Five Layers of Grid Flexibility and the Startups Building Them

In our recent analysis, Where the Grid Gets Flexible, we explored how grid flexibility is emerging across multiple layers of the energy system. From demand response and energy storage to orchestration software and network optimization, flexibility is becoming one of the defining investment and infrastructure themes of the energy transition.

But this transformation is not being driven by utilities alone.

A new generation of startups is building the software, storage systems, and digital infrastructure enabling the grid to respond more dynamically to volatility, congestion, and changing demand patterns.

Flexibility is emerging across every layer of the electricity system – from demand response and storage to orchestration software and transmission optimization. Below, we look at startups building the infrastructure behind a more dynamic and responsive grid.

Demand-side flexibility

As electricity demand becomes increasingly volatile, driven by EV adoption, electrified heating, and data center growth, flexible demand is becoming one of the fastest ways to balance the grid without building entirely new infrastructure.

This layer includes virtual power plants (VPPs), building energy optimization, industrial demand response, and customer participation platforms.

Startups to watch

1. Embue – developing building intelligence software that optimizes HVAC systems and commercial building energy consumption in real time.
2. Virtual Peaker – enabling utilities to orchestrate distributed energy resources and demand response programs through virtual power plant software.
3. Skye Energy – providing AI-based optimization and flexibility management for commercial and industrial energy assets.
4. Emerald AI – focused on enabling data center flexibility by dynamically adjusting computing workloads based on grid conditions and renewable availability.
5. GridBeyond – delivering AI-powered energy optimization and industrial flexibility services across power markets.

Storage-enabled flexibility

While lithium-ion batteries dominate near-term deployments, a broader range of storage technologies is emerging to address duration, safety, material supply chains, and cost challenges.

Startups to watch

1. TheStorage – developing thermal energy storage systems designed to provide flexible heat and energy balancing capabilities.
2. Orenda Power – building distributed storage and resiliency solutions aimed at improving grid stability and local flexibility.
3. Photoncycle – developing hydrogen-based seasonal energy storage solutions designed for long-duration flexibility.
4. Qnetic – advancing flywheel-based energy storage systems for long-duration and high-cycle grid applications.
5. Exergy3 – focused on advanced thermal energy storage systems for industrial and grid-scale flexibility applications.

Supply-side flexibility

This layer enables operators to optimize how flexible power assets respond to changing grid conditions.

These solutions are becoming increasingly important as renewable generation introduces higher variability into electricity markets.

Startups to watch

1. Innovus Power – developing distributed power generation and resilient energy infrastructure solutions.
2. Smart Grid Solutions (SGRIDS) – enabling intelligent management and dispatch optimization of distributed energy assets.
3. Aigent Energy – building AI-driven software to optimize energy generation dispatch and power market participation.

Grid flexibility coordination

This layer acts as the orchestration and market interface connecting distributed assets, utilities, aggregators, and grid operators. These platforms help manage flexibility across multiple markets, dispatch resources in real time, and optimize grid balancing decisions.

Startups to watch

1. DG Matrix – developing solid-state power electronics designed to improve energy management and distributed grid coordination.
2. DERapi – providing APIs and integration infrastructure for distributed energy resource management and interoperability.
3. Capalo AI – using AI-driven forecasting and optimization to aggregate and trade flexible energy assets.
4. Fuse Energy – building vertically integrated energy software and optimization infrastructure for flexible energy systems.
5. Tibo Energy – developing AI-enabled energy management platforms for distributed flexibility orchestration.

Network-side flexibility

As congestion and interconnection bottlenecks become more severe globally, network-side flexibility is increasingly attracting attention from grid operators and investors alike.

Startups to watch

1. Infravision – modernizing transmission infrastructure deployment through robotics and advanced construction technologies.
2. Prisma Photonics – using fiber-sensing technology to monitor transmission networks and improve grid visibility in real time.
3. GridAstra – focused on software-driven optimization of transmission and distribution infrastructure.
4. Gridraven – developing dynamic line rating technologies that increase transmission capacity using real-time conditions.
5. Enline – building digital monitoring and analytics solutions for transmission infrastructure optimization.

As utilities, hyperscalers, and industrial operators contend with rising volatility, grid flexibility is becoming a core design principle of modern power systems rather than an optional capability.

What’s becoming clear is that no single layer solves flexibility on its own, it emerges from coordination across demand, storage, generation, and the network itself. The real shift is not just technological, but systemic.
