This paper describes the development of a new power standard based on a commercial thermocouple sensor. A calibration with a twin microcalorimeter has been performed in order to determine the effective efficiency of the sensor. A calibration using thermal transfer allows us to validate the results got with the microcalorimeter. LNE has got a new power standard for low frequencies.
