Energy is boring!

London, 30th October 2008

Energy_is_boring_NT_e

Energy is boring. People don’t sit around the pub talking about energy. You can’t see it or touch it. It doesn’t engage or entertain. You can’t compare it and there are no prizes. It’s the same for everyone. And until recently it wasn’t very expensive.

What people talk about is: the weather, work, relationships, family, sport, TV, films and news. All these things are tangible, engaging and generally competitive. The weather is changeable and local. Sport has winners and losers. We give our allegiance to a team and we rejoice when they win and swear at the referee when they don’t. TV informs and educates and entertains us. It is part of the zeitgeist and we talk about it over the water cooler because it’s something we have in common.

The cost of energy has shot up and that makes it matter more. But here at Onzo we’re making energy more interesting for good reasons. We’re making it visible; to help people learn about it; we want people to compare their usage with others; we’re trying to make it personal and entertaining; bridging the gap between awareness and action; nudging people into action; helping people to reduce waste, lower their bills and to curtail carbon emissions.

Who knows, your local might soon be noisy with positively charged energy jabber.

Onzo submits proposals “A Blueprint for Green Homes”

London, 26th October 2008

This week is the Energy Saving Trust’s 12th annual Energy Saving Week. As our main contribution to this event, Onzo has published a manifesto for improving the energy efficiency of the UK housing stock, which is responsible for around a third of all carbon gas emissions. Our comprehensive proposals, “A Blueprint for Green Homes” is found below. They have also been sent to the new Department for Energy and Climate Change as part of our drive to influence government thinking. More.

A smart guide to smart metering

London, 22nd October 2008

Automated Meter Reading (AMR) is a forerunner of smart metering. The essential purpose of AMR was to replace the conventional billing process: using information and communications technology instead of manual meter reading. It ensures that accurate readings are sent regularly to an energy company so that customer billing can be accurate and timely. But it wasn’t long before people realized that there is much more that could be done with the infrastructure required to automate meter readings.

So smart metering can be broken down as follows:
1. A more intelligent meter – smart meter – than the ones in our homes currently. ‘Smart’ refers primarily to its ability to communicate, though ‘smart’ may also include increased accuracy and   other functionality. In fact it turns out that there is an extremely long list of things that ‘smart’ meters could do. We’ve included some of these things at the end. But it’s worth noting that there is no consistent definition of what constitutes ‘smart’.

2. An advanced metering infrastructure – AMI – which enables information to be exchanged between the meter and the energy supplier

3. Meter data management – MDM – software that stores and processes data

4. Sometimes an energy display is included in the scope of smart metering

In short, most smart meters communicate their information over a Local Area Network to aggregators, which bundle this up into a larger package of information. The aggregators then relay the bundled information to servers over a Wide Area Network. The information then gets stored and processed by the servers. Different options are available for the communications infrastructure. These include plc (power line carrier – the existing electricity wires to you and me), gsm/gprs (the mobile phone network), mesh radio (radio devices talking to one another wirelessly), pstn (the telephone network), and ip (the internet).

Issues with smart metering
1. Because its origins lie in AMR, the approach that is often taken is i) replacing a manual data collection process with IT and ii) seeing what else can be done with that IT and the information that is collected. The approach that should be taken is i) understanding customer needs and business needs and ii) developing cost effective solutions to those needs. The energy industry’s priorities are generally, and in order, generation; distribution and; billing. This is a long way removed from many industries that put the customer first. The energy display is a good example of this – it is generally little more than a meter out of the cupboard when it could be a key customer touchpoint.

