Why we need more flexibility

A STABLE ELECTRICITY GRID

  • In every AC-grid, a stable frequency is primordial
  • National grid operators are responsible to safeguard the balance

– Enforce balanced positions via BRP role – Organise markets to procure balancing power: FCR, aFRR, mFRR

SLIDE 5

BELGIAN BALANCING POWER PRODUCTS

Primary reserves Secondary reserves Tertiary reserves

Very fast common European reserves to stabilize frequency deviations. Fast automatic reserves to restore the balance of the control area. Slower manual reserves to free up aFRR.

BUT… THE ENERGY LANDSCAPE IS CHANGING

  • Three ‘megatrends’ in the Belgian energy sector:

SLIDE 7

…WHICH PUTS THE BALANCING FRAMEWORK UNDER PRESSURE

  • More need for flexibility
  • Conventional providers: uncertain future and expensive (must-run)
slide-8
SLIDE 8

YET… A LOT OF FLEXIBILITY READY TO BE UNLOCKED

  • Small-scale flexibility under the radar
  • Entrance barriers:

– Insufficient scale – Failing to meet technical requirements – Licenses and fees – Lack of market and regulatory know-how

THE KEY: THE VIRTUAL POWER PLANT

DEFINITION (SORRY!)

  • A virtual power plant is a…

technology platform

that connects distributed energy resources to markets and services which they might otherwise not have access to. (Bloomberg New Energy Finance)

SLIDE 12

TECHNOLOGY PLATFORM: AGGREGATION BY DIGITALISATION

slide-13
SLIDE 13

CONNECTING DISTRIBUTED RESOURCES

  • Decentralised (at the DSO

level)

  • Also behind-the meter
  • Production AND consumption

(demand response)

  • A lean VPP is technology

agnostic!

ACCESS TO MARKETS AND SERVICES

Ancillary services

– Balancing markets: FCR, aFRR, mFRR – Black-start

Local network support

– Voltage regulation – Congestion management

Optimal scheduling

– Optimising production / consumption schedules based on prices

Spot markets

– Trading in day-ahead, intraday, and imbalance markets

EXAMPLE: FCR IN BELGIUM

  • 2 MW – 2 MWh battery
  • The site:

– Factory – Local wind production

  • Applications:

– FCR – Self consumption wind – Imbalance price steering

PARTICULARITIES OF THE BELGIAN MARKET

  • Usually long term PPAs
  • Regional subsidy schemes
  • Solar PV mostly small-

scale

  • Ancillary service markets

not fully opened

  • Rules are biased towards

certain technologies

  • Tedious prequalification

process

WRAP UP

  • THE PROBLEM: due to renewables we need more flexibility
  • THE SOLUTION: we can use decentralized renewable assets to

provide that flexibility

  • THE ENABLER: the VPP clusters and automatically dispatches them

USE CASES FOR DECENTRALISED ENERGY STORAGE

  • Self consumption renewables
  • Reducing grid tariffs
  • Back up power
  • Optimal schedule based on price signals
  • Local grid support
  • Ancillary services

Local optimisation Aggregator needed!

Note: trend towards value stacking
