The project consists of the construction of PV farms with demonstration hydrogen storage on the brownfields: unused land and landfill. The planned farms are maintenance-free installations. The operation of the PV farm consists of the production of electricity from generators, photovoltaics and conversion to alternating power through inverters. The basic element is the solar panel. The panels will be attached to a steel structure, anchored directly in the ground. Approximately 1600 panels with a peak power of 0.4 kW each are estimated.
The farm will consist of the following: PV panels, internal roads, above-ground and underground infrastructure, energy-fibre cable lines, power connections, inverters, other necessary elements and monitoring. The surplus energy will be stored in a demonstration H2 storage. The stored H2 will be converted back into electricity and sold at a time of higher price or to power the City during the night valley periods.
The mplementation of the investment concept will allow the transformation of a district heating plant, producing district heat exclusively based on fine coal, into a combined heat and power plant that will produce heat and electricity based on RES sources and low-emission technologies.
The implementation of the investment measures will make it possible to achieve approx. 10.5 MWt and 3.5 MWe - power obtained from the Thermal Waste Processing Installation. The estimated amount of biogas produced is 2.8 million m3/year of biogas. There will also be 1.6 mln m3/year of landfill gas obtained. The amount of clean energy obtained from co-firing biogas and biomethane in a gas engine (and also hydrogen in the long term) will be 75,000 GJ/year and 27,600 MWh/year and1.6 mln m3/year of landfill gas will be obtained. Lastly, approximately 25,000 Mg/year is the amount that will be obtained, hydrated, and digestated to be reused in the Waste Incineration Plant Instalacja Termicznego Przekształcania Odpadów (ITPO) installation.
The amount needed to prepare the feasibility study for the construction of an energy complex in Czechowice-Dziedzice may exceed the grant amount. Since the energy complex is at a preliminary stage, the Commune cannot define the source and amount of financing. One of the essential parts of the feasibility study is the financial analysis of the project, which can indicate the possible activities and financial resources to be involved. The development of the feasibility study for the energy complex will allow to set directions for action and indicate the activities needed to complete the investment.
Within the project, it is considered to build the new council office in Dobczyce, accessible and energetically positive and moving to it the head council office from the old building. The plan is also to modernise street lights aimed at energy savings and to establish a building renewable energy development centre. There will be the installing of new renewable energy sources in residential buildings:
photovoltaics, heating pumps and solar panels. The installation of new renewable energy sources in public buildings will be the following: photovoltaics (2 MW), a new photovoltaic power station (2 MW) and the creation of an energy community based on installed renewable energy sources, including software for energy balancing. Metering will also be built, resulting from the conditions of cooperation with the energy system operator.
The investment project plans to use these technologies:
Rumia plans to fully comply with the assumptions of the European Green Deal and achieve climate neutrality by 2050. Work is currently underway to prepare and adopt a roadmap for carbon neutrality (with a 2050 timeline). Taking into account the current situation, especially in terms of energy, two phases of the process are planned: 2021-2030 and 2030-2050, that encompass both private and public sectors. In the first phase, investments will be made primarily on public and private resources, which, after preparatory and analytical work, will mainly require appropriate financial outlays as well as the involvement and consent of individual stakeholder groups.
In the second phase, it’s necessary to develop and implement new solutions based on renewable energy sources, local low-temperature heating networks and the concept of distributed and community energy.

The investment concept will focus on the following actions:
Krosno intends to implement the Green Deal and achieve climate neutrality by 2050. The town works around a development map for carbon neutrality. Bearing in mind these plans, two stages are planned: 2021-2030 and 2030-2040.
Phase 1 will be carried out to simultaneously create components that complement each other within phase 1, but phase 2 will also be built complementarily. Investments will be implemented on public, private, and housing resources, taking into account preparatory and analytical works. They will require appropriate financial outlays as well as the involvement and consent of stakeholders.
Both phases take into account the development of RES and "green" energy islands, hydrogen technologies, or local low-temperature heating networks and the concept of distributed and civic energy. All of these are aligned with the EIB energy lending policy.
The intended technology measures to be financed are as follows:
In Łódź, in 2017, the housing sector had the largest share in the total CO2 emissions (46%). For this project, a hundred municipal buildings in the historic centre of Łódź are chosen for the project. More than half of these buildings are tenement houses from the 19th century that have entered the municipal register of monuments. They are currently inhabited by about 2,600 people. At least 80% of flats have an active coal furnace. Overall, these buildings have a specific architecture, so standard solutions will not be possible to implement.
The assumed activities are the following: 1. Complex thermo-modernization of buildings, renovation of buildings allowing for safe decarbonisation, and the replacing of coal stoves with more ecological methods of heating.
