Little (ADL) explores the transformation of global electricity systems in the face of rapid electrification, renewable energy growth, and digitalization. It emphasizes the increasing complexity and variability of electricity systems, driven by rising demand and the dominance of variable renewable energy (VRE) sources like solar and wind. The report outlines strategies to maintain reliability, affordability, and resilience in power systems as they transition from traditional models to more flexible, digitally integrated systems. --- ## Main Points ### 1. Electricity Demand & Supply Outlook - **Rising Demand**: Global electricity demand is expected to grow by 40%-55% by 2035 and could potentially double by mid-century. - **Geographical Shift**: Growth is concentrated in emerging markets, which will account for over 75% of incremental demand by 2035. Advanced economies, while growing slowly, face localized adequacy stress due to concentrated loads like data centers and EV charging. - **Supply Mix**: VRE (solar and wind) will dominate new supply additions, reaching 35%-40% of total supply by 2035, up from 15% in 2024. Fossil fuels, particularly gas, will remain significant in the near term, while nuclear is gaining strategic attention in some regions. - **Operability Challenge**: The focus is shifting from simply meeting energy demand to managing system operability, including grid flexibility, peak load management, and dispatchable energy sources. ### 2. Rising Electricity System Imbalances - **Three Types of Imbalance**: - **Temporal**: Increased variability in supply and demand, leading to sharper ramps, evening peaks, and surplus generation. Flexibility needs are expected to rise 2–7 times by 2035. - **Spatial**: Generation and demand are increasingly misaligned, straining transmission capacity. This results in congestion, curtailment, and long waiting times for grid connections. - **Stability**: Declining synchronous inertia in high-renewable systems increases the risk of outages and cascading failures, as seen in the 2025 Iberian Peninsula blackout. - **Market Archetypes**: Five distinct market types are identified to guide targeted interventions: - VRE-Frontier - Grid-Bottleneck - Transition-Scaling - Adequacy-Stressed - Resource-Rich --- ## Key Solutions for the Next Decade - **Flexibility Over Supply Expansion**: The report advocates for a shift from supply expansion to enhancing flexibility and deliverability. - **Four-Step Strategy**: 1. **Quick Wins**: Use demand response, grid-enhancing technologies, and digital tools to stabilize operations. 2. **Institutional Plays**: Reform markets and scale VPPs, V2G, and industrial demand response to institutionalize flexibility. 3. **Capital Plays**: Expand utility-scale storage, deploy firm low-carbon capacity, and enhance technical inertia. 4. **Structural Overhauls**: Focus on regional grid expansion, interconnections, and sector coupling. - **Investment Needs**: Significant investment is required to achieve a flexible buffer model, with the US and Europe needing to double grid investment by 2030, reaching \$1 trillion by 2030 and \$3.5 trillion by 2035. --- ## Electricity Systems Beyond 2035 - **Resilience as Priority**: System resilience will depend on the parallel scaling of technical and institutional solutions. - **Four Key Needs**: 1. **Multiday and Seasonal Balancing** 2. **Low-Carbon Dispatchable Capacity** 3. **Network Deliverability** 4. **Digital Orchestration at Scale** - **Uncertainties**: Five shaping factors (demand, grid capability, supply chains, geopolitics, climate resilience) will influence future electricity system development. - **Scenarios**: - **Managed Scarcity**: Demand outpaces infrastructure, leading to persistent constraints. - **Stranded Build**: Overinvestment in infrastructure relative to demand. - **Security First**: Reliability concerns dominate planning, potentially slowing decarbonization. - **Electro-Abundance**: Synchronized growth in demand and infrastructure, enabling stable deep electrification. --- ## Strategic Recommendations 1. **Grid for 2050**: Plan and invest in grid infrastructure aligned with renewable zones, electrified industries, and urban growth. 2. **Embed Flexibility**: Scale storage, demand response, and digital orchestration to meet rising flexibility needs. 3. **Digital Infrastructure**: Institutionalize digital solutions like advanced forecasting, real-time telemetry, and cybersecurity. 4. **Digital Grid Capabilities**: Strengthen regulatory, planning, and project execution capabilities to industrialize grid development. 5. **Strategic Insurance**: Diversify supply chains, preserve seasonal adequacy, and harden infrastructure against climate and cyber risks. 6. **Adaptive Governance**: Implement governance based on measurable stress indicators (congestion, price volatility, etc.) to enable timely course corrections. --- ## Key Takeaways - **Grid Investment**: \$3–\$4 trillion in grid investment is needed by 2030 to keep pace with electrification and climate goals. - **Flexibility Growth**: Flexibility needs are expected to grow 2–3 times faster than demand in regions like the US and Europe. - **Reliability Costs**: In renewable-heavy markets, reliability costs may exceed energy costs due to system imbalances. - **Software-Defined Grid**: By 2035, grids will increasingly rely on digital orchestration rather than centralized dispatch. - **System Stress**: Temporal, spatial, and stability imbalances are growing, requiring parallel investment in grids, flexibility, and resilience. --- ## Conclusion The report highlights that the global electricity system is undergoing a profound transformation. The challenges of managing system imbalances will require a coordinated approach involving investment, innovation, and institutional reform. If infrastructure, capital, and institutional capacity can be scaled in parallel with demand and renewable growth, the system can evolve toward abundance and stability. Otherwise, risks of scarcity, stranded assets, and system fragility will increase, with severe implications for both business and society.
