City of Lisbon pilots automated demand response


New Energy and Industrial Technology Development Organisation (NEDO) has signed a Memorandum of Understanding (MoU) with the National Laboratory for Energy and Geology of Portugal to implement a demand response project.

Following the signing of the MoU, NEDO has reached an agreement with the city of Lisbon to test its automated demand response technology in facilities owned by the council.

The project is also being implemented in partnership with Portuguese electric power retailer and a Virtual Power Plant operator, who aggregates multiple small-to-medium power generation facilities of renewable energy.

The solution provider is partnering with Daikin to deploy the technology to remotely manage power demand and usage in four public facilities including the City Hall.

NEDO and Daikin have installed multi-split air conditioning systems equipped with cold storage units and a demand response function.

The cold storage system will be used to provide air cooling capabilities to air conitioning systems, a development which would help reduce energy usage of the air conditioners during times when demand is high.

The solution includes a system consumers can use to predict daily energy use based on available data on weather and daily air conditioning patterns.

The platform will remotely switch appliances’ energy demand in line with signals sent by the grid operator of the VPP.

The aim is to reduce consumer bills during peaks, ensure grid reliability and to maximise renewable energy usage during peak demand periods.

The ADR system had been in development since 2016.

The pilot launches at a time commercial buildings account for approximately 40% of the country’s total electricity consumption.

Portugal is also in the process of expanding its renewable energy generation following powering 44% of its domestic consumers with renewables in 2017.