2. Smart metering is an expensive thing to implement because it consists of a lot of new hardware that needs to be fitted by trained personnel, in a lot of homes, with expensive software that needs to integrate with legacy systems. Given the cost, you wouldn’t want to be going back any time soon to improve it. But there are dangers that the AMI component – the communications piece – and the smart meter itself get specified in a way that is limiting to future development. Smart metering has an Achilles heel that could turn out to be smart metering’s Y2k. There are three components:
a. Data granularity and quality. Because smart metering is a replacement billing process (see 1. above) readings are typically every ½ hour because this is the level of granularity that people think is needed for time of use tariffs. However, powerful information that helps the customer could be obtained through increased granularity – possible as fine as one second data.
b. Bandwidth. Because of a. bandwidth is assumed to be very small. But this fails to account for the possibility of finer granularity of data or future uses to which the communications infrastructure might be put. Home healthcare, for example, has very similar requirements.
c. Communications technology. The technologies that are currently being deployed will be very different from those that will be available in 10 years time, but the meters that are going out now have no way of being able to upgrade the communications hardware.

3. Because energy supply is a regulated monopoly in many (particularly North American) territories, solutions must be universal. There are also often constraints on these companies that prevent them from creating new revenue streams. The upshot of this is gold-plated solutions that can’t be leveraged for other purposes whose entire cost is passed on to the customer.

4. Governments and regulators find it hard to resist the call for something ‘smarter’, and ‘smart metering’ as a term is carelessly used as a solution to all ills. Governments and regulators need to be clear about their objectives (which might include reduction in greenhouse gas emissions, fairness for customers) and not rubber stamp solutions that have the flaws identified above just because they are presented as ‘smart’.

Other relevant terms
Demand-Side Management (DSM) is an aggregate term to describe everything that happens on the customer’s side of the meter. It includes Demand Response – when an energy company turns down or switches off the customer’s appliances to reduce demand so that the generation/distribution infrastructure can cope with a peak in demand. DSM also includes energy displays, websites, appliance monitoring and control.

Energy displays present information to the consumer on their energy use. At the core of most is a reading of real-time usage. This information can be obtained before smart metering is rolled out by means of a sensor, which is clipped onto the cable between the meter and the consumer unit. Post smart meter roll-out this information can come directly from the meter. Energy displays are also called RTD (real-time display/device), IHD (in-home display/device), energy monitor, energy meter, electricity display device, and also, inappropriately and confusingly, ‘smart meter’. Onzo likes ‘energy display’ because it’s simple and clear and has no overtone (unlike monitor which sounds a bit big brother) and isn’t going to turn into a meaningless acronym.

Smart grid is the term widely used to describe more effective distribution of electricity – as today’s alternating current power grid was created in 1896 it’s not surprising that there are some efficiencies which can be obtained by effective monitoring and management. Distribution is what happens to electricity between the power station and the meter. There are two ways in which the smart grid can extend beyond the meter. The first is when customers generate their own electricity and feed this into the grid. This is called microgeneration and includes combined heat and power plants, wind turbines, solar panels (solar pv), and (less likely) hydro-electric power from the stream in your garden. The second is when customers plug in their electric (and hybrid) vehicles; this means that there are lots of batteries attached to the distribution network that otherwise isn’t able to store electricity. Because smart grid goes beyond the meter, but one is still required, smart metering is sometimes assumed to be a subset of smart grid, although it’s perfectly possible to have a smarter grid without smarter meters and the other way round.

