  1. BACKGROUND

 

  1. The Caribbean Community Climate Change Centre (CCCCC) has received grant funding from the Government of Italy under the Italy-CARICOM Project that will support a reduction in the amount of diesel fuel used in the generation of electricity on the island of Dominica and help in the promotion and projection of the island as an eco-friendly destination.

 

  1. This project includes the installation PV systems that will eventually provide the power needed for DOWASCO’s day-to-day operations and provide backup power in the event of a disruption in the grid supply as experienced with almost every extreme weather event. The intention of DOWASCO is to completely eliminate the use of fossil fuel power for the facilities by switching to renewable energy sources

 

  1. The potential for replication is very high and DOWASCO intends to use this activity as a demonstration of the potential for the use of renewable energy sources as part of the greening of its operations and building the resilience of its facilities island wide.

 

  1. THE OBJECTIVE AND GENERAL TASK

 

The Italy-CARICOM Project will work collaboratively with the Government of Dominica through DOWASCO to install solar photovoltaic energy systems with battery support at two water pumping stations, namely, Jimmit/Warner Pump Station and Grand Bay/Tete Morne Pump

Station

 The CCCCC wish to engage the services of a consultant engineer with proven capabilities in the preparation of technical assessments of electrical energy needs and related areas to undertake the tasks outlined below. 

The selected consultant must demonstrate a thorough understanding of and familiarity with the subject matter, and practical experience in the field including the preparation of technical and financial assessments of electrical energy needs of communities.

 

  1. SPECIFIC TASKS

 

Task 1: Site Visit and Data Collection - Estimated work effort is 3 days

 

The Consultant shall conduct a site visit to DOWASCO’s two (2) water pumping stations, namely, Jimmit/Warner Pump Station and Grand Bay/Tete Morne Pump Station

During the site visit, the Consultant shall inter alia:

 

  1. Interview key facility personnel to establish operating characteristics of the facilities, operating and maintenance procedures, unusual operating constraints, and anticipated future expansions or changes to the facility.

 

  1. Inspect and observe the facility in order to map energy use flows and operations;

 

  1. Review all available documentation, including all architectural, mechanical and electrical drawings; and

 

  1. Make necessary field measurements of the following;
    1. Whole facility electricity profile measurement:
      1. Electricity demand measurement for electrical profile at facility electricity service entrance to capture kilo-watt, kilo-Volt-Ampere, Kilo-VaR and power factor at 15 minutes interval;
      2. Electrical energy use for the entire period of measurement.
    2. Profile measurements of all equipment, air-conditioning and lighting circuits to establish operating times and share in the energy and demand distribution;
    3. Conduct electrical spot measurements at other important points within the facilities to establish share of demand and energy use for various floors or sections of the building.

 

Task 2:  Preparation of an Energy Assessment Report - Estimated work effort is 5 days

 

The Consultant shall prepare an Energy Assessment Report that shall include, but not limited to, the following:

  1. Executive Summary.
  2. Introduction
  3. Glossary of Terms.
  4. Facilities analysis.
  5. Description of Existing Water Pumping and Electrical Systems.
  6. Analyses of Energy Efficiency Measures (EEMs) and Renewable Energy Options (REOs) – Specifically Solar Photovoltaic Options;
  7. Recommended optimal size for separate grid-tied PV system with battery storage at both Jimmit/Warner Pump Station and Grand Bay/Tete Morne Pump Station with necessary justifications and supporting analysis. The recommendations shall cover the Full Specifications of the PV systems for each Pump Station, including:
    1. An estimate of the yearly energy output of the system. This should be based on the available solar irradiation for the tilt angle and orientation of the array;
    2. Estimated number and type of PV panels.
    3. Estimated size of the battery bank.
    4. Estimated cost of the PV systems.
    5. Energy yield, specific yield and performance ratio of the grid connect PV systems.
    6. Inverter size based on the size of the array.
    7. Array configuration to the selected inverter maximum voltage and voltage operating windows.

 

  1. Common grid-connected PV system configurations and components as well as considerations in selecting components.
  2. All considerations in design and installation of the PV systems.
  3. Estimated costs and the required expertise to install the PV systems.
  4. Recommended warranty information relating to each of the items of equipment.
  5. Identification of building and electric code requirements.

Appendices (reference data for analysis presented in the report)

Task 3:  Presentation of Energy Assessment Report and Revision - Estimated work effort is 2 days

 

The Consultant will be required to present the Energy Assessment Report to a team of personnel from the CCCCC and DOWASCO by virtual means and make any necessary revisions to the Report.

 

  1. OUTPUTS AND DELIVERABLES

 

The activities undertaken by the consultant will result in the following outputs and deliverables:

  1. Initial Report on the site visit and consultative meeting with officials from DOWASCO and other stakeholders including government officials, the DOMLEC, regulators, etc.

2. Draft Energy Assessment Report.

  1. Presentation by virtual means using a Power Point Presentation that highlights the key recommendations and justification.

4. Final Energy Assessment Report.

 

  1. REQUIRED QUALIFICATIONS AND EXPERIENCE

 

  1. A qualified/registered engineer with related minimum qualification at the level of

Bachelor’s degree; ii.  ≥5 years’ proven experience in PV design and installation;

  • Proven track record in at least three (3) similar PV design projects within the last five years (name and contact information of referee for each previous project must be provided);
  1. Demonstrated Experience in energy efficiency assessment;
  2. National of a CARICOM Country.

 

  1. DURATION AND PLACE FOR PERFORMING SERVICES

 

i. It is expected that this activity will commence on or about October 15, 2019, and end on or about October 30, 2019 and will not exceed ten (10) person days.

 

  1. The Consultant will be required to make one site trip to perform Task 1. Tasks 2 and 3 will be performed from the Consultant’s Home Base.
