33Production/Generation
European Union
- Any producer should be able to build new
generation facilities, on the basis of - Authorization procedure
- Licence for building generation facilities
subject to criteria laid down by the relevant
member state (such as safety, securety, public
grounf use, energy efficiency, environmental
protection - Tendering procedure
- The construction of new generation facilities
depends on the need established by the Member
State or a competent entity - Member State implementation criteria objective,
transparent, non-discriminatory
34Production/Generation
European Union
- Tendering vs Authorization
-
- What are the impacts?
35Transportation
European Union
- Operators of electricity network have to provide
third party access (TPA) to their network -
- Transport of electricity on the high-voltage
interconnected system -
- Member States must designate an Transportation
System Operator (TSO) to handle all technical
issues with responsibility for this market
36Distribution
European Union
- Operators of electricity network have to provide
third party access (TPA) to their network - Transport of electricity on the medium-voltage
and low voltage distribution system -
- Prices may be regulated
- Requirement to sell electricity to all private
consumers to the same price
37Access to the network 3 options
European Union
- Negotiated third-party access
- Electricity producers, suppliers and costumers
negotiate on access to the network, setting
transport prices and other conditions - Regulated third-party access
- Price for the use of transportation and
distribution systems is based on published prices - Single buyer option
- Legal entity responsible for the unified
management of the transportation system and/or
for centralized electricity purchasing and selling
38Unbundling and transparency of the accounts
European Union
- Entities having activities in different sectors
(generation, transportation, distribution) must
keep separate accounts for each of their
activities - Prohibiting cross-subsidization!

electricity directive but has an additional two
years in which to implement the legislation. 3
The small Luxembourg transmission network (eg,
only 91 km for Cegedel) is considered part of the
distribution network since it simply links RWE
and Electrabel to the distribution network in
Luxembourg. 4 Legal separation from generation
and retailing activities, but only accounting
separation from transmission/distribution
activities. 5 Business separation is due to be
introduced in August 2001. There will be a
requirement for public electricity suppliers
(PESs) to separate legal entities, for example in

68Energy policy
Germany
- The most recent energy program for the Federal
Republic of Germany, entitled "Energy Policy for
the United Germany," dated back to the year 1991. - The 1935 Energy Industry Act (last amended in
1977), updated in 1998, provided for an immediate
and full market opening without transitional
arrangements or strandedinvestment provisions - It incorporated the EU Council Directive
concerning Common Rules for the Internal Market
in Electricity into German law. - For the gas sector, there was no express legal
provision for negotiated network access in the
Energy Industry Act comparable to that in the
electricity sector.
69Energy Policy
Germany
- The eastern German electricity market was
exempted from the liberalization measures by the
so-called "lignite protection clause." - There were no associations agreements to regulate
negotiated network access for electricity and
gas an initial version was available only for
the electricity sector. - The 1991 Act on Feeding Electricity from
Renewable Energies into the Public Grid which
sought to romote the production of electricity
from renewable energy sources had to be adapted
to the liberalized electricity market so that
operators would again have planning security. - EU approval for the current (1998) coal aids was
lacking.
70Energy Policy
Germany
- Full account had not been taken of the 1997 coal
compromise in the federal budget. - The results of energy research were not being
translated into practice to an adequate extent. - The energy statistics had not been prepared to
take account of the liberalization of the energy
market nor were they capable to reflecting in a
sufficiently reliable manner important
energy-policy areas such as co-generation and
renewable energies. - Adequate measures had not been taken to achieve
the former government's climate protection goals
namely, a 25 reduction of CO2 in the period 1990
to 2005.
71The focus of energy policy 1998 to 2002
Germany
- Ending the use of nuclear energy
- On June 11, 2001, the federal government and the
operators of nuclear power plants signed the
agreement that serves as a basis for the orderly
termination of the use of nuclear power in
Germany. - reactor safety research and supervision by the
nuclear energy authorities will continue to
contribute in this area.
72The focus of energy policy 1998 to 2002
Germany
- Renewable energies
- EU directive on the promotion of electricity from
renewable energies in the internal market for
electricity. For Germany, a doubling to 12.5 by
the year 2010 is aimed, and for the EU as a whole
to 22. - The law on renewable sources on energy
(Erneuerbare Energien Gesetz, EEG) requires grid
operators to purchase electricity from renewable
sources at fixed prices. Covering, wind,
geothermal, photovoltaics, small hydro (below 5
MW), biomass and certain forms of waste
73The focus of energy policy 1998 to 2002
Germany
- Cogeneration or combined heat and power
generation (CHP)Overall share of CHP is 6 but
some municipal utilities have shares above 50-80
of CHP. - To protect the production of CHP plantsfrom the
effects of the liberalization (decreasing market
prices), the CHP protection law
(KWK-Vorschaltgesetz) was adopted in March 2000.
Requires grid operators to purchase electricity
at fixed prices. - The law will remain effective until 2004,
insofar as a cogeneration development law does
not become effective before that date.
74The focus of energy policy 1998 to 2002
Germany
- Climate protection
- In October 2000 the German government adopted a
climate protection program to achieve the
national target of a 25 lowering of CO2
emissions by 2005 from 1990 levels. - On November 9, 2000 German industry and the
federal government concluded a voluntary
commitment agreement for climate protection. By
2005, CO2 emissions are to be lowered by 28 and
by 2012 the greenhouse gases named in the Kyoto
Protocol are to be lowered by 35 (each relative
to 1990 levels). - With the eco tax, the German government has
provided an incentive for the sparing use of
energy and relieved labor as a factor of
production.