‘Smart’ meter functionality
Examples of the functionality specified in a ‘smart meter’ include:
• Local Area Network (LAN) communications interface – the fundamental piece of sma
rtness that allows the meter to communicate outside the home, enabling remote reading, other comms and controls. Normally this is either PLC, Mesh radio, GSM or IP. This is also sometimes known as the WAN (Wide Area Network)
• Home Area Network (HAN) communications interface – to allow a range of other devices (such as in-home displays and direct load control equipment) to access the communications network through the meter. This might also allow one utility meter to talk to another within a home, enabling meter readings from all of them (electricity, gas, and water) to be returned through a single communications infrastructure. Common solutions for the HAN are Zigbee, Z-Wave and Wireless M-Bus.
• Real-time reads – to enable display of useful information in the home, real-time or near real-time reads are required. This is additional to the much less frequent billing reading.
• Remote load control – to allow devices to be turned on or off by a pre-set pattern or the energy company on demand. This uses the HAN to communicate with the loads that are being controlled.
• Export metering – the ability to measure electricity flowing out of customers’ premises, supporting tariffs for distributed generation, including microgeneration.
• Remote connect/disconnect – the ability for the electricity supply to be cut off and restored on demand by the energy company.
• Outage detection – to identify when power is and isn’t reaching a home.
• Meter tamper detection – to monitor whether the meter is accessed without authorisation.
• Remote time synchronisation – to keep the meter’s internal clock synched.
• Quality of supply measurement and recording – to detect and record changes in voltage and other power quality issues.
• Appliance inference – to identify which appliances are using energy in the home using algorithms that recognize electronic signatures and patterns of use.
• Display – a screen on the meter itself which shows energy usage information.
• Data entry – a keyboard in essence (could be touchscreen) giving the consumer the ability to input information.
• Switchable between credit and prepay – ability of the energy company to change meter functionality
• Payment – ability to make payments via the meter itself
• Encryption – to ensure that information sent over the communications network can be ‘read’ by authorized personnel only
• Self-configuration – so that a meter can set itself up when it is installed
• Upgradable – the firmware in the meter can be remotely upgraded over the AMI network
• PHEVs – the ability to connect plug-in hybrid electric vehicles (PHEVs) as well as fully electric vehicles

Joel Hagan’s letter in The Times

London, 10th October 2008

Today’s Times carries a letter from Onzo’s Chief Executive, Joel Hagan. Joel calls for a dramatic reduction in the number of Cabinet Ministers and government departments ,with a completely new structure to the government to ensure more coherent policy-making and eliminate overlapping responsibilities.

The letter has attracted the attention of The Times’ online bloggers. “Far too sensible with Sir Humphrey and his civil service preserving their empire”, wrote Charles Brockett-Pugh from Sandhurst.

Onzo moves on

London, 10th October 2008

Onzo has a new home. Last Friday we said a fond farewell to our office in Denmark Street, Soho, and decamped down the Charing Cross Road to Great Newport Street, a stone’s throw from both Trafalgar Square and Covent Garden. The distance between the two locations is no more than half a mile, but the change marks a significant stage in Onzo’s journey. When we moved into Denmark Street, only nine months ago, we were a company of eight people: we currently have 24 staff and plan to increase the number to around 40 by the end of January 2009 as we enter the next phase in the development and marketing of our products and services.

We are now ensconced in the former rehearsal rooms above a small theatre where, for the first time, we are able properly to bring together our design studio and office under one roof. We are also embodying the principle of sustainability by putting a fine old building to a dynamic and innovative new purpose. One small step, but one giant leap for Onzo!

Fuel Poverty: Too Little But Its Never Too Late

London, 9th October 2008

Joel Hagan calls for a long term approach to combating Fuel Poverty.

A few years ago the Government claimed to be winning the war on fuel poverty. Ministers boasted that four million households had been lifted out of fuel poverty between 1996 and 2004. All of a sudden they seem to be in retreat. Between 2005 and 2006 the number of fuel poor rose by around a million to stand at roughly 3.5 million (around 14% of all households) and some estimates double the figure to seven million by the end of 2008.

Back in 2001 fuel prices were at their lowest in real terms since 1974. The original fuel poverty strategy document of that year said: “The main cause of fuel poverty in the UK is a combination of poor energy efficiency in homes and low incomes”. It went on to suggest that a reasonable range of price movements between 1999 and 2010 was +15% to -10% in real terms for domestic gas prices and +5% to -2% for domestic electricity prices. This has not exactly been bourn out by events. In August 2008 alone domestic electricity prices increased by around 20% and gas prices by around 30%, following 15% increases in January. But the sudden and steep rise in fuel prices should not be allowed to distract us from the underlying issues that drive fuel poverty. They remain the same – poor efficiency and inadequate incomes. They affect us all to varying degrees; and the government has failed to tackle them adequately.

