Hydropower Engineering

What Hydropower Engineering does

Hydropower Engineering Ltd is a New Zealand-based specialist hydropower consulting firm founded in 1999 in Hamilton by Giuseppe (Jo) Grilli, who previously led hydropower engineering at the New Zealand Electricity Department. The firm provides mechanical and electrical engineering and project management services covering the 'water to wire' spectrum of hydropower generation — including plant performance investigations, technical specifications, hydraulic gate detailed design, turbine hydraulic model test witnessing, hydro development studies, site supervision, comprehensive dam safety reviews, and participation on Independent Panels of Experts. The company also operates two proprietary training products: the Turbine Governor Course (running since 1984) and the Hydropower Technology Course (established 1993, delivered 65+ times).

The business is led by three directors — Grilli, Joachim (Joe) Pott (joined 2008), and Chris Lucas (joined 2022) — supported by specialist contractors, with offices in Hamilton, Wellington, and Auckland. Revenue is generated through project-based professional services engagements plus structured training courses. The client base consists of major hydropower generating utilities and dam owners in New Zealand (Genesis Energy, Meridian Energy, Mighty River Power, Contact Energy, Mercury, Transpower), Australia (Snowy Hydro, Hydro Tasmania, Mechanical Technology), Canada (BC Hydro), and an expanding roster in Chile, China, Tajikistan, Malaysia, Indonesia, the Philippines, Fiji, and the UK.

Distribution is almost entirely relationship-driven: the company acquires work through its reputation as a 'consultant of choice', word-of-mouth referrals, and multi-decade relationships with senior utility engineering staff. The firm holds a long-standing partnership with Damwatch Services Ltd for joint delivery of comprehensive dam safety reviews, and supports international engineering firms (e.g., AECOM) on technical due diligence for hydropower asset transactions. There is no public disclosure of revenue, funding, or headcount figures beyond the 11-50 band.

Direct peers

• Entura: Australia-based hydropower and water consulting firm (owned by Hydro Tasmania) providing M&E advisory, dam safety, and asset management services to utilities across the Asia-Pacific — directly comparable in service mix, client base (Hydro Tasmania is also an HE customer), and scale.
• Norconsult: Nordic-headquartered multidisciplinary engineering firm with a dedicated hydropower practice covering M&E advisory, dam safety, and owner's engineering. Comparable niche focus on hydropower consulting with international reach.
• Knight Piésold: Global specialist engineering consultancy focused on hydropower, dams, and water resources. Offers M&E advisory, feasibility studies, and dam safety reviews — directly comparable niche expertise and customer overlap (developers, utilities) across multiple continents.
• Damwatch Services: NZ-based specialist dam safety and hydropower consulting firm with complementary civil engineering expertise. Damwatch is both a partner (on 10+ comprehensive dam safety reviews) and a direct peer competing for the same NZ dam safety and hydro asset management mandates.

Broad incumbents

• AECOM: Global infrastructure consulting firm with a sizable water and hydropower practice. AECOM is both a competitor (large hydropower mandates) and a client of HE (engaged HE for due diligence on Zhaoheng and Nam Theun II turbine issues).
• Stantec: Global engineering consultancy with a substantial hydropower and dam safety practice (including legacy MWH Global). Competes for hydropower owner's engineering and dam safety reviews across the same Asia-Pacific and North American markets HE serves.
• AFRY (formerly Pöyry): Large European-headquartered engineering and design firm with a globally recognised hydropower practice. Competes for feasibility, owner's engineering, and dam safety mandates but at significantly greater scale and broader service portfolio than HE.
• SMEC (part of Surbana Jurong): Global engineering consultancy with a substantial hydropower and dams practice (legacy Snowy Mountains Engineering Corporation). Chris Lucas previously worked at SMEC, and HE competes with SMEC for hydropower feasibility, owner's engineering, and IPoE mandates in Asia-Pacific.
• Tractebel: Belgium-based engineering consultancy (Engie group) with a leading hydropower and dams practice. Competes for owner's engineering, feasibility, and IPoE mandates on major international hydro projects — directly comparable technical service offering.

Emerging players

• AF-Consult: Swiss engineering consultancy with growing hydropower and renewable energy advisory practice. Provides owner's engineering and feasibility services to European utilities, with an emerging footprint in Asia and Africa that overlaps with HE's international engagement profile.
