The 2025 IGSHPA Annual Conference was in partnership with the Geothermal Alliance of Illinois (GAOI) in Champaign, Illinois.
IGSHPA has participated in NGWA’s Ground Water Week Expo for the past three conferences with great success. We will continue to support NGWA conferences. IGSHPA decided to venture out a bit for the 2025 conference and chose a Midwest location at a smaller venue with a dedicated conference center. We were excited to partner with GAOI in our efforts to involve state and provincial associations. IGSHPA’s 4th annual conference of the new independent IGSHPA organization included 8 tracks and more than 50 speakers.*