A windfall tax is not the answer. Windfall taxes alienate business, which likes certainty in earnings and does not want profits periodically diverted to the Treasury when it is short of cash. We need energy companies to invest in the UK, in generation, distribution and metering; any diversion of funds will impact capital expenditure plans. The legal process to impose a windfall tax would be drawn out. Hypothecation, the devotion of tax revenue for specific purposes, although it happens from time to time, is not generally the way our tax system works in principle.

In the debate about fuel poverty, pre-payment meters are usually demonised, but they are not generally the root of all evil: in fact only 25% of pre-payment meter customers are fuel poor. Pre-payment meters are used by many people in much the same way as pay-as-you-go mobile phone contracts – Energywatch reported that 66% of all customers choose pre-payment meters to control their energy spending and Ofgem research found that the majority of customers are happy with this method of payment. The number of pre-payment meters has risen in recent years both as a (preferable) alternative to disconnection and as one way to repay accrued debt.

Pre-payment meters are more expensive to install and administer than other methods of payment and some energy companies pass this cost on to the customer. But it is not necessarily right to criticise them for passing on this cost, any more than it would be to condemn them for sharing with their customers the benefits of cheaper payment processing methods. However, it is right to ensure that those methods – direct debits and online billing – are available to all, and that they are explained to people in such a way that their concerns about them are allayed, as Ofgem is demanding.

It is good that the government has secured a commitment from the energy companies to spend £910m over three years on energy efficiency. UK housing stock is thermally inefficient, probably because we have a temperate climate with no great extremes of heat or cold and because energy prices were low while the North Sea remained productive. But as large a sum as close to a billion pound sounds, it does not go far. It will probably improve the insulation of somewhere between 100,000 and 200,000 homes in each of the three years – a drop in the ocean when there are around 22.5 million homes in the UK.

According to the definition of fuel poverty enshrined in law, in the Warm Homes and Energy Conservation Act 2000: “a person is to be regarded as living ‘in fuel poverty’ if he is a member of a household living on a lower income in a home which cannot be kept warm at reasonable cost.” This definition conflates several issues: 1. energy prices; 2. household income; 3. energy efficiency; and 4. vulnerability to low temperatures.

1. The key to containing energy prices is the development of a long-term generation strategy because price is a function of supply and demand. This strategy needs to set out what proportion of energy should be generated by nuclear, cleaned-up fossil fuels, renewables, local schemes, and micro-generation. It needs to take account of exposure to risk, currently called ‘energy security’.

2. Household incomes are driven by work, pensions, tax credits, disability allowances and other benefits. Vulnerable people should be able to pay for the necessities of life and payments should keep pace with necessities. Benefits such as winter fuel payments are directed to the elderly but exclude other relevant categories: the very young, those will breathing difficulties.

3. Energy efficiency can be sub-divided into energy performance of dwellings, the efficiency of a dwelling’s heating technology, and individual behaviour. Heating (space and water) accounts for 60% to 80% of domestic energy use. Around 18m homes are owner-occupied; 3m are privately rented; 2m have social landlords, and 2.5m are under local authority control. The obligation on landlords to have an Energy Performance Certificate without an obligation to act on it is pointless. Unfortunately, the heating technologies that cost least to install are often those which cost most to run. There needs to be a requirement on landlords to improve the energy performance of their accommodation. For privately owned and occupied accommodation, Energy Performance Certificates are welcome although they are now buried in the ineffectual and disliked Home Information Pack. Something more needs to be done to reduce the barriers to improving housing stock: the high capital cost and the extended payback period. The poorest must be given financial assistance with this.

High above all the other issues stands individual behaviour – seldom mentioned in relation to fuel poverty. It encompasses the purchase of appliances and the use of those appliances. We select appliances for our homes and use them. We set thermostats and on/off settings for central heating and hot water. Just as the fuel crisis of the 1970s taught us all about mpg, so now we need to learn about kWh. We need to know how much energy appliances use. We need to know what we could save by taking certain actions. We need prompts for when to use and when not to use. We need to know how much we use compared with other people. We need to know how we are performing against a target. At the beginning of the road to changing behaviour is accurate, timely and actionable information, from energy efficiency labelling on appliances to energy displays, from printed information to websites.

