Conclusions
Founded 1.000 MW DRR for system services includen
demand reduction and on site security generation.

• Larger segment response
• 311 MW Desalation (Total consumtion
  interuption, long response, short notice)
• 166 MW Cement (Securty and load reduction)
• 124 MW large commercial surfaces Big stores and
  hipermarkets (Security generation thermal
  inertia)

• Half of households would accept a intelligent
  plugs that operate some of their appliances
• following
• System Operation instructions paid service or
• Chipper prices periods.

15
Conclusions
Considering load reductions ceramic and
disalation have the bigger capacity

• Load reduction capacity that could be offered un
  the short term
• Expert valuation (X axis).
• Declared by the segment representing company (Y
  axis).

Conclusiones del estudio - Resultados
Se puede dividir los sectores en tres grandes
grupos con perspectivas de gestión en sus
procesos.

• Group 1 High operability
• More immediate and less barriers.
• a) Water utility Desalation, con 311 MW.
• b) Cement, con una estimación inicial de 21 MW.
• c) Sector Bier, con 32 MW.
• e) Large commercial stores, con 67 MW

Grupo 1
Grupo 2
Grupo 3

• Group 2 Medium
• Atmospheric gases con 23 MW, Paper 55 MW, y
  frozen13 MW.
• Group 3 Difficult to operate
• Ports, Irrigation, Hotels.

Conclusions
Different solutions to gibe demand response
Almost complete load reduction, workers turns
shifting, thermal inertia management y on site
generation

Conclusiones del estudio

• Se amplia el conocimiento sobre acciones de
  gestión de demanda en los diferentes sectores.
• Desconocimiento, por parte de los consumidores,
  de la posibilidad de gestionar la demanda.
• Incapacidad de cuantificar la potencia
  gestionable y, sobre todo, los costes de dicha
  gestión.
• La utilidad de las curvas de carga.

GYMCO Large and medium consumers Issues to deal
with

• Industrial customers
• Personal high number of employees difficulties
  translation of shifts.
• Companies feel curtailment decreases quality.
• Seasonally large number of peak season which
  restricts demand management.
• Percentage of the electrical cost over the total
  cost Companies with low influence over energetic
  costs are less willing to modify their production
  in order to get a low benefit.
• High price of gas and uncertainty about its
  supply may aggravate situation in CHP.
• High number of production plants in certain
  sectors make it difficult to manage and aggregate
  in critical areas.
• Services associated with supply of essential
  services like water distribution refrain
  capability for demand management.
• Need of investment to increase demand management
  capability
• Change in mentality in order to transfer shifts
  or manufacturing against stock when planning
