Network Elements of the Hub

7 Proposed Layout

8 Progress To Date

9 FACTS Specification complete FACTS ITT Issued and being scored Wayleaves for OHL rebuild well underway Harmonisation with works at Trusthorpe Progress to Date Trusthorpe

10

11 New 4.5km Overhead Line Local opposition Unintended Consequences Investment ahead of need Vs business need Compulsory wayleaves a last resort Not appropriate in this scenario

12 Proposed Revised Layout

13 TRUSTHORPE ALFORD CHAPEL ST LEONARDS INGOLDMELLS SKEGNESS 33kV NO Tee SPILSBY s Current Layout BAMBERS FARM

14 TRUSTHORPE ALFORD CHAPEL ST LEONARDS INGOLDMELLS SKEGNESS 33kV NO Tee SPILSBY s Current Layout - 2 Radial Feeders BAMBERS FARM

15 TRUSTHORPE ALFORD CHAPEL ST LEONARDS INGOLDMELLS SKEGNESS 33kV NO Tee SPILSBY s Outline Ring Design BAMBERS FARM FACTS

17 TRUSTHORPE ALFORD CHAPEL ST LEONARDS INGOLDMELLS SKEGNESS 33kV NO Tee SPILSBY s Design 1: Full Unit Protection Scheme BAMBERS FARM FACTS Proposed 9MW Wind Farm s NO 7 Panel Board 6 Panel Board 3 Panel Board Unit Protection

18 Design 1: Full Unit Protection Scheme Time – Offline Build, but stretching Cost - £1.3m over budget Quality - Significant Network Improvement Project - Full rebuild not in ethos of scheme

19 ALFORD CHAPEL ST LEONARDS INGOLDMELLS SKEGNESS 33kV NO Tee SPILSBY s Design 2 : Minimal Unit Scheme BAMBERS FARM TRUSTHORPE FACTS s 7 Panel Board CTs and Breaker Unit Protection

20 Chapel St Leonards

21 Ingoldmells

22 Time – Online build with complex works Cost - On budget Quality - Significant site reworks, little benefit Project - High risk, complex Design 2 : Minimal Unit Scheme

23 ALFORD CHAPEL ST LEONARDS INGOLDMELLS SKEGNESS 33kV NO Tee SPILSBY s Design 3 : Minimal Scheme BAMBERS FARM TRUSTHORPE FACTS s 7 Panel Board Change Protection Distance Protection Change Protection

24 Time – Site works realistic Cost - On budget Quality - Increased protection risk Project - Delivers all 6 elements Utilises existing assets Design 3 : Minimal Scheme

25 Learning Ingoldmells

26 Unintended Consequences

27 Investment ahead of need Change Process Space to Innovate Project Continuity Re-design Time

28 Cultural change & technical change

29 Working with the business Space to Innovate Project Continuity Re-design Time Change Process
