The platform, the partner, and the place.
Green Roof Philippines is the Philippine entity of CN Green Roof Asia (CNGRA) — the Southeast Asian renewable energy platform that Rob led as CEO during 2022–2025. CNGRA itself is a joint venture between Climate Fund Managers (through the Climate Investor One blended-finance facility) and Norfund (the Norwegian government's investment fund for developing countries). The platform built and operated a roughly $80 million renewables portfolio across Vietnam, Cambodia, Indonesia, and the Philippines.
The Hermosa project entered the platform's pipeline through Solana Renewable Energy Holdings, a local Philippine development partner who originated the early site work — site identification, preliminary land arrangements, initial permitting groundwork, and the foundational engagement with the host barangay and municipality. As the project moved toward construction-grade development, Solana handed over to Green Roof Philippines as the developing platform, and the special-purpose vehicle Solana Solar Beta Inc. was established to own and operate the asset. The project carries Solana's name through the SPV in recognition of that origination heritage.
Under Rob's CEO tenure at CN Green Roof Asia, Green Roof Philippines was set up as a locally-staffed in-country platform — not a remote-managed Vietnamese arm. The local team was hired, built, and trained to run the construction phase on the ground in Bataan and to operate the asset post-commissioning. This wasn't ancillary to the project; it was the spine of how the institutional-capital sponsorship structure was actually delivered. The team Green Roof Philippines stood up in 2024–2025 is the same team running the plant today.
Bataan is on the western edge of Luzon, with longstanding industrial activity around Subic Bay and emerging development through the Subic-Hermosa Cybercity Special Economic Zone. The Municipality of Hermosa sits within the franchise area of Peninsula Electric Cooperative (PENELCO), the local distribution utility serving the province. Like much of the regional power supply on this part of Luzon, PENELCO's franchise has been operating against tightening reserve margins and growing demand — making locally-sited renewable generation under embedded-PSA structures a credible part of the cooperative's supply mix.
Why this project was different from the rooftop portfolio.
Most of the CNGRA platform's deployed capacity sits in Vietnamese C&I rooftop solar — Zero Capex PPAs at multinational customers, the model originally piloted at Coats Phong Phu in 2019 and generalised across Korean MNCs and others (the Lotte Chemical sister deep-dive covers the IP-grid extension of that pattern). Solana Hermosa is structurally a different asset:
- Utility ground-mount, not C&I rooftop. 22.785 MWp on dedicated land, single-site large-scale generation rather than distributed rooftop installations across multiple sites.
- Equity-financed by climate-focused institutional capital, not Zero Capex PPA. CFM and Norfund equity at the platform level; SPV-level project structuring; no customer-side balance-sheet involvement.
- Distribution-utility offtake under PSA, not C&I bilateral PPA. A Power Supply Agreement with an electric cooperative, embedded into PENELCO's supply mix, not a discrete corporate offtaker.
- Cross-border platform execution. Vietnam-headquartered platform delivering a Philippine asset, navigating Philippine permitting, Philippine ES&HS standards, and Philippine regulatory bodies (DOE, ERC, DENR, NCIP).
What that meant in practice was a project that needed to clear an entirely different operational discipline from the rooftop portfolio. Institutional climate capital — particularly blended-finance vehicles like Climate Investor One backed by Norfund — applies IFC-aligned Environmental, Social, Health and Safety (ES&HS) standards as a precondition for deployment. That envelope is non-negotiable. It governs the whole project lifecycle: pre-construction studies, biodiversity protection, formal public consultation, labour standards, community development commitments, ongoing monitoring, and grievance mechanisms. The technical work was a 22.785 MWp ground-mount build. The discipline that surrounded it was the institutional-grade ES&HS envelope.
How the project actually came together.
Origination, transition, and platform build-out
Solana Renewable Energy Holdings carried the project through the early development phase — site identification and land assembly in Barangay Balsik, foundational engagement with the host barangay and the Sangguniang Bayan of Hermosa, preliminary permitting, and the technical-feasibility groundwork. As the project matured toward construction-grade, Green Roof Philippines took it through the platform's institutional-capital sponsorship structure, established Solana Solar Beta Inc. as the asset-holding SPV, and brought the project into the CFM/Norfund portfolio. The local-developer-to-platform transition is a model the CNGRA platform repeated elsewhere in its Philippine pipeline.
