1

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

2

TRIPPLE BALANCE IN EUROPEAN ENERGETICS

Environment

Market liberalization

Innovations and
competitiveness

Low prices and
efficiency

Availability of energy
resources

Reliability and quality

New powers

Nature conservation

Climate changes

Pollution

3

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

4

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?

5

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


frame


Contradictions of pilot projects


No clear results after investment


Lack 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 supplies


Three 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 grid


Reducing disconnections



Consumption control


ability of network


Better “fill” the network

Market

Regulation

10

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
