When Clean Power Isn’t Enough: The Grid, Policy and Market Fixes Energy Transitions Need

The next climate breakthrough isn’t a turbine—it’s the system around it

The world is installing solar panels and wind turbines at record pace, yet emissions aren’t falling everywhere. In early 2026, China’s CO2 output rose about 2% even as it added unprecedented clean capacity. Indonesia’s high-profile Just Energy Transition Partnership (JETP) is wobbling after the government reversed plans to retire a linchpin coal plant. And in capital markets, a leading Canadian investor watchdog shut down, concluding that shareholder activism has hit its limits in forcing corporate decarbonization.

These are not failures of solar or wind. They are failures of systems—grids, storage, market design, policy continuity, and demand-side integration. The lesson from recent headlines is clear: climate progress now depends less on deploying more clean megawatts than on building the connective tissue that lets those megawatts displace fossil fuels hour by hour, place by place.

China’s paradox: record renewables, rising emissions

China’s buildout of clean power is staggering, yet a growing share of that power is not used. In the first quarter of 2026, national CO2 emissions climbed by roughly 2%, according to independent analysis, even as wind and solar capacity surged to new highs. The culprit: curtailment—the forced reduction of renewable output because grids, markets, or flexible resources can’t absorb it.

Why curtailment is rising:

• Grid bottlenecks: Wind and solar are concentrated in resource-rich northern and western provinces, while demand clusters on the eastern seaboard. Transmission additions have lagged project development.
• Inflexible thermal fleets: Legacy coal plants, still remunerated in ways that favor baseload operation, don’t ramp down readily to make room for variable renewables.
• Market design gaps: Limited real-time price signals and ancillary service markets constrain the monetization of flexibility (storage, demand response, fast-ramping plants), making renewables the path of least resistance for curtailment.
• Volatility: Weather-driven swings and episodic demand spikes raise the value of flexibility that isn’t yet widely deployed.

The fix is systemic, not just additive. China’s next ton of avoided CO2 depends on accelerating ultra-high-voltage (UHV) transmission, scaling storage (4–8 hours near-term, longer-duration for seasonal balancing), making coal fleets flexible with performance-based pay, and expanding regional spot markets that pay for fast response and location value. Curtailment should be a KPI to beat, not a cost of doing business.

Indonesia’s JETP stumble: when finance meets policy reality

Indonesia’s $20 billion JETP—touted as a model for coal-to-clean transitions—has hit turbulence after the government abandoned plans to shut a major coal plant central to the deal. The reversal exposes frictions that many emerging economies face:

• Coal’s deep entanglement: Coal supplies roughly 60% of Indonesia’s power generation, with long-term take-or-pay contracts and captive plants serving energy-intensive industries (notably metals processing).
• Grid and planning constraints: Rapidly replacing coal requires not only new renewables but transmission reinforcements and storage to maintain reliability on the Java-Bali and Sumatra systems.
• Social and fiscal risk: Early retirement can strand assets and jobs without credible compensation mechanisms, dedicated transition funds, and tariff reform to protect low-income consumers.

The JETP lesson is not that transition partnerships fail, but that they must be engineered around system needs, utility balance sheets, and binding policy milestones.

What would make deals like JETP investable and durable:

• Align with national power plans and utility P&Ls: Retire the most expensive and inflexible units first, and refinance remaining coal into pay-for-flex contracts that support renewable integration.
• Earmark concessional capital for grids and storage: Transmission and firming capacity should be front-loaded; they unlock multiples of private capital for renewables.
• Hardwire milestones: Link disbursements to specific asset retirements, interconnection projects, and market reforms, with transparent progress tracking.
• Protect people: Fund worker redeployment, local tax backfills, and targeted bill support to preserve political legitimacy.

The limits of shareholder activism—and what replaces it

Investors for Paris Compliance, a Canadian group known for pushing banks and corporates on climate plans, closed its doors in June, citing the tightening limits of shareholder activism. It’s not alone: across major markets, support for environmental shareholder resolutions has trended down since 2022 amid political backlash and narrow interpretations of fiduciary duty.

