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.

City Context

What supporting factors and characteristics of a city is this Solution fit for? What factors would ease implementation?

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.

Government Initiatives

What efforts and policies are local/national public administrations undertaking to help further and support this Solution?

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

  1. Local potentials for energy gain
  2. Already in-place distributed generation capacity
  3. Digital monitoring and visualizations to improve user experience, consumption levels and participation

Market Potential

How big is the potential market for this Solution? Are there EU goals supporting the implementation? How has the market developed over time and more recently?

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.

Legal Requirements

Relevant legal directives at the EU and national levels.
  • Directive 96/92/EC on the common rules for the internal electricity market
  • Directive 2003/54/EC, enabling new electricity suppliers to enter Member States’ markets and allowing customers to choose their electricity supplier
  • Regulation EU 2016/631 establishes a network code on requirements for grid connection of generators
  • Regulation 2016/1388 establishes a Network Code on Demand Connection
  • Regulation 2013/543 creates disclosure obligations that apply to data relating to the generation, transportation and consumption of electricity

The creation of this solution has been supported by EU funding
