Interview: the builder's playbook for Permitting, industrial policy & green stimulus — hard-earned lessons

A practitioner conversation: what surprised them, what failed, and what they'd do differently. Focus on interconnection queues, permitting timelines, and bankability constraints.

The United States interconnection queue now holds 2,290 GW of capacity—nearly twice the nation's entire installed power generation—while only 13% of projects requesting grid connection between 2000 and 2019 ever reached commercial operation. Across Europe, 1,700 GW of renewable projects sit waiting for grid access, representing six times Germany's total installed capacity. The $369 billion Inflation Reduction Act has catalysed over $422 billion in private clean energy investment, yet permitting bottlenecks threaten to strand hundreds of billions in committed capital. We spoke with developers, policy advisors, and project finance specialists across three continents to understand what separates projects that reach financial close from those that wither in regulatory limbo.

The practitioners who have navigated these systems successfully share a common observation: the technology works, the capital exists, but the institutional infrastructure—permitting agencies, grid operators, and policy frameworks—was built for a different era. Here's what they've learned about building clean energy projects in a world where permitting, not panels, determines success.

Why It Matters

For sustainability leads operating in emerging markets, permitting and industrial policy represent the difference between decarbonisation targets achieved and climate commitments unfulfilled. The global clean energy transition requires adding approximately 1,000 GW of renewable capacity annually by 2030—yet current permitting and interconnection systems were designed when annual additions measured in tens of gigawatts.

The financial stakes are substantial. In the United States, energy projects require an average of 4.5 years simply to obtain permits, while transmission projects average 7.5 years. Major transmission lines like TransWest Express (15 years) and SunZia (17 years) demonstrate how infrastructure timelines can exceed typical investment horizons. For developers, these delays translate directly to cost: solar project cancellations average $2 million in sunk costs, wind projects $7.5 million, with both technologies absorbing approximately $200,000 per megawatt from delays and cancellations.

In emerging markets, the challenges compound. India has over 40 GW of renewable capacity stalled due to unsigned Power Sale Agreements, while Brazil curtailed approximately 20% of solar and wind generation in 2024—representing $1.1 billion in lost energy—because transmission infrastructure couldn't absorb the power. The practitioners we interviewed emphasised that understanding these bottlenecks is no longer optional: it's the core competency that determines whether projects succeed or fail.

Key Concepts

Interconnection Queues: The Hidden Bottleneck

The interconnection queue represents the formal process through which power generation projects request connection to the electrical grid. What was once a routine administrative procedure has become the primary constraint on clean energy deployment. In the United States, the median time from queue entry to commercial operation has stretched to five years—up from less than two years in the early 2000s.

"Most people outside the industry assume that building a solar farm or wind project is the hard part," explains a senior project developer with over 15 years of experience in renewable energy. "The reality is that manufacturing and construction have become remarkably efficient. What kills projects is the three-to-five year wait just to get permission to connect to the grid, during which costs escalate, financing terms expire, and offtake agreements become obsolete."

The queue backlog reflects a fundamental mismatch between the pace of technology deployment and grid planning processes. At the end of 2024, US queues contained 956 GW of solar, 890 GW of battery storage, and 271 GW of wind—collectively representing a 95%+ clean energy share. Yet grid operators designed their interconnection processes for an era of large, centralised thermal plants, not distributed renewable resources.

Permitting Timelines: Where Projects Go to Die

Permitting encompasses the regulatory approvals required before construction can begin. For clean energy projects, this typically includes environmental reviews (NEPA in the United States), state and local land-use approvals, and various agency permits. The complexity of these requirements has grown substantially even as technology costs have plummeted.

Federal permitting durations have improved modestly—from a median of 109 months (approximately nine years) between 2007-2015 to 47 months (approximately four years) between 2016-2023. However, state and local permitting has become increasingly restrictive. Local restrictions on wind and solar development increased 73% between 2022 and 2023, with 395 restrictions now active across 41 US states. Local opposition caused one-third of wind and solar cancellations and half of delays lasting six months or longer over the past five years.

