Memoori published a report titled “The Smart Grid Business 2011 to 2016,” which tackles the major issues and challenges facing the industry over the next 5 years.
The report estimates that to achieve full penetration of the world’s existing grid together with future extensions to 2030, will require an investment of some $2,000 billion on pure smart grid equipment at installed prices.
There is no question about demand for smart grid — in the long term it is inevitable. But we believe that investment funds are the weakest link in the chain and could cause a slowing down in growth.
This can be overcome if the utilities are allowed to recoup the investment over time by increasing their charges for electricity. This will be the solution in Europe but is unlikely to be politically acceptable in North America, despite the fact that prices there are less than half that of most European countries.
In the U.S., according to figures published by the Edison Electric Institute, electric utilities in 2010 had revenues of $371 billion producing a net income of $68 billion and a net after tax profit of $27 billion, whilst retained profit after dividend payments was $10 billion.
Of this transmission and distribution is unlikely to have contributed more than 30 percent. Pure smart grid average annual expenditure in the U.S. will need to run at $22 billion and should peak at around $35 billion in 2021. This simply cannot be achieved without a significant hike in the tariff rate that the regulators will be reluctant to authorize.
Utility companies are not the most profitable operations and they are going to need help with financing the development of the smart grid. In most countries the electricity grid needs refurbishing in any case, so additional expenditure will have to be found, or the basic requirement of electricity supply and reliability will not be satisfied; let alone the pressing need to reduce carbon dioxide levels.
Smart grid is part of the clean tech business and so far it has only received a relatively small sum of investment from private and public sources; compared with the largess heaped on other parts of the business.
However, under government programs in the U.S. alone some $4.5 billion has been awarded for investment in smart grid projects in the electrical utilities business. In addition at least 27 American Recovery and Reinvestment Act projects are being funded from the almost $5 billion allocated to the U.S. Department of Energy for grid modernization projects.
Our market sizing figures show that the U.S. is currently the global leader in investment in smart grid. In view of the size of its generating capacity and electrical transmission system this should not be a surprise, but the smart grid stimulus programs have pump-primed investment and played a major part in taking the U.S. forward.
In Europe, finance has been made available through E.U. programs and some demonstration projects are being financed within member state initiatives but nothing on the scale of that provided in the U.S. In China, the state has orchestrated the program for the nationalized utilities to carry out a major program of investment, directly and indirectly they will finance it.
This industry will still need stimulus funds for some years if it is to continue developing at a fast pace and play its proper role in assisting with the delivery of a comprehensive green energy solution. But with so many countries around the world now looking to reduce public expenditure, government funding for smart grid is unlikely to go unscathed.
Information technology and communications companies would almost certainly be interested in joint collaboration with the utility industry on all aspects of the Internet of Things and they have the funds to invest.
Smart grid will deliver a better return on investment than is currently realized in the utility industry; but this has yet to be proven in most sectors of the business because full-scale tests and demonstrations have not yet been completed.
The exception to this is smart meters. In the U.K. a typical smart sub metering installation in the commercial / industrial market will provide a return on investment in 10 to 14 months subject to enhanced capital allowances, allowing offset of the total cost of installation against corporation tax in year one.
In most countries smart meter installations in the residential market are being financed directly and indirectly by the building owners / occupiers without so far placing too much burden on the utility companies.
In the U.S., smart meters save consumers $60 to $180 per year, according to the Energy Information Administration for an outlay of $500. A recent DOE study showed that when consumers can track their energy usage through smart meters, their usage declines by as much as 15 percent.
For the utilities smart meters provide value through automatic billing reducing costs and better management of cash flow. Full AMI will provide real time data to help balance out supply and demand and reduce wastage. Every unit of electricity saved at the point of usage will save 3 units at the generator set. As the volume of equipment rises, prices will fall and ROI will increase, conversely energy prices are almost certain to rise.
