DNO Renewables
Commercial Solar

Grid connections for commercial solar installers.

From 50 kW rooftop to multi-megawatt ground-mount solar. Feasibility, G99 applications, G100 export limitation, connection strategy and offer review, delivered by engineers who work with commercial DNO teams every day.

Why commercial solar installers work with us

Commercial and industrial solar has DNO complexity that domestic G98 work doesn't. We deal with it every day.

Every commercial size handled

From 50 kW rooftop up to multi-megawatt ground-mount, plus every export limitation and G100 scheme in between.

HV and LV connections

We work across LV connections, HV service laterals and dedicated 11 kV connections. No project too complex.

Speak DNO fluently

Every engineer on our team has direct experience of UKPN, NGED, SSEN, SPEN, ENW and Northern Powergrid commercial teams.

The commercial solar DNO challenges we solve

Every commercial project runs into at least one of these. We handle the DNO side so your team stays on the install.

Common challenge

Client wants to know feasibility before committing budget

How we handle it

We run a feasibility check within 3 working days. Postcode-level DNO context, indicative capacity view, and a written go/no-go recommendation.

Common challenge

System size sits awkwardly between G99 and utility-scale connection offer

How we handle it

We advise on the optimum route, including whether export limitation gets you consented faster than an unlimited connection offer.

Common challenge

DNO comes back requesting extensive reinforcement

How we handle it

Independent review of the DNO's offer, plus negotiation on scope, timing and cost-apportionment where reasonable.

Common challenge

Multiple sites across different DNO regions

How we handle it

Single point of contact, standardised documentation, and portal-level visibility across every project regardless of DNO.
