FREE AS A BIRD - It is happening. Wind energy is providing bucket loads of energy that will be more useful with the kind of load leveling that battery and hydrogen storage can provide, to make better use of all that captured natural power. Windmills and sails had been working for mankind for hundreds of years before the discovery of electricity. These graceful machines can be located in isolated areas where winds are strong and reliable.
to their website, SSE has set four fundamental goals for 2030 which put sustainability at the heart of its business.
These four goals are:
GO AHEAD LONDON
SSE Enterprise is helping thousands of London commuters travel by electric bus after installing hundreds of charging points across the capital
SSE Enterprise’s work included Go-Ahead London’s ground-breaking Waterloo Garage development, which became the first, and currently only, all-electric bus garage in the country, complete with 43 charging points in 2016.
EV’S POTENTIAL IMPACT ON THE GRID
With various studies having found that EV owners currently tend to charge their cars at the end of their working day – coinciding with when energy demand is already at its peak – the major question being posed is this: how will the system be able to cope if charging habits remain the same when EVs are in much wider use?
To put the potential demand increase into some perspective, it is estimated the draw on the grid for each single EV is equivalent to that of an entire house. Thus, hypothetically speaking, if a network feeder line had 2,000 homes on it, and 400 of those households decided to charge their EVs at the same time in the early evening, then peak demand would rise by a massive 20 percent.
It is highly likely in this case that demand would far outstrip supply, resulting in such system chaos as transformer overloads, feeder congestion, and undue circuit faults. The consequences of this would be widespread power outages, bringing catastrophic disruption to everyday life.
SMART CHARGING FOR A SMARTER GRID
Therefore, the utilities industry and energy customers alike are left with a huge incentive to work within existing grid resources in order to maximise efficiency and cut down costs.
This is where EVs, if utilised as a demand-side response mechanism, could turn a problem into an opportunity.
Demand-side response, or DSR, relates to how consumers can use (or be incentivised to use) energy more intelligently in order to lower or shift electricity demand at peak times. As the National Grid puts it, DSR provides an important tool to “ensure a secure, sustainable and affordable electricity system…helping soften peaks in demand and fill in the troughs.”
In this context, far from adding to stress on the grid, EVs can actually become a key tool for grid stability, allowing electricity distributors to manage peak load and maintain reliability of supply.
It would mainly be used to reduce peaks in demand (i.e. when everybody gets home from work and plugs in their electric vehicle), although could also be used to provide high frequency response (an increase in demand in response to a rise in system frequency).
As an incentive, utility companies can offer EV owners monetary and/or non-monetary benefits in exchange for enrolment in a programme that permits controlled charging at the times when curtailment capacity is needed for the grid.
In the UK, Scottish and Southern Electricity Networks has already trialled DSR in this area with “breakthrough” success, while Electric Nation – a Western Power Distribution project – announced in March 2017 that it is to undertake the largest smart charging trial of its kind seen so far.
Preliminary results for this trial, presented by Electric Nation in early September 2017, back up the concept of smart charging as a “key solution to the impact of increasing numbers of EVs on the electricity network”.
Operating under a V2G system, EVs have the potential to become an extremely flexible asset – as well as providing transportation, they can undertake smart charging, thereby reducing demand as required, and can also export power back to the system.
As things stand, V2G has been tested in a small number of pilots; however a number of technical and regulatory issues need to be overcome before it can be widely and effectively used.
In significant news for the technology, the UK Department for Business, Energy & Industrial Strategy (in collaboration with the Office for Low Emission Vehicles and Innovate UK) announced in July 2017 that it is making £20 million available to businesses who want to help develop V2G projects around the country.
UK MAP - Draft infrastructure networked grid for the UK to kick-start EV service station building, aiming for a low carbon society that is sustainable and climate friendly by 2050 to comply with the targets set by the Climate Change Act 2008. This map is simplified and includes the Republic of Ireland for practical reasons. Supplied by and used with permission of Bluebird Energy Systems. If we use just the intersections endpoints as likely locations that would mean installing 60+ stations, that could recharge more than the 14,000 charge points in the UK as of January of 2018. Another 1,800 such stations at strategic locations could service all 25,000,000 million vehicles in the United Kingdom. Optimistic, but you have to start somewhere when conceptualizing. In the UK, the Department for Business, Energy and Industrial Strategy have introduced their Grand Challenges initiative, offering grants of up to 70% for SMEs in connection with mobility and clean energy.
According to Power-Technology.com, a website that provides market and customer insights in this sector, they listed these power companies (according to the 2018 Forbes calculation of net market capitalization, assets, sales and profit) as some of the world's the biggest utilities:
National Energy Board (Canada)
National Grid plc (formerly Central Electricity Generating Board UK)
HIGH VOLTAGE - Every country uses high voltage cables to transmit electricity via a grid. mostly over ground using steel pylons.
FROM SPACE EXPLORATION TO ZERO EMISSIONS - Developed to power satellites and spacecraft, the silicon solar panel is now a cost effective way of generating clean electricity. Ideal sites for the location of solar farms is land that cannot be used for farming, such as the deserts we have created.
