Trend analysis: Energy efficiency & demand response — where the value pools are (and who captures them)

Signals to watch, value pools, and how the landscape may shift over the next 12–24 months. Focus on KPIs that matter, benchmark ranges, and what 'good' looks like in practice.

The global demand response management system market reached $94.1 billion in 2024 and is projected to grow at a 31.2% CAGR to exceed $1 trillion by 2033, driven by grid modernization mandates, renewable energy integration requirements, and the electrification of transportation and buildings (Straits Research, 2025). For product and design teams developing energy management solutions, this explosive growth creates substantial opportunities—but only for those who understand the specific value pools, benchmark KPIs, and implementation realities that separate successful deployments from stranded technology investments.

Why It Matters

Energy efficiency and demand response represent the lowest-cost resources in the clean energy transition. Reducing peak demand by one megawatt through demand response costs $50-100/kW-year, compared to $150-300/kW-year for building new peaking capacity. This fundamental economics has driven utility investment exceeding $4 billion in smart grid infrastructure and federal mandates under EPAct 2005 and subsequent FERC orders requiring demand response integration into wholesale markets.

For emerging markets specifically, the opportunity is even more pronounced. Rapid load growth from economic development, electrification initiatives, and rising air conditioning demand is outpacing generation capacity additions. Demand response enables grid operators to balance supply and demand without costly and polluting peaker plant construction. Countries including India, Brazil, and Indonesia are implementing demand response programs modeled on proven approaches from developed markets.

The technology landscape has matured significantly. Automated demand response systems now comprise 68% of the total market, with manual programs declining. Commercial buildings represent 44.6% of deployments, but residential demand response is the fastest-growing segment as smart thermostats, electric vehicle chargers, and home battery systems create aggregatable flexible loads. For product teams, understanding which use cases deliver value—and which remain pilot-stage—is essential for roadmap prioritization.

Key Concepts

Demand Response Program Types

Demand response programs fall into several categories with distinct value propositions. Capacity programs pay for load reduction availability during peak periods, typically compensating customers monthly regardless of actual dispatch. Energy programs pay only when curtailment occurs, offering higher per-event payments but less predictable revenue. Ancillary services programs provide fast-response grid balancing, requiring automated response in seconds rather than hours. Each program type has different technical requirements and value capture potential.

Virtual Power Plants (VPPs)

VPPs aggregate distributed energy resources—batteries, EVs, smart thermostats, and flexible loads—into dispatchable capacity that can provide grid services. The February 2025 launch of Bandera Electric Cooperative's Tesla VPP program in Texas exemplifies this trend, enabling residential customers to earn revenue by allowing their Powerwalls to respond to grid conditions. VPP architectures require sophisticated orchestration software to manage thousands of individual assets in real-time.

OpenADR Protocol

Open Automated Demand Response (OpenADR) provides a standardized communication protocol between utilities and customer systems. The April 2024 launch of 75F's OpenADR-compliant smart building solution demonstrates continued ecosystem development. For product teams, OpenADR compliance is increasingly table-stakes for commercial building energy management systems.

What's Working

Commercial Building Automation Integration

The integration of demand response capabilities into building automation systems has matured significantly. The May 2024 Honeywell-Enel North America partnership enables coordinated load management across HVAC, lighting, and plug loads without dedicated demand response infrastructure. During summer 2024, Enel North America dispatched 411 demand response events totaling 11,000 MWh across 1,700 hours—demonstrating that commercial demand response has achieved operational scale.

Middle East Deployment Success

Abu Dhabi's Department of Energy expanded its demand response project in January 2025, achieving average peak demand reductions of 106 MW with maximum reductions reaching 210 MW. This deployment demonstrates that demand response works in extreme climate conditions where air conditioning loads dominate and grid stress is most acute. For product teams targeting emerging markets, the Abu Dhabi model provides validated reference architecture.

