Using Water Heaters to Store Excess Wind Energy

The Bonneville Power Administration (BPA) is recruiting one hundred homeowners in Washington for an experiment on how to store surplus wind energy. The BPA is testing a promising smart-grid concept that would use residential water heaters to help manage the fluctuations of wind energy generation.

The project will address two problems experienced on the grid: shortage of power during peak times and surges of power during windy periods, when the energy isn’t needed.

The BPA, working with Mason County Public Utility District Number 3, will install special devices on water heaters that will communicate with the electrical grid and tell the water heaters to turn on or off, based on grid conditions and the amount of renewable energy that’s available.

While homeowners will be able to override the control device at any time, it’s unlikely that they would even notice a change in temperature.

The water heaters in effect become energy storage devices — turning on to absorb excess power and shutting down when demand ramps up —leveling out the peaks and valleys of energy use. Benefits include:

no need for expensive and toxic battery storage
no need for fossil fuel burning power plants to fill in low wind energy gaps
water heaters provide distributed storage, avoiding point loads on grid
smart water heaters can be manufactured economically, for just a few dollars more.

Wind power is the fastest growing source of renewable energy, accounting for about 3 percent of US electric generation. About 53 million homes in the United States, or 42 percent of the total, use electric hot water heaters. Added up, they account for 13 percent to 17 percent of nationwide residential electricity use.

In the Pacific Northwest, home of the BPA, it’s estimated that there are 4.3 million water heaters that can store 2,600 megawatt-hours by allowing the storage temperature to vary by five degrees. (NB: For a detailed analysis see the Northwest Power and Conservation Council report prepared by Ken Corum.)

The Northwest Energy Coalition does a nice job detailing the background, and benefits of this approach to storing excess wind energy. Highlights of their article, Using simple smart water heaters to integrate intermittent renewables, are below.

Highlights of Using simple smart water heaters to integrate intermittent renewables

Background

Wind-generated power is clean, relatively cheap and available in large quantities. But the wind itself is quite unpredictable, so much so that for each average megawatt (aMW) of wind power we need, we must erect about 3 megawatts of turbine capacity, since actual output could be anywhere from 0 to 3 megawatts at any instant.

Suppose our region, which consumes about 21,000 average MW of electricity each year, wants to get a third of its power from wind. We’d have to build about 21,000 megawatts (MW) of turbine capacity to get 7,000 average MW of electricity. Given weather variability and the geographical spacing of wind projects, over time the actual production of those 21,000 megawatts of turbines will vary from about 1,000 MW to 15,000 MW due to weather fronts and daily warming patterns. Problematic 3,000- to 4,000-megawatt swings can occur in as little as 10-30 minutes.

To deal with large variations in wind, grid operators use some expensive tools now at their disposal, generally limited to ramping natural gas-fired combustion turbines and/or hydro generation up and down. Ramping up is fairly easy; today’s grid has ample reserve capacity on which to draw.

Ramping down is another matter. When wind generation suddenly spikes during periods of low demand (at night or during mild weather hours), the system can have less flexible generation on-line (nuclear and coal plants) that cannot be cut back to make room for the wind. The region’s inflexible “baseload” coal plants and one nuclear plant, which together provide more than a quarter of our electricity, cannot be economically ramped up and down in response to wind variability.

Previous Transformers and NW Energy Coalition’s Bright Future report have addressed wind-integration issues, noting – in particular – that the problems will lessen as we progressively eliminate coal-fueled power from the Northwest grid, as renewable projects grow and become more diverse and geographical dispersed, and as “smart grid” deployment provides a new back-up resource.

Smart grid to the rescue

In a Feb. 10, 2009, presentation to the Northwest Power and Conservation Council, Council staff member Ken Corum provided a powerful example of how one relatively simple smart grid innovation – using electric water heaters as temporary storage devices — could help the grid integrate large amounts of wind power at very low cost. We expand on Corum’s example below.

The Northwest power system serves about 4.3 million electric water heaters. If all were running at once, their loads would total more than 19,000 MW. Of course, they don’t all run at the same time. Actual demand might be just a few hundred megawatts in the middle of the night, surging to more than 5,000 MW around 8 a.m. when people take their showers. Use drops during the day, and then peaks again at about 3,500 MW around 8 p.m. as people come home and wash dishes, clothes, etc.

