Jones and Reeves (1978) reported that a gasworks commenced operation by a Mr D. Davies in 1838, this may have been a small concern or an inaccurate date, as the town was not lit until 1859 as reported in the press “Illumination at Llanidloes on the Opening the Gasworks. For some time past the approaching introduction of the gas light into this town, has caused great expectation amongst the juvenile and poorer part of the population, many of whom had only hitherto heard of its brilliancy. Their anticipations were raised greatly on seeing during Friday and Saturday, the preparations proceeding in the town for a general light-up) by eight on Saturday evening, the streets were full of people, and a shout of delight arose from the crowd when the old Town Hall looking towards Long Bridge-street appeared one galaxy of stars.in the centre of which was seen this inscription, Llanidloes Gas Company, 1859, crowned with a locomotive engine, and below, a gas burner lighted. This transparency was surrounded with a wreath of evergreens. The whole tableau had a beautiful effect. The new Town Hall also blazed forth to the people that the gas light had now become an actual reality in their town for developed with a distinctness as bright as that given by the sun at noonday, appeared the words, Success to the town and trade of Llanidloes.", “The gas-works have been erected from plans prepared and under the superintendence of Mr. George Walcott, of Abchurch Lane, London. Competent judges have pronounced them equal if not superior to any of their size in Great Britain. The contract for the buildings, apparatus, and castings were carried out in satisfactory manner by Thomas Spittle, of Newport, during the last four months (The North Wales Chronicle, 12th November 1859). In 1867, it was reported that the gasworks were undergoing repairs and the town was without light (The Aberystwyth Observer, 1st June 1867). The Llanidloes Gas, Coal and Coke Co. Ltd. formed in 1858 and in 1859 the Company bought the business from Mr. Davies. In 1895 John D. Davies was Secretary and Thomas Munford the Manager, this was the same 1898, when the company had a capital of £2,500. In 1909 the Llanidloes Corporation, took advantage of the offer made by the Llanidloes Gas Company to supply tar free of cost for use on the roads, and began the work of improvement by filling up the holes, in the roadways with chippings and tar. They have now acted upon the suggestion made to tar the whole of the surface of the roads, which has proved a success (The Montgomeryshire Express 21st September 1909). In 1952 the “Gas World Year Book”, showed that Llanidloes was manufacturing 12 m cu.ft. of gas using horizontal retorts. H. J. Wright was the manager. The Llanidloes gasworks was connected to the Welshpool gasworks in 1959, which had a surplus gas supply. It was later supplied in 1960 through the Mid Wales Gas Grid from the Maelor gasworks at Wrexham, with the gasworks closing. 1961 A plan shows the old gas works between the River Severn and Victoria Avenue (Hafren Street). A new 50,000 cu.ft. holder had been built about 300 yards away and linked to the works by an 8" main. The new site was fed by the grid main from Newtown, which continued to Rhayader. The last gasholder was demolished in 1987-89, leaving just a regulator kiosk and a garage on site. The gasworks were visible on the 1879 to 1992 OS maps.
