Objectives of this presentation

1) To present the community-assisted

hydrologic monitoring being conducted forthe proposed Upper Tabuk HydropowerProject in Kalinga, Philippines.

2) To invite the IC-SHP & IN-SHP to becomepart of the development of small hydropower

potential of Kalinga.

Small Hydropower Potential in Kalinga

Modified from Harza, 1993

Tinglayan B:21MW

Pasil B:

20 MW

Pasil C:

22 MW

Pasil D:17 MW

Saltan B:

24 MW

Upper Tabuk:10MW

Including big and micro-

hydropower potential:Around 600MW

Development Challenges

1) Social acceptability concerns

2) No available hydrologic data to establishhydropower generation potential

1.a) Dislocations and claims of unfulfilled resettlement

promises

1.b) Disrespect of/disregard for indigenous peoplesrights and non-recognition of their ancestral domain

1.c) Killings, abductions and torture associated withprevious hydropower projects


6/15

Upper Tabuk Project: IECs and consultations

- Host community permitsthe conduct of a FeasibilityStudy and willingly provides

assistance.

- How about hydrologicmonitoring with communityassistance?

No villages or rice fields to be submerged!


8/15

Hydrologic monitoring

1) Staff gage


9/15

Hydrologic monitoring

2) Rainfall/weather monitoring system


10/15

Streamflow monitoring (1/2)

Community participated inthe installation of staffgage and in actualmeasurements of flow to

derive a rating curve forthe staff gage.


11/15

Streamflow monitoring (2/2)

Staff gage readings recorded using a mobilephone equipped with digital camera.

Conclusions from

the ongoing hydrologic monitoring program

1) The decision to adopt a program with active

participation from the host community resulted not onlyin successfully gathering data itself but also in gainingstronger support for the proposed Upper TabukHydropower Project.

2) The streamflow data obtained through the saidmonitoring program confirmed that a design flow of40m3/s and design capacity as daily peaking plant of10MW are feasible.


14/15

Status of the Upper Tabuk Hydropower Project

1) An ongoing updated feasibility study is being conducted.

2) The Philippine National Commission on Indigenous Peoples(NCIP)-Kalinga Province Office already issued a certification

that the host community is strongly pushing for the development ofthe said project.

3) An environmental examination report has already been drafted

and shall be submitted for an Environmental ComplianceCertificate (ECC).

4) An updated hydrologic study for the application for water

rights/permit is also being drafted.

5) Both private and public parties are now being invited to participatein the development of the Upper Tabuk Project and other potentialsites in Kalinga.