Corporate engagement remains useful, but it cannot substitute for policy. Voluntary pressure can polish disclosures; it rarely rewires power systems. What moves steel in the ground are procurement mandates, clear market rules, and public investment in shared infrastructure.

If activism 1.0 was about proxy votes, 2.0 must be about policy design—investors mobilizing behind permitting reform, modernized grid tariffs, capacity mechanisms that reward flexibility, and standards that de-risk demand-side participation.

Policy design can accelerate—or stall—decarbonization

Two policy arenas this month underline how rules shape real-world outcomes.

• Bonn climate talks (SB64): Negotiators are working toward decisions that will steer capital this decade—finalizing the integrity and accounting of Article 6 carbon markets; shaping a new collective finance goal that could prioritize transmission and storage in the Global South; and operationalizing just transition work programs. These aren’t abstractions: whether a renewable developer in Indonesia can bank a storage project, or a utility in Kenya can finance a regional interconnector, hinges on predictable rules and concessional finance frameworks.

• The UK’s seventh carbon budget: The Labour government’s plan sets a pathway to roughly 87% emissions cuts below 1990 levels by the early 2040s, with an estimated £865bn in economic benefits, according to recent analysis. That scale of benefit is only plausible because the budget is paired with concrete delivery mechanisms: contracts for difference for low-cost clean generation, grid buildout and planning reform, heat pump and insulation programs to shift and shrink demand, and industrial strategies for clean hydrogen and CCS in hard-to-abate sectors. The broader point: policy continuity and credible delivery institutions crowd in private investment.

A systems-first playbook for the next emissions drop

Clean power additions are necessary. To make them sufficient, countries and companies need a stack of reforms that prioritize integration and flexibility. Five no-regrets moves stand out:

1. Build grids as a climate asset

• Treat transmission like a public good with accelerated permitting, anticipatory planning, and cost recovery that recognizes system value.
• Expand regional interconnections to smooth variability and share capacity reserves.
• Publish curtailment maps and interconnection queues to guide siting and prioritization.

2. Procure flexibility, not just energy

• Run auctions for storage (by duration classes) and demand response, with contracts that value capacity, ramping, and fast frequency response.
• Make thermal fleets earn flexibility premiums by meeting ramp-rate and minimum-stable-load standards.

3. Modernize market design

• Move from annual/administrative dispatch to day-ahead and real-time markets with locational pricing where feasible.
• Create robust ancillary service products and scarcity pricing that rewards availability during net-peak hours.
• Enable aggregated demand-side resources to bid like generators, with measurement and verification rules that are simple and bankable.

4. Anchor transitions in durable policy

• Pair coal retirement with securitization or concessional refinancing to avoid utility insolvency; link payouts to verified emissions reductions.
• Maintain technology-neutral investment frameworks (e.g., CfDs, tax credits) with predictable timelines and auction calendars.
• Use public balance sheets for shared infrastructure (grids, ports, CO2 pipelines) that unlock private capital at scale.

5. Make demand a first-class resource

• Deploy smart tariffs (time-of-use, critical-peak) and default automation for EV charging and heat pumps to shift load into renewable-rich hours.
• Incentivize industrial flexibility—thermal storage, process rescheduling, green hydrogen electrolysis that soaks up midday surplus.
• Benchmark participation: set targets for a minimum share of peak load to be flexible by 2030 and 2035.

What to measure next

Managing what we measure will separate leaders from laggards. Beyond tons of CO2, track:

• Curtailment rate (by region, by technology)
• Interconnection queue time (median months to energization)
• Flexible capacity share (% of peak provided by storage and demand response)
• Coal fleet flexibility (average minimum stable load, ramp rate)
• Policy credibility (share of announced retirements met on time; auction volumes delivered vs. planned)

The takeaway

The energy transition’s early wins came from making clean energy cheap. The next wins will come from making clean energy useful—every hour, in every region. China’s growing curtailment despite record build, Indonesia’s JETP detour, and the retreat of shareholder activism all point to the same conclusion: decarbonization is now a systems problem.

Bonn’s rulebooks and the UK’s budget architecture show how policy can clear a path. With grids that reach, markets that value flexibility, storage that soaks up surplus, and demand that moves with the wind and sun, clean power can finally do what it’s meant to: push fossil fuels off the system for good.
