Swedish Household Demand Response — Consumer Adoption and Barriers

Empirical evidence from Swedish household surveys (2022–2024) on attitudes to Demand Response, aggregator delegation, and market participation. The central finding across all sources is a structural conversion gap: households are informally flexible but rarely formally enrolled in any market-based service. The primary barrier is not knowledge or attitude but opportunity — fragmented tariff designs, absent standardised interfaces, and underdeveloped aggregation services.

Acceptance and aggregator delegation

Uppsala University’s USER research group (FlexAbility 2025) conducted the most comprehensive Swedish survey to date on household attitudes to flexible electricity use and aggregator delegation. 2,872 responses across four DSO/aggregator customer groups; results must be interpreted cautiously as the sample overrepresents men, highly educated, high-income, and villa-owning households.

Current control of flexible assets — among households that own each asset:

Home batteries are already deeply embedded in aggregator ecosystems — 65% of battery owners delegate control to an aggregator. This likely reflects that the primary reason to buy a home battery is to generate aggregator revenue (e.g., FCR market participation via CheckWatt). By contrast, heating control remains predominantly manual or owner-automated; only 3% delegate.

What drives and blocks aggregator delegation (linear regression, 1–7 scale):

The knowledge deficit finding: lack of knowledge about aggregation options has no statistically significant effect on propensity to delegate. This challenges the common policy assumption that awareness campaigns are the primary lever for unlocking household participation. Economic incentives dominate: earn money → cut costs → maintain control → trust.

Potential customers are cautious about delegating (2.96/7 — barely above neutral). Active customers who already participate are enthusiastic (4.93/7). The gap reflects a genuine behavioral threshold that product availability alone does not overcome.

Factors with significant positive effect on signing an aggregator contract: higher education, villa ownership, higher income. Apartment dwellers are significantly less likely — because they have fewer individually controllable assets. Reaching apartment dwellers requires collective solutions through housing associations (bostadsrättsföreningar), not individual contracts.

Adoption and the conversion gap

An Ei-commissioned survey by IVL (January 2023, n=10,328 households) provides the broadest empirical baseline for Swedish household adoption at the time of peak post-2022 awareness. (Source - IVL Konsumentperspektiv Efterfrågeflexibilitet (2023))

Penetration: 34.2% of Swedish households actively steer electricity use. Of those who steer: 75.6% use manual behavioral change; 28.3% use timers; 23.6% have smart control. Only 1 in 5 of those who steer has automatic control — manual behavior dominates. Across all households, only 8% have any smart control.

The 2022 activation event: 75.6% of households that had started managing electricity did so in 2022, most in autumn 2022. December 2022 prices were the highest ever recorded for that month. The survey was fielded in January 2023, at peak awareness — making these figures a probable upper bound rather than steady-state.

Why households become flexible: ranked motivations: (1) reduce electricity trading costs via hourly pricing; (2) reduce grid costs; (3) contribute to grid relief; (4) environmental benefit; (5) tech interest. Economic incentives dominate; social motivations are real but secondary. Before 2022, early adopters were tech enthusiasts — from 2022, economics became the primary driver.

Why households don’t become flexible: (1) don’t believe savings would be large enough; (2) complexity of hourly pricing and technical solutions; (3) comfort/convenience conflicts; (4) locked into fixed contracts. A contract confusion problem: ~9% of non-hourly-pricing households believe they already have hourly pricing, confusing monthly-average rörligt pris with timpris.

Uncertainty effect on adoption: uncertain (vs guaranteed) savings eliminated 24 percentage points of potential heating-control adopters (63.8% → 40.1%) — but had almost no effect on EV owners (91.0% → 89.4%, who are more experienced with electricity costs) and a moderate effect on behavioral change (67.1% → 57.8%). Predictable, guaranteed savings are critical for unlocking smart-control adoption. Notably, “prioritize renewable energy” and “reduce grid load” had no significant effect on smart-control adoption decisions — but did influence behavioral-change decisions, where the action feels more directly connected to making a real difference.

