INSTALLED POWER IN THE SPECIAL REGIME IN SPAIN AND FORECAST UNTIL 2010 (MW)

Source: Renewable Energy Plan

RECENT FORECASTS FROM THE MINISTRY OF INDUSTRY, TOURISM AND COMMERCE

The forecasts of the Secretary General of Energy, aim at:

35,000 MW in 2020 and

44,000 MW in 2030.

In addition, “during the following 10-years period, the renewable energy will be able to compete without premium”.

2. Spanish regulation on power production in the special regime.

Cogeneration and waste energy.

Renewable energy:• Group b.2 Wind power.• Group b.2.1 Windmills onshore.• Group b.2.2 Windmills offshore.

Waste energy with energy value.

Installed power per unit must be < 50 MW.

KINDS OF FACILITIES

Installation licence corresponds to regional authorities.

Nevertheless, this competence is of the State Government when:• The installed power is > 50 MW.• Its location affects more than one Region.• It is located offshore.

Regulated price corresponds to the State Government:• Fix price applied to wind energy.• Premium over the market price:

Wind power onshore: Fixed by the Government.Wind power offshore: Established by auction.

ADMINISTRATIVE COMPETENCES

ACCESSING THE NETWORKS

Priority for accessing the transmission and distribution network.

Mandatory guarantee to be applied when accessing the transmission and distribution network:

• 20 €/kW for wind power facilities.

Once the wind power facility starts up, the guarantee is cancelled.

Adscription to a generation control centre, as a dispatch centre connected to the system operator:

• Producer.

• Special dispatch in the system operator.

All the facilities with capacity > 10 MW should be connected to a control centre or establish by itself a control centre.

• Information will be transmitted to the system operator and instructions to control centre will be executed in real time.

• This obligation will be a necessary condition for the perception of the tariff or the premium.

REQUIREMENTS APPLIED TO WIND POWER FACILITIES (I)

The wind facilities will have to fulfil certain response requirements when a voltage dip.

• This requirement will be a necessary condition for the perception of the tariff or the premium:

A transitory period is established until the 1st of January of 2010 without penalty, for the existing facilities before the Royal Decree is in force.

A transitory period is established for the facilities previous to 1 of January of 2008, during a maximum term of 5 years, for maintaining the continuity of supply, receiving a complementary income of 0.38 c€/kWh.

REQUIREMENTS APPLIED TO WIND POWER FACILITIES (II)

SELLING THE WIND ENERGY

The wind energy producer has two options:

• To sell the wind energy at a fix regulated tariff equal for all the hours (option a).

• To bid in the organized market, through the system of auctions managed by the market operator, to establish a bilateral contract, or a forward contract (option b).

OPTION A: TO SELL AT A REGULATED TARIFF

The wind power producer communicates the day ahead schedule to the market operator:

The auction system managed by the market operator considers this schedule as a bid at null price.

The schedule can be communicated directly or through a representative.

Producers can send bids also to the intra-day market

The wind power producer is paid by:

The market operator for the amount that corresponds to daily and intra-day market.

The system operator by the amount that corresponds to the ancillary services and deviations.

The Energy Regulatory Commission for the rest of the fix price of the tariff. This part of the retribution is paid until 2009 by the distributors.

OPTION B: TO SELL IN THE MARKET (I)

The wind power producer send the bids for the day ahead market to the market operator: The bid can be sent directly or through a representative.

Producers can also send bids to the intra-day market.

The price is paid to the wind power producer by: The market operator for the amount that corresponds to daily and intra-

day market.

The system operator by the amount that corresponds to the ancillary services and the deviations.

The Energy Regulatory Commission for the premium. This part of the retribution is paid until 2009 by the distributors.

Alternatively the power producer can sign a bilateral contract or operate through the forwards market.

OPTION B: TO SELL IN THE MARKET (II)

Negotiated price+

Premium+

Reactive energy complement-

Deviations+

Complement to help voltage dip problems(applicable to wind facilities previous to 1/1/2008 and

maximum 31/12/2013, that support voltage dip)

REQUIREMENTS THAT THE WIND PRODUCERS SHOULD COMPLY

In case the entity accessing the market on behalf of the wind producer is not a market agent, then the wind producer should be a market agent.

The entity accessing the market on behalf of the wind producer can send several bids for the set of facilities of the wind producer.

The dominant operators will only be able to act as representatives of their own facilities when their participation is greater than 50%.

The non dominant operators, will be able to act as representatives, until they reach a maximum of 5% of all the suppliers.

THE WIND ENERGY PRICE IN 2006

This participation of the wind energy in the electric market diminishes the price of the electricity due to:

The incorporation of the wind energy moves the market supply curve causing a lower price.

In addition, the wind production is greater in periods of low/medium prices, because the local winds take place in the periods of diurnal transition that in many cases does not correspond with the highest demand.

Wind price in the daily market: 48.01 €/MWh, is lower 4.96% to the arithmetic average price of the daily market (50.52 €/MWh)

WIND PRODUCERS ACTING IN THE INTRA-DAY MARKET

The wind producers are very active in the intra-day market:

As weather forecast is close to real time, the producers modify schedules to more accurate figures.

To solve the power production unavailability.

THE FORWARD CONTRACTS AND THE DAILY MARKET

The participation of the wind power producers in the daily market serves to them as a base to be able to take part in the CESUR (last resort supply), VPP auctions and the forward organized market, buying or selling the necessary amounts of energy to fulfil their compromises.

5. Conclusions.

CONCLUSIONS

From 1994 to now, wind energy production have been growing in an uninterrupted way.

The price of the market plus the premium has been attractive enough to build 12,900 MW of installed wind power.

The management of the electric system has changed to integrate many small producers whose production will increase or diminish based on the wind regime.

Most of the wind energy producers have chosen the option of bidding into the market instead of the option of the fix price.
