Energy
Approximately one-quarter of the energy price is owed by the transportation of the energy. The implementation of a local energy system can shift the energy production from a centralised system to a decentralised system.
Affordable And Clean Energy
Industry, Innovation And Infrastructure
Description
Local energy systems are effectively controlled by local shareholders or members, generally value- rather than profit-driven, involved in distributed generation and in performing activities of a distribution system operator, supplier or aggregator at local level, including across borders. The term encompasses both the organisational and technological elements required.
The implementation of a local energy system shifts energy production from a centralised system to a decentralised system. In a local energy system, the energy is produced close to where it will be used, in contrast to a centralised energy production system or a national grid where the production is centralised. The local generation reduces the transmission losses and is able to adapt to the local needs. The system includes generation, storage and consumption of energy. To optimise energy consumption, a visualization of the consumption or controlled energy consumption is possible. Local energy systems can also promote civic engagement, allowing people to actively participate in energy-related decision-making. And as renewable energy sources, such as wind and solar, are usually more decentralised than traditional power sources, decentralised local energy systems offer greater opportunity to increase the usage of low-carbon energy sources.

There are various projects that have been done to create local energy systems. The following variants cover the broad range of models , though some can cut across diffferent variants.
Description
Local consumer servicesaim to improve energy outcomes for local people, such as through providing energy efficiency schemes, fuel poverty schemes, or energy awareness and advice schemes.
Description
A local generation asset is used to benefit local consumers. The projects are usually at least partly financed by the community and generate revenue for local use.
Description
Local supply models aim to provide local communities with affordable and low carbon energy through direct supply or retail models.
Local conditions greatly affect the effectiveness and viability of most distributed generation power sources. Local options for energy generation, such as high wind speeds, high solar irradiation or the possibility of firing Combined Heat and Power Units with locally available materials, are preconditions for sustainable local energy systems. Financially viable business cases may depend on support schemes or incentives, such as Feed-in-Tariffs.
Stakeholder Mapping
Stakeholder Map of a Local Energy System (BABLE, 2021)
Government Initiatives
Various European initiatives and regulations support the implementation of local energy systems. The following figure from the Journal of Energy Efficiency shows the regulations that apply to this solution. DG in this case stands for distributed energy generations, which is the local generation of energy. As the figure shows, the regulations that strongly support the implementation of local energy systems are the EU Sustainable Energy Goals.
An example is the Directive 2009/28/EC, which includes national binding targets for EU countries. This states that by 2020, at least 20% of EU’s final energy consumption should come from regenerative energy system. Furthermore, each Member State is required to reach a 10% share of biofuels in the overall use of transport fuels by 2020.
At European level, there are also two directives referring to smart meter deployment.
Directive 2006/32/EC: regulates the use of smart meters to increase energy efficiency and better inform customers about their consumption
Directive 2009/72/EC: (Third Energy Package) encourages the implementation of smart grids, ‘in a way that encourages decentralized generation and energy efficiency’
Problems within the implementation and operation of such systems can occur due to various regulations on integrating local energy systems in the national or international grid.
Regulations that apply to Local Energy Systems (H. Lopes Ferreira et al., 2011)
Supporting Factors
Local potentials for energy gain
Already in-place distributed generation capacity
Digital monitoring and visualizations to improve user experience, consumption levels and participation
Market Potential
Local energy schemes can enhance consumer choice and competition, and electricity supply markets are quickly diversifying. For example, in the UK, the share of the electricity market owned by independent suppliers increased from 1% to 14% between 2012 and 2016 (Ofgem 2016).
Another major market factor lies in the shipping and handling of energy, which costs billions every year. These costs occur due to the construction and maintenance of massive transmission infrastructure (11.7% to 12.9% of the total energy price) due to energy losses during transportation (circa 7% of all electricity generated) and congestion charges due to peak times. In total, Forbes estimates that the costs of energy transportation represent 25% of the energy price.
Local Energy Systems do not need to transport energy as the energy is produced where it is consumed. Therefore, this 25 % can be saved using this solution. Several studies verify the cost savings of using local sustainable energy systems. For example, a study conducted by Southern California Edison in 2012 found that the utility could save $2 billion in system upgrade costs if it guided distributed generation to key locations on its grid. Also, the Long Island Power Authority determined that the development of local solar installations could meet the rising demand for electricity while saving customers nearly $84 million in avoided transmission costs in New York.
Besides the financial benefit, distributed energy generation creates a stronger, more resilient power system in the face of extreme weather, human error or terrorist attacks.

Energy Storage in Espoo's Positive Energy District
Thermal energy is stored in the ground (boreholes), in which excess thermal energy will be returned to and stored in the ground. An electric battery in Lippulaiva is used to optimize electricity usage and participating in electricity reserve markets.
Within the GrowSmarter project."Smart local thermal districts" is part of the building refurbishment in Ca l’Alier, which combines on-site electricity generation (PVs) with the local existing DHC network, reducing the consumption of fossil primary energy for heating and cooling production.
Sustainable District Cooling Solution that uses residual heat
A highly energy efficient district cooling system was installed in the densely populated city center of Tartu using the river cooled chillers. The system was made more energy efficient by Fortum, using a heat pump that reuses the residual heat from cooling system for the district heating system.
Solution for re-purposing Electric Vehicle (EV) batteries. EV taxis of the private company OU Takso in Tartu will be partially recharged based on renewable energy that is produced on-site with PV panels and stored in used EV batteries improving the yield of the batteries.
Open District Heating for Sustainable Heat Recovery
This Open District Heating aims to recover waste heat to the existing DH network by developing an innovative business model for plug and play heat pumps and contracts where the DH provider buys waste heat from local sources like data centres and supermarkets.
Switching from steam based to water based heating systems powered by biomass
Steam pipes were changed to district heating based on water as energy transmitter. The power is supplied via a biomass power plant owned by the municipality.
Greencity is the first urban district in Switzerland to meet the conditions of the 2000-watt society and represents a largely grid-independent area, relying on 100% supply from locally generated renewable energy sources and an innovative and environmentally friendly mobility concept.

According to the Energy Performance of Buildings Directive (EPBD), buildings are responsible for approximately 40% of energy consumption and 36% of CO2 emissions in the EU.
The majority of public funding for energy efficiency within the EU is proposed in the building sector. The federal funds for energy efficiency in residential buildings added up to €97 million in 2019. A Smart Home System is one possibility to improve residential energy efficiency.
Energy storage systems are used to store available energy that is not immediately needed for later use. With storage, energy can be used when needed. The goal is to create a reliable and environmentally friendly system. As the share of renewable energies increases, so does the need for storage.
The supply of energy to households, public buildings and services accounts for the majority of GHG emissions in the majority of municipalities. Municipal Energy Saving Systems represent punctual solutions to optimise energy consumption.
State-of-the-art district heating and cooling systems are paving the way for municipalities to reduce overall carbon emissions and to speed up the energy transition through the efficient distribution of heat and cold from renewable energy sources.
