3.9 Description of any unique features, technology, strategy, etc., that sets your company apart from other
suppliers.

Kaplan Experience and Expertise.
Mavel is the global leader in the design and production of low head Kaplan turbines under 10 MW. The company’s

expertise began with its location in the heart of Central Europe in the region where Viktor Kaplan invented the low
head Kaplan turbine over 100 years ago. Leadership in small Kaplan installations evolved over the past 25 years through
significant experience. Since its founding, Mavel has provided engineering and equipment solutions for over 300 Kaplan
turbines for over 200 projects on every continent of the globe.

Guaranteed Results.
Mavel has provided performance and delivery guarantees for every project it has undertaken since 1990. To date,
Mavel has not been assessed liquidated damages on any project for not meeting these guarantees.

European Quality.

Mavel’s headquarters and primary manufacturing facility is just outside of Prague, Czech Republic in the heart of
Europe, Mavel provides 100% European engineering, production and sourcing on its delivery. For the Jackson Mills
HPP, Mavel is recommending working with a team of Czech Republic companies to provide the full mechanical scope.
Mavel has significant experience working with each vendor proposed.

Local Presence.
The main office for Mavel’s operations in the Americas is based in Boston. This location provides easy access for any
interface needed between the Owner, EPSI, Engineer and Mavel.

Global Service.

With an extensive global installed base of Mavel turbines, the company’s service department is equipped to work on
projects around the world. For the Jackson Mills HPP, the US based Project Manager would oversee any maintenance
or service work with support, as needed, from the Czech Republic team.

Product Quality and Quality Control. Mavel has 1SO-9000:2008, ISO-3834-2:2005, ISO-14001:2004 and OHSAS
18001:2007 certifications and follows strict quality control protocols in manufacturing and purchasing. All of Mavel’s
sub-suppliers are also ISO certified and are committed to quality.

Research & Development.

Imagination, innovation and optimization are at the core of Mavel’s research and development efforts. Working on
challenges defined by sales engineers, the R&D Team develops solutions with the support of the over 1,000 years
combined experience of the company’s 60 civil, hydraulic, mechanical and electrical engineers. The engineering team
is supported with state-of-the-art 3-D modeling software and through partnerships with educational institutions and
technical laboratories.

Mavel has over 100 proprietary turbine designs. Each year, the R&D Team, working with design engineers, develops
new turbine designs to meet higher efficiencies, minimize civil costs, utilize new materials, simplify installation
procedures and time and/or adapt proven turbine technology to customer specific needs.

Design innovations have included the development of modular micro turbines, Kaplan turbines with an operating range
as low as 1.5 meters and high efficiency Francis and Pelton runners suitable for heads up to 1000 meters.

The R&D Team uses both standard and proprietary computational fluid dynamics software. This software models
dynamic hydraulic flows and allows for the effective development and testing of new hydraulic profiles and turbines.
This shortens the development process. The illustrations on the right depict examples of streamlined visualizations of
the velocity fields inside Kaplan, Francis, Pelton and micro turbines.

Mavel’s R&D Team stays abreast of developments in both material and manufacturing technology. Minimizing
production costs and maximizing quality and product life are key considerations in exploring material innovation.
Manufacturing process and control are fundamental. The latest innovation in this area for Mavel was the installation
of a state-of-the-art CNC 6-axis prototype machining center that allows for the highest accuracy transfer from design
to production.

Cavitation

The Vendor shall warrant that all turbine components be free of excessive cavitation damage during
the first 10,000 hours of operation, provided that:

(A) The minimum tailwater elevation does not fall below the 95.686 feet NAVD 88 value present in

(B) The maximum guaranteed turbine output of 1127 KW (at_19.9 feet net head) is not exceeded for more than 100
hours of operation, and the turbine is not operated below the minimum guaranteed output of 338 KW for more
than 500 hours.

Excessive cavitation shall be defined as the removal of metal at a rate exceeding 6.61 LBS during the first 10,000
hours of operation.

(The daily power plant log shall serve as the basis for determining unit loads and operational times.)
