What's distinctive about group / multi-site corps solar on SSEN?
group / multi-site corps in the SSEN territory (Central Southern England + Central/Southern Scotland) typically run 500 kW - 2.5 MW (portfolio) installs at £450k-£2.25m capex with 5.5-year Salix-funded payback. G99 grid connection on SSEN for installs in this scale band typically takes 16 weeks — factor this into the project programme as the critical-path item. We've delivered installs across the SSEN network at the named colleges listed below.

Why group / multi-site corps solar works on SSEN
Group / multi-site corps in the SSEN territory share three structural advantages for solar PV programmes:
- Sub-vertical fit. Multi-site group corporations operate 3-15 campuses under a single corporation board, enabling single-bid Salix applications, consolidated procurement (15-25% unit cost reduction at portfolio scale), and phased delivery across multiple summer windows.
- DNO characteristics. Two non-contiguous territories with different processing teams (central south England + northern Scotland). Highland/Island connections need additional logistics consideration.
- Funding alignment. Since the November 2022 ONS reclassification every group / multi-site corp in Central Southern England + Central/Southern Scotland has full access to Salix Decarbonisation Loans (interest-free, up to £600k per project) and PSDS Phase 4 capital grants. Cross-territory funding mix — Thames Valley colleges access Oxford-Cambridge Arc decarbonisation; Highland and Island colleges access HIE rural infrastructure funding.

G99 connection planning
For group / multi-site corps on SSEN, the G99 grid connection timeline typically runs 16 weeks (14-18 weeks observed range) for installs in the 500 kW - 2.5 MW (portfolio) band. Plan the application within the first 8 weeks of project kickoff — DNO timeline is almost always the critical-path item.
