REC-A will become the springboard to propel the energy transition across the municipality. Through PV and ESS assets installed in public, residential and industrial building, the project will increase the share of renewables consumed and the energy efficiency of the municipality. PV and ESS assets will be installed in public, residential and industrial buildings. In public buildings, energy efficiency measures will be put in place (i.e. envelope retrofitting, replacement of HVAC assets), adding also a layer of intelligence (i.e. sensors, actuators, BMS, etc.). Likewise, energy efficiency measures and PV retrofitting in the industry will take place, after removing asbestos presence on rooftops. Besides, a community battery will be installed to provide flexibility and enable the community to participate in the Spanish ancillary services market. Actions on urban mobility will be also deployed: EV charging points, new EV/HEV float, etc. Also, logistic centres will be created to facilitate charging infrastructure towards 100% electric “last mile” delivery.
This investment concept will be about renewable electricity generation, using solar photovoltaic, low wind and small hydro technologies. All energy resources are available within the municipality. For photovoltaic energy, the roofs of municipal buildings, industrial buildings and residential buildings are used. The other measures are as follows:
The project aims to reduce 40% of GHG emissions (baseline year 2019) through these measures.
The purpose of the project is to transform the way citizens access energy, encouraging the production of renewable energy, electric mobility and efficient consumption. It seeks to develop an investment concept for different energy efficiency actions. For example, Smart Energy Communities will be created with photovoltaic installations (in municipal and private facilities) for collective self-consumption. The plan is to analyse the possibility of sustainable mobility (strategic charging points, change of municipal and private fleet), and district heating with 100% renewable models. They also wish to look into a technical analysis of wind and biomass capacity in the region, among other measures to be considered.
In Lleida, the investment concept will delve into the refurbishment of the most inefficient neighbourhoods’ areas. Measures that would be foreseen are the following:
Implementation of low-cost energy-saving measures in neighbourhood communities (LED, remote energy management, programmers…)
The concept will finance PV installations on suitable public parking areas and municipal and residential rooftops within the city. The aim is to consume as much generated solar power as possible at a local level for 1) cooling and heating in residential communities and municipal buildings and 2) powering (public and private) electric vehicles. This significantly extended solar power generation enables the implementation of a smart grid management system together with demand-side response measures. This investment guarantees adequate management of demand and supply and the maximization of local clean electricity consumption.
Charging of electric vehicles will be incorporated with incentives (e.g. free charging during peak sunshine hours), contributing to the stability of the grid. The transformation of the mobility sector and a shift towards consuming clean electricity will come after supporting the purchase of electric vehicles for both citizens and the city.
Development and implementation of photovoltaic solar parks on municipal land, which use the Power Purchase Agreement model for virtual self-consumption. The targeted sector is Building integrated renewables.
The following measures are foreseen to set up a local energy community (LEC) in the municipality to develop a set of actions to improve energy efficiency and reduce local energy demand. They foresee the installation of solar PV integrated with public and private buildings to reduce their demand and share with others. Also, they will install solar PV in the municipal grid (or closest grids) to benefit the overall municipal RES production, reducing local energy demand, improving grid efficiency and supporting the smart city concept. These two PV installation measures are the basis for the Local Energy Community, including social and environmental benefits. There is also the aim to renovate 10,000 m2 of public buildings to reduce their energy demand, an average of 50% energy savings reached and increase the Electric Vehicles fleet by 75 more vehicles in the municipality. They also plan to install 1,000 LED luminaries in streetlighting with sensors, aimed at reducing on average 60% of the electric demand.
Measures involve substantial building renovation to achieve significant energy efficiency (EE) improvements with a user centred approach sensitive to user motivations (which tend to focus more on health and wellbeing than on EE). Targeted sectors include Building integrated renewables and Residential buildings.
Under the Energy Transition and Climate Change Strategy (ETEyCC2030), Pamplona will replicate successful models for RES integration in buildings to build Positive Energy Districts (PEDs) triggered by local energy communities based on energy efficiency, local renewable energy generation embedded in Smart Districts, energy flexibility and sustainable mobility.
Solar energy communities and biomass district heating will be the main sources for electricity and heating in PEDs. Internal mobility will be reduced and EV infrastructure will be implemented based on PV generation. PEDs are included in the 2030 Urban Agenda, which includes the ETEyCC2030, ensuring energy aspects are integrated into urban planning.
One-stop-shops will be set up in the PEDs after the experience of the EFIDistrict project to ensure the involvement of citizens, business and public sector for the uptake of innovative mixed financial schemes, being the Municipality the driver and multiplier of local energy investments.
Rivas GEC is the tool to move on towards the positive district concept. The project aims to increase the share of renewables consumed, as well as impact the overall town energy efficiency. PV generation and energy storage assets will be installed in public, residential and industrial buildings. In public buildings, energy efficiency measures will be put in place (i.e. envelope retrofitting, replacement of HVAC assets), adding also a layer of intelligence (i.e. sensors, actuators, BMS, etc.). Likewise, a community battery will be installed to provide flexibility and enable the community to participate in the Spanish ancillary services market. Actions on urban mobility will be also deployed: EV charging points will be installed, new fleet of EV/HEV buses, etc. Together with an aggregation management platform to handle the assets and optimise the community performance, a retailer in the form of a cooperative will be promoted by the municipality to act as a market agent on behalf of the Rivas GEC.
The energy rehabilitation of residential buildings (detached and semi-detached houses, and apartment buildings) will comprise the improvement of the building skin insulation (Exterior Insulation and Finish System (EIFS), cellulose injection, double-glazed windows, thermally broken window frames, etc.).
The project will also look to increase the efficiency of the energy production systems (such as high-efficiency heat pumps) and the implementation of renewable energy systems (photovoltaic installations for individual or shared use). Furthermore, photovoltaic installations will be built on all municipal building roofs, when technically possible, to provide renewable energy for the municipality's consumption and share the energy surplus with residencies which lack enough surface to fulfil their demand for renewable energy.
