RENEWABLE ENERGY


SUSTAINABLE SOLUTIONS THAT DELIVER MEANINGFUL ROI


For organisations under pressure to control energy costs and demonstrate progress on sustainability, green solutions increasingly need to deliver on both fronts. Joe Wal, head of


operations at Plug Me In, looks at how renewable energy technologies can help organisations cut costs, reduce emissions, and achieve a measurable return on investment (ROI)


T


here is a growing range of renewable energy solutions that can help businesses reduce


costs while making measurable progress towards carbon reduction and Environmental, Social and Governance (ESG) targets. For energy and procurement managers, however,


choosing what to invest in is not simply a question of selecting the latest technology. The solution needs to fit the site, how energy is consumed, and the organisation’s wider objectives. Get that right, and renewable energy can deliver practical and financial benefits alongside environmental ones.


AN INCREASINGLY DIVERSE RENEWABLE


ENERGY OFFERING Solar is one part of a wider and increasingly diverse renewable energy offering. While solar panels have been around for decades, advances in lightweight modules are expanding the types of buildings and sites where solar generation can be considered, particularly where conventional panels may be unsuitable because of structural constraints. Energy storage is developing alongside generation,


giving organisations more flexibility over how and when electricity is used. Battery systems can store surplus electricity for later use, helping increase the proportion of onsite generation that is consumed. Combined with smart energy monitoring and


management, generation and storage systems can also provide a clearer picture of consumption and highlight opportunities to improve efficiency.


BEYOND TODAY’S TECHNOLOGY Renewable energy is also moving beyond the


technologies that are already commercially established. Research into generating electricity

from rainfall is one example, with recent work exploring hybrid photovoltaic-triboelectric systems that can harvest energy from sunlight and raindrops. While still at the research stage, the work illustrates how the renewable energy landscape is evolving. The point for businesses is not to wait for future


technologies to become commercially viable, but that systems designed with flexibility in mind can accommodate new technologies as they become available, helping organisations improve performance without starting again from scratch.


FINDING THE RIGHT SOLUTION Renewable technology is rarely an off-the-shelf


purchase. Before selecting a system, organisations need to understand how energy is being used across the site, when demand peaks, and where opportunities exist to reduce consumption or make better use of generated power. With solar projects, for example, the consumption


profile can influence the size and configuration of the system, while also determining whether battery storage or energy management could add further value. Roof suitability, structural considerations, existing electrical infrastructure and future energy requirements also need to be considered. The strongest outcome is not necessarily


delivered by installing the largest system, but by selecting the right technologies for the organisation’s actual operations. A Bedford-based customer was keen to invest in


renewable energy technology and, after reviewing the available options, concluded that solar would provide the most effective solution. However, because of the building’s structural characteristics,


installing conventional solar panels were unfeasible. Instead, two lightweight panels capable of


delivering 1,653 kWp of capacity and an estimated 1,524,353 kWh of clean electricity per year, were installed. With an ROI period of just three years, the system is expected to save an estimated 294 tonnes


of CO2 annually and deliver projected savings of £6,313,771 over 20 years. The project demonstrates how advances in


solar technology can make renewable generation viable for previously challenging sites, while delivering a measurable financial return, significant carbon savings and progress towards wider sustainability goals.


LONG-TERM VALUE Choosing the right technology is only part of a


successful renewable energy project. Once installed, systems need to be monitored, maintained and reviewed to ensure they continue to perform as expected and deliver the anticipated financial and environmental benefits. Access to technical expertise and 24/7 support can


help identify issues quickly, minimise downtime and maintain performance. An end-to-end partner can also provide continuity as requirements change, keeping track of developments and identifying opportunities for upgrades. A system that can be monitored, maintained


and upgraded over time gives organisations the flexibility to respond to changing energy demands and adopt new technologies while cutting costs, reducing emissions, and achieving meaningful ROI.
