Héloïse Hoyos, Senior consultant at N-SIDE, gave a presentation about how to valorize your energy flexibility during the Energy Flexibility Forum organised by Solar Plaza on June 11-12

Process
Where is my energy
flexibility ?
Two main topics to address when
speaking about Demand Response Management
Which kind energy
flexibility ?
How much from my
flexibility can I
leverage .
How can I use it
managing all my
constraints ?
What does flexible
mean ? I don’t want
to stop my process !

4. Multiple Energy flexibilitiy levers
observed in Industry
What ?

5. 5
Many flexible processes:
… with opportunities in various areas from electro-intensive to residential level

What energy
flexibility ? Which
process/asset ?
What ?

6. Extract and daily operate the energy flexibility can be
complex and multiple aspects need to be considered

Process planning is not only about electricity cost…
Minimize Energy
Bill
Minimize
Operational Cost
Minimize
Time spent
Many additional constraints need to be taken into account: Technical,
Economical and Commercial ….
Also the willingness needs to be considered (i.e. Residential flexibility)
… many other objectives need to be considered
(i.e. minimization of the time spent charging a EV)
… Finally, reactivity is a key in the design of an optimal planning
in order to make the most from the flexibility.

• Programs giving customers time-varying rates
that reflect the value and cost of electricity in
different time periods.
• Armed with this information, customers tend to
use less electricity at times when electricity
prices are high
Implicit Demand ResponseExplicit Demand Response
Two types of Demand Response (DR)
DR Programs offering complementary opportunity to flexibility
Incentive-Based Demand
Response
Price-Based
Demand Response
• Programs that pay participating customers for
reducing or increasing their loads at a specific
time defined by the program sponsor.
• These events are triggered in general by a grid
reliability problem.

10. Markets requirements for valorization Energy Flexibility
Level of Reactivity
Energy Constraints
Commitment Timing
Remuneration ?
Access
How fast I am supposed to be able to react ?
With which time granularity do I need to follow a setpoint
?
How often do I need to react/adapt my load ?
How long do I need to reduce/increase my load ?
How long in advance do I need to commit in terms of
availability ?
What level of remuneration can I expect ? For my
availability (Reservation cost) ? For my activation/energy ?
How can I have access to this flexibility product/approach
? What type of electricity contract do I need to have ?
How much can I hope ?
I have a high cost to
operate my flexibility

13. Concrete example: Pulp and Paper Industry
Mechnical
Pulp Lines • Overcapacity: 10%
• High Consumption: 30 MW
• 5 Lines of ON/OFF Process
• Ramp up/down constraints 1H
• High Supply Chain constraints
Paper
Machines
• No overcapacity
• Medium consumption: 6 MW
• No stops allowed (high cost to
start-up and production loss)
CHP
• High production of electricity: 20 MW
• Steam Storage ( 10H of steam
demand)
• Highly flexible to switch production
level of steam vs electricity
WHAT to leverage ?
Mechnical
Pulp Lines
• Min time step 1 hour
• Load Shifting opportunity
• Production planning set-up in
advance
Paper
Machines
• Load Shedding opportunity
• High cost to be covered
• # of Activations of flexibility
should remain limited
CHP
• Time step is short [1- 15 min]
• # of activations of flexibility can be
high
• Period of activation can last up to 10
