GB Power Company Regulation

Responsible for the power sector in Grand Bahama, and oversight of the Grand Bahama Power Company (GBPC).

What We Do


The Grand Bahama Port Authority (GBPA) is the regulatory authority with responsibility for the power sector in Grand Bahama. Under its regulatory jurisdiction is oversight of the Grand Bahama Power Company (GBPC).

The legislative framework which grants the authority for regulation is set out in both the Hawksbill Creek Agreement and The Operating Protocol & Regulatory Framework Agreement (Regulatory Framework) implemented in 2013. The Agreements establish the GBPA as the independent regulator of the power sector with responsibility to approve the rate structure for the utility and to ensure operational standards are in line with international prudent utility practice, throughout the industry.

Renewable & Alternative Energy


In 2015, GBPC set out to undertake an innovative approach to lowering its system peak demand, and deferring future fossil-based generation investments. The proposed plan includes:

  • The change out of all night lighting to LED technology: The new lights will replace high pressure sodium (HPS) lamps in a move designed to decrease the amount of energy consumed by street lighting on the island. This move is in keeping GBPC’s plan for improving energy efficiency, reducing carbon emissions and the use of fossil fuels.
  • The introduction of Solar PV technology: GBPC recognizes that the use of solar provides benefit to customers, partly by enabling the deferral of future capital investment in fossil fuel generation assets. Solar, when combined with a cost effective energy storage system to capture the sun’s daytime energy, can be successful on Grand Bahama, where we have the ability to release the stored energy during the night when the island’s energy demand is at its highest. Areas being investigated include the East End of Grand Bahama and the Industrial area.
  • Provide customers throughout Grand Bahama with the ability to generate/sell electricity to the grid, using renewable sources of energy, through the development of GBPC’s new Renewable Energy Rider rate. This rate allows for customers to supply energy generated from energy sources such as Solar PV, Wind turbine or other forms of renewable energy to the grid.
  • GBPC has introduced biofuel as a source of energy with the utilization of biofuel in GBPC’s diesel vehicles in January 2016. Initially a 20% biofuel, 80% petroleum blend will be used. Biodiesel will also be used in GBPC’s generation equipment at lower concentrations as the volume of biodiesel produced permits in 2016.

Timeline Indicated in 2015


Legislation


In 2013, a Regulatory Framework Agreement was established for the GBPC. The Regulatory Framework documents how electricity rates will be set for Grand Bahama and how GBPC meets its obligation to provide a appropriate level of service to its customers. The Agreement enables the GBPA to establish Performance Targets and Customer Service Standards against which the utility is measured.

Tariffs & Protocols


GBPC is required to submit an application for rate approval to the GBPA every three years, in accordance with the Regulatory Framework.

The “All-In” rate paid by Grand Bahama Power customers is comprised of two parts:

i) The Base Rate reflects GBPC's operating expenses, depreciation of capital assets, and return on capital investment.

ii) The Fuel Charge is the actual cost of fuel used to generate electricity and is a full pass-through mechanism which generates no profit to the utility.

The Grand Bahama Power Company has four classes of customer tariffs:

  • Residential
  • Commercial
  • General Service Large/Industrial
  • Temporary

Service Standards and Operating Protocols

As part of the established Regulatory Framework, GBPA has authority to establish Performance Targets and Customer Service Standards for the utility. GBPC is required to report to GBPA on the Performance Targets and Customer Service Standards on a monthly, quarterly and annual basis.

The actual cost of fuel used to generate electricity. This a full pass-through mechanism which generates no profit to the utility.

Minimum Charge

The minimum monthly charge is $44.45.


Fuel Charge Calculation

Like many other jurisdictions, Grand Bahama Power recovers the amount it spends on fuel through a Fuel Charge. This is an open, transparent process that is calculated in accordance with a formula approved by Grand Bahama Power's Regulator, the Grand Bahama Port Authority.

The fuel charge is determined each month based on two factors:

  • The actual cost Grand Bahama Power paid for the fuel it is now burning; and,
  • The amount of fuel Grand Bahama Power uses in that month to produce electricity.
  • The total amount (cost x amount used) is divided by the total kWh's used on the island during that month to arrive at a cent per kWh cost (¢/kWh) that is charged to each customer.
  • 2013 Average Fuel Charge: 16.79 ¢/kWh
  • 2012 Average Fuel Charge: 20.69 ¢/kWh
  • 2011 Average Fuel Charge: 20.6981 ¢/kWh

The amount paid for fuel is based on world oil market prices. Grand Bahama Power does not profit from the price or quantity of fuel that it uses.

Efficiency


GBPC is required to report the utility’s heat rate and system losses performance on a monthly basis to the Regulator.

Heat Rate refers to the amount of energy (measured in BTUs) required to produce one KWh of electricity; the lower the heat rate, the greater the efficiency.

Reliability


GBPC is required to report the state and performance of its Generating and Transmission & Distribution assets, on a monthly basis to the Regulator. Additionally, documentation is required to be provided on a monthly and quarterly basis.

Reliability is measured with three indicators: SAIDI, SAIFI & CAIDI reports.

SAIDI means "System Average Interruption Duration Index". It measures the total duration of all power interruptions (in hours) that the average customer experiences during the year.

SAIFI means "System Average Interruption Frequency Index". It measures the average number of times that a customer experiences a power outage during the year.

CAIDI means "Customer Average Interruption Duration Index". It measures the average duration per power interruption that a customer experiences during the year.

Customer Service Standards


GBPC is required to report quarterly to GBPA on the Customer Service Standards. In cases where the utility fails to satisfactorily meet the established service metrics, customers will receive written communication and a subsequent credit on their account.

Customer Service Metrics:

  1. Restoring power after a fault, for a single customer (Target within 12 hours of being reported)
  2. Responding to customer complaints, billing and payment queries (Target within 21 days)
  3. Connect or transfer a service (Target within 3 working days)
  4. Reconnecting service after disconnection at the meter (Target within 1 working day after payment of the bill)
  5. Meter inspection
  6. Meter reading
  7. Meter testing

Note: Monetary compensation is associated with items 1, 2, 3 and 4 if the target service level is not met.
