What is the hourly residential rate?

It is an optional fee, designed for the residential sector, which suggests an efficient administration of electric power. It is sought that, through certain consumption habits, the customer may have a decrease in the amount of their bill, without having to reduce the use of their appliances or electrical equipment in general. For this, different prices of electric power are established for different periods of the day, that is, during certain hours, the electric power will have a lower price than during others.

How do I calculate my consumption?

When you receive your electric bill, remember that the amount to pay for electricity is based on the number of kilowatt-hours (KWh) consumed monthly and other factors that we describe below: Number of days invoiced: The number of days invoiced corresponds to the period during which the electric service was provided and that must be charged by means of the corresponding invoice. The variation of days invoiced per month is due to the internal programming that the CNFL establishes in order to be able to cover, during the calendar month, the totality of the clients to whom it provides the service. The collection periods may be between the 28 and 32 days. This represents a variation of consumption between one month and another. Sales tax: An 5% is charged in the residential tariff on the cost of the energy consumed, provided that the electricity consumption exceeds 250 KWh per month; and an 13% in general rate. Public Lighting: A specific amount for each KWh consumed is charged for this concept (see rate schedule for more details). The electricity bill is structured by blocks of consumption, with different prices for each block, following the principle that the higher the consumption, the higher the price. Hence the importance of using electrical energy rationally. How do I read my invoice? Please refer to the main menu in the link Interpret your Residential invoice

What should I do?

The CNFL processes claims for damages in equipment and electrical devices and will be liable for damages that cause its legitimate or illegitimate operation, normal or abnormal, except force majeure, the victim's fault or the fact of a third party.

What is the adjustment to the guarantee deposit?

In accordance with the 8 and 9 articles of the electric contract that our subscribers sign when requesting a meter:

Eighth clause

Deposit of Guarantee:

To guarantee the payment of the service, â € œTHE COMPANYâ € will require its new subscribers a deposit in guarantee equivalent to a monthly invoice, according to the rate in force according to its category. This deposit will be returned to the â € œABONADOâ €, in case you renounce the service and are up to date with your obligations for the electric service. While there is no real consumption, â € œTHE COMPANYâ € will initially charge a provisional guarantee deposit, based on the consumption estimation table according to charges detailed below:



Connected Load (Watts) Estimated monthly consumption (kWh)
Between 0 and 12.000 Declared 2.5% of declared load
Greater than 12.000 Declared 2.5% for the first 12.000 watts, plus 20 kWh for each 1000 watts of connected load

Frequently Asked Questions about Electric vehicles

How do you charge the batteries of electric vehicles, can they be recharged several times during the day without affecting them?

These batteries are charged through the electrical network and can be recharged in the houses themselves. There are different types of batteries and it is a technology that is rapidly modernized, which allows a greater displacement, less size, less weight and lower cost. For example, one of the characteristics of lithium batteries, is that they lack memory effect, so that charges can be made even when the battery is not fully discharged.

What is fast charging, slow charging and electric stations. Where can I recharge?

There are different types of load depending on the user's need for charging. A slow charge is made by a single-phase alternating socket, similar to the domestic outlet (usually 230V and 15A; for a vehicle of 25 kWh: 7 hours of charging). If you need to recharge in short periods of time, this will be done through a three-phase alternating socket (usually 400V and 63A; for a vehicle of 25 kWh: 1 charging time). There is currently a third type of load, which is done through direct current (usually at 400V and 600A; for a vehicle of 25 kWh: 6 minutes). Electrolineras are the infrastructure required for rapid recharging of electric vehicles in Costa Rica. The CNFL plans to install a network of “electrolineras” for fast charging in public spaces in San José according to the demand for this service.

When is it efficient to recharge an electric vehicle?

The CNFL recommends using the Residential Time Rate and recharging overnight at home. This allows the required electricity to be cheaper and the electrical system to be more efficient by minimizing the impact on the electricity grid, since the electricity demand decreases considerably. If it is necessary to recharge during the day, you should try not to load the vehicles at peak times (from 12: 00h to 14: 00h and from 18: 00h to 20: 00h) where the energy demand "shoots up" and is of higher cost.

What autonomy does this type of vehicle have?

The range of travel of vehicles that are currently on the market, is among the 80-110 km of autonomy. The vehicles that are scheduled to start commercializing in mid-late 2013 have autonomies between 160-200 km.

Can you replace an electric vehicle with a combustion vehicle?

In most cases it is possible, the replacement of the conventional vehicle with the electric one will not be any inconvenience because the average distance of the private vehicles is 31 Kms. Of daily displacement in the GAM. A large percentage of society travels daily from short distances (trips to work centers, supermarkets, study centers). It is only a change of mentality and to replace the fact of going to the "gas station" by plugging in the vehicle at night when arriving at the house. Only in very specific situations the vehicle is used to make long distance journeys, in which case there are other alternatives (hire rented vehicles, for example) and, in due course, the public electric vehicle recharging network will be expanded as in other markets.

What are the differences between electric vehicles and hybrid vehicles?

Electric vehicles are those whose only source comes from batteries that are driven solely by the electric motor instead of the traditional internal combustion engine. They use electrical energy supplied by rechargeable batteries that send the developed power to the motor through a controller. On the other hand, hybrid vehicles can be driven to a greater or lesser extent, depending on the type of hybrid that is, by the electric motor or the thermal engine, for which it requires traditional fuels with negative implications for the environment.

How many means of electric transport are there now?

Within the diversity of technologies, there are some types of electric transport such as boats, airplanes and land vehicles such as motorcycles, tricycles, bicycles, support for people with reduced mobility, such as electric wheelchairs, golf carts and one-person vehicles, there are also Massive electric transport (train, metro, tram or trolleybus).

Are electric vehicles more expensive?

Currently, using electric vehicles implies an initial investment higher than that of conventional vehicles and many governments strategically and integrally encourage the use of vehicles in different countries to accelerate industrial development within the framework of the new ecological requirement, to create new jobs and to support the purchase of cleaner cars with lower polluting emissions, they also support research on new technologies and spreading innovation. Operating and maintenance costs are significantly lower in electric vehicles, which is a significant advantage over internal combustion technology. Electric vehicles have no maintenance costs for oils, or other lubricants, less filters, less brake wear and absence of mechanical transmissions among other maintenance benefits.