Fuel Poverty is an archetypal challenge to joined-up government. The establishment of the Department for Energy and Climate Change will go some way to achieve this as it will presumably take over the responsibility for fuel poverty, previously fragmented over a number of departments. We have yet to see how this will operate in practice, however, or how other departments with an interest in the area (especially the Treasury) will work with the DECC. Moreover, household incomes are still “owned” by Department of Work and Pensions, while issues relating to dwellings are dealt with by the housing and planning team at the Communities and Local Government Department so true co-ordination remains incomplete. Equally disappointingly, the important potential of the internet as a channel of information on energy usage seems lost in the Department for Culture, Media and Sport because it is assumed to be primarily a channel for entertainment. In fact it is fast becoming an essential utility.

What is irrefutable is that money to tackle fuel poverty should be directed at those with the lowest income, the least energy efficient dwellings, dwellings with outdated heating technology, and those that are most vulnerable to low temperatures – the youngest, the eldest, those with impaired mobility, and those with conditions that affect breathing. That means handouts until the infrastructural improvements can be made, and a much more vigorous programme to improve the energy efficiency of the UK housing stock.

Predictions about the rise in the number of the fuel poor are largely academic at the moment. It is only when winter bills arrive on the doormat in the spring that the true extent of the problem will be felt. In the meantime, let us hope people will not feel obliged to turn their heating down or off. If they do the government may be held responsible – through its failure to address the underlying issues in time – for a major tragedy.

Greenbang Report Calls for Encouragement for Cleantech Investment

London, 9th October 2008

Greenbang, the cleantech website, in collaboration with the Innovation Centre of Bath University and international communications consultancy Hill & Knowlton, has just published a report profiling 23 of what it identified as the best new companies in the cleantech sector. The businesses concerned, which include Onzo, encompass a wide range of activities including construction, energy, information and communications technology and transport. “We found”, says the report, “inspiring designs, technologies, business models. The UK has some incredible up-and-coming businesses”

It goes on, however, to argue that while many companies have succeeded in attracting initial venture capital, securing the investment needed to get to the next level of business development is considerably more difficult. The solution, it goes on, is more government support, in the form of longer-term policies to reduce political and financial uncertainty, and more incentives to encourage investors.

Onzo has been successful in raising funds. This is not necessarily typical, however, and it would be a mistake to assume there are unlimited sums available for cleantech start-ups in this country. Funds remain very difficult to attract. UK investors generally take a much more cautious and measured approach than their counterparts in the US, where the tendency is to back new businesses earlier, more indiscriminately, and with larger sums of seed capital.

There is a future for the best of cleantech here, but the climate is by no means easy and Greenbang is right that regulatory support is vital. For instance, recognition by the government that smart displays have an important role to play in promoting energy efficiency and reducing carbon gas emissions would give a very important boost to this potentially significant new sector of the economy.

Onzo contributes to Fuel Poverty debate

London, 8th October 2008

Onzo’s meeting on fuel poverty that took place as part of the fringe programme at the Conservative Party conference in Birmingham on Sunday 28th September was an important contribution to discussion of the issue. It was very well attended, both by delegates to the conference and representatives of numerous NGOs and voluntary organisations, and stimulated a vigorous debate on how to find long-term solutions to the problem to supplement the short-term expedients announced recently.

The speakers were Derek Lickorish, Chairman of the Fuel Poverty Advisory Group, and Eddie Hyams, Chairman of the Energy Saving Trust. Stephen Hammond MP, shadow transport minister and Vice Chairman of Citizens’ Advice, responded from the Conservative perspective.

Fuel poverty was one of the most frequently discussed social issues at both the Labour and Conservative conferences. Onzo attended many meetings on the subject and after reflecting on what we heard we have drafted an article setting out what we feel would be the most positive approach. A press release summarizing our arguments can be found in the press section and the full article will be posted here soon.
