Tertiary & Group Colleges (Multi-Site Corps): solar panels for colleges

Group / multi-site corps — strongest unit economics in the FE sector

Group colleges — multi-site FE corporations operating 3 to 15 campuses under a single corporation board — represent the largest single FE entities by learner volume. The category includes NCG (Newcastle College Group, with 7 campuses nationally including Lewisham, Southwark, West Lancashire, Carlisle, Kidderminster, Trafford), LTE Group (The Manchester College, 6 campuses), Capital City College Group (3 colleges), Activate Learning (6 campuses across Reading, Oxford, Bracknell, Banbury, Guildford, Wokingham), Luminate Education Group (Leeds City College plus Keighley and Harrogate), RNN Group, DN Colleges Group, City of Bristol College, BMet Birmingham Metropolitan, City of Wolverhampton, Education Partnership North East (EPNE), South Thames Colleges Group, and others. The economics of a portfolio solar programme across a group are markedly better than single-site work: one Salix or PSDS bid covers the whole portfolio, procurement is consolidated, DNO liaison is parallel-tracked, monitoring rolls up to a single dashboard, and unit cost per kW drops by 15-25% at portfolio scale. Payback typically falls to 5.0-5.5 years on a Salix-funded build — comfortably the strongest in the FE sector outside land-based.

Why group corps are uniquely suited to portfolio solar programmes

• Single funding application covers everything. A single Salix Decarbonisation Loan bid can cover the entire group portfolio. One paperwork pass — energy savings calculation aggregated across campuses, corporation board approval at the group level, repayment from group-wide energy savings. Saves 6-9 months versus campus-by-campus applications.
• Procurement economies of scale. Portfolio-scale procurement of panels, inverters, mounting kit, and battery storage drives unit cost down. At 1.5 MW total programme scale we see £700-£850/kW installed versus £900-£1,100/kW for single-site work.
• Consolidated DNO liaison. Each campus needs its own G99 application but a single DNO liaison resource (us) manages the parallel timelines, reducing chasing and slippage. Several DNOs offer streamlined multi-site processing for portfolio applications.
• Phased delivery aligned with term-time windows. A portfolio rollout across 5-7 campuses typically spans 2-3 summer break windows, so the corporation never has more than one campus disrupted at a time. Sequencing maps onto your corporation's academic calendar.
• Single monitoring dashboard. Group-wide live-generation monitoring rolls up to a single corporation-level dashboard, with per-campus drill-down. Climate Action Plan reporting is markedly easier at portfolio scale than across separately monitored sites.

Designing the right portfolio programme for a group corp

We start with a portfolio-wide energy audit — half-hourly meter data from every campus, baseline electricity demand by daypart, identifying the campuses with highest energy intensity and biggest roof area opportunities. Typical portfolio sequencing: 60% of the capacity on the largest 2-3 campuses (main teaching blocks of 10,000+ sqm, large workshop or sports hall complexes), 30% spread across mid-size campuses, 10% on smaller annexes or adult community centres. Battery storage often goes on the largest sites where evening and weekend export would otherwise be high. Inverter strategy is standardised across the portfolio for monitoring simplicity — typically the same string inverter family across all campuses for service consistency. The Salix bid is built campus-by-campus with energy savings calculations rolled up to the portfolio total; the corporation board approval minute is single-shot for the whole programme. Phasing typically spans two summer windows for portfolios up to 10 campuses, three summers for the largest (NCG-scale). We provide a single point of contact across the group corp for the duration of the programme — design, build, commissioning, and 12-month post-install monitoring.

Funding routes for group corp portfolio solar

**Salix Decarbonisation Loan** is the default — interest-free up to £600k per project (and Salix has historically been flexible about treating a multi-site programme as a single project where it is governed by a single corporation board). For larger group programmes (over £600k total), some have been structured as multiple sequential Salix applications, or have included a **PSDS Phase 4** capital grant element on top — particularly where the portfolio pairs solar with heat decarbonisation across multiple sites. The **FE Capital Transformation Fund** has supported larger group estate programmes where solar is embedded inside a wider strategic estates plan. **Mayoral Combined Authority schemes** apply to specific campuses within devolved areas — group corps operating across multiple MCA regions (NCG is a striking example with campuses from Carlisle to Lewisham) can stack devolved funding on top of Salix per relevant campus. **Smart Export Guarantee** applies — typically a smaller proportion of the business case at portfolio scale because high group-wide baseload drives self-consumption above 70%.

Compliance for group corp portfolio installs

KCSIE 2025 applies across all campuses with 16-18 cohorts — install crews are DBS-cleared and inducted per campus. ESFA Post-16 Audit Code applies; group-level capital reporting includes the portfolio programme. Per-campus considerations apply: Listed Building Consent on heritage main buildings (sometimes encountered on group corps that inherited Victorian-era buildings under incorporation); G99 DNO application per campus; asbestos management for pre-2000 estate (the great majority of group corp portfolios). Skills England transition (June 2025) means group corp project rationale should explicitly tie to skills and sustainability outcomes — group corp Climate Action Plans typically already include this. AoC Climate Action Roadmap reporting at group level rolls up per-campus per-system data. The single biggest scheduling complexity at group scale is calendar coordination — exam season, T-Level synoptic projects, apprentice EPAs, and major curriculum events vary slightly between campuses, so portfolio rollouts need clear visibility into each campus's term plan.

Worked scenario: 1.6 MW programme across an 8-campus FE group corp

An FE group corporation operating 8 campuses across the North West and Yorkshire (largest two campuses 12,000 sqm main teaching blocks, four mid-size at 6,500-9,000 sqm, two annexes at 2,500 sqm) faced a group-wide electricity bill of £4.2m in 2025. The corporation board approved a Climate Action Plan in spring 2026 with a 60% scope-2 reduction commitment by 2032. The newly appointed Group Sustainability Director (formerly Group Estates Director, with a year of CPD on net zero strategy) led a portfolio feasibility commission. We modelled all 8 campuses: 320 kW + 290 kW on the largest two, 180-220 kW on each of the four mid-size, 75-95 kW on the annexes. Total: 1,610 kW. Battery storage 500 kWh across two sites. EV charging integration on three campuses. Capex: £1,310,000 at £815/kW (portfolio scale unit cost). Funding: 70% Salix Decarbonisation Loan (£917k over 10 years at £92k/year — Salix accepted a single bid for the whole programme), 30% PSDS Phase 4 (£393k — paired with air-source heat pump installs on three sites, scored highest because of the combined carbon saving). Annual group-wide energy savings: £305,000. Net cash-flow positive £213,000/year from year one. Phased install across 3 summer break windows. Group-wide live-generation dashboard live at the group head office and at every campus reception. Featured in the AoC annual conference as case study. T-Level Green Skills cohorts across all 8 campuses ran joint synoptic projects on the install data.
