SunCable's collapse in January 2023 was a textbook case of the 'missing middle' in climate infrastructure finance—the chasm between development capital and construction capital...
SunCable \Australia
SunCable was an audacious infrastructure megaproject aiming to build the world's largest solar farm in Australia's Northern Territory (10GW capacity) and transmit renewable energy 4,200km via subsea cable to Singapore, supplying up to 15% of the city-state's electricity needs. The value proposition was threefold: (1) Leverage Australia's abundant solar resources and land availability, (2) Address Singapore's energy security and decarbonization goals as a land-constrained nation heavily reliant on natural gas imports, and (3) Prove the technical and commercial viability of intercontinental renewable energy transmission at unprecedented scale. The 'why now' was driven by plummeting solar costs (70% decline 2010-2020), Singapore's 2030 net-zero commitments, rising ESG investor appetite for climate infrastructure, and geopolitical shifts favoring energy independence. SunCable positioned itself as the Tesla Gigafactory equivalent for solar-plus-transmission, targeting a $30B total project cost with first power delivery by 2027-2028. The startup secured backing from Atlassian co-founder Mike Cannon-Brookes and Fortescue's Andrew Forrest, raising $130M+ in development capital to advance engineering studies, environmental approvals, and offtake negotiations with Singapore's SP Group.

Difficulty
SunCable's rebuild difficulty remains extreme (5/5) even with modern tools because the core challenge is physical infrastructure at unprecedented scale, not software. The project...
Scalability
SunCable's scalability was fundamentally constrained by the capital-intensive, linear nature of energy infrastructure. Unlike software with near-zero marginal costs, each additional GW of capacity...

Execution Plan
Phase 2
**Step 2 (Validation - Months 5-8): Expand to Offtake Matching + 3 New States.** Add AI contract negotiation module: Integrate with corporate buyer APIs (Microsoft, Amazon, Google procurement systems) to auto-match solar projects with companies needing renewable PPAs. Use GPT-4 to generate 20-year PPA term sheets based on project economics + buyer's carbon goals. Expand geographically to California, Arizona, Florida (covering 60% of US solar pipeline). Pricing: $100K base + $500K success fee at financial close. Target: 30 projects, 10 reach financial close = $3M base + $5M fees = $8M revenue. Validation: If 30%+ conversion to financial close, the AI is genuinely de-risking projects (vs. industry 10-15% rate).
Phase 3
**Step 3 (Growth - Months 9-18): Launch Full Platform + International Expansion.** Build end-to-end platform: (1) Site selection AI (satellite data → optimal locations), (2) Permit automation (all 50 US states + Australia, Spain, Chile), (3) Offtake marketplace (500+ corporate buyers), (4) Financing copilot (auto-generates lender-ready financial models, connects to project finance banks). Hire ex-NextEra and ex-Brookfield developers as 'AI trainers' to fine-tune models on their internal playbooks. Pricing: $500K/project + 0.5% success fee. Target: 100 projects/year, 40% close rate = $50M SaaS + $100M fees = $150M revenue. Growth loop: Each successful project becomes a case study → attracts more developers → more data → better AI → higher close rates. International focus: Australia (post-SunCable, huge pipeline), Spain (EU's largest solar market), Chile (cheapest solar globally).
Phase 4
**Step 4 (Moat - Months 19-36): Become an Investor + Build Regulatory Moat.** Use $150M revenue to raise $500M fund (GridForge Ventures) to co-invest in top 20 projects/year (5-10% equity each). This creates a flywheel: GridForge has insider access to the best projects → negotiates data-sharing agreements (all project data feeds back into AI) → becomes the only platform with real-time project performance data (actual vs. modeled solar output, O&M costs, offtake pricing). Regulatory moat: Lobby for 'AI-approved permits' to get fast-track status (precedent: FAA's approval of SpaceX's AI-based launch licensing). Partner with DOE, EU Commission to make GridForge the standard for IRA and REPowerEU compliance checks. End state: 50% of new renewable projects use GridForge (2,000 projects/year × $500K = $1B SaaS revenue) + $200M/year in success fees + $2B fund returning 3x = $6B in carry over 10 years. Exit: IPO at $10B valuation (comp: Nextracker, solar tracker company, IPO'd at $8B in 2023) or acquisition by Brookfield/Blackstone as their AI infrastructure arm.
Monetization Strategy
GridForge uses a hybrid SaaS + success fee model optimized for high-ACV, long-sales-cycle infrastructure projects: (1) **Base SaaS Fee ($500K/project):** Charged upfront for access to the platform (permit automation, site selection AI, offtake matching, financial modeling). This covers 12 months of support through development phase. Justification: Customers currently spend $2-5M on consultants (ERM, Bechtel, Norton Rose) for the same deliverables; GridForge is 75% cheaper and 10x faster. (2) **Success Fee (0.5% of project CapEx at financial close):** Charged only when the project secures construction financing (average project size $500M = $2.5M fee). This aligns incentives—GridForge only wins if the customer wins—and captures the massive value creation (a project reaching financial close is worth 50-100x more than a feasibility study). (3) **Offtake Marketplace Take Rate (2% of PPA value):** For projects using GridForge's AI to negotiate corporate PPAs, charge 2% of the 20-year contract value (e.g., $500M PPA = $10M fee, paid over 3 years). This is cheaper than traditional brokers (5-10%) and automated via smart contracts. (4) **Data Licensing ($1M/year per enterprise):** Sell anonymized, aggregated project data to utilities, investors, and governments (e.g., 'solar irradiance vs. actual output' datasets, 'permit approval timelines by jurisdiction'). 50 enterprise customers = $50M/year high-margin revenue. (5) **GridForge Ventures (2% management fee + 20% carry):** The $500M co-investment fund charges standard VC fees, generating $10M/year management fees + $200M+ in carry over 10 years if the portfolio 3xs. Total revenue model at scale (Year 5): 200 projects × $500K SaaS = $100M | 80 projects close × $2.5M success fee = $200M | 50 PPAs × $10M take rate = $500M (amortized over 3 years = $167M/year) | 50 data customers × $1M = $50M | Fund fees = $10M | **Total: $527M/year revenue, 60% gross margin (AI has near-zero marginal cost after training).** Path to $1B revenue: Scale to 400 projects/year (still <20% market share of the 2,000+ utility-scale projects annually) + expand to wind, transmission, and green hydrogen. Exit comps: Nextracker (solar hardware) IPO'd at $8B on $500M revenue; GridForge's software margins (60% vs. 20% hardware) justify a $10-15B valuation at $1B revenue.
