The Energy Collective


This coming Wednesday, Nov 5th, sees the second installment in the Energy Collective’s Fall Webinar Series!

Up next:
Wind and Solar Come of Age: Making Renewables Full Partners in Our Energy Future - Wednesday, November 5 @ 1 PM Eastern / 10 AM Pacific, Featuring Scott Sklar of The Stella Group and Tom Raftery of GreenMonk (that’s me!).

Scale, advances in technology, and the rising cost of fossil fuels mean wind turbines and solar panels are no longer novelties. But getting the most out of solar and wind involves more than new installations. In this Webinar, we’ll examine the challenges and opportunities associated with integrating peak-load, distributed power sources in our base-load-expectant society with an electrical infrastructure built for centralized generation. More info here.

And, don’t forget the final Webinar in the Series:
Decarbonization and Nuclear Power? - Thursday, November 13th @ 11 a.m. Eastern/8 a.m. Pacific, Featuring Duke Energy CEO Jim Rogers, Dan Yurman of Fuel Cycle Week and Ashton Poole of Morgan Stanley’s Global Power and Utility Group

This controversial energy source appears to promise massive benefits, but also presents some serious obstacles. Our panelists will explore the possibility of a nuclear future in America, discussing the costs of adding new nuclear plants, the potential impact of carbon pricing, and whether NIMBY politics and regulatory barriers can be overcome.

Google and GE joining forces on clean energy

In the above video Eric Schmidt, Chairman and CEO, Google interviews Jeffrey Immelt, Chairman and CEO, GE.

The reason Google and GE were talking? Google and GE jointly announced the other day that they are coming together “to help develop tomorrow’s power generation, transmission and distribution — known as the “smart grid” — and its interface with next generation electric transportation”.

From the release:

The existing U.S. infrastructure has not kept pace with the digital economy and the hundreds of technology opportunities that are ready for market. In fact, the way we generate and distribute electricity today is essentially the same as when Thomas Edison built the first power plant well over one hundred years ago. Americans should have the choice to drive more fuel efficient cars – or even electric cars - and manage their home energy use to reduce costs, and buy power from cleaner sources, or even generate their own power for sale to the grid.

We all receive an electricity bill once a month that encourages little except prompt payment. What if, instead, we had access to real-time information about home energy use? What if our flat screen TVs, electronic equipment, lights and appliances were programmed to automatically adjust to save money and cut energy use? What if we could push a button and switch the source of our homes’ electricity from fossil fuels to renewable energy? What if the car sitting in our garage ran on electricity – the equivalent of $1 per gallon gasoline – and was programmed to charge at night when electricity is cheapest?

This is spectacular news! GE are the largest player in the power industry in the US. Their product line covers every aspect of power generation, transmission, distribution and consumption. And GE have an enviable record in renewables. They are the largest manufacturer of wind turbines globally having purchased Enron’s wind business out of bankruptcy for $300m and turned that into an asset generating between $7-$8bn in 2008!

Google get Demand Response. Coming from an Internet background as they do, they know all about the read/write web, p2p and publish and subscribe mechanisms - these are going to be the cornerstone of Electricity 2.0 as espoused by Eric Schmidt and Google in their release, and by me as I write about them regularly on this blog!

In fact, I am giving a talk at the Web 2.0 Expo in Berlin on Oct 23rd entitled “Electricity 2.0 - Using The Lessons Of the Web To Improve Our Energy Networks” - this builds on the Keynote I gave there last year on using demand response to reduce our carbon footprint.

Why don’t we already have a real time market for electricity?

Supply and Demand

If Demand Response is such a good idea and will help get more renewables onto the grid, why isn’t it being embraced by the grid management companies?

Most grid management companies have been in business for decades managing a grid in which the supply is manageable and the demand is variable but reasonably predictable - typically daily demand is “this day last year +2.5%”!

Now grid management companies are faced with a situation where an increasing percentage of their supply is coming from variable sources (i.e. wind) - if the wind blows more than anticipated, too much electricity is generated and if it blows less than anticipated, the converse is true. This totally messes up their planning and consequently grid management companies hate wind, and think of it as unpredictable, negative demand!

Instead of having such a negative attitude to renewables and shutting them down in favour of fossil fuels they should be asking how can we facilitate the greater penetration of clean renewable energy sources onto the grid.

In the coming years, the demand for electricity will increase significantly as transportation goes more electric (electric and plug-in electric cars, bikes, trucks, etc.) and as heating moves more to electricity. This will add demand to the grid system but this increased demand is eminently movable - for the most part you don’t care if your car re-charges at 7pm or 4am as long as it is re-charged when you want to leave for work at 8am. Similarly with heating, if you use storage heaters (and they will become more common) you don’t care when they suck in the heat as long as they heat the house the following day.

If you can move the demand to a time when traditionally the requirement for electricity was low, you can deliver it over the same infrastructure, thereby selling significantly more electricity without having to massively upgrade the network.

The upshot of this is that an increasing movable demand (the ability to time shift consumption) should be a strong business case for a real-time electricity market. Let demand be guided by supply (as indicated by price). With a real time market for electricity you need never shut down wind farms in favour of fossil fuels, you sell more electricity and you enable a greater penetration of renewables onto the grid. Win, win, win.

Why hasn’t this happened already? Ask your local grid management company.
