TMT Medium Voltage Rate

Optional tariff for the supply of energy and power to medium voltage electrical services and any use of energy, under a contract with a minimum term of one calendar year, extendable for annual periods, the subscriber having to commit to consuming at least 120 kWh per calendar year. If said minimum has not been reached at the time of issuing the billing for the month of December, the necessary energy (kWh) will be added to this billing to complete the annual consumption agreed in the contract, to which the price of energy will be applied in peak period. In the case of electrical services to which this rate is applied for the first time, the minimum consumption for that calendar year will be proportional to the number of invoices issued during that year.

This rate category establishes prices through a band. The values ​​between the minimum and maximum prices can even be applied to the energy and power consumption of the users who can access the rate, as required and after the CNFL has assessed each particular case based on consumption among other variables.

Service features

Supply of energy and power to services served in medium voltage classified as M1, M2, M3, M4, M5, M6, M7 and M8, as specified in article 26 of the regulatory technical standard AR-NT-SUCOM “Supervision of the commercialization of low and medium voltage electricity supply.

In the monthly billing, the company will report, for the invoiced period, the following information related to the quality with which the service is provided:

i. The total outage time.

ii. The total percentage of the voltage outside and within the permitted range according to the standard.

iii. The total percentage inside and outside the norm of the total harmonic distortion of voltage and current.

iv. The power factor.

v. Quantity, duration, magnitude of the gaps and voltage peaks. SEMI F47-0706 curve or updated equivalent.

Tribute to Firefighters

It creates, as a complementary source of income for the operation and sustainable growth of the Costa Rican Fire Department, a tribute equivalent to one point seventy-five percent (1,75%) of the monthly invoicing for electricity consumption paid by each subscriber or direct consumer of electrical energy. The CNFL, as well as all the electricity distribution companies in the country, must collect the Firemen's Tax monthly from December, according to the 8992 law.
The tax of one point seventy-five percent (1,75%) will be applied from the first kilowatt hour consumed and up to a maximum of one thousand seven hundred fifty kilowatts per hour (1750 kWh). Subscribers whose monthly consumption is equal to or less than one hundred kilowatt hours (100 kWh) will not be subject to payment of said tax.
Any institution, company, company or similar that provides the electric power supply service will be the agent of perception of this tax. Every collection agent must transfer all of the money collected directly to the Costa Rican Fire Department, at no cost to the latter within the first ten business days for the total amount of tax collected in the previous month, in the media, the form and the conditions established by the Fire Department. This amount excludes the amount paid for sales tax.

Calculation for Clients

- With Residential Rate

Amount Energy (in colones) x 1,75%

- Non-residential with consumption exceeding 1.750 kWh

(Amount of Energy in colones ÷ total energy consumption) x 1.750 x 1,75%

TRB = (((₡ ⁄kWh) / kWh) * 1 750 kWh) * 1.75%

Public Lighting Cost

This rate must be applied to direct consumers of the Compañía Nacional de Fuerza y Luz, SA in the places, where by contract with the municipalities, take charge of the public lighting.

For every kWh consumed ¢ 0,00

Variable Generation Cost (CVG)

For the rate modification established as of January 1, 2020, a change is made in the methodology, where it goes from Variable Fuel Cost (CVC) to Variable Cost of Generation (CVG).
The CVG is a component of the generation, distribution and public lighting rates that the Public Services Regulatory Authority (Aresep) sets for the Costa Rican Institute of Electricity (ICE) and all distribution companies.
On August 14, 2019, ARESEP through the Energy Administration indicates in official letter OF-0966-IE-2019 that it establishes the procedure to be followed for the correct application of the Variable Generation Cost (CVG) tariff methodology.
In order to obtain the CVG values ​​for each quarter, three variables are taken into account: a) the cost of fuel produced by the generation with thermal sources; b) the amount of the commercialization of net energy in the Regional Electricity Market (MER) and c) the recognition for liquidation of previous periods.

Cost of Value Added Tax (VAT)

It is calculated on 13% of the following items (those that apply according to the rate you have):

Energy, Demand, Variable Cost of Generation (CVG), Variable Cost on Demand (CVD), Provisional Service, Low Power Factor and Transformation Loss; this depending on the colones billed and applies to all customers.

* Residential customers billing less than 280 kWH per month are exempt.