Now imagine that as part of the smart grid, each water heater contains a chip that can receive signals from grid operators to raise or lower the water temperature by a few degrees. As wind generation picks up, the grid operator slightly raises the temperature set points on millions of water heater thermostats, thus “storing” the wind power for later use. Should the wind suddenly drop, the operator lowers the temperature points, causing many water heater elements to click off for a time.

Most people won’t even notice the small temperature changes. But spread over millions of water heaters, those few degrees of difference are enough to avoid ramping fossil-fuel and hydro generation up and down, thus improving system-wide fuel efficiency and leaving more water in the river for migrating salmon.

Once the infrastructure — smart meters that can communicate with both the utility and home appliances — is in place, manufacturers could start installing computer chips, adding perhaps $5-10 to the cost of a water heater, Given the system savings the water heater controls would generate, utilities could afford to cover the additional cost, and/or offer customers a rate discount or other incentive in exchange for limited control of their water heaters.

Currently, for example, Idaho Power pays residential customers $7 per month to participate in its A/C Cool Credit Program, which slightly backs down air conditioning power during peak demand periods.

Water heaters are a great choice for smart grid applications because of their relatively short life spans. Over about 12 years, the current stock could be totally replaced with smart water heaters.

Shifting peaks – and keeping the lights on

Aside from facilitating the integration of thousands of megawatts of wind power, controllable water heaters (and other appliances and equipment that draw electricity 24/7) provide two other benefits:

1. Reliability. Major power lines and generating plants occasionally suffer sudden outages due to fires, ice, wind or equipment failure. Turning down a few million water heaters could quickly shave demand enough to cover the power loss and avoid a major blackout. In fact, the chips discussed above can be made to automatically and instantaneously detect frequency changes in the electricity they use without any operator intervention. The chip reacts to a sudden change from the standard 60 cycles per second by instantly turning the heater on or off to keep the grid stable.

2. Money. Utilities spend a lot of money following the daily peaks and valleys of human activity. Thirty to 40% of their generation capacity sits idle for much of each 24-hour day. Another 5-10% come on only during very extreme weather — the hottest or coldest days. But utilities must cover the capital and maintenance costs of all these resources, no matter how little used.

Controllable water heaters would rarely go on during system peaks and could help utilities respond to system emergencies … at huge cost savings. Utilities would be able to spread demand more evenly throughout the day, increasing power line and substation efficiency and avoiding the costs of some mostly idle generation resources. These actions could lower bills substantially and/or provide savings to fund additional smart grid investment.

And that’s just one example

Though this article has focused on electric water heaters, similar controls can be installed in freezers, air conditioners and electric furnaces. Electric and hybrid-electric vehicles are other examples. Their charging rates can be altered while the vehicles are plugged into the grid. The opportunities are only starting to reveal themselves.

Allowing grid operators access to our appliance controls raises issues of cybersecurity, privacy and the potential for short-circuiting due process (e.g., automatic shutoff for non-payment of bills). Those issues must be adequately addressed. But the smart grid can help move the Northwest quickly and affordably to a bright energy future.

Creating Leaders Great at Performing in Uncertainty without a Clue as to Why

Posted on 14 July 2010 | by Belina | 3 Comments

There is an interesting phenomena going on in some of the major business schools in Europe. In some – you are not allowed to mention environmental factors as a major catalyst for new business models/thinking. It is “understood” that as a lecturer, you inspire the students with fresh thinking but only so far. Go further, and people just roll their eyes and pigeon-hole you as a treehugger.

Here are three quotes from top business leaders:

“The era of ‘abundance’ is over. The future will see our natural resources, from oil to food, having some level of restriction placed on them.” – Andy Bond, CEO, Asda (May 2009)

“We must rapidly wean ourselves off our dependence on coal and fossil fuels.” – Richard Branson, announcing investment of all profits from Virgin transport business, estimated at $3 billion over 10 years, to be invested in fighting global warming. (21 September 2006)

“Sustainability is here to stay or we may not be.” – Niall Fitzgerald, UK CEO, Unilever

Now, none of these guys are particularly treehuggy. And most MBAs would give their eyeteeth to fill the shoes of these guys – and yet – in many MBA programs – coverage of sustainability issues is absent, apologetic, sidelined, or sketchy.

