Power Assure automates the reduction of data center power consumption

by

Data centre

If you’ve been following this blog in the last couple of weeks you’ll have noticed that I have profiled a couple of data centre energy management companies – well, today it is the turn of Power Assure.

The last time I talked to Power Assure was two years ago and they were still very early stage. At that time I talked to co-founder and CTO, Clemens Pfeiffer, this time I spoke with Power Assure’s President and CEO, Brad Wurtz.

The spin that Power Assure put on their energy management software is that, not only do they offer their Dynamic Power Management solution which provides realtime monitoring and analytics of power consumption across multiple sites, but their Dynamic Power Optimization application automatically reduces power consumption.

How does it do that?

Well, according to Brad, clients put an appliance in each of the data centres they are interested in optimising (Power Assure’s target customer base are large organisations with multiple data centres – government, financial services, healthcare, insurance, telco’s, etc.). The appliance uses the management network to gather data – data may come from devices (servers, PDU’s, UPS’s, chillers, etc.) directly, or more frequently, it gathers data directly from multiple existing databases (i.e. a Tivoli db, a BMS, an existing power monitoring system, and/or inventory system) and performs Data Centre analytics on those data.

Data centre

The optimisation module links into existing system management software to measures and track energy demand on a per applications basis in realtime. It then calculates the amount of compute capacity required to meet the service level agreements of that application and adds a little bit of headroom. From the compute it knows the number of servers needed, so it communicates with the load balancer (or hypervisor, depending on the data centre’s infrastructure) and adjusts the size of the server pool to meet the required demand.

Servers removed from the pool can be either power capped or put in sleep mode. As demand increases the servers can be brought fully online and the load balancer re-balanced so the enlarged pool can meet the new level of demand. This is the opposite of the smart grid demand response concept – this is supply-side management – matching your energy consumption (supply to the demand for compute resources).

A partnership with Intel means that future versions will be able to turn off and on individual components or cores to more precisely control power usage.

The software is agentless and interestingly, given the customer profile Brad outlined (pharmas, financial institutions, governments, etc.), customers log in to view and manage their power consumption data because it is SaaS delivered.

The two case studies on their site make for interesting reading and show reductions in power consumption from 56% – 68% which are not to be sneezed at.

The one client referred to in the call is NASA and Power Assure are involved in a data centre consolidation program with them. Based on the work they have done with Power Assure, Brad informed me that NASA now expects to be able to consolidate their current 75 Data Centres significantly. That’ll make a fascinating case study!

Friday Green Numbers round-up for Jan 28th 2011

by

Green Numbers

And here is a round-up of this week’s Green numbers…

  1. 50% rise in companies using software to monitor sustainability performance, says new survey

    The proportion of companies that use software to monitor their sustainability performance increased by 50 percent between 2006 and 2010, according to the results of a new international survey released today, Thursday 27 January 2011, by the Global Reporting Initiative (GRI).

    Experts from GRI say this means that guidance for people producing sustainability reports should be kept up to date with emerging trends in software use and digital reporting.

  2. Efficiency could cut world energy use over 70 per cent

    Simple changes like installing better building insulation could cut the world’s energy demands by three-quarters, according to a new study.

    Discussions about reducing greenhouse gas emissions usually concentrate on cleaner ways of generating energy: that’s because they promise that we can lower emissions without having to change our energy-hungry ways. But whereas new generation techniques take years to come on stream, efficiency can be improved today, with existing technologies and know-how.

  3. AZ Republicans and Democrats Agree, Energy Efficiency Saves Billions

    Much has been made in recent weeks of the stark political controversies that haunt Arizona politics. There, intense debates over immigration, over healthcare, over a host of issues, have led to a growing sense that Arizona?s politics have left the mainstream behind.

    But there is another Arizona, an Arizona of bipartisan unanimity and progress hidden beneath the saddening headlines of late. That hidden story of Arizona reveals a state that is leading the country down the new and much-needed road to energy efficiency, with standards that are among the most ambitious in the nation. It is a story that has been lost. But it is a story that Arizonans of all political stripes deserved to be celebrated for and a story the rest of us need to hear.

  4. Dow Moves to Make Nature Part of the Bottom Line

    Dow Chemical and the Nature Conservancy (TNC) announced a partnership on January 25 during a press conference at the Detroit Economic Club to develop tools and demonstrate models for valuing nature in business. Dow committed $10 million over the next five years to the collaboration with TNC. Jennifer Molnar, manager of TNC?s Analysis Team, called the partnership a ?breakthrough.?

