Geothermal power from Valencia is distributed by the NPC to two (2) electric cooperatives (Negros Oriental Electric Cooperatives I and II), which are mandated by law to implement the rural electrification program in the province.
NORECO I covers the northern municipalities of Mabinay, Manjuyod, Bindoy, Ayungon, Tayasan, Jimalalud, La Libertad, Guihulngan, and Vallehermoso as well as the cities of Bais and Canlaon. The cooperative is based in Bindoy. It operates two (2) susbstations with a combined capacity of 15 MVA. One (1) substation, with a capacity of 5 MVA, is located in Bindoy. The other, with a 10 MVA capacity, is located in Guihulngan.
In 1996, there were already 145 barangays energized out of the 285 potential barangays within targeted for electrification. As a result, at least 22,586 households now have access to electricity. Based on household connections and consumption by commercial and industrial establishments, the peak load of NORECO I was 6,518 KW or about 2,097,995 KWH.
Covering the southern portion of the province, NORECO II supplies electricity to the following areas: Dumaguete City, Tanjay City, Bayawan City, Pamplona, Amlan, San Jose, Sibulan, Valencia, Bacong, Dauin, Zamboanguita, Siaton, Sta. Catalina, and Basay. The coverage area has an estimated 126,165 households in 2000, spread over 272 barangays with a land area of 3,181.25 square kilometers or nearly 59 per cent of the total area of the province. As of 1996, NORECO II was able to energize 194 barangays (71.3 per cent of the potential number) and 50,910 households (44 percent of the potential number).
The Dumaguete-based cooperative gets power from four (4) substations and one (1) hydroelectric plant with a combined capacity of 45.5 MVA. The largest substation with a combined capacity of 30 MVA is located in Pulantubig, Dumaguete City. The other stations are situated in Tanjay, Siaton, Bayawan and Amlan with capacities of 4.2, 5.0, 5.0 and 1.3 MVA respectively. The hydroelectric plant is located in Amlan. Except for the Amlan substation, all threeutilize a 13.2 KV primary voltage and a 7.62 secondary voltage. NORECO’s present capacity is expected to increase with the ongoing construction of a 3.75 MVA substation in Kalumboyan, Bayawan City and the proposed construction of a 20 MVAA substation in Dumaguete City.
