Smart electricity meter projects are being rolled out all over the globe at this stage (here’s a map of the Smart Meter projects in the US), and with the Smart Meters, come Smart Grids and Demand Response programs whereby the utilities implement peak shaving programs (and in certain cases demand stimulation) to match demand and supply curves. This will lead to a more stable grid and therefore increase the amount of variable generators (i.e. weather based renewables) it is possible to add to the grid. Great.

However, this is not nearly ambitious enough as far as I am concerned. First off, as I have said previously, cheaper electricity typically has a higher % of renewables in the generation mix. Therefore, if I am getting a smart meter, I want it to be a very smart meter. I want my meter to be going out across the grid, checking the realtime price from all utilities and dynamically sourcing the energy from the cheapest supplier at any given time. Nothing too new there, I have written about that concept previously.

Taking that idea to the next level. Imagine if utilities were mandated to publish, not only the price of electricity in realtime, but also the generation mix. I could then have a Smart Meter which would actively chose the greenest electricity for me at any time. Or the one with the best price/renewables mix.

And if we had a SuperGrid in place, then that Green electricity might be coming from Danish windfarms, Icelandic geothermal generation or North African solar farms.

Now that would be a Really Smart Meter!

UPDATE - I have been asked the relevance of the photo above - it is subtle, anyone care to guess?

Smart Grids and unlocked Smart Meters

I have been talking to a lot of Smart Meter and utility companies in the last few weeks and it has been fascinating. I have learned a huge amount about some of the challenges and opportunities involved in rolling our Smart Grids.

The first thing to say is that Smart Grids are coming. None of the utilities I have spoken to have given me feedback to indicate that they are rolling back on their Smart Grid projects - and they all have Smart Grid projects at some level, whether it is in planning, in trial or in roll out.

One of the questions I have asked and not received a satisfactory answer to yet is “What happens if I decide to change utility co.? Does my existing utility come along, take the Smart Meter off my wall and my new utility then needs to send an engineer to install their Smart Meter?” Unfortunately, so far the answer to this appears to be “Yes”!

In reality, this will probably be solved with some kind of cost or asset transfer solution.

As an electricity consumer (be that industrial or residential), ideally what I want is either an ‘unlocked’ Smart Meter, or one which is owned by the grid management company, as opposed to one which is locked into a particular utilitity.

In fact, for me the ultimate solution would be a neutral Smart Meter which can go out at all times, find the cheapest electricity at that time and pull from that utility!

GreenMonk interviews Stefan Engelhardt about SAP’s vision for Smart Grids

One of the more interesting keynote talks at the recent SAP for Utilities conference in San Antonio TX was the one given by Stefan Engelhardt, SAP’s Head of Industry Business Unit Utilities.

In his keynote he discussed decarbonisation and SAP’s vision around Smart Grids and Smart Meters. I asked him if he’d be willing to come on camera to talk about some of these topics and he very graciously agreed.

With the vast majority of the world’s utilities using SAP’s software, they have their fingers firmly on the pulse of this sector. What was pleasantly surprising to me was the amount of interest SAP is seeing from their utility client companies in Smart Grids. As Stefan himself said in the interview:

For the next couple of years we see a clear trend towards the deployment of Smart Metering technology in the Utilities industry… and that means we have to adapt the existing business processes to this new technology

It was also fascinating to hear Stefan’s predictions around how Smart Grids will be rolled out gradually by utilities. Polling of smart meters by utilities will be ramped up bit-by-bit from maybe once a day to once every 10-15 minutes and this will have huge implications for the amount of data utilities will have to manage. Previously they may have collected 1 terabyte every 10 years. With smart meters reporting energy usage every 10-15 minutes they could be collecting 1 terabyte every month, or less!

With the roll-out of Smart Grids, utility companies will be able to publish energy prices in realtime based on supply and demand. This is important because electricity is more plentiful when renewables are contributing to the mix, so cheaper electricity should also track closely with Greener electricity!.

Utilities will now be able to offer new products like critical peak pricing for peak shaving in times of electricity shortage and even demand stimulation, to encourage people to consume electricity when supply is exceeding demand. This will encourage people to shift some of their loads to times when renewables are contributing more, thereby reducing the CO2 emissions associated with that load.

The observant amongst you may have noticed that we have talked quite a bit about smart grids here on GreenMonk. That is because we believe fundamentally in what it is they are trying to achieve and how they are going about it.

And we are not alone in that!

SAP’s AMI Lighthouse Council is all about Smart Grids and hence SAP are holding their SAP for Utilities conference in San Antonio Texas in October where there will be a major focus on Smart Grids.

As well as SAP, not surprisingly the utilities are all over this space because Smart Grids will give them the ability to far better manage their energy supply and the demand, thereby reducing the number of outages. It seems that every day brings news of a new Smart Grid trial by some utility.

ComEd are looking at Smart Grids in Chicago, Manitoba Hydro is testing about 4,500 smart meters in Winnipeg, Xcel Energy has announced plans to make Boulder the first SmartGridCityTM, PEPCO has rolled out a Smart Grid trial in 1,000 homes in Washington DC, Austin Energy plans to have all its meters converted to Smart Meters by December 2008, etc. In fact, here is a Google Map of all the Smart Grid projects currently underway globally!

As well as the utilities, because this is a whole new area, there are literally hundreds of startups in this space from the likes of SynergyModule in Ireland to more established names like Echelon and Itron in the US.

Because of the involvement of these myriad players, IBM has also come on board to try to bring some standards to the table. According to this recent article in CNet,

The idea is to create a common set of communication protocols and data formats that utilities and smart-grid start-ups can adhere to.

With these technical blueprints, based on standards like TCP/IP, new technologies can be plugged into the grid on a large scale…. What’s happening now is a patchwork of smart-grid trials using differing products, an approach that prevents fast technology change.

This is great news for the rollout of Smart Grids globally. If we have a universally agreed set of standards that everyone adheres to then the creation and integration of smart grids and smart grid devices suddenly becomes far less complex.

It will still take some time before there are the devices in place, and the regulators and utilities sign-up to convert completely to Smart Grids but a heavy weight like IBM’s coming on board can only help move things along.