Building the local team
Green Roof Philippines was established not as a project office but as a standing local platform with its own staff, country leadership, and operational capability. Through 2024 and into 2025, the team was hired and built up to handle the full construction phase on the ground in Bataan: project management, site supervision, EPC contractor coordination, ES&HS compliance, regulatory engagement with DOE, ERC, DENR, NCIP, the local government units, and PENELCO. Post-commissioning, the same team carries operations and maintenance, ongoing community engagement, and continuing ES&HS reporting against the institutional-capital envelope.
This is a meaningful structural choice. Many cross-border developers run Philippine assets through a project-specific SPV with thin local presence and remote head-office direction. Green Roof Philippines was built the other way: country-level platform first, project SPVs underneath. The cost of that approach in the early years is higher overhead and a longer ramp; the dividend is execution-grade reliability when an institutional-capital project hits the construction phase, and operational continuity across the asset's full lifecycle.
The PSA with PENELCO
In June 2025, Solana Solar Beta Inc. signed a Power Supply Agreement with PENELCO covering 10 MW of the plant's output, embedding the project directly into the cooperative's supply mix. The structure aligns with the Philippines' Renewable Portfolio Standards (RPS) compliance framework and contributes to the national 35% renewable energy target. From PENELCO's perspective, locally-embedded solar shortens the supply chain, reduces transmission exposure, and gives the cooperative a long-term hedge against regional reserve-margin pressure.
At the groundbreaking, PENELCO's General Manager framed the partnership as a step toward more affordable and reliable electricity for Bataan, aligned with the Philippines' renewable energy targets and the cooperative's stewardship of regional power supply.
The IFC-aligned ES&HS envelope
The institutional-capital backing brought a structured ES&HS envelope to the project from inception, governing how it was developed, how the local community was engaged, and how the construction footprint interacted with the natural environment. Three components stand out as the most visible in the public record:
Formal disclosure activity
Public Consultation and Disclosure Activity held 16 July 2025 at Barangay Balsik — formally announcing construction commencement, presenting the project envelope, and engaging the host community on impacts and benefits.
Narra tree protection
Earth-balling and relocation of mature Narra trees (Pterocarpus indicus — the Philippine national tree, IUCN endangered) on the construction footprint, rather than felling — preserving the heritage canopy on the site.
Solar-Powered Irrigation Systems
Community Development Programme delivering Solar-Powered Irrigation Systems (SPIS) to local farmer associations in the host municipality — translating project benefits into year-round agricultural productivity uplift.
Each of these is operationally expensive relative to a non-institutional build. The Narra relocation in particular is logistically and financially heavier than felling-and-replanting; the public consultation generates documentation requirements that go beyond standard Philippine permitting; the Community Development Programme is funded outside the bare-cost project envelope. That cost differential is the price of the institutional-capital relationship — and it is the discipline that makes the asset bankable for IFC-aligned investors at scale.
Construction and commissioning
Construction commenced 11 July 2025. From construction start to commercial operation, the project was completed in approximately nine months — a tight schedule for a 22.785 MWp ground-mount build with full institutional-grade ES&HS compliance and embedded-PSA grid integration. The plant reached commercial operation in April 2026 and is now generating into PENELCO's supply mix.
What the project delivered, and what it set up after.
At commercial operation, Solana Hermosa delivers against four operational targets: 22.785 MWp installed; expected annual generation of 32.8 GWh; expected annual carbon offset of 14,053 tonnes; service to nearly 30,000 individuals annually through PENELCO's franchise area. Over 100 jobs were generated during construction. The Community Development Programme is in operation; the Narra trees that were relocated are integrated into the operational site.
Beyond the operational numbers, three things mattered more in the longer arc:
- The CNGRA platform proved it could deliver institutional-grade utility-scale assets in a cross-border context. Most of the platform's deployed capacity was Vietnamese C&I rooftop. Solana Hermosa demonstrated that the same operating discipline scaled to ground-mount utility solar in the Philippines — different asset class, different country, different regulatory regime, same operational standard.
- The local-developer-to-platform transition is a repeatable model — provided the platform builds on the ground. Solana Renewable Energy Holdings originated the Hermosa project; Green Roof Philippines took it through to construction and operation, with a locally-staffed in-country team that was hired, trained, and put in place specifically to run delivery. The structure of that handover — recognising local origination through the SPV name and partnership structure, while bringing the institutional-capital sponsorship and ES&HS envelope from the platform side, and underpinning both with a real country-level operational capability — is a template the CNGRA platform repeated and that translates to other developing-market contexts.
