NEW CHALLENGES IN FRONT OF ELECTRICITY GRID

Separation of activities vertically

Energy markets liberalization

New requirements for quality of services

Goals 20/20/20

•Renewable energy resources

•Energy efficiency

•Reduce CO2 emissions

Distributed generation

Market liberalization

Innovations and competitiveness

Low prices and efficiency

Availability of energy resources

Reliability and quality

New powers

Nature conservation Climate changes Pollution

4

INTEGRATION OF WIND POWERS

Turning wind into basic power

Reducing dependence on imported resources

Hedge against future higher costs for CO2

Grid parity – when prices will not be different

Germany’s example in “pacifying” the wind

5

RES IN BUILDINGS AND EQUIPMENTS

Two-way electrometers and possibility for sale

Increasing energy efficiency class

Stimulating direct use of RES

Reducing transmission at the expense of local use of energy (micro grids)

Initial investment for further cost reduction – possibility for ESCO schemes

Preferential rates or single grant?

6

ELECTRIC POWER AND TRANSPORT

Tool for storage green energy and provide reserve

Using night-rate energy

Reducing dependence on imported resources

Reducing emissions from transport

Successful conversion of company cars

Examples: Berlin, Paris, Rome…

SMART GRID RISKS

Supply

Regulation and standardization

Lack of “Smart grid” frameContradictions of pilot projectsNo clear results after investmentLack of knowledge in clients and personnel

Others

Necessary ICT support for functionalities ICT network reliability Protection of information

No legal frame Cost recognition - return Lack of unified solutions and expensive interface of available systems

Risks in suppliesThree parties in process – supplier, consumer and producer

ICT

SMART GRID GIVES NEW POSSIBILITIES

RES and E-vehicles

Consumption audit

Clients

Distribution

АММ , information portal, smart home

Tariffs New tariff structure and logic (preliminary payment and others)

Trade analysis of clients’ behaviour, consulting

Integration and optimization of use

Virtual Plants RES centralized management and optimization

Monitoring of the gridReducing disconnections Consumption control – ability of networkBetter “fill” the network

STEPS FOR IMPLEMENTING SUCCESSFUL PRACTICES

Selecting possibilities for new pilot projects

Solving the most pressing problems

Investments in innovations and technologies

Support from Regulatory Commission for covering the necessary

investments expenditures

Communication with clients for advantages of smart grid

Micro-grid development
