1. Geography
Chuuk State
5 regions within the State:
3 within Chuuk lagoon;
N. Namoneas; S. Namoneas; Fainchuk
2 outside Chuuk lagoon:
Mortlocks; Northwest
40 Municipalities:
N. Namoneas – 3
S. Namoneas - 5
Faichuk – 8

CPUC – Current Systems (1)
Main grid – 1 island;
7.8 MW installed Diesel (5 units)
0.265 MW installed Solar – US$4.30/W
System peak – 2.8 MW; Avge – 1.8 MW
Solar Contribution – 2.5% of generation

5. CPUC - Workingfor a Brighter Future
CPUC – Current Systems (2)
Stand Alone Systems on schools and dispensaries – 11 islands 12 systems
Total installed solar capacity 90.5 kWp size range 3.4 kW – 13.7 kW
Systems include:
Solar panels;
Lead acid batteries;
Charge controller;
Inverters;
Principal issues:
Land ownership: sites must be on Government land or land with long lease in place;
Buildings must be in good condition;
O&M logistics: 7 within lagoon – 1-2 hrs by boat;
5 in outer islands – 24 -36 hours by boat

6. CPUC - Workingfor a Brighter Future
Chuuk State Resource Assessment
Solar PV:
Latitude 7 degrees north avge. irradiation 5.4 kW/m2 – good solar resource;
Wind:
test data at 2 sites within lagoon – 4.2 m/s avge – poor wind resource;
Hydro:
No large resource available;
Possible mini hydro in the volcanic lagoon islands - low kW range; no
assessment yet undertaken
Ocean energy:
Technology not sufficiently tested;

Chuuk State RE Targets
Chuuk State Energy Action Plan (part of FSM National Policy) Target –
30% RE generation by 2020;
RE Options for Chuuk State currently only solar;
CPUC has concerns that this level of RE generation may increase the cost of power to the
customer on the main island – integration of battery storage will be necessary.
On islands with no power the extra over cost of achieving the target is looking like it will be
cheaper than current costs spent on energy – kerosene lighting; diesel generation etc.
The spread of RE may be greater in currently unserved islands – 80:20 mix in hybrid systems
and 100% in SHS may mean 30% target is achieved without the need for storage on the main
grid

8. CPUC - Workingfor a Brighter Future
Expansion – Types of System
Three different models are under consideration dependent on the spatial layout of
each municipality:
Main grid Main Island; Plus 2 or 3 other large islands – maximise
Solar PV without storage
requires reasonably closely/densely located loads
Mini-grid Solar/Diesel/battery hybrids typically in Municipalities
with Greater than 100 Households - may have a small
number of mini-grids in a municipality due to spatial
and topographical layout of the area
Solar Home Systems Municipalities with less than 100 households;
dispersed homesteads etc.
stand alone systems will be provided on public
facilities – schools, dispensaries, municipal offices etc.

Expansion Challenges
Challenges
Land ownership;
Differential service quality – cost defined;
High Funding requirement – initial estimates around US$65m;
O&M across widely dispersed systems;
Implementation capacity – National government EA/IA;
Mode of distribution – overhead vs underground

10. CPUC - Workingfor a Brighter Future
Models & Mechanisms
Approaches currently under consideration:
Within Chuuk Lagoon
Northern Namoneas Main island – Grid system; Fono & Piis - SHS
Southern Namoneas IPP for grid systems
Faichuk Mini-grids & SHS;
possible cable connected system from main island
with distributed RE/battery systems;
Outside Chuuk Lagoon
North West Mini-grids and SHS
Mortlocks Mini-grids and SHS
