DISTRIBUTION NETWORK
In Bulgaria
Shares of distribution length power lines per type
• Length: 154 000 km or 1,5% of the distribution (LV, MV and HV) for each MS
network of Europe
• Number of customers: 4,9 mln or 1,8% from all
the customers in Europe
• Distributed energy: 26 TWh or 0,9% from the
distributed energy in Europe
In Europe
• Length: 10 mln km (10 times the distance from
the Earth to the Moon and back)
• Number of customers: 260 mln
• Distributed energy: 2 700 TWh
THE GREEN DEAL IS BECOMING
MORE AND MORE AMBITIOUS
• On 17th September the European Counsil proposed the GHG-emissions to be
reduced by at least 55% (ЕP – 60%)
The EU RES target(38-40%)
• This will lead to a higher levels of: The EU Energy Efficiency target
The national contribution (integrated
NECPs)
• By June 2021, the EC will review and propose amendments to relevant policy
instruments to achieve further emission reductions

THE ELECTRICITY INDUSTRY:
THE REGULATION IS NOT IN STEP WITH
THE ENERGY TRANSITION
The first three necessary changes are:
1. New design of network tariffs to ensure that the new entrants / the decentralized generation
pay a price commensurate with the network costs they cause
2. The micro-networks, local energy communities and prosumers should be subject to the same
responsibilities as other network operators
3. Rapid introduction of IMS and dynamic tariffs to provide maximum incentives for flexibility
and optimization of system costs

PERSPECTIVES TO THE DSOs
«Development of electricity transmission and
distribution infrastructure, of smart networks, of
storage facilities and interconnectors in the period
2021-2030 »
«Introducing a simplified procedure for grid connections
when installations of renewables self-consumers and
demonstration projects that use renewable energy with
an electrical capacity of 10.8 kW or less are to be
connected to the electricity distribution networks»

PERSPECTIVES TO DSOs
• As regards measures for reducing technical losses in electricity transmission and distribution via
the electricity distribution network, the network operators carry out the following activities:
Reducing technical losses in electricity transmission and distribution by means of:
− building new transformer units to reduce the length of outlets of low voltage networks and/or
redistribute power loads;
− replacing installed power transformers by new ones, with lower losses of energy in no-load
condition and short circuiting;
− thermal imaging audit of transformers, medium and low voltage units to detect problem areas with
rising temperature;
− increasing the cross-section of medium- and low-voltage conductors in cable and overhead
networks.
• Increasing the reliability of measuring the quantity of electricity that is received in or leaves the
electricity distribution grid and limiting the option for its unauthorised use through:
replacement of commercial metering devices
securing and re-locating commercial metering devices on the boundary of ownership
building SMART GRID networksNECP:
REGULATORY PRINCIPLES
EWRC is guided by the following general principles:
• In terms of energy efficiency (EE)
promoting the increase of energy efficiency in the production, transmission, distribution and final consumption of energy and natural gas
creating incentives for transmission and distribution system operators to provide system services to end customers, which enable the
implementation of measures to improve EE by introducing smart grids, taking into account the costs and benefits associated with each measure,
while ensuring system security
• In terms of demand optimization
The prices for transmission and distribution shall allow increasing the participation of end customers in improving the efficiency of the electricity
system by demand optimization
to encourage transmission and distribution system operators to offer system services for the optimization of electricity consumption, energy
management and decentralized generation within organized electricity markets and to improve efficiency in the design and operation of
networks, in particular:
− load shift from peak hours to non-peak hours by end customers, taking into account the availability of energy from renewable energy
sources, cogeneration and decentralized generation
− energy saving by optimizing the consumption from decentralized generation sources by combining the provision of energy efficient services
and participation in the balancing electricity market
− reduction of consumption through energy efficiency measures implemented by energy efficient services providers
− connection and dispatching of energy sites for MV and LV power generation
− connection of energy facilities for electricity production, located closer to the points of consumption
− providing access to the networks of energy storage facilities