    The partnership will use scientific models, maps, and analysis for biodiversity and ?ecosystem services?, a Dow press release states, and apply them to the company?s business decisions. The partnership will also ?inform Dow on setting new policies and approaches in the areas of land and water management, siting considerations, the benefits of natural resources on Dow lands and waterways, and more explicit management of biodiversity.?

  5. GM takes $7 million stake in battery startup Envia

    General Motors Co has invested $7 million in Envia Systems, a California-based start-up that has been developing more powerful and cheaper batteries for electric vehicles.

    Newark, California-based Envia has developed cathode technology for lithium-ion batteries that it says will make them both cheaper and more powerful.

    GM said Wednesday it also reached a separate licensing agreement to use the Envia cathode technology in future electric vehicles.

  6. What I Learned in Two Years of Running GridWise Alliance

    As I take my leave as president of the GridWise Alliance, I feel pride in our accomplishments and gratitude for having been involved in a period of enormous growth in the industry and organization. Alliance membership grew during my tenure from 70 to 150 members. These new members included stakeholder groups like the automotive and buildings sector that could join forces with the existing ICT, telecom, and manufacturing components and the utility and system operator member base.

    We started building relationships with consumer groups and were founding members of the Smart Grid Consumer Collaborative, bringing together regulators, consumer advocates, and industry leaders.

  7. EnerNOC Acquires M2M Communications and hundreds of megawatts of demand response capacity

    EnerNOC, Inc., a provider of energy management applications, has acquired M2M Communications, a provider of wireless technology solutions for energy management and demand response.

    According to EnerNOC, its solutions reduce real-time demand for electricity, increase energy efficiency, improve energy supply transparency in competitive markets, and mitigate emissions. Some of the energy management applications offered by EnerNOC includes DemandSMART for comprehensive demand response, EfficiencySMART for data-driven energy efficiency, SupplySMART for energy price and risk management, and CarbonSMART for enterprise carbon management.

    By acquiring M2M Communications, EnerNOC plans to expand its portfolio of automated resources, thereby augmenting third-party automated demand response.

  8. SAP reduces 2010 Greenhouse Gas Emissions despite double-digit revenue growth

    SAP today announced its preliminary report of greenhouse gas (GHG) emissions for 2010. The company?s worldwide GHG emissions for 2010 totaled 430 kilotons, a four percent decrease from the 450 kiloton level of 2009. In its third year of consecutive reductions, SAP has cut GHG emissions by 24 percent from its peak levels in 2007, putting the company well on track to achieve its target of reducing emissions to 2000 levels by 2020.

    Using its own software to measure, report and reduce its carbon footprint, SAP can attribute the emissions decrease to a variety of efforts and investments in energy and carbon efficiency projects. Contributing factors to the company?s footprint reduction also include changes in employees? commuting practices and the purchase of renewable energy.

HomeCamp 3 – hacking for smart homes, smart energy, and free beer

by

We had big plans for HomeCamp in 2010, but facts seem to have got in the way. What with Chris joining CurrentCost, and my wife and I having a second child- we didn’t have as much time to apply to the event as it deserved, or the community for that matter. Which is why I am very pleased to announce that we will be homecamping in London on December 13th from 4pm onwards.

We have some great presentations planned, from the likes of AMEE, and IBM.

That’s right. IBM in the home? Surely some mistake? Not so- Andy Piper will be coming along to tell us more about how hackers are using lightweight messaging technology from IBM in all sorts of sustainability/home hacking apps. Given I had my doubts IBM would really go after a pervasive, volume market, led by developers, I am really looking forward to this one…Dave Bartlett from IBM likes to say A Smarter Planet begins with A Smarter Building. Well, perhaps sustainability begins at home. Maybe Andy can tell us how a Smarter Planet begins with a Smarter Home.

But more importantly than great speakers is a nice venue to hang out, catch up on all things homecampy, and drink some beers. Extra special thanks to one of the stalwarts of the homecamp community- Mike Beardmore – for sorting out the venue.

So if you’re interested in home automation protocols and standards, demand response, energy management, the future of smart grids, the role of hackers and alpha geeks as leading indicators for emerging markets, and so on, then HomeCamp is the place to come – you can sign up here. We’d love to see you.

How Green Dialysis Could Save Tens of Thousands of Lives per year

by

Understanding how processes and systems act on one another is key to sustainable living. Sustainability means living without externalities – because everything we do, as individuals, organisations or companies has a cost and an environmental impact. There is a clear parallel with healthcare- which requires a deep understanding of how processes and systems act on one another. Now a research project at Geelong hospital in Victoria, Australia aims to extend healthcare models directly into the environment, and vice-versa.

