There is increasing pressure on governments and commercial organizations to develop more sustainable approaches to energy supply and usage.
Already, massive investments have been made in installing renewable sources including wind and solar energy and the US EIA (Energy Information Administration) estimates that about 11% of energy consumed around the world currently comes from renewable sources.
The move toward sustainable energy is already having positive environmental and health effects. It is also part of the mix which is producing micro- economic gains as energy costs are lowered and exposure to ‘green’ taxes is reduced. We also benefit politically, as dependence on imported energy is reduced and macro-economically when energy is produced ‘domestically’ by local companies employing local labor.
Sources such as biomass and biofuels, which emulate and replace traditional hydrocarbon systems, are suited to the grid and the usage patterns we have developed over the past 100 years of electricity generation and consumption. These energy sources still generate greenhouse gases but, when well-managed, create their own shorter and sustainable carbon cycles, making them useful replacement technologies for traditional coal and gas powered power stations.
Cleaner sources such as solar and wind power have, in operation, little environmental cost and are better for the planet. However, the way in which they harvest power is highly dependent upon prevailing weather patterns and in the case of solar; seasonal and diurnal effects. Such energy ‘farms’ are often very large and located in remote regions and may require dedicated access to grid transmission lines.
IEM’s core business has long been the design, production and implementation of switchgear in large scale industrial applications. Our low and medium voltage switchgear is already employed in substations supporting renewable energy facilities so that the power produced across the site is combined and converted and made ready for distribution over the regional or national grid.
IEM Power Systems is also pioneering technologies that provide flexibility between variable solar and wind power supplies and rigid demand from the grid.
In order to balance steep fluctuations in supply against the more gentle variations in demand, a technology is required to intervene when solar and wind power into the grid is lost; as the wind drops or clouds block direct sunlight. These interruptions may only be for only a few seconds, but to those who manage our power grids, and organizations and individuals who depend upon a steady flow of energy, such variations in supply are a significant problem.
Whatever application your facility requires IEM Power Systems can work with you to develop an optimized solution to maximize the benefits of your investment in renewables and energy storage.
