Solar PPA for print works

Press-room cooling + drying ovens = consistent daytime kWh.

Typical system size	200–500kWp
Year-1 tariff	12–15 p/kWh
Best-fit structure	On-site PPA (sleeved for multi-site groups)

The press hall as a steady consumer

Commercial print is one of the more predictable electrical loads a solar system can serve. Litho and digital presses run long, planned shifts; the press room needs tight climate control, so chillers and air handling work continuously; and UV or infrared drying and curing stages pull hard whenever a job is on the machine. Add compressed-air plant and finishing lines and the result is a flat, daytime-heavy demand curve — the kind of profile that lets rooftop generation land squarely on live consumption.

Sizing and rate

Most print works occupy single-storey industrial sheds with generous, unshaded roofs, comfortably accommodating 200–500kWp. Contracted at around 12–15 p/kWh, generated units come in well under a typical grid tariff, and because so little is exported the saving is captured directly rather than leaking to the network. A quick pass through the consumption-based calculator will show where your own press schedule puts the number.

Energy cost you can quote against

Print runs on thin margins, and volatile electricity prices make estimating a job's true cost harder than it should be. A fixed or index-linked PPA rate turns an unpredictable overhead into a known input, so energy can be priced into a quotation with confidence for the length of the contract. That certainty often matters as much to a print MD as the headline saving — it is worth reading how a PPA rate is fixed or escalated before choosing a structure.

• Generation matched to two- or three-shift press patterns
• Rate mechanism chosen to stabilise job costing

If you are weighing the trade-offs, set a PPA beside an outright purchase to see which suits a margin-sensitive operation.

FAQs

Sector FAQs

What's the typical PPA tariff for a print work in 2026?

For print works, indicative 2026 tariffs are 12–15 p/kWh. Specifics depend on system size, off-taker covenant and DNO context.

What system size suits a typical print work?

Typical 2026 systems for print works range 200–500kWp. Larger sites suit the upper end of that range.

Why is this sector a good PPA fit?

Press-room cooling + drying ovens = consistent daytime kWh.
