Neutrality component
The neutrality component is the per-MWh adjustment a TSO adds to the imbalance price so it neither profits nor loses from balancing operations. It absorbs residual costs — reserve procurement, EU-platform fees, IT, IGCC settlement — that the basic balancing-energy reference price doesn't cover. Article 44 of EBGL Regulation (EU) 2017/2195 makes this financial neutrality legally mandatory for every European TSO. Each Baltic TSO calculates its own component to a methodology approved by the national regulator.
The neutrality component (sometimes called the neutralisation charge) is the per-MWh adjustment a TSO adds to the imbalance price so the TSO neither profits nor loses from running the balancing function. It absorbs the residual costs that the balancing-energy reference price does not already cover. Financial neutrality of TSO settlement is mandated by Article 44 of the Electricity Balancing Guideline (Reg (EU) 2017/2195).
What costs it covers
The reference price reflects the cost of the activated MWh itself — the bid that cleared in MARI or PICASSO. Everything else the TSO spends running the balancing function lands in the neutrality component: capacity procurement on the Baltic Balancing Capacity Market, European platform membership fees, IT and operations costs, the IGCC settlement balance for avoided activations, dispute resolutions and any residual mismatch between what the TSO charges BRPs and what it pays BSPs.
How it enters the imbalance price
For each Market Time Unit (MTU), the imbalance price equals the balancing-energy reference price plus or minus the neutrality component. The sign depends on the Direction of System Balancing (DSB): short BRPs in an up-regulated MTU pay reference + neutrality, while long BRPs in a down-regulated MTU receive reference − neutrality. That asymmetry is what makes the TSO whole at the end of each settlement period — the component is sized so the integral of all imbalance settlements over a billing period nets to the TSO's actual residual balancing cost.
Estonia and the Baltic methodology
Each Baltic TSO publishes its own neutrality methodology, approved by the national regulator — in Estonia by Konkurentsiamet, in Latvia by SPRK, in Lithuania by VERT. The Estonian methodology — Bilansiteenuse hinna arvutamise ühtne metoodika, approved by Konkurentsiamet decision 7-10/2025-001 on 10 January 2025 — calculates the monthly tariff by dividing the residual balancing costs by the BRPs' aggregate imbalance volume across the previous 12 calendar months, then publishing the resulting €/MWh adder at least two months before it applies. Per the same methodology, any over- or under-recovery from the previous reporting period is corrected in the next calendar month so the TSO's settlement nets to zero on a rolling basis. Because the Baltic TSOs operate as a joint LFC block since the 9 February 2025 Continental synchronisation, the three methodologies are increasingly aligned even though each TSO settles its own area separately.
Where you see this in Baltic data
The Baltic Transparency Dashboard publishes the applicable neutrality component per MTU for each of the three Baltic countries (current and legacy series), alongside the imbalance price and DSB. For BRPs and battery operators, the neutrality component is what makes the realised imbalance price differ from a back-of-envelope estimate based purely on MARI clearing prices: see the live Estonian imbalance price.

Frequently asked
- What is the neutrality component in electricity balancing?
- It is a per-MWh charge or credit the TSO adds to the imbalance price so the TSO's settlement of balancing operations nets to zero over the billing period. It exists because the reference price covers only the activated MWh itself, not the TSO's residual costs of reserve procurement, IT, platform fees and avoided activations.
- How is the neutrality component calculated?
- Each TSO sums its residual balancing costs not recovered through the reference price — capacity-market spend on BBCM, MARI/PICASSO/IGCC fees, IT and operations, dispute resolutions — and divides by the BRPs' aggregate imbalance volume across a defined window of historical actuals (the previous 12 calendar months under Estonia's official methodology, Konkurentsiamet decision 7-10/2025-001). Any over- or under-recovery from the previous period is corrected in the next calendar month so the TSO settles to zero on a rolling basis.
- Why must the TSO be financially neutral?
- Article 44 of the EU Electricity Balancing Guideline (Regulation 2017/2195) requires that TSOs neither profit nor make a structural loss from balancing settlement. Profit would create perverse incentives to over-activate; losses would have to be socialised via grid tariffs. The neutrality component is the mechanical adjustment that enforces this.
- Does the neutrality component change every interval?
- No. Most TSOs publish a fixed value for a defined window — typically monthly in the Baltics — and apply it uniformly to every Market Time Unit in that window. The recalculation reflects updated cost forecasts and any over- or under-recovery from the previous period.
- Where can I see the current Estonian neutrality component?
- Elering publishes the applied value in its balancing-service terms and conditions on elering.ee/en/balancing-service. The Baltic Transparency Dashboard publishes the per-MTU realised neutrality component in its dedicated Neutrality Component report.
