Commercial solar and renewable energy for Stokesley businesses

A small market town with a working industrial south end

Stokesley had 4,910 residents at the 2021 census, with the wider electoral ward at 6,180. It was granted a charter to hold fairs by Henry III in 1223 and still runs a Friday market on the High Street at TS9 5DQ, operated by Stokesley Town Council. Since 1 April 2023 the town has been governed by North Yorkshire Council, the unitary authority that replaced Hambleton District Council. The commercial base is small but more varied than the size suggests: independent retail and hospitality on the High Street, professional and veterinary practices, food manufacturing, engineering and light industry, and a large farming hinterland that fills the showground every September for the Stokesley Show, run by Stokesley Agricultural Society and drawing over 20,000 visitors and more than 130 trade stands.

What makes Stokesley unusual for a town of this size is how cleanly it divides. The Local Area Energy Plan case study prepared for York and North Yorkshire by Energy Systems Catapult describes a town split into two main areas, with the north predominantly domestic dwellings and the south predominantly commercial and industrial buildings, plus a smaller cluster of non-domestic buildings along the High Street. For anyone sizing a renewable energy project that split matters a great deal. The roofs with clear span, the three-phase supplies and the weekday daytime load are concentrated in one quarter of the town.

The commercial case starts with the bill. UK commercial electricity sits at 25 to 45p per kWh. A light industrial unit in Stokesley drawing 200,000 to 400,000 kWh a year is carrying an electricity cost that behaves like a fixed overhead and moves with the wholesale market rather than with your order book. Generating on site is the only lever that changes the unit rate you pay on the kWh you consume.

Matching technology to the buildings on Ellerbeck Way and Station Road

The industrial south of Stokesley is compact and easy to describe. Terry Dicken Industrial Estate runs off Ellerbeck Way, sat nav TS9 5JZ, with units numbered 1 to 15 and twelve occupiers listed by the estate itself, covering veterinary practice, cycle retail, technical materials manufacturing, ground investigation, office supplies and stove retail. The wider Terry Dicken Business Park extends along Ellerbeck Way, taking in Ellerbeck Court at TS9 5PT and Roseberry Court at TS9 5QT, where the estate's own rental office sits at number 6. Station Road carries the registered office and site of Marlow Foods Limited at TS9 7AB, company number 01752242, registered under SIC code 10890 for the manufacture of other food products. That is a genuinely mixed load profile in a very small area.

Both Station Road and Ellerbeck Way fall inside the Environment Agency's River Leven at Lower Stokesley flood warning area. That is a design constraint rather than a blocker, and it is one a national supplier working from a map will miss. Inverters, DC isolation, battery enclosures and switchgear on those streets should be mounted well above floor level rather than sat in a ground floor plant cupboard. The £3.7m Stokesley flood alleviation scheme completed in 2022 now better protects more than 509 homes and businesses using an upstream flow control structure, a re-profiled diversion channel and a downstream structure that stops Eller Beck backing up into the town, but the warning area designation still stands and your insurer will ask.

The right technology follows the building, not the brochure:

• Single-storey light industrial units on a weekday shift: rooftop solar first. At 5 to 6 m² per kWp, a 900 m² clear roof plane supports roughly 150 to 180 kWp.
• Refrigeration, compressed air or machining loads: a high steady daytime base load pushes self-consumption towards the top of the 55 to 85 per cent range before any battery is added.
• Trade counters, consulting rooms and veterinary units: arrays of 10 to 30 kWp paired with lighting, controls and heating upgrades usually beat a larger array.
• Older High Street premises: efficiency, controls and heat first, because roof area is limited and conservation designations complicate panel placement.
• Farm buildings on the edge of town: large uncluttered roofs, simple structures and far fewer constraints than anything inside the town centre.

North Yorkshire Council's carbon commitments and the planning backdrop

North Yorkshire County Council declared a climate emergency in July 2022. The council's Climate Change Strategy 2023 to 2030 commits the authority to achieve net zero in its own operational activity by 2030. That target covers the council's own estate, fleet, schools and street lighting rather than the businesses in it, so no Stokesley firm is compelled by it.

The number that reaches private premises is the regional one. The council's strategy mirrors York and North Yorkshire's Routemap to Carbon Negative, which targets carbon neutral by 2034 and carbon negative by 2040 for the region as a whole. A place-wide target of that kind cannot be met from public capital alone, and the Routemap says as much: delivery requires commitment from business and communities as well as public bodies. If you operate in TS9, you are part of the 2034 arithmetic whether or not anyone writes to you about it.

