Renewable Energy Feasibility and Design

solar thermal systemNarec Distributed Energy are involved in the feasibility and design of many renewable energy systems, including solar thermal systems

We provide Renewable Energy Feasibility services on a wide range of low carbon technologies, including photovoltaics, biomass & biofuels, solar thermal, heat pumps and combined heat and power (CHP). Because Narec Distributed Energy is completely independent from manufacturers, customers can be safe in the knowledge that recommendations are based purely on sound technical information.

Energy Demand

We calculate the energy demands of buildings, be they thermal or electrical or both. This is performed using benchmarks, SAP, analysis of bills, installation of meters, and in the case of new builds we can perform detailed thermal modelling of buildings

Technical Feasibility

We perform detailed technical feasibilities, identifying the best technologies for a particular purpose, and providing detailed estimates of the energy production.

Economic Feasibility

Based on our understanding of financial incentives, we calculate the payback times and financial yields for the technologies considered. As UK government incentives change rapidly, we keep a keen eye on political developments on a daily basis. Financial mechanisms considered include the Renewbles Obligation, Contracts for Difference, Feed in Tariff, Renewable Heat Incentive, Enhanced Capital Allowance, and various options for the sale of energy, including ESCos, private over public wire, direct sales to the grid and others.

Grid Connection

For large scale electrical commercial renewable energy systems, we work with the client and the local Distribution Network Operator to get the best deal on connecting the renewable energy system to the electricity grid.

Heat Network Connection

In the case of biomass and Combined Heat and Powr systems, we work with the client to understand the requirements of connection to existing heat networks, or help specify the type of heat network needed.

Community Energy

We work with community groups, assisting with funding applications, and performaing detailed renewable energy feasibilities for a range of technologies


We provide a wide range of accredited and bespoke training courses on renewable energy for installers, developers and financiers. Full details can be found on [link to training page] but some of the most popular courses include:
