Solar PV generation offers a low-carbon alternative to burning fossil fuels. Alongside solar well-known environmental credentials, it is already in some cases the cheaper alternative to many thermal plants, making solar an increasingly viable option for investors. A booming market in Asia, improved manufacturing techniques and worldwide deployment on a large scale are just some of the factors ensuring that the cost of solar PV will continue to drop in the next 3-5 years.
Battery Energy Storage Systems (BESS) can be used to great advantage when integrated into variable renewable energy generation systems. As the generation profile of solar and wind sources cannot be guaranteed to match the load profile, the consumer may find themselves without energy when required or vice versa if renewable sources are used alone.
However, if the energy can be stored when excess energy is produced, it can be used when generation does not meet demand and economies can be realized at times where electricity from the grid is cheaper than peak times. Therefore, BESS can optimize the usage of power generated from the solar PV modules. As with solar PV, capital and operational costs of battery systems are dropping due to large-scale investment and mass production at a global level and are forecasted to do so for the next 3-5 years.
EV Charging Points are essential in moving to a low carbon electrified transport infrastructure. Most new infrastructure projects in the UK with any links to transport including EV charging stations are future proofing their designs by providing the conduit and connection points. This will allow for easy and quick retrofitting of the charging equipment and cabling in the future.
EV charging points are available in a range of sizes, allowing various charging speeds for vehicles of all sizes. This opens up potential for providing a supply for an all-electric bus fleet which is particularly relevant to park and ride Carport configurations. The low operating voltage of charging points (up to around 800V for bus charging points) allows integration into solar PV and BESS solutions without the need for expensive conversion equipment that would usually be required to feed renewable energy back into the grid.