Associate Professor John Agar, the Director of Renal Services at Barwon Health, said:

?Dialysis is the most water and power-hungry of any individual medical therapy.?

Each dialysis patient treatment uses more than 400 litres of water and 6 kWh of electricity. But Geelong is now using water recycling and solar power to afford the same level of care with a far lower environmental impact. Indeed the dialysis department further reduces its cost by selling excess power from its solar panels to the electricity grid. Healthcare meets smart grids. Makes sense. The idea of demand response in dialysis might strike you as somehow unethical, but what could be more ethical than effectively lowering the costs of healthcare to the broadest range of patients? Of course solar power doens’t make sense in all geographies, but it certainly does in many regions of the world. And there might be alternative, on the Eastern Sea-board, or the UK- namely wind or tidal.

Hat tip to Fresenius Healthcare, the German renal treatment company behind the initiative. Seems the German government feedin tariffs for solar power are showing real benefits in unexpected areas. Subsidise solar to subsidise healthcare… I said there were no externalities in sustainability, didn’t I?

However – its certainly not all good news for Fresenius. As a major provider of renal care in the US the company has to be horrified by the appalling record of dialysis related deaths. According to a new ProPublica story in the Atlantic.

?Every year, more than 100,000 Americans start dialysis. One in four of them will die within 12 months?a fatality rate that is one of the worst in the industrialized world.

The article is pretty horrific. The problem, sadly, is poor sanitation and an assembly line mentality to healthcare driven by the need to cut costs. Clearly we have a long long way to go before dialysis can be considered properly sustainable… and offer safer outcomes and decent quality of life to patients. Step one to improving margins and so reducing the cost-cutting mentality in dialysis care may well be reducing the costs of water and power.

It really is all connected.

Symantec’s Sustainability Story: It’s The Power Consumption, Stupid.

by

symantec commitment

I was lucky enough recently to meet Jose Iglesias, the guy spearheading Symantec’s sustainability efforts. I wrote the interview up over on Monkchips, but much of the content belongs here too. I like Symantec’s clear focus on energy. While others are broadening their sustainability story, Symantec is doubling down on managing energy more effectively, with a plan to take its expertise in reducing IT power consumption and start applying it to broader Smart Grid demand response.

Symantec?s Green IT story is very much an enterprise play and arguably a solid sustainability product strategy could help to increase visibility for some of Symantec?s enterprise tools. Thus for example ? Symantec NetBackup PureDisk for storage deduplication could be used to cut the amount of storage and power. One challenge for Symantec is identifying and serving the new buyers in energy reduction. Most of the firm?s traditional practitioner purchasers are not tasked with reducing the energy footprint of the products they manage?.

?We sell to admins, but few get compensated on energy savings?

To which I would say? not yet.

Smart Grid as Game Changer

One major opportunity for Symantec to change the account management game there is to parlay its IT experience directly into related spaces such as Smart Grid security and asset management. I knew before the briefing that Symantec is having some early success in the Smart Grid market selling, for example, cryptography. Security is a major issue overhanging smart grid and remains a key selling point.

I am not a fan of FUD though it certainly works. But let?s get real. In Europe for example we?re getting all excited about the need for smart grid standards to prevent tampering with our energy supply. Yet Russia could turn off a gas tap and we?d be screwed within weeks, no smart grid required. Whichever way you look at it ? energy reduction is going to be very big business indeed. The tail is starting to wag the dog.

So Symantec has plenty of potential upside in Green IT near term, and smart grids longer term. If you’re interested in learning more about the company’s efforts and products in energy efficiency check out the Monkchips post, which also talk to the fact the firm needs to improve its sustainability reporting in order to have a stronger voice in the sustainability conversation. I know many of you are CSR reporting nuts…

Understanding the Smart Grid – my TreeHugger interview

by

Interview

Photo credit Lee Jordan
Jaymi Heimbuch contacted me recently to ask if I’d agree to be interviewed for a TreeHugger article she was planning to write on Smart Grids. “Love to”, I said.

Jaymi sent on the questions, I replied and today she posted the interview on TreeHugger.

Here are the questions and my answers:

TH: What’s the biggest barrier with smart grids right now? Is it utilities not latching on? Is the technology too new? Is it that not enough people understand what it is?

There are multiple barriers to complete smart grid roll-outs at the moment. The biggest one, as far as I can see is money!

