    Preface


    London is rarely considered an industrial centre. It has no coal mines, no great steelworks. And yet at the height of the Industrial Revolution between 1775 and 1800, apart from Lancashire with its vast cotton industry, the greatest concentration of Boulton & Watt steam engines was found in London. These engines kick-started the Industrial Revolution, and the presence of so many in London ably demonstrates the importance of the capital as an industrial centre. There were breweries by the score; the world’s first plastic material was synthesised in London’s East End, as was the first ever synthetic dye. After an extrovert Moravian demonstrated in Pall Mall that London’s streets could be lit by gas, gasworks were built throughout the capital. There were power stations, sulphuric acid works, the River Thames was full of colliers bringing coal from Newcastle, and London’s Docks were the envy of the world. Shipbuilding thrived on both sides of the Thames. Brunel’s Great Eastern was launched from the Isle of Dogs, and at the Thames Iron Works at Bow Creek the world’s first iron-hulled battleship, Warrior, was built. London was home to great engineers – Joseph Bramah invented his water closet and hydraulic pump, Henry Maudslay made machines to make machines, and John Rennie built his bridges. Motor cars, and even aeroplanes, were made. There were glassworks in Bankside, leather works in Bermondsey, and Royal Doulton pottery was crafted in Lambeth.

    Londoners had to be fed and food was imported to the capital’s markets – Smithfield, Billingsgate, Covent Garden, Spitalfields and Borough. There were (and are) food and drink manufacturers, and many household names began in London, such as Sainsbury’s, Schweppes and Crosse & Blackwell. Huguenot refugees fled to London after the revocation of the Edict of Nantes and dominated the silk industry of Spitalfields. The match girls at Bryant & May went down with phossy jaw, and East End immigrants worked in the sweated labour of the textile industry. The list is endless.

    For centuries men engaged in a common craft would combine together for their mutual benefit. Associations of this type were known as guilds and they dominated London’s trade and industry throughout the medieval period and beyond. By the end of the fourteenth century, guilds were empowered to control wages and prices and had the right to inspect all goods and confiscate them if found faulty. However, the Industrial Revolution of the late eighteenth century and the increasing demand for goods severely reduced the influence of guilds. Their power was based on the organisation of a close-knit community. Once industry became more diversely spread around the country, the power of the guilds waned. Many survive, but their role has changed. Today they sponsor charitable causes and educational bodies and get involved in good work, often associated with their former trade. It is with the period following the demise of city guilds that the content of this book is mainly concerned.

    As the book progressed I came to realise that more and more material could be included. The only sensible thing was to draw a line. Having said that, I appreciate that there are omissions and equally material has been included that should perhaps not be there.

    Thanks are due to the many people who have helped in my research – the staff at the British Library, and the local studies libraries at Tower Hamlets, Newham and Southwark. I would like to give special thanks to Southwark Local History Library, for it was there that my interest in the subject was born when I was given the chance to contribute to their local history of Bankside. Thanks are also due to John Greenwood without whose Industrial Archaeology and Industrial History of London: A Bibliography this book would not have been possible.

    1   The Electricity Industry


    Electricity Generation

    Michael Faraday’s parents came from Yorkshire. They moved to London, where his father, James, worked as a blacksmith in Newington Butts. It was here – the area now known as Elephant and Castle – that Michael Faraday was born in 1791. In 1796, the family moved to rooms over a coach house in Jacob’s Well Mews, Manchester Square. Faraday’s education was rudimentary and in his own words, ‘my hours out of school were passed at home and in the streets’. He was apprenticed to a bookbinder and his seven-year apprenticeship exposed him to books which he read avidly, most importantly those on science: ‘I loved to read the scientific books which were under my hands … I made such experiments in chemistry as could be defrayed in their expense by a few pence per week.’ In 1812, Faraday saved up sufficient money to attend the last four lectures that Sir Humphry Davy was giving at the Royal Institution. Faraday was entranced. He returned to the bookbinders, wrote up all the lectures and illustrated them with diagrams and sketches and bound them in a book which he sent to Davy, in effect asking for a job:

    My desire to escape from trade, which I thought vicious and selfish, and to enter into the service of science, which I had imagined made its pursuers amiable and liberal, induced me at last to take the bold and simple step of writing to Sir H. Davy expressing my wishes and a hope that, if an opportunity came in his way, he would favour my views: at the same time I sent the notes I had taken of his lectures.