The concept of the city's energy balance is based on several pillars. They will be implemented by the city and municipal companies, depending on the component. The municipal waterworks and sewage system company will implement a part with photovoltaic farm and energy storage, public transport and the re-use of renewed water per Regulation (EU) 2020/741 of the European Parliament and the Council on minimum requirements for water reuse.
Another component, based on cogeneration of heat and energy and its distribution to end users, will be implemented by the municipal heating company. The companies will also provide a financial own contribution at the stage of project implementation. The component related to the construction of photovoltaic installations in public buildings and residents' homes will be implemented by the City of Lubartow, and the financial contribution will come from the city budget and the participants of the task.

The project will aim to develop a coherent concept for the implementation of projects related to the improvement of energy efficiency of public buildings and private buildings and the increase in the use of renewable energy sources in the City and Commune of Radłów.
As part of the action, photovoltaic installations with a total power of 300 kW on four public buildings and heat pump installations for domestic hot water and central heating for 14 public buildings are planned. The project will focus on the thermomodernisation of 15 public buildings and 750 private buildings. The project foresees implementation of energy-saving street lighting in which the modernisation consists of the replacement of sodium lamps with LED lighting (700 light points are planned).
Revitalization of the post-industrial area will result in preparing a recreation center for local residents and tourists, including filling-in of the excavation site with gangue. This will also include the possibility of additional quality of life investments (e.g., charging stations). New energy sources will supply it with clean energy both during investment and running. Project will cover:
The project includes an investment component (by sector). In the residential buildings sector, it is foreseen to construct renewable energy installations for residents, such as photovoltaic panels, heat pumps and biomass stoves. In the sector of Public buildings, the project looks at the thermal modernisation of public buildings. As to sustainable urban mobility, there will be the development of electro- mobility (charging stations, charging points, RES installations for stations, smart city solutions and the purchase of buses. As to Innovative energy infrastructure, there would be the construction of a biogas plant, solar farms and energy storage.
Some of the measures foreseen include thermal insulation of building partitions (15 public and 16 residential buildings) and mechanical ventilation with recuperation (23 public and 16 residential buildings). In terms of renewable energy sources, on both public buildings and residential buildings there will be photovoltaic installations on roofs, wind microturbines, removal of fossil fuel sources, heat pumps with internal installations of the building and Energy management system in buildings. Lastly, as refers to smart grids, software and hardware for the municipal decentralized intelligent energy management system (VMES) will also be part of the measures.
The included measures are: sewage treatment plant-RES powered, new energy sources (wind, solar) ensuring coverage of energy needs for transport, water supply and sewage networks (minimum of 1.83 GWh/y), energy storage battery (>1MWh), use of water & sewage networks as an energy storage, thermal modernization of buildings, coal to heat pumps and old cars to e-vehicles.
Wrocław has the largest system of waterways in Poland. The assumption of the project is to reduce the share of cars (individual transport) in the overall transport in the Wroc Agglomeration area, in favour of environmentally friendly water transport. At the present stage, the communes of Wroc Agglomeration are making plans for the water tram routes to be served by vessels powered by alternative fuels, with electric propulsion, e.g. solar energy or using other innovative and pro-ecological solutions contributing to energy savings and reduction of CO2 emissions. The development of zero-emission transport is particularly important from the point of view of environmental protection, rationalization of the demand for parking spaces, the accessibility of collective transport for residents, and the reduction of traffic flow, including from suburban areas.
The planned investment will cover: monitoring the environment outside the building and indoor (temperature, pressure, humidity, air quality, sunlight, sound pressure); measurement of the consumption of electricity, water, thermal energy, RES production; control of the heating and electricity consumption, air quality, ventilation; protection against flooding and fire; provision of indoor communication; display and store of the data; registration of cameras and intercoms. The system will take care of appropriate conditions in individual rooms, taking into account both internal / external conditions. It is planned to prepare mechanisms for monitoring energy measurements, search and automatic monitoring of exceedances or deviations from the norm, which will allow to obtain an image of how energy is used, where savings can be found and it will be possible to monitor the condition of the rooms that affects the efficiency of users, as well as their health in the longer term.
The development of the concept aims to attract investors for the investment (191 million €), a much higher sum than the city’s annual investment budget (39 million €). Apart from CO2 reduction and sustainable energy development, the project will improve the life quality of 108 561 residents, also by smog reduction (PM 2.5 dust emission - 50th place in the EU according to IQ Air, 12th place in Poland among 66 cities with the worst air quality), city functionality and will relieve the budget, enabling further act. Some measures envisaged are:
