Frequently Asked Questions (FAQ)

How is the DOMLEC residential electricity bill structured?
A DOMLEC residential electric bill consists of three main components: (1) A tiered base energy charge per kWh (EC$ 0.38 for 1-50 kWh, EC$ 0.44 for 51-150 kWh, and EC$ 0.52 for >150 kWh), (2) A monthly fluctuating Fuel Surcharge Adjustment (FCA per kWh), and (3) A fixed monthly customer standing charge of EC$ 7.50.
What is the 100 kWh statutory VAT exemption for electricity in Dominica?
Under the Value Added Tax Act, residential electricity customers receive an exemption on the first 100 kWh of monthly consumption. Standard 15.0% VAT is charged only on the portion of the electricity bill corresponding to consumption exceeding 100 kWh. Commercial customers pay 15% VAT on their entire bill.
What is the Fuel Surcharge Adjustment (FCA) on DOMLEC bills?
The Fuel Surcharge Adjustment (FCA) is a monthly pass-through mechanism regulated by the Independent Regulatory Commission (IRC). It reflects the actual cost of diesel fuel used by DOMLEC generators, offset by generation from hydro plants in Trafalgar and Padu.
How does hydro power generation affect DOMLEC power bills in Dominica?
Dominica has significant hydroelectric generation capacity in the Roseau Valley. During the wet rainy season (June to December), hydro output increases substantially, displacing diesel generation and lowering the monthly Fuel Surcharge Adjustment (FCA).
What are the commercial standing charges and base rates for DOMLEC business customers?
Commercial customers are billed at a flat base energy rate of EC$ 0.48 per kWh plus the monthly FCA, alongside a fixed monthly customer standing service charge of EC$ 22.00, and full 15% VAT on the entire bill.