A Ramboll follow-up survey (January 2024; n=1,173 villa households + n=175 market actors) quantifies the central conversion problem (Source - Ramboll Nyckeltal Hushålls Efterfrågeflexibilitet (2024)):

The 42% → 2.8% gap is the central conversion problem: most flexible households are willing to act but have no accessible path to formal participation. Ramboll’s COM-B behavioral diagnosis identifies the Opportunity barrier as the most binding: only 21% of DSOs offer time-differentiated tariffs; there is no standardized service interface; BSP/BRP market structure is complex. This points to structural solutions — tariff reform, data standardisation, standard contracts — rather than consumer education campaigns. Zone variation: SE4 timprisavtal uptake (18%) is 4.5× higher than SE1 (4%), driven by SE4’s more extreme price history reducing the opportunity barrier.

Consumer service landscape

A parallel market scan (AFRY, November 2023) maps the supply-side landscape of digital services available to Swedish electricity consumers. (Source - AFRY Styr och Informationstjänster Konsumenter (2023))

The scan identified 44 services from 172 actors, divided into:

• 36 information services — showing data, prices, costs; no device control
• 8 control services — actively controlling consumption or generation on behalf of the consumer

The 8 control service types: price optimisation, peak power (effekttariff) optimisation, market-based load balancing, local DSO flexibility, EV smart charging, energy sharing, grid monitoring, and battery aggregation.

Three consumer segments reflecting different readiness levels:

“Optimeraren” is the segment most underserved by current market offerings despite being the highest-value flexibility resource.

The effekttariff integration gap: control services for peak power optimisation exist but are underdeveloped. The structural reason: each DSO designs its effekttariff differently, making standardised control integration costly. This has been confirmed as an Ei-level concern: fragmented DSO effektavgift models are an obstacle to developing automatic steering services. Elmarknadshubb‘s DHV will address this directly — machine-readable network tariffs for steering services are explicitly included as a DHV data category, allowing automated peak-control services to read each DSO’s tariff via a standardised API.

2024 snapshot — penetration, pricing, EVs

Ei‘s Flexläget 2026 (PM2026:02, December 2024 surveys; n=1,020 households, n=33 suppliers, n=49 DSOs) is the first edition of a planned annual statistics series tracking the state of demand flexibility in Sweden. (Source - Ei Flexläget 2026 (PM2026-02))

Effective price signal reach: the headline timprisavtal penetration rate (15–22% depending on housing type) overstates how many households actually face hourly price signals. 24% of households lack their own grid connection (mostly apartments sharing through a BRF) — without which hourly pricing passes no signal. Result: only ~12–13% of all Swedish households actually face hourly spot prices hour by hour.

Why households don’t switch to timprisavtal: (1) “I believe timprisavtal risks being more expensive” — 28%; (2) “Hard to predict costs” — 25%; (3) “Haven’t had time to switch” — 25%; (4) “Wasn’t aware it exists” — 8%. Ei has since required suppliers to proactively inform customers about contract differences (EIFS 2024:2) and replaced the term “rörligt pris” with “månadspris” to clarify the distinction.

EV and smart charging (2024 data):

• 14% of households have a plug-in vehicle — Småhus 26%, Flerbostadshus 6%
• 29% of those with an EV and home charging use smart charging — 26% lack the function; 21% have it but don’t use it; 23% don’t know
• Shared parking barrier: 81% of apartments have charging on shared/common parking — smart charging services for this group are very underdeveloped
• Heat pump automatic steering: only 3% of heat pump owners; home battery automatic steering: only 25%

Tariff knowledge gap: only 20% of households know that effektavgift is part of their network tariff (47% say “don’t know”) — the factual knowledge gap underlying resistance to demand charge reform.

Market penetration: only 1 in 10 DSOs operates or participates in a local flexibility market; only 1 in 10 suppliers coordinates its steering with any other market actor. See Flexibility Market › Actor composition for implications on coordination failure.

Cross-cutting findings

Across all four sources, the consistent pattern is:

1. Economic incentives dominate: whether it is delegation willingness, adoption motivation, or contract switching, money beats environmental and social motivations at every stage.
2. Knowledge is not the binding constraint: the FlexAbility finding (knowledge deficit not statistically significant) aligns with Ramboll’s COM-B diagnosis — the barrier is structural Opportunity, not awareness.
3. Structural solutions are required: tariff harmonisation (Villkorade Avtal, effekttariff standardisation via Elmarknadshubb/DHV), standardised service interfaces (Network Code on Demand Response), and BSP market development — not consumer campaigns.
4. The apartment gap is systemic: apartment dwellers have lower DER ownership, shared parking, no individual grid connection, and 5% timprisavtal penetration vs 22% for villa owners. Collective solutions through BRFs are required, not scaled-up individual approaches.