    After a while Davy took him on to clean and dust his apparatus at 25s a week and he never looked back. At the Royal Institution, on 17 October 1831, Faraday generated a ‘wave of electricity’ by moving a bar magnet into a coil of wire. Thus he discovered electromagnetic induction, the means to generate electricity by converting kinetic energy to electrical energy.

    Due to the inadequacies of early dynamos, forty years elapsed before Faraday’s discovery could be exploited. It was the semi-literate but brilliant electrical engineer Zénobe Théophile Gramme who opened the way for electricity to be generated on a commercial basis. Gramme was born in Belgium and in 1871 he demonstrated his dynamo, with ring-mounted armature, at the Academy of Sciences in Paris. The Gramme machine gave a much smoother supply of direct current (d.c.) than had been possible hitherto.

    In its early days electricity was employed solely for lighting. The earliest form of lighting was the arc lamp. Humphry Davy, at the Royal Institution, had discovered the arc lamp in 1808. He allowed current (generated by electrolysis) to jump between carbon electrodes thereby producing a brilliant light. But early arc lamps had a short lifespan and were unreliable. It was not until the Russian telegraph engineer Paul Jablochkoff, working in Paris in 1876, invented the Jablochkoff Candle that arc lamps became a practical possibility. Jablochkoff’s lamp consisted of two carbons rods separated by a paste of kaolin. When a current flowed, carbon paste between the two electrodes burned away emitting a dazzling light.

    Given that both Gramme and Jablochkoff were working in France, it is hardly surprising that the French took the lead in installing electrically powered public lighting. In July 1878, the journal The Electrician highlighted the lack of progress in England, complaining, ‘in London there is not one such light to be seen’. Yet within one month things were to change.

    The first public building to be lit by the new electric light was the Gaiety Theatre, where arc lamps were installed in August 1878, described as ‘half a dozen harvest moons shining at once in the Strand’. Then, a couple of months later, the French company Société Générale d’Électricité began an ambitious programme of street lighting along the Victoria Embankment between Westminster and Waterloo Bridges. Their power station – if that is the most appropriate way to describe it – was situated on the opposite side of the river, west of Charing Cross Bridge. It consisted of a wooden shed containing a steam engine, operating at 60psi pressure and driving a Gramme dynamo at 650rpm. Power lines ran beneath the Thames via a subway to power twenty Jablochkoff lamps on the north bank. More lamps were installed later, including some on Waterloo Bridge, but then, in 1884, the Jablochkoff Company went into liquidation and gas lights were reinstated.

    Meanwhile, another scheme was under way at Holborn Viaduct. Sixteen Jablochkoff lamps were installed over a 500yd stretch of the viaduct and powered in a similar way to the Victoria Embankment scheme. The Times newspaper of 16 December 1878 reported:

    On Saturday evening the electric light was experimentally tried upon the Holborn Viaduct, at the instance of the City Commission of Sewers [and] the light was remarkably steady and brilliant. The trial will be continued for some time and arrangements are being made for it to light the Royal Exchange and the Mansion House.

    The trial was, however, less than successful and Colonel Haywood, engineer to the City Commission of Sewers, was reported in The Times of 21 March 1879 as ‘estimating the cost to be seven times that of gas and that the commission have resolved not to continue the experiment’. And that would appear to be that!

    The gas companies were jubilant, boasting that ‘we are quite satisfied that the electric light can never be applied indoors without the production of an offensive smell which undoubtedly causes headaches and in its naked state it can never be used in a room of even a large size without damage to sight’. The problem lay with the intensity and dazzling light of arc lamps, and the fact that they smelled and emitted a hissing noise. But the gas companies had not bargained with the pioneering work of Thomas Edison and Joseph Swan.

    Joseph Swan was born in Sunderland in 1828. Having trained and set up in business as a pharmacist, he began experimenting with incandescent lamps in the mid-nineteenth century but was hampered because he could not obtain a good vacuum in his bulbs. Vacuum pump technology improved later in the century and, in 1875, he was successful in making an incandescent lamp with a carbonised thread as filament. He patented his bulb in 1878, just before Thomas Edison in America did just the same. The two men joined forces and the Edison & Swan Electric Light Company was founded. By not having to rely on arc lamps, electric light now became a practical possibility.

