Technical Guidance & Practical Renewable Energy Insights
Practical early-stage guidance covering micro hydro, grid connection, wind siting, battery storage and feasibility considerations.
Explore the Key Topics
These pages are intended to support early-stage understanding, project screening and practical decision-making before detailed design work begins.
Battery Storage
Explore the role of battery storage in system flexibility, export control and site optimisation.
Solar PV Overview
Understand how solar PV systems work, how orientation affects output, and key design considerations.
Solar Calculator
Estimate system size, panel count and expected annual generation based on roof dimensions and layout.
Grid Connection
Understand the early-stage issues that affect connection strategy, export limits and project design.
Finding a Grid Reference
A simple guide to identifying the correct grid reference for renewable energy project work.
Preliminary Studies
See what early-stage technical review can achieve before committing to detailed design or procurement.
Estimating Micro Hydro Head
Understand gross head, early-stage map-based estimation and why usable vertical drop matters.
Estimating Micro Hydro Flow Rates
Review practical ways to build an early understanding of likely water availability at a site.
Calculate Hydroelectric Power
Use head, flow and efficiency assumptions to develop an early-stage indication of hydroelectric output.
Wind Turbine Siting
Review practical siting considerations that influence safety, performance and project viability.
Estimating Wind Speed
Learn the main considerations when building an early-stage picture of wind resource.
Wind Speed Calculator
Use a grid reference or postcode to return a historic NOABL-based wind speed estimate for early-stage wind turbine site screening.
Designed for Early-Stage Project Review
The Insights section is intended to help landowners, farms, estates and renewable asset owners make more informed early decisions.
