Country: Solomon Islands
Project ID: SP-LUN-EU-0322
Project Name: Old Lungga Electrical Upgrade Project – Detail Design, Procurement Support & Construction Supervisions
  1. Background and sector context:
    The Solomon Islands Electricity Authority (SIEA) now trading as Solomon Power (SP) is a vertically integrated state owned enterprise that owns, maintains and operates the national electricity grid in the Solomon Islands.  SP generates, transmits, distributes, sells and regulates electricity in Solomon Islands.The majority of the SP assets are located in Honiara on the island of Guadalcanal, the capital of the Solomon Islands. SP’s electricity networks are largely concentrated in ten town centers serving the main urban/industrial areas on each of the eight (8) major provinces.  They include Guadalcanal Province (Honiara) as noted above, Western Province (Noro, Munda, Gizo and Seghe), Malaita Province (Auki and Malu’u), Central Province (Tulagi), Makira Province (Kirakira), Temotu Province (Lata), Isabel Province (Buala) and Choiseul (Taro).The largest electricity network in the Solomon Islands (both in terms of geographical coverage and in electricity sales) is in Honiara, with a maximum demand of approximately 16 MW.  The main generation plant for Honiara is located at Lungga, about 10km from the Honiara CBD.  The Honiara network consists of- Diesel power stations at Lungga and Honiara (34.2MW installed capacity)
    – 1 MW Solar farm at Henderson
    – Five 33kV feeders interconnecting the power stations and substations
    – 33/11kV substations at Lungga, Honiara, Ranadi, Kola’a, Honiara East and White River.
    – Thirteen 11kV distribution feeders

    A significant program of capital investment in generation, network and distribution infrastructure is planned over the short to medium term to improve power system economics, reliability and security of supply.    Such investments have long-term economic and financial implications for the SP and energy consumers, given the long asset lives involved. Lungga Power Station Electrical Upgrade is part of this investment.SP has identified need for assistance from engineering consulting firms to complete detail technical engineering design for reinforcement/upgrade of Lungga Power station.
  2. Objective of the study and deliverables for this assignmentThe purpose of this study is to do a detailed design for replacement of existing 11kV and 33kV switchgears and associated equipment including protection/control/metering, AC/DC supplies, auxiliary transformer supplies for generators in the old Lungga power station and provide procurement & construction supervision support. The electrical upgrade should allow for prudent operational and safety standards while enabling regular maintenance and higher degree of plant reliability and security of supply for both current and future load growth.The scope of the study includes;2.1. To do a detailed design (based on concept design to be provided to winning Bidder) including but not limited to the following final detailed design items:a) Proposed detailed Site layout drawings of the Lungga switchgear electrical works.
    b) Proposed detailed equipment layout/panel layout drawings.
    c) Proposed Single Line drawings
    d) Proposed Protection, control and metering scheme and Single line drawings
    e) Proposed SCADA systems and interface to fit existing and proposed systems.
    f) Proposed earthing layout
    g) Proposed building layouts
    h) Proposed civil works/layout/plans
    i) Proposed building to house the electrical equipment with full air-condition system
    j) Detail staging of works plan including contingency measures during construction to minimize major outage of power supply to Honiara.
    k) Detail program timeline for the construction of works, scope of works and technical specifications to be utilized by the installation Contractor.
    l) Detail cost estimates for the complete upgrade of the entire 11kV and 33kV switchgears and its auxiliary systems within the old Lungga power station to an accuracy of Plus/minus 20%.
    m) Details of future interface to fit for purpose of incorporating for 2 X 66kV lines entry.
    n) Proposed system to be equipped with fire alarm system capability
    o) Proposed SCADA system to have adequate storage capability
    p) Proposed system to have duplicate protection relays (from separate vendors – Preferably SEL & Siemens) for all step up transformers and 33 kV feeders
    q) Proposed system circuit breakers shall be rack able and preferred to be Schneider or ABB make
    r) Proposed building layout shall have adequate space for carry out operation and maintenance/replacement works
    s) Proposed system shall have spare panels at 11kV and 33 kV for future requirements2.2. Detailed design should include at minimum a detailed earthing study report, fault calculation/analysis/update on the existing DIgSILENT model, protection coordination report, insulation coordination studies, integration report between the old and new Power Station. Detailed earthing study should consider separate grid as well as bonding to the existing taken into account current and future (Tina 66kV reticulation) fault levels.