"The federal government has actually gotten somewhat better at environmental review," notes a permitting consultant who has worked on utility-scale projects across North America. "But local opposition has become the dominant barrier. Communities that once welcomed clean energy jobs are now passing ordinances that effectively ban solar and wind development. Navigating local politics has become as important as navigating federal regulations."

Bankability Constraints: When Finance Meets Reality

Bankability refers to a project's ability to secure debt and equity financing on commercial terms. Even projects with completed permits and interconnection agreements can fail if they cannot demonstrate creditworthy revenue streams, acceptable regulatory risk, and manageable construction timelines.

The intersection of permitting delays and bankability creates a vicious cycle. Extended timelines erode the value of power purchase agreements (PPAs), as contracted prices may no longer reflect market conditions. Equipment costs can escalate while projects wait in queue—tariff changes, supply chain disruptions, and technology evolution all create repricing risk. Financing commitments typically include sunset clauses that expire if construction doesn't begin within specified windows.

In emerging markets, bankability constraints are particularly acute. India's distribution companies (DISCOMs) face chronic financial stress, making their PPAs less creditworthy. Brazil's regulatory instability—with frequent provisional measures and leadership changes—adds political risk premiums to project finance. For sustainability leads evaluating market entry, understanding these bankability constraints is essential to realistic project planning.

What's Working

FERC Order 2023: Structural Reform in the United States

The Federal Energy Regulatory Commission's Order 2023, issued in July 2023 and implemented throughout 2024, represents the most significant overhaul of generator interconnection procedures in two decades. The reform shifts from a first-come, first-served serial study process to a "first-ready, first-served" cluster study approach that processes interconnection requests in annual groups.

Early results suggest the reform is having an impact. Total US queue capacity declined 12% in 2024—the first reduction in a decade—as stricter financial readiness requirements filtered out speculative projects. Record completions (31 GW solar plus 11 GW battery storage in 2024) combined with 112 GW of withdrawals to reduce the backlog. The reform requires initial study deposits of $55,000-$250,000 depending on project size, with escalating deposits at subsequent study milestones—creating financial incentives for developers to pursue only viable projects.

"Order 2023 has changed the calculus for how we approach interconnection," observes a director of project development at a major independent power producer. "The upfront financial commitments mean we're much more selective about which projects enter the queue. We're seeing fewer speculative entries and more projects with genuine commercial intent."

New York's Accelerated Siting Framework

New York's 2020 siting reform demonstrates what's possible when political will aligns with regulatory redesign. The state consolidated permitting under a single agency with mandated timelines: six months to one year for permit issuance, with a two-year construction goal. Results have been impressive—eight projects averaged less than eight months for permit approval, with only one requiring the full year.

The framework provides a model for emerging markets seeking to accelerate clean energy deployment while maintaining environmental review integrity. Key elements include designated "build-ready" sites with pre-completed environmental analysis, standardised review procedures, and clear timelines with accountability mechanisms.

Texas: Market Liberalisation and Grid Flexibility

Texas added 11.6 GW of solar capacity in 2024—more than any other US state—enabled by a combination of streamlined state-level permitting and a market structure that doesn't require long-term utility PPAs for project viability. ERCOT's merchant market allows projects to sell directly into wholesale markets, bypassing some of the offtaker-related constraints that slow development in regulated markets.

"Texas proves that you can deploy renewables at scale when the regulatory framework is designed for speed rather than control," notes an infrastructure investment analyst. "The trade-off is more merchant risk for developers, but for well-capitalised players, that risk is preferable to multi-year permitting uncertainty."

What's Not Working

Transmission Infrastructure: The Binding Constraint

Even projects that successfully navigate interconnection queues often face binding constraints from inadequate transmission capacity. Interconnection costs have increased 88% over the past decade, reflecting the growing expense of network upgrades required to accommodate new generation. Many projects require transmission expansions that take longer to permit and build than the generation facilities themselves.

The structural problem is jurisdictional: generation projects require local permits and utility interconnection, while transmission lines cross multiple jurisdictions with separate permitting requirements. A solar project might complete permitting in eighteen months, only to discover that the transmission upgrade enabling its grid connection requires seven years of regulatory approvals.

