MAXIMETERS (Non-BT5 Clients) 

What is the difference between a Non-BT5 and a BT5 client?

  • A non-BT5 client may hire power above 20 kW. According to the rate, charges for even two powers and two energies are billed. The energy can be supplied in low tension (220 volts) or in medium tension (2.3kV, 10 kV or 22.9 kV). 
    An electronic meter will be needed in order to read active and reactive energy and power.
    A BT5 client can hire a 20 kW power as maximum, paying only for active energy consumption. The energy will be supplied at 220 volts.
  • BT5 clients have electromagnetic meters customized for their use.


Non-BT5 Client: Has binomial billing (energy and power). According to the rate chosen, active energy (up to two energy supplies: in peak hour and off-peak hours), reactive energy (if it exceeds 30% of the active energy) and power (up to two power supplies: in peak hours and off-peak hours) will be billed.

What are the requirements for the installation of a maximeter?

  1. Document proving ownership of the premise (original and a legalized copy).
  2. If you are a tenant, provide the owner’s legalized written authorization. 
    Copy of the identification document (natural persons) or copy of your R.U.C. (legal entities). 
  3. Location plan or simple freehand scheme. 
  4. Reference of neighboring supplies (front, right, left). 
  5. Electrical distribution plan signed by an electrical engineer, member of the Professional Association of Engineers. 
  6. List of machines or equipment to be installed, indicating power in kW o HP. 

How long does the connection of a maximeter take?

What is the difference between kW/h and kW and how much do they cost?

  • kW/h is the measurement unit of energy consumption and it is equivalent to one kW of absorbed power during one hour.
  • kW is the measurement unit of the absorbed power.

For example: A light bulb of 0.1kW (100 W) power used for 10 hours will result in a 1kW/h consumption to be billed.
KW/h price depends on the client’s rate.

Who is considered as a low and medium voltage client?
A Low-voltage client has a tension level of 220 volts.
A medium-voltage client’s supply is fed by a tension level of 2,3kV, 10 kV or 22,9 kV, in which case a ground plant is required to transform it to low voltage.

Why do I have a low voltage meter if I have a Medium voltage rate?
The client and the Dealer agree upon low voltage measurement for medium voltage clients. This is advisable to prevent the measurement equipment from being far from the feeding point, in which case, a charge for transformation losses amounting to 2,5 % of the energy consumed would be added.

How much does the electronic meter cost?
The electronic meter costs S/. 3.350,00 (I.G.V. included)
Connection or adaptation charges must also be considered.

What is the difference between an A1R and an A1R-AL meter?
Both are electronic meters and store the necessary information for non-BT5 reading.
The A1R meter records energy consumption and the maximum demand read.
The A1R-AL meter also allows obtaining load diagrams or profiles at predetermined intervals.

Load Diagram: It indicates consumption and power variations registered in the client’s supply at predetermined intervals. It is useful to determine the client’s rating and provides better criteria to choose a new rate.

What is the Hired Power?
It is the power subscribed by the client and the Company for a maximum allowable charge delivered to the premise.
The client must refrain from using a power above the one hired, otherwise he/she shall be subject to supply disconnection citing that the client is putting the company’s facilities at risk.

What is the Maximum Demand?
It is the average value of the maximum powers recorded by the meter at 15-minute intervals in a specific period (one month).

Why do I pay the Maximum Demand if my power supply has been cut off?
In conformance with Resolution N° 024-97 P/CTE, billing of power charges depends on the Supply Contract, regardless of energy consumption, even if it is null.
Furthermore, article 178 of the Law on Electrical Concessions establishes that binomial-rate supplies which record no consumption are subject to fixed charges for power hired during the contract term, in addition to the monthly fixed charge.

Why isn’t the monthly absorbed power billed?
The billing of demand is broken down in two categories, according to the contract:

  • Hired Power: It considers a steady fixed charge that applies during the whole contract term, regardless of the monthly absorbed power. 
  • Variable Power: The bill amount is the average of the two maximum demands registered during the last twelve months, including the billed month. 

How is reactive energy billed and where is it generated?
Reactive Energy is billed if it exceeds 30% of the total active energy consumed during the month. Only excess will be billed.
Reactive Energy allows la xxx generación de un trabajo and is originated in electromagnetic induction machines (motors and transformers).

What is a Condenser Bank?
It is a system that absorbs reactive energy generated in the motors and transformers, thus reducing their consumption. Likewise, it allows cost reduction of the reactive energy bill. Additionally, it protects the Dealer’s networks against excessive reactive energy flows.