86Negotiated Third Party Access
Germany
- Associations Agreement Electricity
- Verbändevereinbarung
- Verbändevereinbarung I (1998) replaced by
- Verbändeverinbarung II (2000) replaced by
- Verbändevereinbarung II plus (Dec. 2001)
- Electricity industry association (VDEW),
- Association of the energy and power industry
(VIK), i.e. the industrial autoproducers and the
big final industrial electricity consumers - Federal industry association (BDI)
- Association of electricity network operator (VDN)
- Study group of regional energy suppliers (ARE)
- Association of public/municipal enterprises (VKU)
87Verbändevereinbarung I
Germany
- In the first Verbändevereinbarung, valid
until the end of 1999, transmission tariffs
were transaction based, i.e. both producer
and consumer had to be known for each
individual transaction. The tariff was a
combination of postage stamps for different
voltage levels, and entailed a distance-related
component if more than 100 km of the highest
voltage level were used. - This made the transmission tariff a hindrance
for free trade.
88Verbändevereinbarung II
Germany
- The second Verbändevereinbarung replaces the
transaction model with a point of connection
model, without distant component. It started
on January 1, 2000, and was valid for two
years. It should facilitate market
operation, as the link between producers
and consumers for each contract is no
longer needed. A consumer can switch
producers, without changing his connection
contract. This will also enable working with a
power exchange, like the EEX or European Energy
Exchange, in Frankfurt, or the LPX in Leipzig.
89Verbändevereinbarung II
Germany
- Germany is divided in eight control areas,
defined by the eight Verbund companies. The areas
controlled by VEAG, PreussenElektra, VEW
Energie, HEW and BEWAG form the newly
defined trade zone North (the light areas
in figure III.1), whereas the areas
controlled by EnBW, RWE Energie and Bayernwerk
form the trade zone South. Within one control
area, each trader, producer, consumer or other
market player has the right to build a balance
area, where his production and consumption are
added to obtain the net balance.
90Verbändevereinbarung II
Germany
- In addition, in case of transactions between a
northern and a southern zone within Germany,
which are defined in the agreement, as well as in
case of international transactions an additional
tariff of around 0,125 respectively 0,0625
kW/h has to be paid, to cover additional costs
caused by cross-zone and cross-border flows of
electricity. However, the tariff is not raised,
if it is shown that a cross-zone or cross-border
transaction does not cause corresponding physical
flows due to balancing against another flow in
the opposite direction. - But was not used!
91Verbändevereinbarung II plus
Germany
- Dec. 2001, effective January 2002
- Based on the Verbändevereinbarung II, with
- Some simplifications (especially for final
users) - all-inclusive contractThe electricity supplier
is entitled to conclude a use-of-system contract
with the system operator on a real-time basis. In
this case, a use-of-system contract need not be
closed between the system operator and the
individual customer. - The two zone concept was abolished
92Verbändevereinbarung II plus
Germany
- Pricing principles used to determine
use-of-system charges - Use-of-system charges shall be determined on the
basis of calculated costs, treating the networks
and the transformation separately. - The basis for determining use-of-system charges
is a transaction-independent point model. All
system users contribute to the system costs
through an annual use-of-system charge
93Verbändevereinbarung II plus
Germany
- Comparison Market Scheme
- In order to obtain information about structurally
comparable system operators, the three structural
features are used for a first sorting at
different voltage levels.

