Many building loads, such as space heating, cooling and water heating, can respond to price signals or automated controls when equipped with controllable technologies, giving the sector large long-term DR potential. Currently, the industrial sector provides the largest share of demand response across all sectors, with around 75 GW of utilisation. Finally, markets with high shares of solar and wind are challenged by periods of overabundance, when supply has the potential to exceed demand for grid electricity, necessitating operators to implement measures to balance the system. As the global energy landscape shifts toward decarbonisation and renewable energy, energy flexibility has become crucial for ensuring a stable, efficient, and cost-effective energy system. Regulatory support and market structures that facilitate the integration of residential flexibilities into electricity markets are the key tosuccess, but are not yet in place in all markets across Europe.
However, globally, according to the ETI 2025 report, scores for electricity system flexibility declined 1.3%. Overall, as underlying measures of system performance, there have been improvements in security, equity, and sustainability over the past decade. However, new infrastructure planning takes between 5-10 years, Wood Mackenzie cautions – and data centres will need access to more energy rapidly. Typically, rising demand for energy has been met by adding more power generation capacity. The International Energy Agency (IEA) predicts that electricity use from AI data centres will more than quadruple by 2030, and the impact of this surge will be particularly pronounced locally in the world’s leading data centre hubs. This was due to heatwaves, growing electrification, industrial expansion and the growth of data centres to accommodate energy-hungry generative AI processing.
- At the individual site level, energy flexibility is the ability to reduce energy use or shift that usage to different times of day in response to external factors, such as requests by the grid operator.
- However, the landscape is evolving, and with a rising number of smaller-scale prosumers and decentralized energy assets, we at gridX expect a shift towards incorporating flexibility from more diverse sources.
- Ensuring supply-demand balance during these steep net load changes is a growing challenge in much of the United States, as existing supply resources are not all able to instantaneously re-adjust.
- However, globally, according to the ETI 2025 report, scores for electricity system flexibility declined 1.3%.
- Different options are addressed, from increasing control of output from small solar installations, to higher battery deployment, to refining price signals, including offering free electricity to customers.
Theoretical potential encompasses all electricity demand that could, in principle, be shifted or reduced, assuming full deployment of https://thecolumbianews.net/why-electric-boats-are-the-future-of-sustainable-boating.html enabling technologies and subject only to physical and end‑use service constraints. Currently utilised demand response refers to the capacity already active in markets or programmes. Similarly, residential air conditioning (AC) contributes around 600 GW, yet flexible demand response from AC loads remains marginal. In exchange, DR plans offer financial incentives, typically through contractual arrangements or participation in programmes with utilities, aggregators or system operators, or by direct participation in power markets in the case of large industrial consumers. In addition, we have updated our analysis on supply side flexibility to include further examination of falling “capture rates” for solar and wind generation and the spectacular growth of battery storage systems amid declining costs in various markets.

This is intended to inform policy and decision making on grid infrastructure and flexibility solutions. Considering the variability in demand and VRE generation the sensitivity of existing flexibility resources such as batteries, interconnectors, long-duration energy storage and demand-side management are also evaluated. Though systems inherently possess flexibility – and new flexibility sources have evolved over time – there is need to keep pace with the growing demand for energy and greater inclusion of variable renewables. Flexibility and grids are essential to ensure that demand for power is balanced with supply, and that sustainable and affordable energy can be provided to all. Download our eBook to find out how to unlock the revenue potential in your energy infrastructure – and where you may already have that flexibility in your organization.
Variable renewable energy share in total generation, by region, 2019-2024
- Global battery storage additions in the power sector surged in 2024, with around 63 GW of new utility-scale capacity installed.
- On the electric grid, electric supply and demand must always be matched – a highly complex exercise for grid operators.
- At times like these, there are a variety of ways that grid operators encourage customers to shift the time they use energy.
- Average capacity of utility-scale battery storage has been increasing in many markets, in line with the evolving market needs for flexibility and capacity as VRE penetration increases.
Operating the grid reliably and responsibly will require incorporating technologies that complement each other – because in many cases, these DERs provide grid reliability measures while supporting the expansion of clean energy. Organizations that leverage their energy flexibility can earn new revenue and/or reduce energy bills, whether by avoiding energy usage during high-priced hours or capitalizing on grid programs and incentives. Greater supply‑side flexibility, more flexible loads, as well as increased storage for energy shifting and for ancillary services can help manage low grid load events. Some capacity may be assigned to provide ancillary services, in a way which precludes them from providing energy during a peak demand event. Industries across many regions currently participate in explicit DR where large consumers commit to reduce consumption during periods of system stress, typically in exchange for financial incentives such as capacity payments or activation payments when load is curtailed.