    Thomas Edison was quick to exploit the new electric light. In January 1882, he got in touch with the City Corporation and proposed that the Holborn Viaduct scheme be revisited. Edison offered to light the viaduct free of charge for three months and also to supply private consumers. The Times of 13 April 1882 reported:

    From Newgate Street westward, across Holborn Viaduct, to Hatton Garden, the street and most of the buildings on either side of the street are now and for the next three months, will continue to be lit by Edison incandescent lamps. For the purpose of street lighting two of the incandescent lamps of 32 candle power each have been placed in every lamp-post and it had been hoped that last night permission would have been obtained from Colonel Heywood [sic] for the gas to be turned out in order that the effectiveness … might be proved the more satisfactorily … it is hoped that tonight the public will be able to judge on the matter themselves. Those that can obtain permission to see the machinery and appliances by which the electricity is generated and distributed will find a satisfactory answer.

    The machinery The Times spoke of was sited at 57 Holborn viaduct (on the north side of the road) and can claim to be the first power station in the world. Current at 100V d.c. was supplied from an Edison dynamo driven by a steam engine, with steam raised from a water tube Babcock & Wilcox boiler. One thousand Edison lamps of 16cp each were installed; later, a further 1,200 were powered from another generator at 35 Snow Hill. Along the route was the City Temple, which can lay claim to being the first church to be lit by electricity. The mains were copper conductors, encased in insulation within wrought-iron pipes. Holborn Viaduct Power Station continued to operate until 1886.

    A Myriad of Small Stations

    In the early 1880s, the Great Western Railway built a power station to light Paddington Station, its offices and the Great Western Hotel. According to The Electrician, it supplied ‘by far the largest installation of mixed lighting hitherto made’. The power station stood a quarter of a mile from Paddington Station on the south side of the track. There were three 350kW alternators housed in a wooden building with double walls, so constructed to keep the noise down. It plainly did not, because in 1885 the residents of nearby Gloucester Terrace complained to the magistrates at Marylebone Police Court that the ‘tremendous vibration and noise, added to the fumes of smoke and steam and dirt caused by the machinery, produced such a nuisance as to be almost unbearable’.

    Meanwhile, in 1887, the Cadogan Electric Lighting Co. installed a series of storage batteries in the houses of residents in Chelsea, South Kensington and Knightsbridge, and, via overhead transmission lines strung from poles, supplied direct current from a small power station in Manor Street (now Chesil Court) next to Albert Bridge. The scheme did not prosper; by 1895, only twenty-five houses were being supplied. The Cadogan Co. was then taken over by the Chelsea Electricity Supply Co. which had obtained consent to lay mains beneath the street. Their power station, in the basement of a house in Draycott Place/Cadogan Gardens, supplied direct current to batteries in a series of substations, one at Draycott Place, the others at Pavilion Road and Egerton Gardens Mews. The substations were charged in series and supplied low tension d.c. to customers in parallel. Another power station was built in 1894 at Flood Street, and by 1911 the company’s capacity had increased to 3,400kW, with further substations at Elm Park Gardens, Clabon Mews and Pond Place. The Chelsea Co. ceased generating in 1928.

    The Whitehall Electric Supply Co. was formed in 1887 with the intention of lighting Whitehall Court (now the Royal Horseguards Hotel). A power station was built in front, underneath the road, and its customers included the church of St Martin in the Fields and various premises in Northumberland Avenue. Within the year it was taken over for £40,000 by the Metropolitan Electric Supply Co., which soon purchased a small power station in Rathbone Place, off Oxford Street. The Whitehall Court scheme supplied direct current, but at Rathbone Place the company opted for alternating current (a.c.). Another power station was constructed in Sardinia Street at the south-west corner of Lincoln’s Inn Fields, and the Metropolitan Electric Supply Co. now served Marylebone, Bloomsbury, Lincoln’s Inn and Covent Garden. A further station was built at Manchester Square in 1890. However, because of complaints – houses vibrated and clocks stopped – an injunction was served on the company. It was on the point of shutting down but the day was saved by replacing the noisy reciprocating Willans engines with three 350kW Parsons turbo-alternators, the first to be installed in the capital.

