Regulating for Resilience: Modern Grid Rules to Enable Investment, Innovation and Social License

Regulation is fast becoming one of the most strategic levers for Latin America and the Caribbean’s (LAC) energy future—not just a technical box-ticking exercise. The Inter-American Development Bank (IDB)’s new technical note, “Unlocking the Grid: How to Ensure Reliable and Sustainable Energy in Latin America and the Caribbean” (Alarcón & Quirós-Tortós, 2025), places modern, resilient regulation at the heart of its roadmap for transforming transmission systems.

This article in the Dawgen Decodes series—“Regulating for Resilience: Modern Grid Rules to Enable Investment, Innovation and Social License”—unpacks those ideas from a Caribbean and advisory perspective: how regulators, policymakers, utilities and investors can reshape grid rules to unlock capital, enable innovation and earn social license, while staying aligned with IDB recommendations.

1. Why “regulating for resilience” is now a strategic imperative

The IDB report is blunt: transmission networks are no longer a passive conveyor of electrons; they are a strategic backbone that will determine whether LAC can integrate renewables, ensure reliability, and sustain economic and social development.

Yet the report finds that:

• Planning, regulation, financing, permitting and technology are still fragmented silos.

• Existing regulatory models often fail to recognize the grid’s functional attributes—stability, reliability, resilience—and do not systematically incentivize efficiency or innovation.

• Regulatory incoherence contributes directly to under-investment in transmission, delays in project execution and difficulty mobilizing private capital.

In response, the IDB proposes a transformation agenda organized around five pillars—planning, regulation, financing, permitting & implementation, and technological innovation—with regulation acting as the “translator” that converts planning visions into bankable projects and credible incentives.

For the Caribbean, where small island systems face high climate risk, concentrated utilities and tight fiscal space, this “regulation-as-strategy” message is particularly salient.

2. A region of many models: understanding LAC’s regulatory diversity

One of the strengths of the IDB study is its systematic mapping of LAC’s regulatory landscape along eight key dimensions:

1. Degree of separation between generation, transmission and distribution

2. Existence of an independent transmission operator

3. Ownership of transmission assets

4. Level of private participation in transmission

5. Technical autonomy of the regulator

6. Transmission remuneration model

7. Expansion model (who plans and how projects are executed)

8. Grid access regime (open, limited, or discretionary)

On this basis, the report identifies several regulatory archetypes:

• Liberalized markets with high private participation (e.g. Brazil, Chile, Peru)

• Mixed models with independent state-owned operators (e.g. Colombia, Uruguay)

• State-owned systems with limited formal independence (e.g. Ecuador, Nicaragua)

• Centralized national public enterprise models

• Island systems with dominant operators, such as Jamaica, where a private utility operates transmission and distribution under an integrated contract.

For **smaller or integrated systems—such as Costa Rica or Jamaica—the IDB explicitly recommends scalable, low-cost solutions (conductor upgrades, storage, flow control technologies) within regulatory frameworks that protect both system efficiency and the financial stability of public utilities.

Implication for policy makers and regulators:
There is no single “perfect” model to copy; instead, each country must modernize from its own starting point, but in line with common principles: risk allocation clarity, regulatory credibility, incentives for resilience and innovation, and alignment with planning.

3. Regulation as the bridge from plans to power lines

The IDB is very clear that planning and regulation are complementary, not sequential functions:

• Planning defines infrastructure needs and territorial priorities.

• Regulation transforms those needs into economic signals, contracts, and remuneration rules that make projects bankable.

Effective regulation:

• Explicitly allocates risk among investors, operators, end users and the State.

• Defines the contractual and tariff conditions under which planned projects are tendered, financed and built.

• Acts as a structural link between long-term plans and actual construction.

The report highlights good practice examples:

• Brazil – The Energy Research Company (EPE) prepares ten-year plans that feed directly into ANEEL’s competitive transmission auctions, with clear risk allocation and stable regulated revenues.

• Colombia – Strong coordination among the planning unit UPME, the regulator CREG and the system operator XM ensures that expansion plans become the basis for tenders and tariff decisions.

• United Kingdom – Network Options Assessments by the system operator are linked to the RIIO (Revenue = Incentives + Innovation + Outputs) regulatory model, which connects planning decisions to performance-based remuneration and innovation incentives.

The IDB suggests institutional mechanisms—binding plans, joint project evaluation, interinstitutional committees, public expansion schedules—to formalize this coordination.

For Caribbean regulators and ministries, the lesson is straightforward: if planning outputs are not hard-wired into regulatory processes, they remain aspirational rather than executable.

4. Modern remuneration frameworks: from “cost of wires” to “value of services”

Traditional transmission regulation in LAC has relied heavily on annual revenue or cost-plus schemes focused on asset recovery. These models provide financial stability, but they can:

• Over-reward capital-intensive solutions

• Under-incentivize innovative or non-wires alternatives

• Fail to value performance outcomes like resilience or flexibility.

The IDB notes several international shifts that LAC can adapt:

1. Hybrid revenue + performance models

   • Countries such as Chile and Colombia are combining base allowed revenues with bonuses/penalties for reliability, availability and service quality, better aligning operator incentives with user outcomes.

2. Performance-based frameworks (RIIO, etc.)

   • The UK’s RIIO model explicitly links revenues to outputs, innovation and measurable KPIs (SAIDI, SAIFI, availability).

3. TOTEX (Total Expenditure) approaches

   • By remunerating optimised total cost rather than separating CAPEX and OPEX, TOTEX models encourage efficient lifecycle decisions and support non-traditional solutions like grid-enhancing technologies (GETs) and storage.

4. Tariffs that value new grid functions

   • As renewables, distributed generation and storage increase, the grid delivers congestion management, flexibility, digital interoperability and resilience—services that current tariffs often fail to price explicitly.