115Implementation of the Electricity Directive in
France
France
- The Electricity Directive was to be applicable in
France as of February 19, 1999. France and
Luxemburg were the last EU countries to transpose
the Electricity Directive. In France, the
Electricity Directive was transposed by the Law
of February 10, 2000 concerning the modernization
and development of the public electricity service
(the Law of Modernization). One year behind
the EU Directive deadline!
116Implementation of the Electricity Directive in
France
France
- Given the traditional principles in force in
France, it is not surprising that public service
obligations are at the heart of the Law of
Modernization. The Law of Modernization defines
three missions for the public electricity
service - balanced development of supply
- operation and development of transportation and
distribution networks and - supply to non-eligible customers and back-up
supplies.
117Implementation of the Electricity Directive in
France
France
- Charges resulting from these obligations will be
totally compensated through a public service fund
and an equalization fund, to which all producers,
distributors and eligible customers importing
their supply or purchasing electricity in the EU
territory and some autoproducers will contribute.
EDF will be the main beneficiary of these funds. - It appears from the Law of Modernization that the
trend in France is clearly to keep implementation
of the Electricity Directive to a minimum, which
means that the market opened to competition will
not go beyond what is required by the Electricity
Directive.
118EDFs competitors on the French market are
France
- French multi-utilities services providers, which
own or operate decentralized electricity
generators - Elyo (a Suez subsidiary), and
- Dalkia (a Vivendi Environnement subsidiary),
which, however, entered into an alliance with EDF
in the energy services sector in June 2000. - Medium-sized French public energy producers
which are currently in the process of being
privatized - Société Nationale dElectricité Thermique (SNET),
which owns five power generators using coal
(total generation capacity of 2,600 MW). In
December 2000, Endesa purchased a 30 stake with
the option to increase its shareholding up to 51.
119EDFs competitors on the French market are
France
- Compagnie Nationale du Rhône (CNR), which owns 18
dams on the Rhône river (total generation
capacity of 3,000 MW). In 2000, a joint venture
was formed between CNR (51) and Electrabel (49)
to sell electricity produced by CNR and
Electrabel to French eligible customers. - Société Hydroélectrique du Midi (SHEM), which
owns hydraulic power stations (total generation
capacity of 800 MW), is a subsidiary of the
National Railroad Company (SNCF). SNCF is
currently trying to find an equity or a marketing
partner. - Foreign electricity producers/traders supplying
electricity to French eligible customers from
other countries through export/import (e.g., RWE,
E.ON, Electrabel, Endesa, etc.).
120Generation
France
- Authorization procedure
- Generation installations may be operated by any
person duly authorized by the French Ministry of
Energy. Existing generation installations, duly
and properly established before the publication
of the Law of Modernization, are deemed
authorized. - New generators are subject to a declaration to,
or an authorization from, the French Ministry of
Energy - New generation installations with an installed
power on one site of less than 4.5 MW are subject
to a prior declaration to the Ministry of Energy. - New generation installations with an installed
power on one site of more than 4.5 MW are subject
to an authorization by the Ministry of Energy. - An authorization is also required for any
pre-existing installationwhich increases its
generation capacity by more than 10 or which
changes its primary energy source.
121Access to the electricity network
France
- Independent producers and suppliers will be able
to use EDFs transportation network, for which
they will have to pay a fee to EDF. EDF is in
fact the sole administrator of the public
electricity transport network through Réseau de
Transport délectricité (RTE). - RTE must ensure transparent and
non-discriminatory access to the network. - RTE plays an important part in ensuring that
supply matches demand
122Access to the electricity network
France
- Distribution
- The current organization remains unchanged at the
distribution level. EDF acting as a distribution
network manager, and the nonnationalized
distributors will continue to be the sole
authorized distributors.
123Price for transportation and distribution
France
- Tariffs for transportation/distribution are
uniform for all network users. The general
principles applicable to the prices for
electricity transportation and distribution were
specified in the Decree of April 26, 2001.
According to such decree, the prices must be
calculated on the - basis of all costs incurred by the network
managers. - On May 31, 2001, the CRE submitted to the
Ministry of Energy ist proposal for a definitive
list of prices. The CRE proposed a post stamp
tariff independent of the distance between the
producer/supplier and the customer, which would
be based on the electricity flows voltage,
duration and period of use.
124Unbundling
France
- In order to avoid any discrimination,
cross-subsidization or distortion of competition,
EDF, Compagnie Nationale du Rhône and the
nonnationalized distributors must keep separate
accounts for generation, transportation and
distribution activities. Similarly, companies in
the electricity sector that also have activities
outside this sector must keep separate accounts.