    An early generating station was built, just south of Kensington High Street, by R.E. Crompton & Co. to illuminate Kensington Court. By 1890, the Kensington Court Electric Light Co. was supplying d.c. to the surrounding area. It was soon acquired by the Kensington & Knightsbridge Electric Lighting Co., which had a power station in Cheval Place. In 1892, 645kW was generated at Kensington Court and 410kW at Cheval Place.

    The Westminster Electric Supply Corporation had two plants in 1890: one at Stoneyard, Millbank, near the House of Lords, supplying the Palace of Westminster; and the other at Chapel Mews, near St James’s Park Station. They had further stations, all d.c., in Dacre Street, in Eccleston Place to supply Belgravia, and Davies Street to supply Mayfair. In 1904, a substation was built at Duke Street, Mayfair, and in 1910 the Millbank plant was demolished to make way for Victoria Tower Gardens. Meanwhile, a new station was built in Horseferry Road, near Lambeth Bridge.

    The St James’s and Pall Mall Electric Lighting Co. built their first power station in Mason’s Yard, Duke Street. Sited in the heart of St James’s, the station was prone to pollute the surrounding area with an oily spray which did nothing to please the members of London’s fashionable gentlemen’s clubs. As one of the engineers commented,‘it was almost a daily occurrence to see a gesticulating man pointing out his damaged top hat’. Wyndham’s Club even obtained an injunction against the plant but then had the nerve to insist that their supply shouldn’t be cut off! The company laid its mains in cast-iron culverts and on one occasion the outer casing became live. An old and unsuspecting horse was unfortunate enough to place his iron-clad hoof on the casing and received a fatal shock. The owner was compensated with £40 but soon afterwards a similar accident happened to a horse drawing a hansom cab. From then on it was commonplace for cab drivers to pass along Jermyn Street with old and worn-out nags in the hope that a similar fate might befall them. In 1893, a new station was constructed in Carnaby Street and by the end of the century the company amalgamated with the Westminster Company and began to build a new plant at Grove Road.

    The Charing Cross Electricity Supply Co. traced its roots back to a small power plant installed in 1883 in the basement of the Adelaide Restaurant in the Strand owned by the Gatti Brothers. Two years later Messrs Gatti were supplying the Adelphi Theatre and in 1888 built a new station in Bull Inn Court, between Maiden Lane and the Strand. Acquired by the Charing Cross Co. in 1889, the new company soon expanded south of the river and built a plant between Waterloo and Blackfriars Bridges. In the early twentieth century consent was obtained to supply the City from a new power station at Bow. By 1919, its capacity was 74MW.

    Originally known as the House-to-House Electric Light Supply Co., the Brompton & Kensington Electricity Supply Co. had an a.c. power station in Richmond Road, Brompton, in 1889. To begin with, every customer had a transformer in their own home before the company installed a series of their own transformers to supply low voltage. In 1928, when they finally ceased generation, the plant had a capacity of 8MW.

    The County of London Electric Lighting Co. ran two power stations: one at the City Road basin of the Regent’s Canal; the other on the banks of the Thames at Wandsworth. They began operation in 1896.

    The first local authority to supply electricity in London was St Pancras. A power station was built in Stanhope Street, just to the east of Regent’s Park. A second station opened in King’s Road and was unique in that it used the hot gases from a refuse destructor to heat its boilers – an early example of energy conservation. Hampstead opened a small station on Finchley Road in 1893, to be followed by Islington which built a generating plant at Eden Grove, off Holloway Road. Ealing was soon to follow the example of St Pancras and harness heat from a waste destructor plant, and Shoreditch followed suit with a plant in Coronet Street, opened by Lord Kelvin in 1897. It came in for much criticism and was labelled a waste of time, but the chairman of the Shoreditch company insisted in a letter to the technical press: ‘We are absolutely raising from our ashbin refuse sufficient steam to drive our electrical plant, giving a maximum output at our heavy load of 250kW, and this we are raising solely from ashbin refuse.’

