11:15 - 12:45 Forecasting: Maximizing grid deliverability and leading your business processes to profitability
Resource Assessment  

Room: Tramuntana
Session description

The growth of wind energy is increasingly impacting upon and limited by the grid infrastructure of many countries. Accurate short-term forecasting of wind power can help to maintain the growth of the sector. System operators are able to avoid many balancing issues if accurate production forecasts are available. Deviation charges of wind farm owners could be greatly reduced using new techniques. Accurate forecasts can also bring significant benefits when planning turbine maintenance, especially offshore.

Learning objectives

Delegates will learn about topics including:

  • Economic impact of forecast accuracy
  • Making wind a firm resource: the role of forecasting
  • Using forecasting models to schedule maintenance activities
  • Dealing with the real world: best practices for including extreme conditions into the forecast models
  • Forecasting challenges for 2014-2020, quick-to-market tools and R&D
Lead Session Chair:

Presenter's biography

Biographies are supplied directly by presenters at EWEA 2014 and are published here unedited

Javier Ruiz has been working in the renewable energy sector for more than 10 years. Electrical Engineer (MsC) by the ICAI and Executive MBA by IE Business School he holds an extensive experience in wind power grid integration in diverse markets throughout the world. He was a member of CIGRÉ experts working group "Integration of Large Scale Wind Power with HVDC" and led Acciona WW Grid Interconnection Dep. His current responsibilities include the management of Acciona WW Forecasting Dep.; which provides different time-scope forecast for more than 8.200 MW at 312 sites in 5 continents.


In 1954 the first nuclear power plant started to produce energy, being shortly followed by other plants throughout the world. The particularities of this new source posed a challenge on the existing electric systems which at the time were mainly composed by coal and hydro power stations. As a result, new operation procedures and standards were needed; helping shape TSOs and Power Producer roles as we understand them today.

In a similar fashion, the increase of Wind Power share for the last decade has discovered new needs. In the novel developing context, forecasting stands a central role to enable wind be considered as a firm grid resource similar to traditional power sources.
This presentation will review forecast uses from this facilitating perspective.

The business processes of a power producer will be reviewed; focusing on the different time scopes present (annual, weekly, day-ahead and intra-day).

Finally, Acciona use of forecasting will be explained; detailing the forecasting development project that has been carried during the last years and exposing the attained benefits.
