CLEAN'S POSITION IN THE VALUE CHAIN
4
NEW solutions in a triple helix cluster
Private companies = ability to commercialize and scale new solutions Public authorities = “problem owner”, purchasing power, demand Research institutions = cutting edge knowledge, innovation, and new
ideas
CLEAN
Connect Develop Realize

Split into Energy & Environment:
- Energy infrastructure - Energy production - Energy efficiency - Energy storage
BACKGROUND – INDUSTRIAL ENERGY-PARTNERSHIP; IEP
Background to the IEP Project - Industrial Energy Partnership
• Growth Plan for Energy and Climate from October 2013.
• The Government will: “Establish a Industrial Energy Partnership regarding flexible electricity consumption in companies. The partnership should look at possibilities and limitations on how electricity consumption can be moved, and investigate how it can be easily made for companies to participate in the electricity market”.
• The Ministry of Industry, Business and Financial Affairs (at the time “Erhvervs- og Vækstministeriet”) has established the IEP project through the Danish Business Authority (Erhvervsstyrelsen).
Participants in the IEP project
Ministry of Industry, Business and Financial Affairs through the Danish Business Authority Ministry of Climate, Energy and Building, through Energinet.dk CLEAN – as the project administrator and coordinator Danish Energy Industries Federation (DI Energy) The Danish Energy Association (Dansk Energi) Case companies, incl. their electricity traders
PURPOSE: IEP-PROJECT
• To strengthen the companies competitiveness
• To test the potential for relocation of energy use in companies
• To strengthen companies and energy distributors participation in the energy market
• To prepare for the future with large quantities of RE in the energy supply
Electricity Market Operator – NordPool Spot
DEMAND RESPONSE IN THE IEP-PROJECT
• The case-companies have pointed out major electricity consuming units, where the energy consumption could be relocated within a day; be made flexible.
• The energy consumption is moved from expensive hours to cheaper hours, reducing the need for peak production.
• Within the project tests are made with both load- and fuel shift.

SYNTHETIC ELECTRICITY PRICES IN THE; CALLED SYN2020
• The project looks to the future, so that the energy prizes are geared with a factor; i.e.. larger fluctuations
• SYN2020 energy prize must represent the future energy prizes with larger parts RE
• The case-companies will in the project period receive a synthetic energy prize anno 2020 (SYN2020)
• SYN2020 energy prize is received at 2 pm and is calculated from the daily prizes from the Nordpool Spot energy stock market
• The case-companies can then organize management and energy consumption for the following 24 hours from the synthetic higher and lower energy prizes
• The project provides establishment of 15 min. individual meters and communication for measurement of the energy consumption of the chosen units.
FACTOR IS MULTIPLIED BY…
The following assumption of Demand Response for the case-company • Electric consuming unit is 1 MW or more and 400 kr. / MWh limit for DR
We use a factor 3 in the project
SYN2020 = GNS + (SPOT-GNS) * FAK (3,0)

EXAMPLES OF DEVICES/UNITS SUITABLE FOR DEMAND RESPONSE
Electric compressors for refrigerators and freezers with the possibility of thermal storage
Melting processes that can be time-shifted Electricity boilers for the production of hot liquids with the possibility of thermal
storage Electric pumps that can be switched on or off time-shifted Large electric powered machines that can be made more flexible Lighting in horticulture greenhouses that can be temporarily displaced without
disturbing plant growth Lighting, such as zoning Internal electricity production at the power plant - Fuelshift Ventilation - AC timing system; ex. Air conditioning systems that can both run
"more" and "less" than normal

We are an iron foundry and machining company about 500 employees in Holstebro
In this context, we look at the foundry that melts scrap (40,000 tons / year) to new parts such as:
Parts for the automotive industry (e.g. for Volvo, Scania, ZF)
Various types of pump circulation pumps (e.g. Grundfos)
In 2016 we consumed approx. 100,000,000 kWh, which corresponds to 23,000 Danish households' annual consumption
The production runs in 3 shifts. from Sunday evening at 22 am to Friday 14

Flexible electricity consumption and integration of renewable energy

Less El-Intensive Processes Much
LEARNINGS TO NOW
Savings between 10 and 100 DKK. each moved MWh
In 12 months, 8 GWh has been moved - equivalent to the household consumption of 2000 households
Melting of scrap - iron is a very energy-intensive
Melt in batch - each furnace
Melt independent from production - casting process
Can store the liquid iron in "thermo pot" production offset of 140 ton / day
We melt about 10 tons in 75 minutes and consumes 6,200 kWh, the liquid iron is 1500 gr.
Which processes
Melting Capacity
Melting takes place in induction furnaces (as with general induction hob at home!) The capacity is 38 ton per hour or 800 ton per. day. 94% pure scrap and remaining 1-1200 ton of pig iron
2 X 8 tonnes Medium frequency melting furnaces
1 x 12 tonnes Medium frequency melting furnaces
3 x 12 tonnes Main frequency melting furnaces
2 x 60 tonnes Holding furnaces
1 x 90 tonnes Holding furnaces
Every day at. 13:15 we will send out next day, electricity
hourly rates
September 5th we had a look from at. 8-9, where we with
the electricity supplier had agreed a maximum price we
would buy for. This means that we did not buy the amount
we would normally consume.
This will be communicated to the production, which then
organizes production thereafter.
In the beginning there was a lot of communication - verbal
about achieving the results
It did not bring the expected results
How
Every day, follow-up is
made on yesterday's
consumption patterns in
relation to the price
fluctuation of the day.
A quick feedback -
knowing whether you've
performed well or less
well - is very important
for motivation.

Our supplier of electricity
What's up for now!
There are many options
Fixed Price
Disturbance of purchased profile
Reduction of purchases at high prices
Here at the latest we have worked well to improve our profile and the possibilities there
The historical data has been processed, and it is clear how we have improved us in changing
the consumption pattern.
Future – after IEP
After CLEAN no longer delivers results of our efforts, we will
continue unchanged
Send daily prices for production
See if there are hours to respond directly to
The IEP project has contributed a lot, most of all focuses on electricity and the many
options - focusing on the point of consumption
Consumption Profile - Economy, and thereby a greener profile!
I am convinced that many companies could change their consumption profile.
In Denmark, the main part of the electricity bill is taxed.
For the community, the results would be better if politicians chose to look at the many
taxes, and with these instruments ensure industry could become competitive by consuming
electricity - when enough and the price was low. The hours when the electricity grid is not
used as much should be with reduced tax
Udbytte!