- The ES&HS discipline is increasingly the price of admission for capital, including in Vietnamese C&I. What Climate Fund Managers and Norfund required at Solana Hermosa is converging with what international project lenders, multinational corporate offtakers, and ESG-conscious investors are starting to require for Vietnamese C&I solar and BESS projects — particularly those over $5 million. The discipline isn't a Philippines-specific overlay; it is the direction the whole regional market is moving.
Operational and generating into PENELCO's supply mix.
Solana Hermosa reached commercial operation in April 2026 and is currently generating clean electricity into PENELCO's franchise area under the Power Supply Agreement signed in June 2025. The asset is owned by Solana Solar Beta Inc., the special-purpose vehicle established by Green Roof Philippines for the project. Ongoing operations and maintenance sit with the Green Roof Philippines platform.
The operating background transfers. The platform doesn't.
Solana Hermosa was developed and built under Rob's tenure as CEO of CN Green Roof Asia. The project, the SPV, the customer relationship with PENELCO, and the ongoing O&M obligations all sit with the Green Roof Philippines platform — they are not Arcus Energy assets, and they are not Rob's personal contracts. Arcus is a separate, independent advisory practice; the Solana Hermosa project documentation does not move with Rob.
What does transfer is the operating background. The discipline of structuring an embedded-PSA project under IFC-aligned ES&HS standards in a Southeast Asian developing-market context. The cross-border platform-execution experience moving institutional climate capital from CFM/Norfund equity through SPV structuring to a commissioned utility-scale asset. The local-developer-to-platform transition that brought Solana Renewable Energy Holdings' origination work through to a CFM/Norfund-grade build. And — substantively — the experience of standing up a country-level operating platform from zero: hiring, training, and putting in place the in-country team that carried construction and now runs operations. None of that is project documentation — it sits in the operating fluency that informs Arcus's advisory work today, particularly for clients evaluating institutional capital structures, ES&HS-graded asset development, cross-border C&I energy infrastructure, or the question of whether to run a country through a project office or a standing local platform.
This page is a track-record case study, not a current Arcus customer reference. Where current Arcus engagements reach commercial close with publishable customer references, those will appear on the case-studies page separately and clearly distinguished from the prior-role record.
Three lessons from Solana Hermosa that apply across the region.
These are the operating heuristics the Green Roof Philippines team built around the Hermosa project and the broader CNGRA Philippine pipeline. They continue to shape how Arcus approaches energy advisory work in Southeast Asia, particularly for clients moving from owner-financed C&I projects toward institutional-capital-grade asset structures.
1. The ES&HS envelope is not a compliance overhead — it is the asset's relationship with its capital.
Climate Fund Managers, Norfund, and similar institutional climate investors apply IFC-aligned ES&HS standards as a precondition for deployment, not as a regulatory minimum to be navigated. For projects targeting that capital, the public consultation, biodiversity protection, community development programme, and labour standards aren't items to be ticked off the bottom of the budget — they are the operational substance of why the capital is willing to invest. Vietnamese C&I solar and BESS projects targeting international project finance, multinational corporate offtake, or ESG-aligned equity should treat the envelope the same way from inception, rather than retrofitting it under audit pressure later.
2. Cross-border project execution lives or dies on the country-level operating platform.
Solana Renewable Energy Holdings originated; Green Roof Philippines built and operates. The model — local developer originates with their host-community advantage and early permitting work, institutional-capital platform takes the project through to a financeable, ES&HS-graded build with a properly-staffed local team — is reproducible across the region, but the second half of that sentence is doing more work than the first. A platform with thin local presence and strong head-office direction does not deliver an institutional-grade asset reliably. A platform with a real country team built on the ground does. For developers operating in Vietnam who want to access institutional climate capital, the question is whether the project pipeline sits at a stage where a platform like CNGRA, Berkeley Energy, AC Energy, or others can sponsor it through to construction with a real local execution capability — not just sponsor it on paper. That answer is not always obvious and often shapes the right next move.
3. Ground-mount discipline informs C&I rooftop discipline.
The operational standards required for a 22.785 MWp utility-scale embedded-PSA project under institutional capital are exacting. The good news for the Vietnamese C&I market is that those standards are increasingly converging with what international corporate offtakers and project lenders expect even for rooftop-scale work. A C&I solar developer who has delivered against IFC-aligned ES&HS standards on a ground-mount project carries that discipline forward; a developer who hasn't will face a steeper learning curve as institutional capital deepens its presence in Vietnamese C&I over the next few years. Both Decree 57's DPPA framework and Resolution 253/2025's price-liberalisation provisions are pulling C&I project structures closer to institutional-grade norms — the discipline gap is narrowing in both directions.
