1. INTRODUCTION

Eaton Corporation has a successful record of deploying turnkey hydro electro-mechanical
modernization projects spanning more than 50 years in government, utility and privately-owned
hydro-electrical facilities. We are well positioned with an experienced and committed team to
lead the Jackson Mills electrical modernization with a modern and cost-effective solution. This
skilled team will improve your ability to deliver quality power and improve the reliability and
functionality of pumping water and generating electricity.

Recently, Eaton Corporation has successfully automated a variety of systems in the power
generation and distribution industries. Notable projects include:

— Green Mountain Power, Little River Station: Repowering and modernization, including
exciters, governors, automation and protection systems

— Green Mountain Power, Ascutney Gas Turbine: Automation and excitation replacement

— Bureau of Reclamation, Shasta & Keswick: Excitation modernization

— Titan Americas: Plant Automation including SCADA, automation and protection systems

Eaton’s comprehensive technical proposal proves our ability to meet the requirements of the
specification, deliver on the goals of facility uniformity and maintain an aggressive, flexible
schedule through design and construction.

Eaton Corporation hereby offers to provide the services as detailed below, at the prices and on
the terms and conditions exclusively set forth in this offer.

1.1 EXECUTIVE SUMMARY

The following proposal and scope of work has been developed in response to the Request for
Quote and includes the design and procurement of the required protection and control
equipment associated with the Mavel supplied modern turbine-generator equipment. This
proposal assumes the new synchronous generator will be rated at 1226 kW, 4160 V.

To develop the most creative and cost-effective solution that meets the specification provided,
Eaton Corporation is providing a base price, with several options that either improve reliability,
decrease plant outage and downtime, or other recommended system enhancements.

1.2 PROJECT SUMMARY

The existing Jackson Mills Hydroelectric Generation Station is currently under review for
repowering. The scope of work outlined as part of this offer, is limited to the electrical and
control system as part of the repowering and based on the turbine-generator data provided by
Mavel and referenced as part of this offer.

2. ENGINEERING SERVICES SCOPE OF WORK

Eaton proposes to upgrade the Jackson Mills Station using an integrated approach. The basis
for every successful project is sound engineering and design as well as flawless execution.

Revision: 0.0 BA

Eaton’s Generator Protection & Control Group has extensive experience integrating the latest
technologies and systems into a comprehensive and complete design package. Detailed
design drawings specific to each project are developed to provide an integrated drawing set for
all systems and subsystems within the facility, affected by the scope. When required, old
drawings are re-drawn and verified vendor equipment drawings are integrated into an overall
drawing package. Standard borders and drawing numbers provide a seamless cross reference
for all interconnected systems within the facility.

2.1 DRAWINGS

As part of this offer, Eaton Corporation is including engineering drawings of the protection and
control system. All drawings shall be provided in AutoCAD format per industry standards,
Professional Engineer stamping is not required. Drawing submittals and subsequent approvals
shall be provided per the following outline:

— Review Set (Schematics Only)

— For Fabrication (Custom Control Panels, Field Devices, etc.)
— For Construction (To Be Maintained by On-Site Contractor)
— Red-Lines (Copy to be Maintained On-Site)

— Record Drawings

The drawing package below shall be a complete and functional set of drawings for the entire
facility. All drawings from equipment vendors shall be updated and completed with the entire
system information. The drawing package below outline the minimum number of drawings
included as part of the document package.

— AC Metering & Relaying One-Line Diagram

— Network Architecture & Communications Diagram
— AC Three-Line Diagrams

— Breaker/Contactor Control Schematics

— Protective Relaying Schematics

— PLC I/O Diagrams

— Demolition Details

— Cable & Conduit Schedules

— Panel Fabrication & Wiring Diagrams

— Interconnection & Termination Details

2.2 STUDIES & CALCULATIONS

As part of this project, Eaton Corporation proposes the integration of Schweitzer Engineering
Laboratories 700G Generator Protection Relays for the Generators, one each. All protective
relay settings are provided as part of this offer.

2.3 SYSTEM INTEGRATION

This offer includes a comprehensive and integrated automation upgrade for the Jackson Mills
Hydroelectric Generation Station. Eaton Corporation proposes to design, supply and

commission a complete and fully functional generator protection and control package to include
both manual and automatic control modes.

2.3.1 Programmable Logic Controller (PLC)

The PLC will be responsible for overall unit condition monitoring and sequencing. The
principle functions of the PLC include:

— Unit Start Sequencing & Start Permissive Monitoring
— Unit Stop Sequencing

— Unit Mechanical Protection (Alarm, Shutdown & Trip)
— Unit Voltage & Power Factor Control

— Unit Gate Position Control

— Unit Load Control

— Unit & Station Water Level Management & Control

— Automatic Unit Dispatch Control

— Unit & Station Monitoring & Alarm Conditioning

— SCADA System Integration & Point of Control

2.3.2 Human Machine Interface (HMI)

Eaton Corporation's offer includes the programming integration of a comprehensive HMI for
station and unit control and monitoring. The Maple Systems HMI will be responsible for all
station and unit alarm annunciation and logging. The HMI graphics will be developed to
match other owned facilities for operator familiarity.

2.3.3 Voltage Controllers

The new generator (supplied by others) shall be equipped with a brushless excitation
system. As such, it is our recommendation, that our protection and control system include a
Basler DECS 250 voltage regulator. This voltage regulator will be integrated as part of a
standalone turbine control system.

2.3.4 Network Architecture

This solution incorporates high quality, reliable components to provide the Jackson Mills
Hydro Electric Facility with a long lasting cost-effective solution. The hardware listed below
will be incorporated into the turbine control enclosure. The overall strategy is to provide an
automation solution that incorporates modern intelligent devices with existing manual
controls in a seamless package. This strategy significantly decreases the field support
required for the upgrade as much of the existing field wiring will not be touched. I/O is
connected to the central processor over a high-speed copper ethernet based connection
using Allen Bradley’s Ethernet IP protocol.

2.4 TESTING, STARTUP & COMMISSIONING

Testing is limited to individual hardware and components as part of the larger system. The
entire system commissioning is excluded from this offer.