The smart meter roll-out alone costs in the order of $150 per household just for the device. Then there is the installation engineer on top of that. And the software to back it up. In terms of the software, remember that presently utilities take maybe one meter reading a month. When they start taking readings from smart meters they will be taking up to 2880 per 30-day month when they are taking 15 minute readings (or 720 for hourly readings). If they have 1 million customers they go from 1m meter readings a month to 720m per month (or 2,880m). That’s a massive jump in the amount of incoming data which needs to be stored, queried for billing, and held for however long.

A lot of the software to handle this is still being developed and utilities, being very conservative, don’t want to be guinea pigs. And newer technologies tend to have a price premium.

Circling back to the price for the utilities. If they have 1 million customers, they are looking at spending hundreds of millions on the smart grid roll-out (smart meters, communications infrastructure for smart meters, back-end database for data, back-office apps for using the data – customer care, billing, etc.).

One of the big deals about smart grids is that it will help us reduce our consumption – from the utilities perspective, they should invest these large sums of money so we can reduce the amount we purchase from them? You can start to see the difficulties.

TH: What’s the most apparent way a smart grid will change the average person’s daily life? What about the most important way?

You know, the best way a smart grid could change the average person’s life is ‘not a jot’ – apart from reduced utility bills.

Utilities are talking up demand response programs and how they will be able to come into your house or apartment and turn down your air conditioner (for example) at times when supply is short and demand is high. This is a top-down approach destined to piss off customers and will in no way get buy-in from a skeptical public.

Far preferable would be some kind of automated demand response, completely controlled by the consumer, so far example as a homeowner I’d set my dishwasher at 8 PM to come on at 5c per kWh or 5 AM, whichever comes first. As long as the dishes are done by 7 AM, I’m happy. Similarly with other devices. Plenty of loads in the home are movable. You don’t care when your hot water is heated, as long as it is hot when you need it hot. A well lagged (insulated) boiler would mean you could heat it when electricity is cheap, and then use it whenever.

By the way, totally counter-intuitive but cheaper electricity has a higher renewable percentage so actively selecting for cheaper electricity means you are actively selecting for electricity with a higher percentage of renewables in the mix. How does this work?

Well, electricity prices on the wholesale market are very volatile. Consumers are protected from this but electricity prices can fluctuate by orders of magnitude within a 24-hour period. Price is set by good old supply and demand. Demand fluctuates according to day of week, time of day and by season. As the price drops on the wholesale market, it becomes less attractive for more expensive generators (the ones with start-up costs for their generation – the fossil fuel burners, for example) to stay selling in so they drop out. The renewables, on the other hand, are price takers. They don’t have significant start-up costs for generation so they stay in the market no matter what price they get. So, as the price drops, more and more fossil fuel generators drop out and the percentage of renewables in the mix increases!

TH: Other than this change in demand and timing, how will the smart grid help us incorporate renewables into the grid?

Utilities are used to dealing with a situation where their generation (gas coal, oil) is steady and predictable in its output and their customers’ demand is unsteady but generally predictable (demand tomorrow = demand this day last year +1-2%, say).

For various reasons utilities are having to move to a situation where they need to incorporate more renewables into their mix. Renewables generation is not steady and is only slightly predictable (via weather forecasts, for example). Because electricity has to be used as it is generated (can’t be stored, generally), the more unstable the generation, the more unstable the grid.

How can you fix this? Well, one way would be to align the demand with the supply.

How do you do that? Well, as supply and demand shift, they affect price on the wholesale market. So, if you expose people to the real price, they will modify their behaviour to select for when price is lowest (when electricity is in lower demand (or when their is a higher percentage of renewables as I mentioned earlier)). This is demand response.

Now, however you do it, if you roll out a demand response program, you are aligning demand with supply. The more you do that, the more stable you make the grid. The more stable the grid, the more renewables that can be added to it.

TH: Many people in the US are concerned with information privacy – they want to own their energy usage data and don’t want utilities handing it over to governments and third parties. What are some of the steps both businesses and people can take to appease people’s concerns?

Let me tell you, people in the EU are far more sensitive to data privacy issues that in the US! Honestly, on this question, I’m not sure there is a good answer though.

Consider your mobile phone. It is a tracking device. As long as it is on, it knows where you are 24×7 (and tells your mobile provider). Mobile phone records have been used to both exonerate and help convict people in recent years.

Now consider people working in the call center of your mobile phone company. How much are they paid per annum? If I offer to slip one of them $2k do you think I could have access to your movements for the last 6 months? Similarly for your energy consumption data soon.

The best way to protect against this is legislation. Legislate to keep data private and have very heavy fines for the utilities (and mobile phone co.s) for breaches. This will incent them to put processes in place to track inappropriate accesses to people’s data (and disable export functions, etc.).

