DEBATT reply to Mats Nilsson (piece not captured in this vault — raw only covers Thornström’s reply) — advocating a targeted, time-limited energy-tax cut on electricity used in district-heating (fjärrvärme) electric boilers (elpannor), built around a specific flexibility-resource claim: ~1.2 GW of largely unused capacity already sits in existing DH elpannor, distinguished from individual building heat pumps by being substitutable with other DH production sources at high prices — meaning this flexibility doesn’t compete with, or add to, winter peak electricity demand. Note on source status: Second Opinion ceased publishing 1 July 2026; this is the same policy position and figures as the open data gap in Demand Response › Data gaps (Energiföretagen’s March 2025 begäran om ändring), confirmed still live and being publicly argued as of April 2026.

Key claims

The flexibility-resource argument (core, new mechanism detail): fjärrvärmens elpannor represent ~1.2 GW of largely unused capacity. Unlike a building’s own heat pump, a DH elpanna can be swapped out for another DH production source (biofuel, waste heat, etc.) when electricity prices are high — so running it as flexible load doesn’t require accepting higher electricity draw at the system’s tightest moments. This is framed as “precis den typen av användning som efterfrågas i ett elsystem med allt mer variabel elproduktion” (exactly the kind of use an increasingly variable-generation system needs) — and critically, electricity draw during the coldest periods is unaffected, avoiding the exact failure mode that limits individual heat-pump DR (see Demand Response › Heat pump flexibility: temperature dependence — heat pumps are downward-only exactly when grid stress is highest).

Nordic comparison: neighbouring Nordic countries already apply the minimum tax level (minimiskattenivån) to district heating’s electricity use, on the same systemic-benefit logic (raw does not specify this as the EU-wide minimum rate specifically, just “minimiskattenivån”).

Cost estimate: a targeted tax reduction for DH electricity use is estimated at ~500 million SEK/year, versus >25 billion SEK/year for a general energy-tax cut of the kind Nilsson’s original piece is said to propose — framed as the fiscally deliverable version of a directionally-shared goal.

Rebuttals to Nilsson’s original critique (as characterized secondhand in Thornström’s reply — Nilsson’s own piece is not in this vault, so his claims below are Thornström’s paraphrase of them, not independently verified):

• Building-code weighting: disputes that building energy rules favour district heating — argues the rules’ “purchased energy” (köpta energin) basis actually favours individual heat pumps, since free ambient/ground/solar/water heat harvested on-site isn’t counted; Thornström frames the el/fjärrvärme weighting factors as an attempt at technology neutrality that in practice assumes lower-efficiency heat pumps than what’s typically installed today. (No numeric weighting factors are given in this raw text.)
• No lock-in: standard DH customer contracts carry a 3-month notice period — customers can switch heating solutions freely
• Price instability: attributes recent DH price rises primarily to biofuel costs roughly doubling since Russia’s invasion of Ukraine, not business-model protection; states the DH sector absorbed most of this cost as a “krockkudde” (shock absorber), running near-zero aggregate profit in 2023–2024 rather than passing the full increase to customers
• Denmark comparison: notes Denmark’s often-cited DH model is far more regulated than a market comparison implies — extensive energy planning, price regulation, and historically mandatory connection

Mats Nilsson’s original argument: per Thornström’s characterization, Nilsson argues Energiföretagen is protecting a specific district-heating business model, and separately raises the energy tax on electricity and the building-code energy requirements. Nilsson’s own piece, his exact framing, and any figures or case citations he may use are not captured in this vault — Thornström’s reply is the only raw text available for this exchange, so nothing beyond this two-sentence characterization can be verified or reported as Nilsson’s claim.