York and North Yorkshire Combined Authority has had a directly elected mayor since May 2024 and runs a £7m Net Zero Fund, split £6m capital and £1m revenue, allocated in October 2023. Be realistic about it. The published recipients were councils, the national park authority, education, community and faith organisations rather than private companies, so treat regional funds as something worth checking at the time you apply rather than a line in your business case.

On planning, the Hambleton Local Plan adopted on 22 February 2022 remains the adopted development plan for the Stokesley area under North Yorkshire Council, and its Policy RM6, Renewable and Low Carbon Energy, encourages renewable and low carbon energy installations. Rooftop solar on a commercial building is frequently permitted development, but listed status and conservation designations around the High Street change that position, and any ground-mounted scheme is a full planning application. The Local Area Energy Plan is also blunt about ground-mount around the town: land parcels close to Stokesley were discounted, mainly for flood susceptibility in the case of solar and proximity to buildings in the case of wind, with suitable sites tending to fall in neighbouring areas.

Grid capacity, Northern Powergrid and realistic G99 timescales

Northern Powergrid is the distribution network operator for Stokesley, and it is named as such in the town's own Local Area Energy Plan. Every commercial generation project here goes through them.

Any generation above 16 A per phase, which is roughly 3.68 kW single phase or about 11 kW across three phases, needs a G99 application and an agreed connection before it energises. Below that threshold a G98 notification after commissioning is sufficient. In practice every commercial array in Stokesley is a G99 job, and the application should start early rather than after the scaffolding is booked.

The practical reading for a Stokesley site is to keep the scheme at low voltage where you can. An export limitation scheme that caps what leaves the site will often hold a larger array inside an LV connection and inside the 18 week band, at the cost of some export revenue. On local headroom, the A1 Corridor Local Area Energy Plan places Stokesley in the East Cowton to Great Ayton zone and found that zone has spare capacity in the electrical distribution network, meaning it should be able to proceed with significant numbers of heat pump installations before encountering capacity constraints. It also recorded 3,636 dwellings in that zone, 40 per cent of the total, as off the gas grid, and expects most of its zones to see demand increases above 25 MW by 2040. Spare capacity today is not spare capacity in five years, so check Northern Powergrid's published generation availability map and open the conversation before you commit to a roof layout.

Northern Powergrid publishes its own guide prices and timescales, which is more useful than industry averages:

• Low voltage generation under G99: 45 day guaranteed standard for a quotation against a 45 day stated average, then an average of 18 weeks from payment to connection, at an average job cost of £20,300.
• High voltage generation under G99: 65 day quotation standard against a 67 day average, then an average of 12 months from payment to connection, at an average cost of £59,300.
• Extra high voltage: 65 day quotation standard against a 78 day average, and an average of 4.8 years from payment to connection.

Modelled scenario: 180 kWp on a light industrial unit off Ellerbeck Way

The following is a modelled scenario, not a real named client and not a project we are claiming. It uses the assumptions already set out on this page so you can see how the arithmetic behaves on a typical Ellerbeck Way industrial unit and test it against your own building.

The site is a single-storey light industrial unit with roughly 900 m² of usable roof on suitable planes, a three-phase supply, a single weekday shift and about 250,000 kWh of electricity a year bought at 27p.

At 5 m² per kWp the roof supports about 180 kWp. Against the 900 to 1,000 kWh per kWp range typical for this part of Yorkshire, that array generates roughly 165,000 kWh a year. With a weekday daytime load profile about 60 per cent is consumed on site, so 99,000 kWh displaces grid import at 27p and is worth about £26,700. The remaining 66,000 kWh exports at an assumed 5p under the Smart Export Guarantee, worth about £3,300. Year one benefit is therefore around £30,000.

At £900 per kWp, comfortably inside the £600 to £1,300 band, the installed cost is about £162,000, giving a simple payback of roughly 5.4 years before any tax relief. Adding around 100 kWh of battery storage at about £55,000 lifts self-consumption towards 75 per cent, moving roughly 25,000 kWh a year from a 5p export to a 27p avoided import. That is worth about £5,500 a year, a standalone payback near ten years, with the additional benefit of holding critical load through a short network interruption. A larger battery captures more of the summer surplus but does not shorten its own payback, because the extra capacity sits idle through the winter.