Let’s stop tiptoeing around the obvious. Business leaders can handle the truth. Though there is uncertainty on what the impact will be, climate change is a global issue that will impact business. Period.

In 2008 the US Director of National Intelligence (DNI) presented to Congress the DNI report National Intelligence Assessment on the National Security Implications of Global Climate Change to 2030. Here are a few excerpts:

“The United States depends on a smooth-functioning international system ensuring the flow of trade and market access to critical raw materials such as oil and gas, and security for its allies and partners. Climate change and climate change policies could affect all of these—domestic stability in a number of key states, the opening of new sea lanes and access to raw materials, and the global economy more broadly—with significant geopolitical consequences.”

“In addition, anticipated impacts to the Homeland—including possible increases in the severity of storms in the Gulf, increased demand for energy resources, disruptions in US and Arctic infrastructure, and increases in immigration from resource-scarce regions of the world—are expected to be costly. Government, business, and public efforts to develop mitigation and adaptation strategies to deal with climate change — from policies to reduce greenhouse gasses to plans to reduce exposure to climate change or capitalize on potential impacts—may affect US national security interests even more than the physical impacts of climate change itself.”

“Climate change is a threat multiplier in  the world’s most unstable regions.”

“From a national security perspective, climate change has the potential to affect lives (for example, through food and water shortages, increased health problems including the spread of disease, and increased potential for conflict), property (for example through ground subsidence, flooding, coastal erosion, and extreme weather events), and other security interests.”

These leaders are talking about fundamental shifts in ‘givens’ that require action, a joined up way of behaving, new ways of thinking, and new approaches. And our top business schools should be on the leading edge.

I first got interested in business schools ignoring the big elephant in the classroom two years ago when I was delivering a course on dominant business metaphors and implementing change. I wanted to say one line – one sentence inviting students to ponder how the nature of sustainability planning would be different if organisations, in addition to approaching business as a ‘competitive sport’, also approached it as a living organism. The professor who brought me in said ‘no’ – that the MBAs would feel they were being hijacked away from the course they had paid for. There was a specific elective for sustainability – and outside of that – best not to mention those issues.

Over the past few months, I’ve been speaking with several top MBA programs in Europe. Each is saying that leaders need, more than at any other time in history, to be able to lead in the presence of ambiguity, and to be able to perform collaboratively with high levels of uncertainty. Applied Improvisation skills are rather good for that, which is why I’m there in the first place.

What I find interesting in talking with these top MBA programs is that many are not contextualising the WHY of this new emphasis. Not addressing why managers/leaders would need to be so good at ambiguity.

“Growth for the sake of growth is the ideology of the cancer cell.” – Edward Abbey

I sat up when I saw this quote. It was refreshing to see in a lecture to potential MBAs at a leading business school in the Netherlands a few weeks ago. During my time at the school, two of the guest lecturers talked about sustainability – kind of…

The first lecturer used the Abbey quote (Abbey is a renown outspoken sustainability activist) and talked about the need to create ‘sustainable businesses’ quickly dismissed the notion of ‘sustainable’ as being linked to any ‘environmental’ issues… – it was about a business which can keep going, despite ‘adversity’. Given what scientists are saying about increasing disruptions over climate change, peak oil, peak minerals, peak water, how could adversity due to these factors not be mentioned?

The other lecturer had just hosted a biomimicry event two weeks before and deeply cared about the environment and sustainability. He works with top leaders in the best companies around the world on developing leadership skills. In his session, he talked about the profound need for leaders to be comfortable leading in the presence of ambiguity, but didn’t say why. In the break he confided that there are some groups with which you cannot talk about the environment directly. He had been gently testing the water with that day’s group and found he could mention it a bit…but only a bit. Several people were there for the express purpose of earning more money with an emphasis on value extraction, not particularly wealth creation/exchange.

Contextualising is a vital part of learning. The military does this routinely in their simulations – creating real world scenarios in the classroom. If we are facing a series of challenges (climate change, scarcity of water, oil, minerals, etc.) we must mention that as part of what leaders will face.