TH: What’s your favorite saying about the smart grid, or a quote or insight that you always remember?

I spoke to Dr Monika Sturm a couple of years back. Monika is director of Siemens Center of Competency for smart meters – their research and development facility. She told me that the output from smart meters is extremely granular. So much so, that it is possible to look at the output of smart meters and identify all the devices which make up the reading. So by looking at the output from my smart meter, it would be possible to see that I have a 2008 Philips 37″ LCD TV, and a 2006 Indesit BHZ model fridge and a …. You get the idea.

This plays back to the privacy question you asked earlier but it also offers an alternative revenue option for utilities who are looking at people reducing their consumption. It goes something like this:

I get an email from my utility saying

“Dear Tom,
we notice that you have an Indesit BHZ fridge. This is currently costing you ?25 per month to run. We have a newer, more energy efficient model on special this month for ?10 per month. It will cost you roughly ?10 per month to operate so overall you will save ?5 per month if you avail of this offer.

If you sign up, by simply replying to this email, we will have our partner install the fridge by the end of the week and we can take away your old fridge for you, for no extra charge.”

Or similar.

TH: Anything you want TH readers to be sure to know about?

The problems associated with smart meters in places like Bakersfield were entirely predictable. [Editor’s note: Bakersfield residents felt the new smart meters from Pacific Gas & Electric led to inflated energy bills. It resulted in a lawsuit.] Utilities are not used to communicating with their customers. They do so only when it is time to send the monthly bill. With the advent of smart grids, utilities will need to be in far closer communication with their customers. If people’s consumption is approaching a threshold which could push them into a higher band, send them a text/email/IM/Tweet/all of the above (or whatever the customers preferred method of communication is) to let them know. If the customer’s consumption is lowest in their block/zipcode/subdivision/whatever, let them know, etc.

Communications is not something utilities have not traditionally needed to invest any time in. However as Bakersfield has shown, it will be a vital skill for utilities in the future, especially as the markets open up and people have a choice of who to buy their electricity from.

GreenMonk talks Smart Grids with Wattpic Energia

by

While at the Smart Grids Europe conference last week, I had a talk with Dr Hugo Niesling of Wattpic Energia.

Wattpic are based in Barcelona and while their main product is photovoltaic trackers, they do a lot of research into demand response technologies and have a microgrid near Girona which has been operating successfully off-grid for 15 years making extensive use of demand response and was the only place with power when recent snow storms left 250,000 people in the region without power!

When will we have full Smart Grid deployments?

by

Despite a lot of talk and some high profile trials the day we have ubiquitous full Smart Grids is still a long way off.

I attended the Smart Grids Europe conference in Amsterdam this week.

It was a great conference, I met a ton of interesting people and had some fascinating conversations.

I can’t help feeling a little deflated though.

I’m a huge advocate of Smart Grids. I gave my first international talk about Smart Grids and demand side management (Demand Response) at the Reboot conference in Copenhagen back in early 2007. We are now a full three years later and many utility companies have yet to roll out smart meter pilot programs.

Others are rolling out smart meters more because of pending of legislative requirements than because of any desire help reduce people’s energy footprints.

In fact, after talking to more utility companies, I suspect that smart grids may not proceed beyond smart meter deployments in some regions. The recent Oracle survey of Utility CxO’s confirms this view

utilities executives put improving service reliability (45 percent) and implementing smart metering (41 percent) at the top of the list [of Smart Grid priorities]

So why the apparent passive aggressive response from the utility companies?

Well, they have to keep the lights on. To paraphrase the old saw, they do not want to ‘fix’ their grid, if it ain’t broke! And, let’s be fair, the idea of investing large sums of money to help their customers use less of their product isn’t one which sits comfortably with them. That’s understandable.

And no utility wants to have the kind of customer blowback that PG&E saw with their botched smart meter rollout in Bakersfield.

But there is a huge global imperative for Smart Grids – the Smart 2020 report said:

Smart grid technologies were the largest opportunity found in the study and could globally reduce 2.03 GtCO2e , worth ?79 billion ($124.6 billion).

How then do we square that circle?

We could legislate for them but a better approach would be to change the landscape in which the utility companies operate such that there is a business case for full smart grid deployments.

I suspect the best approach would be the introduction of a carbon tax. This is something we need to do anyway (and the mechanisms for doing so are a topic for a separate post) but if there were a tax on CO2 production, it would be in utility companies (and their customers) interests to cut back on energy consumption.

Even if there were a strong business case for smart grids, given the glacial speeds at which utility companies move, I suspect it is going to be many years before we see full smart grid implementations.