The IDB also stresses that tariff harmonization across countries is crucial for regional integration initiatives (e.g. SIEPAC). Without it, interconnections remain under-utilized and investors face conflicting signals.

For Caribbean regulators, modernizing remuneration frameworks is not just a technical upgrade—it is a precondition for innovation, resilience and cross-border cooperation.

5. Regulation to unlock private capital at scale

The investment gap highlighted by the IDB is stark:

• LAC plans to build over 150,000 km of new transmission lines by 2035, representing up to a 40% expansion of current networks.

• Actual annual transmission investment (≈USD 3.3 billion in 2022) is far below what is required. Projections suggest investment must at least double (≈USD 6 billion) or even quadruple (up to USD 14 billion annually by 2030) under more ambitious climate scenarios.

• Public budgets alone cannot close this gap, especially with constrained fiscal space and high public debt in many countries.

The report emphasizes that regulation is the gateway for private capital:

• It defines revenue rights, risk allocation, contract structure and payment traceability—everything financiers need to evaluate bankability.

• It enables a menu of participation and financing instruments, including:

  • BOOT and BOO concessions with regulated annual revenue

  • Public–private partnerships (PPPs)

  • Trusts with payment prioritization

  • Regulated leasing models

  • Asset recycling

  • Transmission rights and contingent rights

  • Green and thematic bonds, green taxonomies

  • Multilateral guarantees and contingent bonds

  • Cap-and-floor schemes for interconnections.

For Caribbean island systems, where project sizes are modest but strategic, tailored combinations of these instruments—backed by credible regulation and multilateral support—can attract regional and international investors without overburdening sovereign balance sheets.

6. IDB’s regulatory roadmap: key recommendations

Section 3.5 of the IDB report sets out regulatory recommendations to enable investment and resilience, grouped into thematic blocks. From a Dawgen Global perspective, these can be translated into a practical reform agenda.

6.1 Ensuring a functional, resilient and innovative design

The IDB calls for regulatory frameworks that shift from “infrastructure” to “services”—prioritising what the grid does (reliability, resilience, flexibility) rather than just what it is (lines, substations).

Key actions include:

• Making resilience and innovation structural principles of regulation, not afterthoughts.

• Explicitly recognizing investments in:

  • Protection against extreme climate events and cyberattacks

  • Sensors, automation, smart grids and advanced conductors

  • Grid-enhancing technologies that relieve congestion or increase transfer capacity.

• Updating asset catalogs, depreciation rules and remuneration schemes so these new technologies are not disadvantaged versus traditional hardware.

The IDB also advocates for adaptive, learning-oriented frameworks:

• Periodic, mid-term review cycles

• Regulatory sandboxes and pilot schemes for emerging technologies

• Performance-based evaluation criteria that can be refined over time.

6.2 Strengthening regulatory institutions and capacities

Modern rules are meaningless without institutions capable of enforcing them. The report argues that regulators need:

• Functional autonomy, budget stability and technical capacity

• Access to advanced analytical tools and continuous training

• Stable staffing, with reduced political interference and turnover

• Strong supervision systems to verify contractual, technical and financial compliance

• Transparent regulatory governance with:

  • Published methodologies

  • Formal consultation and appeal mechanisms

  • Systematic publication of decisions and their technical basis.

For many Caribbean regulators—often small teams with broad mandates—this implies a deliberate capacity-building agenda, potentially supported by regional cooperation and multilateral partners.

6.3 Aligning regulation, planning and sustainability

The IDB urges countries to integrate social and environmental sustainability into regulatory design from the outset, not only at the permitting stage.

This means:

• Incentivising early community consultation and robust compensation mechanisms

• Embedding environmental criteria into tariff and investment approval processes

• Encouraging solutions such as energy corridors, shared lines or undergrounding where technically and economically feasible

• Supporting regional regulatory harmonization to make interconnections technically and financially viable, particularly for initiatives linking the Caribbean to continental systems.

6.4 Managing risks and adapting frameworks to context

Finally, the IDB emphasizes explicit risk recognition and differentiated frameworks:

• Mapping climatic, social, regulatory and financial risks, and using tools such as guarantees, trusts, insurance and automatic income adjustments to manage them.

• Designing scalable regulatory regimes that:

  • Use simpler, more standardized contractual approaches in fragile institutional contexts

  • Allow advanced models (performance-based, TOTEX, complex PPPs) where capacity is stronger

  • Offer special rules for regional interconnections and pilot projects.

The overarching message: don’t copy-paste foreign models. Build adaptive, results-oriented regulation that fits local constraints while meeting global expectations for reliability, resilience and sustainability.

7. What this means for the Caribbean

For Caribbean countries—including Jamaica, where the IDB classifies the system as having partial unbundling, a private transmission operator and limited access—these recommendations translate into some concrete priorities:

1. Resilience-focused regulation

   • Incentives for grid hardening, redundancy and rapid recovery in the face of hurricanes and tropical storms

   • Mechanisms to value resilience investments within tariffs and performance frameworks.

2. Innovation within small systems

   • Regulatory recognition of storage, advanced conductors, dynamic line rating and other GETs that can deliver big benefits without full-scale network rebuilds.

3. Quality-of-service and social licence

   • Clear standards for reliability and quality, with transparent reporting and community engagement

   • Regulatory frameworks that anticipate local concerns and enable benefit sharing.

4. Attracting fit-for-purpose capital

   • Small but strategic projects may suit combinations of PPPs, regulated leasing, green bonds and multilateral guarantees—provided the regulatory foundation is credible.

For governments and utilities in the Caribbean, the IDB report offers both a diagnostic and a menu of tools. The challenge—and opportunity—is to tailor these to local realities while retaining investor confidence.
