Event overview
RENEXPO INTERHYDRO is the hydropower and renewable-energy meeting point for Austria, Switzerland, southern Germany and the wider Alpine region. The 2027 edition runs 17–18 March at Messezentrum Salzburg, bringing turbine and steel hydraulic engineers, civil works contractors, plant operators, utilities, planners and storage specialists onto one compact show floor.
Alongside the exhibition, the RENEXPO forum covers river management, ecology, grid integration, hydrogen and sector coupling. With about 90 exhibitors and 1,327 visitors at the last edition, the event is small enough for focused meetings yet broad enough to cover the full water-to-power value chain.
It suits buyers who want technical depth and direct access to project engineers in a two-day window.
TL;DR
Visit to compare turbine, steel hydraulic and civil-works suppliers in one place, to hear how operators are planning refurbishment and flexibility projects, and to meet the engineers and authorities who shape Alpine hydropower schemes. The compact floor makes it realistic to hold several technical meetings in a single day.
Exhibit to reach decision-makers from utilities, plant operators, engineering consultancies and public authorities across the Alpine region. The show’s tight focus on hydropower and renewable integration means stand conversations start with project specifications rather than general marketing, and the two-day format keeps travel and stand costs contained.

Edition recap
RENEXPO 2026 brought 1,327 visitors and 90 exhibitors to Messezentrum Salzburg, with 20 guests joining the political and business talks.
Impact
The show is small by European trade-fair standards, but its 1,327 visitors and 90 exhibitors are concentrated in hydropower, civil engineering and renewable integration. For a supplier, that means fewer casual visitors and more conversations with people who specify, permit or operate Alpine assets. The two-day format rewards a prepared meeting schedule rather than a large stand.
Audience quality
The audience is technical and regional: utility and plant operators, turbine and steel hydraulic engineers, civil and environmental consultants, authorities and project developers from Austria, Switzerland, southern Germany and neighbouring Alpine markets. Buyers arrive with live refurbishment, compliance and grid-connection questions, so specification sheets and reference projects matter more than broad brand campaigns.
Exhibitor outcomes
ROI depends on fit. A turbine, penstock, control-system, fish-bypass or storage supplier with Alpine references can use two days to meet a high share of the region’s active buyers at modest travel and stand cost. A mass-market solar or consumer-energy brand will find the audience too narrow. Set a target of qualified meetings rather than raw footfall, and follow up within 48 hours while project details are fresh.
Intelligence
Key market insights, trends, news and related events to help you understand the bigger picture.
Why it matters
Austria’s electricity mix is anchored by Alpine hydropower, and the country’s energy transition depends on making that fleet more flexible while connecting more wind, solar and storage. Salzburg sits at the centre of the Austrian, Bavarian and Swiss hydro corridor, so a focused show here gives suppliers access to operators and engineers who are actively refurbishing, digitising and expanding plant.
Key trends shaping this market and its wider industry.
Flexibility and pumped storage
Operators are adding or upgrading pumped-storage and flexible generation capacity to balance variable wind and solar output.
What it changes: Flexibility upgrades create demand for turbines, control systems, grid services and refurbishment expertise.
Refurbishment and digitalisation of existing plants
Many Alpine hydro plants are decades old, so condition monitoring, digital control and efficiency upgrades compete with new-build projects for capital.
What it changes: Refit work is a steady, specification-led route for suppliers who can demonstrate reliability in operating plants.
Sector coupling and hydrogen
Surplus hydro and renewable power is increasingly linked to heat, industry and hydrogen production rather than sold only as electricity.
What it changes: Sector-coupling projects bring new buyers from storage, Power-to-X and industrial decarbonisation into the hydropower supply chain.
RENEXPO INTERHYDRO sits early in the spring trade-fair season, between the winter energy-policy shows and the summer solar and wind events. Buyers planning a European energy calendar can pair it with the adjacent shows below.

Plan your trip
Best day to visit: 17 March 2027 (Day 1)
Day 1 has the longer opening hours (09:00–17:00) and the best chance to catch exhibitors before schedules fill. Arrive at opening, take the first supplier meetings before the aisles get busy, and leave the afternoon for the forum and follow-ups.
Book travel and a refundable hotel — Fly into SZG or MUC; stay in Elisabeth-Vorstadt or Schallmoos.
Register and print or download the ticket — Use the Messezentrum webshop; keep the ticket for re-entry.
Build a shortlist of exhibitors and forum sessions — Pick 8–10 stands and two programme blocks; leave room for follow-ups.
Confirm meetings and travel times — Allow 20 minutes between halls and a buffer for registration.
Pack badge, layers and business cards — March weather is changeable; bring a waterproof jacket and comfortable shoes.
Arrive, collect badge and walk the hydropower hall before crowds
