TRANSMISSION UPGRADES – EGS TO WASILLA

• Provides reliable power from EGS to the heart of our service area

• Supports significant commercial and residential growth

• Provides reliability and redundancy to vulnerable system

MEA TRANSMISSION UPGRADES

Phase 2: Hospital Substation to Herning (Wasilla)

• Supports significant commercial and residential growth in Wasilla

• Progress stalled due to Wasilla Planning Commission decision

• Interim step – build transmission to LaZelle substation

• MEA working with stakeholders on alternate overhead routes

OTHER SYSTEM UPGRADES – A FOCUS ON RELIABILITY Substation improvements –

• Reduce outages, improve power quality, account for growth

• 5 substations currently undergoing upgrades, including Parks (Chugiak)

Clearing to reduce outages

• Chugiak/Birchwood

• Willow to Talkeetna

New meters

• More accurate bills

• Reduce outage time

• Improve efficiency of workforce

MEA LONG RANGE PLANNING Development of a comprehensive growth and maintenance plan

• Proactive assessment of current system compared to projected growth

• Coordination with other planning efforts at MoA and Mat-Su Borough

• Several new substations identified, including Powder Reserve (N Eagle River)

• Will likely result in the purchase of corridors and substation property for future use

• Target completion: Summer 2015

EKLUTNA GENERATION STATION Online Early 2015

DECISION FACTORS LEADING TO EKLUTNA GENERATION STATION (EGS)

13

• 2004: 10-year notice to Chugach that MEA would not be customer after Dec. 31, 2014 • MEA Integrated Resource Plan, MEA power supply studies, Technology Evaluation Report • Financial and hourly dispatch modeling • Load-flow study, pooling studies • Conversations with Chugach and ML&P on joint effort Other considerations

o Railbelt generation suite o Lack of meaningful work between 2004 and 2009 o Cook Inlet fuel situation o Pipeline configuration o Air regulations o Load characteristics

EKLUTNA GENERATION STATION DESIGN

14

• 171mW Capacity (Ten 17.1mW engines)

• Dual-fuel (Natural gas & diesel)

• Reciprocating engines o Efficiency over power range

• Why Wärtsilä? o Industry leader o 10 smaller engines to better follow our primarily residential load o Proven and efficient technology o Price

EGS COMMISSIONING PLAN

22

• Commissioning agent - Universal Energy, Inc. • Plan for testing, verification and power

delivery • Commissioning dispatch agreement with

Chugach Electric signed • Filling of liquid fuel, oil, coolant, and ammonia

tanks scheduled • Goal -

oFour engines online December 31, 2014 oAll 10 engines online Spring 2015

IMPORTANT COORDINATION WITH RAILBELT UTILITIES

23

• Interim sales agreement with Chugach Electric signed for Q1 2015 • Coordination for power produced during commissioning • Interconnection agreement necessary – EOC stop work order • Complete control communications loop – Eklutna Hydro, EGS, Plant 2

(ML&P), Teeland Substation (Chugach)

• Agree to a plan to capitalize on new opportunities for economic dispatch of power for significant savings

IMPACT TO MEMBERS • EGS transforms the way we serve our members.

• Increased control over decisions that impact our membership.

• Allows us to more closely and efficiently serve our load.

• Projecting an initial rate increase (15-20%) over the next 18 months oLargely driven by new, more expensive gas contracts oProjections were for a similar increase with Chugach, but one year

later.

ROLE IN THE RAILBELT ENERGY PICTURE

25

• 10 smaller engines for load following

• Dual-fuel in case of natural gas supply interruption

• Improves grid stability throughout the system

• Can help integrate variable power

• Component of a single transmission operator and economic dispatch

• May help meet proposed EPA regs by offsetting less efficient generation

CURRENT RAILBELT ISSUES Infrastructure Problem o Inadequate transmission systems o Solution - Upgrade and construct new infrastructure

New generation facilities o 5 new facilities on the Railbelt o Solution - Single, economic dispatch of power

New organizational structure o 6 vertically integrated utilities o Solution - Single transmission operator (TRANSCO)

26

RAILBELT UTILITY NATURAL GAS CONCERNS

27

• Current market is 200 bcf per year. Too small to encourage exploration.

• Inadequacy of current gas infrastructure o Mismatch of supply delivery

infrastructure with demand centers o Long and vulnerable distribution

system o Limited and expensive storage

• Transport costs and ownership

ARCTEC – A CONSORTIUM OF RAILBELT UTILITIES

28

Prioritizing upgrades to fragile Railbelt transmission infrastructure • Support for infrastructure development plan • Funding options limited

TRANSCO/ISO development • Goal – coordination of assets for benefit of the entire Railbelt • Identify best model for Alaska • Feedback from other stakeholders (Legislators, IPP’s) • Legislative $250k to RCA at ARCTEC’s request

MEA IN THE COMMUNITY • Involved in events and organizations throughout our

service area

• MEA Charitable Foundation supports service area with approx. $125K annually from Round Up funds

• Award $20,000 in scholarships annually to area youth

ENERGY EDUCATION (K-12) • The Energy Hog teaches our youth about energy efficiency.

• Safety City presentations educate youth on safe practices around electricity.

• MEA offers school visits, tours and presentations

• AK EnergySmart Curriculum – Energy Efficiency lessons for K-12.

THAT’S ALL FOLKS.