    Towards an Integrated Supply

    So why did the electricity supply industry develop in such a haphazard way in London, and everywhere else for that matter? The answer is found in the early legislation to which the industry was subject. A select committee was established to look into the matter, chaired by Sir Lyon Playfair in 1879, and set the seal on how the industry was to develop for at least the next forty years. The committee recommended that electricity undertakings should supply power only within the area under the jurisdiction of their particular municipal authority. The result was scores of small power stations, each supplying only a small area.

    The recommendations were given the authority of law by Joseph Chamberlain’s Electric Lighting Act, which received its royal assent in 1882. The Act sought to prevent monopolies and also favoured electricity supply being put in the hands of municipal authorities by empowering them to compulsorily purchase private undertakings after a period of, first, twenty-one years and then (by the terms of a later Act) forty-two years. There were thus conflicting interests between local authorities and private concerns. The Electric Lighting Act of 1909 went some way to improve matters by allowing the Board of Trade powers (over the heads of local authorities) to authorise the breaking-up of streets and the compulsory purchase of land for building power stations.

    The early legislation of the electricity supply industry has come in for much subsequent criticism – often laid at the hands of Joseph Chamberlain – whose horror of monopolies, and tenure as mayor of the thriving industrial city of Birmingham, no doubt influenced his preference for supply being provided by municipal authorities. But it was not only legislation that caused confusion – there were technical matters as well. These centred on whether it was preferable to supply direct current or alternating current. The controversy became known as the ‘battle of the systems’, with eminent men in both camps. Ferranti was a fervent advocate of a.c., whereas R.E. Crompton and indeed Thomas Edison favoured d.c. Alternating current supply eventually won the day because of its ability to transmit high voltages from large power stations over large areas without power loss. But in the early days of power generation d.c. offered many advantages. The most important of these was that it ensured security of supply because batteries could be used as a stand-by supply in the eventuality of plant breakdown. In contrast, if an a.c. generator broke down, the lights went out at once – a common occurrence which did much to enhance the cause of d.c. supply. It is little surprise, therefore, that the great majority of early power stations generated direct current – only the London Electric Supply Co. and the Metropolitan Electric Supply Co. favoured alternating current. But gradually advances in engineering – particularly the replacement of belt-driven generators by the turbo-alternator – began to favour large-scale a.c. transmission.

    But there was still a multitude of different companies: in 1921, there were eighty separate supply concerns in London, supplying power from seventy different power stations, with fifty systems of supply, twenty-four voltages and ten frequencies. Looking at it from the customers’ point of view, it meant that moving home meant changing all one’s electrical appliances! And from the suppliers’ viewpoint, because the stations were not interconnected each company was forced to install excessive reserve plant to cover for breakdown, or outage due to essential maintenance. The net result was that electricity was expensive!

    The government responded later in the 1920s by setting up a committee under Lord Weir to enquire into the industry and make recommendations. Reporting in 1925, Weir recommended a national ‘gridiron’ of high voltage transmission lines taking power from the most efficient ‘selected’ power stations. His recommendations became the basis for the Electricity Supply Act of 1926. Selected stations – still either in private hands or owned by municipal authorities – generated alternating current at a standard frequency and sold it to the newly formed Central Electricity Board (CEB). Each company then repurchased electricity from the grid at a price not greater than it would have cost them to produce had the grid not been in operation. They then supplied their own customers in the same way as before. The CEB had the job of selecting stations and forcing inefficient undertakings to close their power plant and purchase supply from the grid. For the consumer, the result was a halving in the price of electricity.

    The Second World War curtailed the construction of new power plant and, combined with a shortage of coal, power cuts after the war were inevitable. The building of new and large efficient power stations commenced immediately after the war. In London a new Bankside station was begun.

    The post-war Attlee government nationalised the industry and by the terms of the Electricity Act of 1947 the British Electricity Authority was formed, later to be replaced by the Central Electricity Board and then the Central Electricity Generating Board (CEGB) in 1958. The CEGB ran all power stations in England and Wales and sold power to twelve area boards; in London this was the London Electricity Board (LEB). In the early 1990s, the industry was privatised but by that time all London’s power stations had shut down and supply was taken from more efficient stations elsewhere.