Every one of these figures moves with your consumption shape. A two-shift operation, on-site refrigeration or a cold store pushes self-consumption higher and payback shorter. A site that runs mostly at night does the opposite, and for that building the honest answer may be a smaller array with more storage, or storage and efficiency before any generation at all.

What projects cost here, and how Stokesley firms pay for them

On tax, the Annual Investment Allowance is the route to a full deduction in the year of spend, capped at £1m. A £162,000 array sits well inside it, and so does almost every project a Stokesley business is realistically going to run. This distinction is worth getting right, because solar is not main rate plant. HMRC's Capital Allowances Manual at CA22335 states that all capital expenditure on the provision of solar panels is specifically designated as special rate. Full Expensing is a main rate first-year allowance and does not deliver 100 per cent relief on solar; special rate assets attract the 50 per cent first-year allowance instead. If you want the full deduction in year one, claim AIA, and confirm the position with your accountant before you commit.

On export, the Smart Export Guarantee pays roughly 1 to 15p per kWh depending on supplier and tariff structure, so the export half of your business case is worth shopping rather than assuming.

On zero capital cost, the Stokesley Local Area Energy Plan itself identifies a power purchase agreement as the mechanism by which industrial and commercial buildings in the south of the town could take locally generated zero carbon electricity at reduced cost. Under a PPA the funder owns the equipment and you buy the output, so capital expenditure is nil, the saving per kWh is smaller, and the benefit starts on day one.

On grants, be careful with dates. The Workplace Charging Scheme covers up to £500 per socket, uprated from £350 on 1 April 2026, for up to 40 sockets across your sites, funded until 31 March 2027 and conditional on dedicated off-street parking. The EV infrastructure grant for staff and fleets closed to new applications on 31 March 2026, so do not build it into a plan. The Industrial Energy Transformation Fund, which funded energy intensive industrial processes and would once have been relevant to food manufacturing locally, closed in July 2025 and no successor fund is planned, so it cannot be built into a business case. The Public Sector Decarbonisation Scheme is restricted to public bodies.

One point of geography worth stating plainly. Stokesley has a Middlesbrough post town and a TS postcode, and many local firms supply into the Teesside industrial economy, but the Teesside Freeport tax sites are Wilton, Teesworks East and Teesworks West, all within Redcar and Cleveland. A TS9 site in North Yorkshire does not attract freeport capital allowances, and anyone telling you otherwise has read the postcode rather than the map.

Typical scale and payback across the technologies we install:

• Commercial solar: 30 kW to 2 MW, £25,000 to £1.5m, payback around 6 years.
• Battery storage: 30 kWh to 1 MWh, £20,000 to £500,000, around 7 years.
• Heat pumps: 30 kW to 1 MW thermal, £30,000 to £750,000, around 8 years, running at a COP of 3 to 4.
• EV charging: 7 kW to 350 kW, £3,000 to £150,000 and above, around 5 years.
• Energy management and efficiency: site-wide, £2,000 to £100,000, around 3 years, cutting 8 to 25 per cent of consumption.
• PPA and procurement: no capital outlay, equipment funder-owned.

A sensible order of work for a TS9 site

Renewable projects go wrong when they are bought in the wrong sequence. This is the order we work in, and it holds for a farm shed on the edge of town as well as for a unit on Ellerbeck Way.

Measure first. Pull twelve months of consumption and, where your meter supports it, half-hourly meter data, then find the waste. Efficiency measures cut 8 to 25 per cent of consumption with a one to four year payback, and every kWh you remove is a kWh you never have to generate, store or connect for. Sizing an array before this step usually means paying for capacity you did not need.

Generate second. Structural survey, roof plane and shading assessment, then the G99 application to Northern Powergrid. Allow 45 days for a low voltage quotation and around 18 weeks from payment to connection, and plan the works programme around that rather than the other way round.

Store third. Add storage once you know your genuine export volume rather than a modelled one. On the scenario above, a battery moved self-consumption from 60 to about 75 per cent and paid back on its own terms in about ten years.

Electrify fourth. Heat before vehicles, since an air source heat pump at a COP of 3 to 4 delivers three to four units of heat for every unit of electricity, then chargepoints. Doing both after generation and storage means the new electrical load is partly met by your own kit, and one grid application covers everything instead of three separate rounds of paperwork.

Fund last, once the shape of the project is settled. The choice is between capital purchase with AIA relief and a funder-owned PPA at zero capital cost, and it is a finance decision rather than a technical one.
