GEKAL-KVA Buchs

What GEKAL-KVA Buchs does

GEKAL-KVA Buchs is a public-sector municipal association (Gemeindeverband für Kehrichtbeseitigung Region Aarau-Lenzburg) founded in 1969 that operates the KVA Buchs waste-to-energy facility in Buchs, Aargau, Switzerland. The facility processes approximately 140,000-145,000 tonnes of municipal and industrial solid waste annually across two parallel incineration lines operating at 800-1000°C with comprehensive flue gas treatment (electrostatic precipitator, two-stage wet scrubber, DeNOx SCR system). It serves over 100 member municipalities in Aargau representing more than 350,000 residents, plus industrial customers and cross-border waste from Landkreis Waldshut (Germany).

The business operates on an integrated waste-to-energy model. Combustion heat generates steam in two 36 MW thermal boilers (40 bar, 400°C), which drives an 11 MW turbogenerator for electricity production (66,000-70,000 MWh annually, sold to CKW, Alpiq and other utilities) and feeds district heating through FEWAG (60% GEKAL-owned) to industrial and commercial customers including Mittelland Molkerei, Delica AG, Mibelle AG, Eniwa AG, and Migros operations. A pilot hydrogen electrolyzer commissioned end of 2023 participates in the Swissgrid secondary control reserve market. Revenue is generated from three transaction-fee streams: waste incineration fees (CHF 75/t for municipalities, CHF 150/t for industry), electricity sales, and district heating sales, totaling approximately CHF 25M annually.

The asset base is capital-intensive with total equity of CHF 179.9 million, 94.6-95.6% operational availability, and a pre-financing reserve of CHF 100 million supporting the KVA 2035+ strategic replacement program (estimated CHF 200-300M). The Energy Cockpit management software optimizes production scheduling across steam, electricity, district heating, and hydrogen. The facility is self-sufficient in electricity and replaces approximately 14.4 million liters of heating oil annually. Leadership is undergoing planned succession for the Geschäftsleiter and Betriebsleiter positions, with revised governance regulations taking effect 1 January 2026.

Revenue model

1. Waste Incineration Fees (Verbrennungsgebühren): Primary revenue stream from charging member municipalities, industrial customers, and private waste producers for thermal waste treatment. Pricing is tiered: CHF 75/t for municipalities, CHF 150/t for industry, with volume-based minimum fees.
2. Electricity Sales: Sale of generated electricity to public grid. Approximately 66,000-70,000 MWh annually sold to CKW, Alpiq, and other utilities. Revenue highly dependent on market prices (CHF 110-120/MWh range).
3. District Heating Sales: Sale of steam and hot water to Fernwärme Wynenfeld AG (FEWAG) for regional district heating network. Approximately 122,000-144,000 MWh annually sold at CHF 25-27/MWh.
4. Hydrogen Production: Emerging revenue stream from hydrogen production via electrolysis for participation in Swissgrid secondary control reserve market, contributing to grid stability.

Core offering

GEKAL-KVA Buchs operates a municipal waste-to-energy incineration facility in Buchs, Aargau, processing approximately 140,000 tonnes per year of municipal and industrial solid waste across two combustion lines. The thermal treatment generates steam that drives turbines to produce electricity and feeds a regional district heating network, delivering energy recovery services to 100+ member municipalities, industrial customers, and private waste producers.

Product overview

KVA Buchs operates as a waste-to-energy facility (Kehrichtverbrennungsanlage) managed by GEKAL (Gemeindeverband für Kehrichtbeseitigung Region Aarau-Lenzburg). The facility provides integrated waste management services through two incineration lines with a combined capacity of 140,000 tonnes annually. The core offering consists of thermal waste incineration converting municipal and industrial waste into valuable energy, producing electricity via steam turbine (Stromproduktion) and district heating through the Fernwärme network (Fernwärme). Supporting infrastructure includes the Heisswasserzentrale for hot water production, the Energy Cockpit for energy optimization management, and a pilot hydrogen plant for grid stabilization. The facility also processes slag and combustion residues for material recovery and recycling.
