Good morning ladies & gentlemen,
Switching 1 MW off during the most expensive 30 mins of every day will save your organisation €35,000
My name is Fergus Wheatley, MD of SmartPower and today I’m going to talk about how SmartPower will help save your organisation money.
My Background,
I worked in Huntstown Power Station for 5 years as the IT & Control Systems Manager, before this I spend 3 years design & project managing control systems for high voltage substations, mostly for Scottish Power and Middle East clients.
My first paper on Demand Side Management was published in 2002.
This presentation will last 4 minutes and a copy of my notes will be emailed to the delegates.
I am going to speak about three topics today
1. How SmartPower identifies and switch the most expensive electricity periods.
2. How SmartPower can tell you where electricity is used.
3. For CHP owners. I’ll tell you how we can squeeze extra revenue from your unit.
Now I’m finished my introduction, I’ll talk about how SmartPower identifies the time of day electricity costs.
Each electricity connection type has different charges associated with it. These charges change throughout the day. We calculate and aggregate these charges. Every day at about lunch time the controller downloads prices for the next 36 hours.
The controller then converts the file to calculate the current price and uses this as a variable in exactly the same way that a heating controller can use a room temperature to control a boiler.
The second topic of this talk is how SmartPower can identify how electricity is being used.
The SmartPower controller interfaces with electricity, gas, heat and water meters and passes readings to a database in the cloud.
Once there, all manner of graphs, reports and alarms can be automatically generated.
Incidentally the budget cost of installing a new sub meter is of the order of €500.
The third topic of this talk is for CHP owners. Most CHP plants run for 15 hours per day. If there is an economic use for heat then the breakeven point to run the unit is about 5.5 c/kWh. The SmartPower controller also uses a weather forecast input so it can determine whether a sufficient heat demand exists.
Using SmartPower to identify when the price is above this level allows an additional profit of 26K per MW.
Finally, in conclusion
I spoke about how the electricity price changes and how the SmartPower controller can switch non-critical load during high price periods.
Secondly, I spoke about how using the SmartPower controller can identify where and when electricity is being used.
Thirdly, I spoke about using the SP controller to generate additional revenue from CHP plants.
Thank you.
3. 3 Topics for Today
How SmartPower identifies price spikes.
How SmartPower can tell you where electricity is
being used.
For CHP owners, how to squeeze extra revenue
from your unit.
4. Different Charges for Types of Customers
Calculated daily and every lunchtime next 36 hours
of prices are downloaded to controller.
7. Same hardware as is used in US Smart Grid applications.
Software rewritten for Irish (SEM) Grid rules. (We own this)
Simple to integrate with existing control or energy management
systems.
8. Value to you
€26,000 additional profit for 1MW CHP plant.
€35,000 per annum to switch off 1MW during
the most expensive 30 minutes of every day.
Know how & when electricity is used.
Editor's Notes
SmartPower is a combination of a web-service that supplies wholesale electricity tariff information and a compatible controller that switches based on price or weather based algorithms.
This allows the customer select non-critical load to be turned off automatically when power gets expensive and turn it back on again after a configurable duration or once the electricity price reduces.SmartPower used the same underlying hardware as Enernoc in the USA. However the crucial difference is that the web-service/ databases /internal software have all been designed around Irish grid rules. We wrote the software

This screengrab from our website shows how the market price can really effect the price of electricity from ½ hour to half hour. As you can see the wholesale price of electricity changes between 5c per kWh to over 24c. It also changes from day to day. Typical within day change is of the order of 350%. Explaining the slide a little more. The red line is a typical commercial rate. The blue area is the energy price that power stations receive. The red area is payments that power stations are paid to have reserve on standby. This is worth €600 million per year in Ireland out of a total electricity market of €3 billion. Its probably obvious that business with flexible load can make savings by adjusting when power is used.

Modelling the savings, per 1 MW €35,000 is available for switching off for the most expensive 30 minutes every day. Signing up with a demand side unit will give rebates of approx. €30,000 for the ability to switch a customers load remotely. Moving from a fixed to a variable rate tariff can make sense for some customers. We can use historic data to quantity old data which can give a good insight to future action.