One initiative that gives me hope is the UN Principles for Responsible Management Education (PRME) initiative. The head of a leading MBA program in the UK turned me on to it. Finally – a global effort is being made to transform business schools and the Assocation of MBAs is part of it. In theory – that should mean that the taboo-ness of sustainability issues being explicitly mentioned, or mentioned only in specific electives – disappears.

As I continue to work with MBA programs, I will keep you posted on what I see going forward in this arena. And if you know of any best practice in this area – please post it here. Let me know!

Sustainable Energy Security: Strategic Risks and Opportunities for Business

Posted on 12 July 2010 | by Jay Kimball | 3 Comments

Lloyds of London, the insurance market, and Chatham House have published a white paper on Sustainable Energy Security that details the risks and opportunities for business.

Lloyd’s CEO, Dr. Richard Ward, doesn’t mince words in his foreword to the white paper:

This report, jointly produced by Lloyd’s 360 Risk Insight programme and Chatham House, should cause all risk managers to pause. What it outlines, in stark detail, is that we have entered a period of deep uncertainty in how we will source energy for power, heat and mobility, and how much we will have to pay for it.

Is this any different from the normal volatility of the oil or gas markets? Yes, it is. Today, a number of pressures are combining: constraints on ‘easy to access’ oil; the environmental and political urgency of reducing carbon dioxide emissions; and a sharp rise in energy demand from the Asian economies, particularly China.

All of this means that the current generation of business leaders – and their successors – are going to have to find a new energy paradigm. Expect dramatic changes:

Prices are likely to rise, with some commentators suggesting oil may reach $200 a barrel.

Regulations on carbon emissions will intensify.

Reputations will be won or lost as the public demands that businesses reduce their environmental footprint.

The growing demand for energy will require an estimated $26 trillion in investment by 2030. Energy companies will face hard choices in deciding how to deploy these funds in an uncertain market with mixed policy messages. The recent Deepwater oil spill shows all too clearly the hazards of moving into ever more unpredictable terrain to extract energy resources. And the rapid deployment of cleaner energy technologies will radically alter the risk landscape. At this precise point in time we are in a period akin to a phony war. We keep hearing of difficulties to come, but with oil, gas and coal still broadly accessible – and largely capable of being distributed where they are needed – the bad times have not yet hit. The primary purpose of this report is to remind the reader that all businesses, not just the energy sector, need to consider how they, their suppliers and their customers will be affected by energy supplies which are less reliable and more expensive.

The failure of the Copenhagen Summit has not helped to instil a sense of urgency and it has hampered the ability of businesses – particularly those in the energy sector – to plan ahead and to make critical new investments in energy infrastructure. I call on governments to identify a clear path towards sustainable energy which businesses can follow.

Independently of what happens in UN negotiating rooms, businesses can take action. We can plan our energy needs, we can make every effort to reduce consumption, and we can aim for a mix of different energy sources. The transformation of the energy environment from carbon to clean energy sources creates an extraordinary risk management challenge for businesses. Traditional models that focus on annual profits and, at best, medium term strategies may struggle. Parts of this report talk about what might happen in 2030 or even 2050 and I make no apology for this. Energy security requires a long term view and it is the companies who grasp this who will trade on into the second half of this century.

Executive Summary

Businesses which prepare for and take advantage of the new energy reality will prosper – failure to do so could be catastrophic.
Market dynamics and environmental factors mean business can no longer rely on low cost traditional energy sources.
China and growing Asian economies will play an increasingly important role in global energy security
We are heading towards a global oil supply crunch and price spike.
Energy infrastructure will become increasingly vulnerable as a result of climate change and operations in harsher environments.
Lack of global regulation on climate change is creating an environment of uncertainty for business, which is damaging investment plans.
To manage increasing energy costs and carbon exposure businesses must reduce fossil fuel consumption.
Business must address energy-related risks to supply chains and the increasing vulnerability of ‘just-in-time’ models.
Investment in renewable energy and ‘intelligent’ infrastructure is booming. This revolution presents huge opportunities for new business partnerships.

A change in the energy market balance between East and West

Advanced economies remain the biggest consumers of primary energy per person but by 2008 non-OECD countries led by China and India had outstripped them in terms of the share of world demand. This shift began in the 1990s, partly because manufacturing shifted eastwards. Meanwhile, lower population growth, de- industrialisation, greater efficiency, higher fuel prices and a concern for the environment are lowering demand for oil-based fuels and coal in the OECD.

