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
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”.
slide9

KINDS OF FACILITIES

  • 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.
slide10

ADMINISTRATIVE COMPETENCES

  • 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.
slide11

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.
slide12

REQUIREMENTS APPLIED TO WIND POWER FACILITIES (I)

  • 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.
slide13

REQUIREMENTS APPLIED TO WIND POWER FACILITIES (II)

  • 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.
slide14

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
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
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.
slide17

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
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.

LOWER AND UPPER PRICE LIMITS TO BE PERCEIVED BY WIND FACILITIES

Upper limit = 8.4944

Price to receive

Lower limit = 7.1275

Premium = 2.9291

Market price

If the price of the market plus the premium is below the lower limit, this limit will be received

slide21

THE REGULATED TARIFF AND THE PREMIUMS (I)

  • Parameters for establishing:
    • Regulated tariff option: IRR of 7%
    • Market option:
      • Lower and upper limits IRR of 7%, with a minimum of 5% and a maximum of 9% are the limits of the band.
slide22

THE REGULATED TARIFF AND THE PREMIUMS (II)

  • Updates:
    • Renewable: annual based on the RPI – 0.25 up to 31/12/2012 and from then RPI – 0.50.
  • Revisions. Every 4-years period:
    • Costs associated to each of the technologies.
    • Degree of participation of the special regime in the demand coverage.
    • Incidence in the technical and economic management of the system.
royal decree 1028 2007 wind facilities offshore
ROYAL DECREE 1028/2007WIND FACILITIES OFFSHORE
  • The construction or extension of the electrical systems for wind generation offshore requires:
    • The production licence given by the Ministry of Industry regulated in the Royal Decree 1955/2000.
    • The licence to set the installation on the sea as public dominion by the Ministry of Environment (Law 22/1988, of 28 of July, relative to coasts).
    • The auction result licence that grants the applicant the zone reserve, regulated in the Royal Decree 1028/2007.

      • Number of wind power producer facility owners than ere selling in the daily market: 3
      • Number of wind power producer facility owners that are selling in the daily market through units managed by other kind of agents (representative or seller agent): 212
      • Number of power producer agents without wind power facilities: 292
the wind energy price in 2006
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 Price in regulated tariff: 72.73 €/MWh

wind producers acting in the intra day market
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 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.
energy produced by technologies in 2006
ENERGY PRODUCED BY TECHNOLOGIES IN 2006 (%)

Wind power production reached 8.5% in 2006 of the demand coverage. In 2007 a 12% is expected to be reached.

slide48

DAILY WIND GENERATION IN 2006 (MWh)

On December 8th, 2006, a maximum in wind power production was achieved with an average daily energy of 159,291 MWh and an hourly energy of 8,010 MWh at 15:00 hours. This wind power production covered 23.3 % of the domestic demand

conclusions1
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.