"We've seen multiple projects reach the finish line on everything within their control—permits, equipment procurement, construction financing—only to be told that the transmission upgrade they need won't be complete for another five years," explains a project finance attorney specialising in renewable energy. "The entire development timeline is hostage to transmission planning processes that move at a completely different pace."

Local Opposition: The Rising Barrier

Local restrictions on renewable energy development have proliferated despite broad public support for clean energy transition. The pattern typically involves well-organised opposition movements that leverage local zoning authority to impose setback requirements, height restrictions, or outright bans that make commercial-scale development uneconomic.

Community opposition causes average delays of 11 months for solar projects and 14 months for wind projects. More significantly, local opposition accounts for the largest share of project cancellations—exceeding federal permitting as a barrier. States have begun responding with preemption legislation, but the political dynamics remain contentious.

Emerging Market Offtaker Risk

For sustainability leads evaluating emerging market opportunities, offtaker creditworthiness represents perhaps the most significant bankability constraint. India's 40 GW of stalled capacity reflects not technical or permitting barriers, but the inability of financially stressed distribution companies to sign and honour power purchase agreements.

In Brazil, regulatory instability compounds offtaker risk. Multiple provisional measures moving through Congress create continuous uncertainty about tariff structures, subsidy frameworks, and market rules. New renewable concessions no longer receive transmission and distribution tariff discounts that fossil sources retain—a policy inconsistency that undermines clean energy competitiveness.

"Emerging markets often have excellent renewable resources and genuine political commitment to clean energy," observes an infrastructure fund manager with experience across Latin America and Southeast Asia. "But project finance requires predictable revenue streams over 15-20 years. When you can't trust that today's regulatory framework will exist in five years, the risk premium makes projects unfinanceable."

Action Checklist

  1. Map jurisdictional complexity before site selection: Before committing to project locations, analyse the full permitting landscape including federal, state, and local requirements. Engage with local planning departments early to identify potential opposition and zoning constraints that could derail projects after significant capital commitment.

  2. Model interconnection timelines conservatively: Assume five-year queue wait times for US projects and adjust financial models accordingly. Factor interconnection cost escalation into project economics—costs have increased 88% over the past decade and may continue rising as grid upgrade requirements grow.

  3. Structure offtake agreements with timeline flexibility: Negotiate PPAs with extension provisions that account for permitting and interconnection delays. Include price adjustment mechanisms that reflect equipment cost changes during extended development periods.

  4. Build relationships with grid operators early: Engage with transmission providers during site selection, not after. Understanding upgrade requirements and cluster study timing can inform project sequencing and prevent queue position losses.

  5. Evaluate state-level permitting reforms: States like New York, California, and Massachusetts have implemented accelerated siting frameworks that significantly reduce permitting timelines. Prioritise markets with demonstrated reform track records over markets with theoretical resource advantages but unproven regulatory pathways.

  6. Assess emerging market offtaker creditworthiness rigorously: For projects in India, Brazil, Indonesia, and other emerging markets, conduct detailed due diligence on distribution company financial health. Consider credit enhancement structures, sovereign guarantees, or multilateral development bank support to mitigate offtaker risk.

  7. Track policy developments actively: Federal reforms like FERC Order 2023 and proposed legislation like the Energy Permitting Reform Act create opportunities for developers who understand implementation timelines. Maintain active engagement with industry associations and regulatory proceedings.

  8. Build community engagement into project timelines: Local opposition has become a leading cause of project delays and cancellations. Budget for meaningful community engagement, benefit-sharing arrangements, and local hiring commitments that build project support rather than treating community relations as an afterthought.

FAQ

Q: How long should sustainability leads expect clean energy projects to take from conception to commercial operation in current market conditions?

