What MAVIR data reporting needs to be automated?

MAVIR Zrt. is the Hungarian TSO. Reporting areas: system load (planned and actual, gross and net), settlement metering data, cold reserve, frequency containment, balancing market bids, REMIT inside information. REMIT (Reg. 1227/2011) makes major-event reporting an obligation for any market participant. We build the TSO data link: ICCP / TASE.2 or ENTSO-E public feed, automated settlement reports, REMIT event log.

What is the CBAM definitive period in 2026?

The Carbon Border Adjustment Mechanism (Reg. 2023/956) entered the definitive period on 1 January 2026. Through end-2025 the regime was a transitional quarterly report; from 2026 importers have to declare embedded emissions (steel, aluminium, cement, fertilisers, electricity, hydrogen) and acquire CBAM certificates — first declaration 31 May 2027 for 2026, with the amended deadline now 30 September. For energy importers and heavy-industry customers we build the CBAM reporting pipeline: emissions calculation, embedded electricity carbon intensity, EU CBAM Registry sync.

Do you work with IEC 61850 substation automation?

Yes. IEC 61850 is the de-facto digital substation standard: GOOSE (Generic Object Oriented Substation Event) is Ethernet multicast with sub-4ms message delivery for protection; MMS (Manufacturing Message Specification) is the client-server transactional layer (parameterisation, data acquisition); Sampled Values (SV) is current and voltage sampling from the digital merging unit. MAVIR substations, for instance, are linked over IEC 61850-compatible communication. We build the SCD (Substation Configuration Description) integration and the SCADA bridge: IEC 61850 -> DNP3 / IEC 60870-5-104 -> cloud telemetry.

Smart meter / MDM stack — DLMS/COSEM and AMI?

DLMS/COSEM (IEC 62056) is the smart-meter standard on both Hungarian electricity and gas — the same protocol family as most of Europe. AMI (Advanced Metering Infrastructure): meter -> concentrator -> MDM (Meter Data Management). Typical MDMs: Itron Enterprise Edition, Oracle Utilities Customer Cloud, Honeywell EnergyAxis. We build the meter-to-cash pipeline: DLMS read, validation (VEE), MDM sync, billing handoff, customer portal (monthly / 15-minute consumption). Smart-meter security: GMAC authentication, AES-128, scheduled key rotation.

How much does an energy software project cost?

Typical ranges: SCADA / EMS bridge with IEC 61850 6-10 months, HUF 35-90M. MDM smart-meter pipeline (DLMS/COSEM) 5-9 months, HUF 28-75M. CBAM reporting module (importers) 3-5 months, HUF 12-30M. MAVIR / MEKH data-reporting pipeline 4-7 months, HUF 18-45M. NIS2 essential-entity compliance program (risk analysis + Article 21(2) ten measures) 6-9 months, HUF 30-80M. Continuous retainer HUF 1-3M / month. Exact quote after a 30-minute scoping call.

TL;DR

Energy is an essential entity under NIS2 Annex I — fines >= EUR 10M or 2%, Hungary's Act LXIX of 2024 in force 2026-01-06.
CBAM (Reg. 2023/956) definitive period since 2026-01-01, first annual declaration in H1 2027.
MAVIR data reporting (system load, REMIT inside information) is automatable via the ENTSO-E API + REMIT URM.
DLMS/COSEM (IEC 62056) is the smart-meter standard EU-wide; IEC 61850 handles substation automation.
Project ranges: HUF 12-90M depending on scope, EU-region and on-prem deploy.

Pain map — what energy companies are dealing with right now

Concrete, named problems from Hungarian electricity, gas and district-heating providers.

NIS2 essential entity — no Article 21(2) program yet

Power, gas and district-heating providers are all essential entities (NIS2 Annex I). Many organisations haven't lit up the Act LXIX of 2024 ten-measure implementation and the 24h/72h reporting pipeline, while the fine threshold is at least EUR 10M or 2% of global turnover.

MAVIR data reporting in Excel macros

Many smaller market participants still hand-build TSO load and settlement reports. An hour-late filing can breach REMIT (Reg. 1227/2011) inside-information reporting — an automated pipeline is needed.

Smart meter MDM siloed — VEE done by hand

15-minute data coming from DLMS/COSEM reads ends up in Excel / SAS for VEE at many providers. Moving to a real MDM (Itron / Oracle Utilities / Honeywell) automates conflict resolution and the billing handoff.

CBAM definitive period from 2026 — no data warehouse yet

Importers of steel, aluminium, cement, hydrogen and electricity have to file the first CBAM declaration by 31 May 2027 (or 30 September after the amendment) for 2026. The embedded-emissions calculation pipeline (default values, actual measurement, third-party supplier) is incomplete at many companies.

OT / IT segmentation — IEC 61850 GOOSE on the office LAN

At several Hungarian mid-market players, substation IEC 61850 GOOSE traffic and the office IT LAN share the same 1G uplink. Under NIS2 supply-chain and cryptography requirements that's not sustainable — Purdue-level segmentation is needed.

GYIK

Energy — frequently asked

Yes. NIS2 Annex I lists energy (electricity, district heating and cooling, oil, natural gas, hydrogen) as essential. Hungary's Act LXIX of 2024 (in force 2026-01-06) takes this on in full. The fine threshold is at least EUR 10 million or 2% of global turnover. The Article 21(2) ten measures (risk analysis, incident handling, business continuity, supply-chain security, cryptography, MFA etc.) and Article 23 24h/72h/1-month incident reporting are mandatory. The Commission's reasoned opinion of 7 May 2025 indicates Hungary's full transposition is still ongoing — being proactive on compliance pays off.