Accessible flexibility mechanisms for small-scale assets
In the United States, average capacity more than doubled from about 15 MW in 2021 to around 35 MW in 2024. In some countries, such as Germany, home storage capacity is far larger than grid-scale storage. Additionally, batteries may not be fully charged when peak demand events start, and may have a duration which is less than the duration of the demand spike. This can be because of temperature derating, noting that peak demand events are correlated with extreme temperatures. The actual battery discharge during a peak load event may be significantly below aggregate nameplate capacity.
- For end-users, DR flexibility contracts provide inducements in the form of direct payments, rebates, or bill credits for curbing consumption during high-priced, peak-demand periods.
- The utilities pay customers who are willing to reduce or modify their usage for a short period of time to maintain balance while reducing costs.
- Learn how to engage employees in sustainability by building a culture of ownership, behaviour change and everyday action.
- This is becoming more apparent around the world – when the United Nations’ Intergovernmental Panel on Climate Change released their Synthesis Report for their Sixth Assessment Report in 2023, there was notable emphasis on the importance of demand-side measures to prevent catastrophic levels of climate change.
In some cases, such conditions may lead to reverse power flows from distribution grids to transmission grids, congestion and local overvoltage issues, requiring adequate planning and corresponding operational measures. Great Britain has introduced a long-duration energy storage cap and floor scheme requiring projects to discharge at full power for at least eight hours, with an indicative capacity range of 2.7 to 7.7 GWh by 2035. In Australia’s National Electricity Market, 95% of capacity post-2024 is designed for 2 hours or more, and is expected to increase average duration from 1.5 hours in 2024 to 2.5 hours in 2027. China added about 42 GW (101 GWh) of new-type energy storage capacity1 in 2024, corresponding to an average duration of around 2.3 hours. Global battery storage additions in the power sector surged in 2024, with around 63 GW of new utility-scale capacity installed.
Eventually, these resources https://dallasrentapart.com/a-new-unmanned-aerial-vehicle-was-created.html will include fast-responding natural gas “peaker” plants, power plants that run at times of high electricity demand (i.e., when demand is “peaking”). This challenge will only be exacerbated in the future, as intermittent solar and wind are expected to make up 53% of new capacity additions in 2023, the continuation of a years-long trend. In fact, “duck curve” may no longer be the right name – the net load drop is now so steep, some have taken to calling it a “canyon curve.” At this point, the net load for the California Independent System Operator (CAISO) can reach zero or even sometimes go negative in the middle of the day. DERs can also be a part of the solution, helping the grid remain in balance while supporting the expansion of robust technologies that will help decarbonize the nation’s energy landscape. The grid was designed for fossil fuels, not this diverse portfolio of energy sources, so the growth of DERs requires a shift in some approaches for grid operators. Balance has traditionally been achieved through adjusting power generation on the supply side – that is, by turning industrial-scale power plants up or down.
Grid operators are providing more financial incentives to encourage energy users to provide the flexibility needed to help them tackle these new challenges. New-type energy storage excludes pumped hydropower and includes both front-of-the-meter and user-side installations. More widescale capability to control distributed PV and the ability to curtail them in the case of contingencies is another important lever. This is because electricity supply and demand needs to be continuously balanced for system stability. In Italy, the first MACSE auction has already contracted 10 GWh of utility-scale battery storage for delivery in 2028, including about 1.3 GWh from battery storage with durations of 8 hours or more.
Empowering consumers and businesses
Overall, DR-enabling measures can raise the share of industrial load that can be adjusted with limited impact on production, yet they are not fully deployed today, leaving a high share of flexibility unused. Much greater potential exists for industrial DR. Many industrial processes, especially those that rely on heat or operate in batches, can shift their electricity use more routinely via automation or thermal storage. Technically enabled potential includes all loads that already possess the monitoring and control capabilities needed for participation, though this remains significantly below the theoretical potential. Unlocking more of this economic potential becomes possible when adoption constraints and market barriers are reduced or removed. In this evolving energy landscape, demand response (DR) programmes are becoming an increasingly important flexibility tool, enabling households and businesses to shift or shed their electricity use in response to grid or market signals.
Different options are addressed, from increasing control of output from small solar installations, to higher battery deployment, to refining price signals, including offering free electricity to customers. The urgency of climate action demands forward-thinking solutions, and energy flexibility stands at the heart of this transformation. Without energy flexibility, the full potential of renewable energy cannot be realised. A flexible system ensures that electric vehicles, smart appliances, and industrial processes can operate efficiently without overwhelming the grid. Energy flexibility helps stabilise the grid by shifting or reducing demand when needed, ensuring a reliable power supply even during peak periods or extreme weather events. Demand response programs allow consumers to adjust their consumption in real time to benefit from cheaper, cleaner energy.
