Caribbean ParkDLL and RenewCORP Solar Project
Delivering large-scale renewable energy across a multi-building commercial precinct
A precinct-wide energy transformation
Caribbean Park has been shaped by one family's long-term vision for more than 80 years. When the time came to elevate the precinct's sustainability performance, the Spooner family brought together partners aligned to delivering a precinct-wide transformation - rather than engaging a traditional contractor.
RenewCORP was engaged to lead a comprehensive energy strategy across Caribbean Park's six-building commercial portfolio. Through a structured, data-led assessment, a clear pathway emerged to significantly improve energy performance and integrate large-scale renewable generation across the site. The result was a 720 kW rooftop solar installation spanning all six buildings, completed and commissioned in December 2025.
“This wasn't about a single upgrade, it was about taking a long-term view of how the precinct operates and where we want it to be in the future. By bringing the right partners together, we were able to move beyond incremental change and deliver something at a scale that genuinely shifts performance. It sets a new benchmark for what a commercial precinct like this can achieve.”

Strategy, scale and financing - all at once
Delivering a precinct-wide solar programme across six buildings is a different exercise to a standard single-site rollout. The challenge required strategy, engineering, delivery, and structured financing to work together from the outset:
- Delivering a precinct-wide energy strategy across six distinct commercial buildings simultaneously
- Aligning a large-scale solar rollout with Caribbean Park's long-term asset strategy and NABERS rating aspirations
- Coordinating installation, commissioning, and programme management at scale without disrupting tenant operations
- Structuring financing to make the investment accessible and cash flow positive over the long term
Strategy, engineering and delivery - brought together.
Data-led energy strategy assessment
RenewCORP conducted a structured assessment across the full commercial portfolio before any works commenced.
- Analysed energy consumption and grid reliance across all six buildings
- Identified the optimal pathway for renewable generation integration at precinct scale
- Developed a clear programme aligned to Caribbean Park's long-term sustainability objectives
- Produced a commercially structured recommendation that enabled the project to move at pace
Multi-building solar installation
The 720 kW installation was delivered across all six buildings and commissioned in December 2025.
- Rooftop solar across the entire six-building portfolio, coordinated as a single programme
- Delivery managed to minimise disruption to Caribbean Park's tenants throughout
- System engineered to generate approximately 945,000 kWh of renewable energy annually
- Estimated to prevent upwards of 819 tonnes of CO₂e from entering the atmosphere each year
Structured financing with DLL
DLL's involvement as financing partner was critical to delivering the project at this scale and pace.
- 100% of the solar system - including installation - financed with no upfront capital required
- Financing term aligned to the project's economic profile for optimal long-term returns
- Investment expected to be cash flow neutral for the first seven years and positive thereafter
- Enabled Caribbean Park to realise immediate energy savings while maintaining cash flow stability
“Caribbean Park took a long-term view of where the precinct needed to go, and it's the kind of mandate RenewCORP is built to deliver against. Bringing strategy, engineering and delivery together across six buildings is a different exercise to a standard rollout, and DLL's role as financing partner was critical in enabling us to execute at this scale and pace.”
David Erczmann, Head of Partnerships, RenewCORP
DLL - enabling scale and pace
DLL* supported the project as financing partner, enabling the programme to be delivered at scale and within a defined timeframe. Their involvement ensured the initiative could move forward efficiently while aligning with Caribbean Park's long-term asset strategy. With a financed model, the investment is expected to be cash flow neutral for the first seven years and positive thereafter.
“DLL partnered with Caribbean Park and RenewCORP to structure a tailored financing solution that funded 100% of the solar system, including installation. By aligning the financing term with the project's economic profile, DLL enabled the deployment to be delivered with no upfront capital while supporting strong long-term financial returns. This approach allows Caribbean Park to realise immediate energy savings and sustainability benefits, while maintaining cash flow stability in the early years and unlocking significant positive cash flow over the life of the system.”

Environmental and operational impact
- A 720 kW rooftop solar installation delivered across six commercial buildings and commissioned December 2025
- Estimated 945,000 kWh of renewable energy generated annually across the precinct
- Estimated 819+ tonnes of CO₂e prevented from entering the atmosphere each year
- Net 0.5 stars added to each NABERS Energy Rating - strengthening the precinct's appeal to institutional and large corporate lessees
- A 6 Star NABERS Energy rating across all buildings now firmly in view - a first for the suburban commercial office market
- Cash flow neutral for the first seven years; materially positive cash flow over the life of the system
Caribbean Park now stands as a leading example of how commercial precincts can evolve to meet the expectations of modern tenants while maintaining a focus on performance, sustainability and long-term value.