    Famous Thames-side Power Stations

    Deptford Power Station – Ferranti’s Dream

    The story of Deptford Power Station starts in the most unlikely of places – New Bond Street in London’s fashionable West End. There, in the mid-1880s, Sir Coutts Lindsay and Lord Wantage put up the money to illuminate the Grosvenor Gallery by means of a steam engine driving two Siemens alternators generating current at 200V. So impressed were local shopkeepers and residents that they asked to be connected to the system. Accordingly, overhead lines were strung along iron poles from house to house and transformers installed in each property to reduce the voltage. Rather than installing meters, each consumer paid £1 per year for every 10cp lamp and £2 for every 20cp one.

    As with all new ventures, problems arose and so the young and ambitious Sebastian Ziani de Ferranti was called in to solve them. Ferranti was descended from a noble Italian family and was educated at St Augustine’s Roman Catholic College in Ramsgate. After the briefest apprenticeship at Siemens, he set up in business at the tender age of 18 with the engineer Alfred Thompson and the lawyer Francis Ince. Ferranti immediately set to work to update the Grosvenor Gallery station by replacing the Siemens alternators with ones of his own. But Ferranti and his backers had other, more ambitious, schemes in mind. A new company was set up, the London Electric Supply Corporation (LESCo), with an authorised capital of £1 million in shares of £5 each.

    Ferranti’s dream was to supply large areas of London from what was, by the standards of the day, a giant power station situated by the river. There would therefore be an ample supply of cooling water, and coal could be delivered at minimum cost by sea from the coalfields in South Wales or Tyneside. He took his lead from the example of the gas companies, such as the Gas Light and Coke Co. which had consolidated their works at the remote site of Beckton. To quote Ferranti:

    The business of distributing electrical energy must be done on a large scale to be commercial, and to attain this we must supply a large area … and we must do this from a site not in the congested heart of a big city but from a position best suited by its natural advantages to the carrying on of such an undertaking.

    The site chosen was Deptford and LESCo set about building their station on land just to the west of Deptford Creek on a 3-acre site called the Stowage, previously used by the East India Company. Initial plans were for four 10,000hp engines, powered by steam from eighty boilers, driving four alternators supplying current at the then unheard of voltage of 10,000V.

    Ferranti was newly married, but the building of Deptford Power Station was still at the forefront of his mind – he would often stay all night at the plant. His wife was to write later: ‘The first thing I remember during those first months of married life was Deptford, and again Deptford. We talked Deptford and dreamed Deptford.’ Ferranti’s obsession did not go unnoticed: the journal The Electrical Engineer called him the ‘Michelangelo of that installation because from first to last, from foundation to highest turret … all were specified or designed by one man, and the credit of that success will have to be given … to Ferranti’.

    The first transmission cables from Deptford to supply London proved inadequate and so Ferranti, true to his character, set about designing and manufacturing them for himself. Rather than dig up streets and lay the cables underground, he came to an arrangement with the local railway companies and laid his cables along the railway track running from Deptford into London via Cannon Street, Blackfriars and Charing Cross railway bridges. He came to a similar agreement with the Metropolitan & District Underground Railway.

    But the Board of Trade concluded that four 10,000hp engines in one location at Deptford would be a risk to the continuity of supply should there be a breakdown. The Board was also keen to ensure competition and recommended both a.c. and d.c. distribution. The consequence was that Deptford’s area of supply was halved. In response, LESCo modified their plans and installed twenty-four Babcock & Wilcox boilers, producing 414,000lb of steam per hour driving two 1,250hp Corliss steam engines connected from fly wheel to the alternators. Then, on 15 November 1890, disaster struck at Grosvenor Gallery. Due to operator error, a momentary 5,000V arc was allowed to start a serious fire which eventually shut down the entire station. Supply was curtailed for three months and, not surprisingly, many customers transferred their allegiance elsewhere. LESCo lost money and many were quick to point the finger at Ferranti’s wild scheme. The company was forced to cancel its order for the 10,000hp machines and in August 1891, Ferranti left Deptford. However, as we have said, his vision of large power stations supplying large areas of population was to be realised – but much later.

    Electricity continued to be supplied from Deptford. In 1904, two 2MW alternators were