A: In the United States, assume 5-7 years for utility-scale solar and wind projects, with transmission projects potentially requiring 10-15 years or longer. The median interconnection queue wait time is now five years, to which you must add 1-2 years for permitting and 1-2 years for construction. Projects in states with accelerated siting frameworks (New York, California) may complete faster, while projects requiring significant transmission upgrades may take substantially longer. For emerging markets, timelines vary significantly by jurisdiction, but India and Brazil projects typically face 3-5 year development cycles when accounting for offtake agreement negotiation and grid connection. The critical planning insight is that technology deployment is no longer the binding constraint—institutional processes now determine project timelines.

Q: What does FERC Order 2023 mean for projects currently in interconnection queues, and how should developers adjust their strategies?

A: FERC Order 2023 fundamentally changes the interconnection process from first-come, first-served to first-ready, first-served cluster studies. For existing queue projects, transmission providers are implementing transitional processes that allow withdrawal without penalty or continuation under modified procedures. The reform requires substantially higher upfront deposits ($55,000-$250,000 initially, escalating to 5-10% of network upgrade costs at later stages), which filters out speculative projects but increases committed capital for serious developers. Strategically, developers should be more selective about queue entries, conduct more thorough due diligence before requesting interconnection, and ensure projects have genuine commercial viability before committing financial deposits. The reform rewards well-capitalised developers with shovel-ready projects and disadvantages those who previously used queue positions as options while developing commercial arrangements.

Q: What are the most effective strategies for navigating local opposition to clean energy projects?

A: Practitioners consistently emphasise early, genuine community engagement rather than after-the-fact mitigation. Successful strategies include hosting community benefits agreements that provide direct economic returns (property tax equivalents, community funds, local hiring commitments), engaging local government officials before public announcements, and designing projects to address specific community concerns (setbacks, visual screening, noise mitigation). Agricultural communities often respond positively to agrivoltaics arrangements that allow continued farming beneath solar panels. The timing matters enormously—projects that announce without prior community engagement face 14 months of average delays for wind and 11 months for solar. Projects that invest in relationship-building before permitting applications typically face less organised opposition and faster approval timelines.

Q: How should sustainability leads evaluate emerging market opportunities given the permitting and bankability challenges described?

A: Emerging market evaluation should prioritise regulatory stability and offtaker creditworthiness over raw resource potential. India offers excellent solar resources but requires careful assessment of state-level DISCOM financial health and Power Sale Agreement execution timelines. Brazil's regulatory volatility—with frequent provisional measures and policy reversals—demands either shorter investment horizons or credit enhancement structures that mitigate regulatory change risk. For markets with weak offtaker credit, consider structures involving multilateral development bank guarantees (World Bank, IFC, AIIB), sovereign guarantees, or direct corporate PPAs with multinational offtakers who bring investment-grade credit regardless of local utility conditions. The practitioners we interviewed consistently advised treating regulatory and offtaker risk analysis with the same rigour as technical and resource assessment—and being willing to walk away from attractive resource sites when institutional fundamentals are inadequate.

Q: What policy reforms would most significantly accelerate clean energy deployment, and what is their likelihood of enactment?

A: Practitioners consistently identify transmission permitting reform as the highest-impact intervention. The proposed Energy Permitting Reform Act of 2024, which advanced from committee but did not pass, included 150-day decision deadlines, enhanced FERC authority over interstate transmission, and categorical exclusions for low-impact projects. If enacted in some form during the current Congress, such reforms could reduce project timelines by 6-12 months and enable the transmission buildout required to connect renewable generation to load centres. At the state level, single-agency permitting frameworks (like New York's accelerated siting process) have demonstrated ability to cut approval timelines by 50% or more. The likelihood of comprehensive federal reform remains uncertain given political dynamics, but state-level reforms continue advancing in both Democratic and Republican-led states that recognise clean energy's economic development potential.

Sources

The clean energy transition's binding constraint has shifted from technology cost to institutional capacity. The $369 billion Inflation Reduction Act demonstrated that capital is available; the 2,290 GW sitting in US interconnection queues demonstrates that projects are ready. What remains is the harder work of reforming permitting processes, building transmission infrastructure, and creating regulatory frameworks that match the pace of climate necessity. For sustainability leads in emerging markets, success requires understanding these institutional realities with the same rigour applied to technology and finance—and building project strategies that account for permitting timelines measured in years, not months.
