The HESTIA Technological development

HESTIA project aims at providing a cost-effective solution for the next-generation DR service and one of the initial steps towards achieving this goal was to perform the technical characterization of the pilots and get more insights into their flexibility potential.

The technical characterization was performed from the perspective of existing energy infrastructures and the regulatory context of each pilot country related to the question of flexibility, energy self-consumption and energy communities. After learning more about the properties and constraints of different pilots, the next step was to define the Key Performance Indicators (KPIs) which will be used to measure the effectiveness of the HESTIA solution once it is deployed in the pilots. This evaluation will be made by considering energy efficiency, comfort, user engagement, the economic and environmental impact of the project.

More specifically, the KPIs will help us to better understand the changes in user behavior because of HESTIA and provide guidelines for its future improvements. Based on these KPIs and the data points required for their calculation, the HESTIA consortium has designed a technological platform that will be used to collect and process the data, as well as to interact with external parties (e.g. smart grids) and the end-users.

A platform ready to start collecting data
During this first year of the project, the platform has already been designed and configured to be ready to start collecting the energy, environmental and other types of data from the pilot sites. Regular meetings involving technology providers and pilot sites representatives have been organized in order to devise an initial plan for deployment of new equipment in addition to legacy devices such as smart meters, which are already available in the pilot sites. By installing new equipment, provided by consortium members Develco, NesosNet, Midac, and other external vendors, the pilots will be enhanced to be more flexible in terms of DR resulting in energy savings for both residents and energy providers. Besides, by exploiting the data coming from environmental sensors and allowing users to remotely control their appliances, the comfort of the end-users will be improved.
During this second year of the project, after the equipment has been deployed, the HESTIA platform will start collecting the measurements from the pilot sites, mainly focused on total energy consumption, individual appliance energy consumption, user presence, etc. During this so-called baseline period, the platform will provide the basis for the subsequent validation period, when the HESTIA platform will be fully developed with all data analytic services and user visualization apps running.

Once the validation period ends, KPIs from both periods will be evaluated and compared in order to estimate the benefits of HESTIA and reviewed to identify further ways of improvement.