and to purchase all their supplies out of the
Pool to meet the demand of their customers.
132The Electricity Pool
UK
- Pricing
- NGC, on behalf of the Pool, provided an estimate
of national demand - required generators each day to provide offers
specifying the price at which they were prepared
to sell their electricity - ranked the offers in ascending order to meet its
estimated demand - and determined the Pool price at the highest
accepted offer price (i.e. System Marginal
Price).
133The Electricity Pool
UK
- Pricing
- Plus a capacity payment intended to reward
capacity availability in the and also to provide
longer-term investment signals and incentives,
was then calculated and added to the price, - depending on the amount and mix of generation
capacity declared available relative to forecast
demand. - As SO, NGC despatched plant to balance demand,
taking account of any constraints on the system. - In general, the role of demand in the Pool was
very limited since a centralised forecast of
demand was used for scheduling purposes. - However, up to 30 of the largest consumers bid
into the Pool in competition to generators (they
were known as demand-side bidders).

136Problems
UK
- Price setting was complex
- capacity payments were not working as intended,
- bids and Pool prices had not reflected costs.
- National Power PowerGen
- Approx. 40 market share, mainly coal plants
- Typical middle last, determing the SMP for a lot
of days - 1994 OFGEM
- both have to sell capacities of 6 GE
- Price cap 2.55 p/kWh
- Market power and strategic tendering
13712 month moving average Pool prices
UK
Pool prices remained around 25/MWh throughout
the period of its operation. These prices were
well above new entry cost levels, which most
commentators estimated to be in the range of
17-20/MWh at a 90 load factor.

- Introducing a new market structure (New
Electricity Trading arrangements NETA) - Similar to the Scandinavian model
140NETA New Electricity Trading Arrangements
UK
- Trading arrangements are based on bilateral
trading between generators, suppliers, traders
and customers. - They operate as far as possible like other
commodity markets whilst, at the same time,
making provision for the electricity system to be
kept in physical balance at all times to maintain
security and quality of supplies. - They include forward and futures markets, which
are evolving in response to the requirement of
participants, that allow contracts for
electricity to be struck up to several years
ahead
141NETA New Electricity Trading Arrangements
UK
- short-term power exchanges, also evolving in
response to the requirements of participants,
which give participants the opportunity to fine
tune their contract positions a Balancing
Mechanism, which opens at Gate Closure10 (3 and a
half hours before real time, since 2 July 2002
only 1 hour), in which the NGC, as SO, accepts
offers of and bids for electricity to enable it
to balance the transmission system (NGC may also
contract ahead for balancing services) - and a settlement process for charging
participants whose contracted positions do not
match their metered volumes of electricity, for
the settlement of accepted Balancing Mechanism
offers and bids, and for recovering the SOs
costs of balancing the system.

148Balancing agreement
UK
- NGC operates a balancing mechanism to achieve
production and demand balancing on a balanced on
a second-by-second basis. - About 2 per cent of electricity demand is bought
and sold by NGC in this mechanism.
149Balancing agreement
UK
- The Balancing and Settlement rules were
incorporated into the Balancing and Settlement
Code (BSC). - The BSC ascribes a number of administrative
functions to a company called the BSC Co. The
role of the BSC Co is fulfilled by ELEXON, and
ELEXON has no functions other than those ascribed
to it under the BSC. In particular, it is
responsible for contracting with service
providers (known as BSC Agents) who provide and
operate the computer and other central systems
needed for settlement under the BSC.
150The balancing Mechanism
UK
- Bids and offers can be submitted to the Balancing
Mechanism by BSC Parties (Balancing and
Settlement Code),1 although they are not
obliged to do so. A bid or offer specifies the
price that the BSC Party wishes to be paid (or is
willing to pay) to move away from their FPN and
the volume by which they are prepared to move. - Bids and offers apply to individual half-hour
settlement periods so BSC Parties can vary the
bids and offers they submit (price and volume)
across the course of a day as well as between
days. 1 This, therefore, includes for example
generators, suppliers and customers.