Residential Aggregation Platforms

Companies including OhmConnect, EnergyHub, and AutoGrid have demonstrated that residential loads can be aggregated into utility-scale demand response resources. Smart thermostats, water heaters, pool pumps, and EV chargers provide flexible load that responds to automated signals without meaningful customer inconvenience. The key insight for product teams: customer experience is paramount—successful programs achieve >90% participation rates while maintaining satisfaction scores above 85%.

What's Not Working

Industrial Demand Response Adoption

Despite representing 30%+ of electricity consumption, industrial facilities remain underrepresented in demand response programs. Manufacturing processes with strict quality requirements, safety protocols, and production schedules resist interruption. The highest-value industrial loads (furnaces, compressors, motor drives) often cannot curtail without significant coordination and operational planning that current demand response program structures don't accommodate.

Rural and Underserved Markets

Demand response deployment has concentrated in dense urban markets with advanced metering infrastructure. Rural utilities often lack the communication systems, customer density, and technical expertise to implement effective programs. This leaves significant load flexibility untapped while creating equity concerns about who benefits from grid modernization investments.

Price Signal Complexity

Time-of-use rates, dynamic pricing, and demand charges create theoretical incentives for load flexibility, but most customers don't understand or respond to complex rate structures. Products that require customers to actively manage energy use in response to price signals consistently underperform automated systems that optimize invisibly. For product teams, the lesson is clear: behavioral change approaches have ceiling limitations that technology-enabled automation does not.

FAQ

Q: What demand response program types offer the best revenue opportunity for product developers? A: Revenue opportunity varies by market and customer segment. Capacity programs offer predictable monthly payments ($50-150/kW-year) but require strict performance guarantees. Energy-based programs pay only for actual curtailment events but offer higher per-MWh rates ($100-500/MWh during peak events). Ancillary services provide premium pricing for fast-responding resources but require sophisticated automation and communication capabilities. For most product teams, capacity and energy programs represent the immediate opportunity, with ancillary services as an emerging segment requiring additional technical investment.

Q: How should product teams approach emerging market opportunities differently than developed markets? A: Emerging markets often lack advanced metering infrastructure, reliable communications, and sophisticated utility program structures that developed market products assume. Successful approaches emphasize: cellular connectivity rather than Wi-Fi or Zigbee dependence, offline operation during communication outages, simple user interfaces that work across literacy levels, and partnership with local utilities and regulators to shape program structures. The Abu Dhabi deployment demonstrates that emerging markets can achieve world-class results with purpose-designed implementations.

Q: What technical capabilities differentiate successful demand response products? A: Key differentiators include: sub-second response times for ancillary services applications, predictive load modeling that enables pre-positioning before events, graceful degradation during communication outages, integration with multiple utility program platforms simultaneously, and measurement and verification capabilities that provide auditable load reduction documentation. Products that achieve these capabilities can participate in premium-priced programs unavailable to basic load control systems.

Q: How do electrification trends affect demand response opportunity? A: Electric vehicle charging, heat pump heating and cooling, and building electrification are creating massive new flexible loads. EV charging in particular represents controllable load that can shift by hours without meaningful customer impact. Heat pump water heaters can pre-heat or pre-cool in advance of peak periods. For product teams, designing electrification products with built-in flexibility unlocks demand response revenue streams that improve customer economics and enable grid integration. Products without flexibility capabilities may face regulatory barriers or utility opposition as grids constrain.

Q: What role does artificial intelligence play in demand response? A: AI enables three primary capabilities: predictive analytics that anticipate grid events and customer load patterns, optimization algorithms that maximize curtailment while minimizing customer impact, and personalization that tailors response strategies to individual customer preferences and constraints. AutoGrid, EnergyHub, and GridBeyond have demonstrated that AI-powered platforms outperform rule-based systems by 20-40% in effective load reduction while maintaining higher customer satisfaction. For product teams, AI capabilities are transitioning from differentiation to table-stakes.
