Elgin Energy

How can high quality ground data from drone surveys help with planning the sites for new renewable energy solutions? We work with Elgin Energy to get the data they need in order to prepare planning-ready site topo maps.

About ELGIN ENERGY

Elgin Energy is a leading international and independent solar+storage development platform

Elgin Energy is a full-service, utility scale, solar+storage developer bringing projects from origination through development. The company has a portfolio of projects in late-stage development totalling 6GW solar + 3GW storage across our three key markets of the UK, Australia, and Ireland.

Their Challenge​

Obtaining high-quality and high-accuracy photogrammetry data from a third-party supplier

Elgin Energy chose to work with us as a trusted supplier of data for sites which have potential in terms of the development of new renewable energies. Collection of high-quality, and high-accuracy drone photogrammetry data requires careful planning and assurances around quality, especially on large sites over 100 ha. We worked with Elgin Energy to establish a workflow and data capture system which allowed them to remotely process the data, including the incorporation of our highly-accurate GCPs (Ground Control Points) which are essential for data checking. The resulting outputs, including digital surface models (DTMs) and digital terrain models (DSMs) were used as part of the initial site assessment and validation.

Outcomes

Made efficiency savings by subcontracting data collection 

Established a strong B2B relationship ensuring high-quality deliverables

Our 24hr turnaround of outputs meant that data could be quickly processed

Enabled detailed maps and models at a lower cost for the end-user

Cost-saving, safety and efficiency benefits

Hours/days capture time*

Versus the traditional ground/roof based data capture time of weeks or even months for large assets, saving days / weeks

De-risking data capture

Versus ground or roof top inspections with ropes, scaffold and towers our aerial capture tools are “zero-touch”

Up to 80% cost saving

Versus traditional manual inspection costs by removing the expense of prolonged capture time, travel time and repeated in-person site visits

Fully digital remote inspection

Versus the traditional survey which does not “see” all of the asset from all aspects and elevations

Millions of data points

Versus ground/roof based surveys with limited access and finite resolution, allowing pinpoint accuracy across whole digital twin

3D interactive outputs

Versus the traditional 2D paper based reports and images which have limited access, coverage and quality

*For areas up to 10,000 or 1ha – roof inspection image capture in one day. Larger areas of up to 100ha are for landscape photogrammetry in one day.

Planning for high-quality drone mapping over large sites

Drone mapping is as much art as it is science. For large sites, it requires thorough planning to break the site down into manageable blocks that can be flown in 30-40 minutes. Google Earth Pro is used to create boundary files (kml) which are then uploaded to the drone for its automated flight. This includes a 50m site buffer. Positions are also established for GCPs with approximately 5 locations per block. On atypical day our team can fly up to 100 ha, and generate outputs to within a few cm accuracies over the entire site. We have used this approach for 1000’s of ha of sites, all over the UK, for Elgin Energy