These consumption trajectories mean there is likely to be a tipping point in 2015 when countries in Asia-Pacific need more imported oil in total than the Middle East (including Sudan) can export.

The white paper goes on to detail market forces, energy trends, risk and opportunity. This is recommended reading for business and government leaders and risk managers.

Walmart Partnering with Patagonia on Sustainable Business Practices

Posted on 01 July 2010 | by Jay Kimball | 2 Comments

A recent article in Forbes describes how Patagonia, one of the early thought-leaders on sustainable business practices, and Walmart, are partnering to help Walmart move up the sustainable business learning curve fast. The article emphasizes the need for not just being sustainable inside the business, but up the supply chain as well.

Highlights of the Forbes article:

Patagonia is working with Walmart to develop a sustainability index for its products
This initiative is being driven by Walmart CEO, Lee Scott, working with Patagonia’s CEO, Yvon Chouinard.
Walmart CEO Lee Scott first articulated a sustainable vision for Walmart in 2005 saying Walmart “must operate in a world that is healthy.“
Walmart is assessing things like how much water is consumed in the manufacturing process of a product, whether pesticides are used, impact on climate change, energy efficiency, etc.
Walmart wants to place a scorecard on its store goods that rate products on eco-friendliness and social impact.
Walmart is evaluating its suppliers and will give preference to those who best comply.
Patagonia has helped others, including Nike, Gap, REI, and North Face.
Nike has gone on to form GreenXchange, a consortium of ten companies (among them, Yahoo) that will trade eco-friendly intellectual property.

Most businesses I talk with want to do the right thing in terms of caring for the planet, but it rarely shows up in their mission statements or operational imperatives. However, if you ask any business person if their business depends on a healthy customer and a healthy supply chain, the answer is an obvious “Yes!”

Sustainable Business Interdependence

When I talk with business about strategies and tactics for sustainable business, we invariably come to this picture:

If a business confines their view of global issues to within their own business, they might think that climate change, water scarcity or high energy costs don’t impact them. They might say “Well, we don’t use much water, so that’s not an issue for us.” But if the view becomes more expansive to include the supply chain and the customer, they find increased risk to “business as usual.” Everyone interdepends on everyone else. Just as the proverbial rising tide lifts all boats, if the tide falls for one, it falls for all.

For example:

Water tables are falling rapidly in China. If a production plant in China, making product for Walmart, depends on water for the production, and the price of water suddenly rises, or access is limited by government edict, that impacts Walmart cost of goods and product flow.
If Walmart customers can’t afford to buy as much because they are spending too much on energy bills and gas expenses because the price of oil is at $120 a barrel, Walmart top line revenue growth declines.

Even if a business isn’t selling directly to “the consumer,” there is risk. If a company has businesses as a customer segment, they must understand how those businesses will be impacted. For example, if Walmart customers choose to spend less money at Walmart because of rising energy prices or fear of losing a job, Walmart will place less orders with their vendors and vendor order volume will fall. So consumer wellbeing matters to vendors all the way up the supply chain.

Walmart is the biggest retailer in the world. They are taking the long view and understand the interdependence of their success with the health of their supply chain and customer base.

Regarding sustainable practices, as a business expands its field of view to include supply chain and customer, there are three key things to examine:

Mitigation – Understanding what impact global issues will have on the business and creating adaptive strategies and tactics to prepare. Shareholder value is protected.
Innovation – As a business understands the global trends and challenges, they can innovate solutions that will have real value for their business, supply chain and customers, and beyond the, open new markets and opportunities. Shareholder value is increased.
Advocacy – Are the steering directions a business gives to representative associations, lobbying firms, chambers of commerce and state and federal representatives in alignment with new found adaptive strategies and tactics?

Thinking like Walmart – What can a business do to ensure a healthy world?

Perhaps we should call it the The New Trickle Around Economy!

More on this in a future post. For now, here are some photos I took while visiting Walmart headquarters, in Bentonville, AK, for a book I am writing on sustainable business strategies. These pictures were taken while touring one of Walmart’s flagship stores in Fayetteville, AR.
