2018 - The extant generating buildings are seen here in 2018, having been re-roofed as per the original, retaining the skylights that were opened via pulleys to keep the generating machinery cool. Much work is needed to conserve this valuable heritage asset, which, at the time of writing in July 2022, has no reasonable or beneficial use, such as to generate an income for maintenance and restorations. This is a prerequisite for any conservation project, with the duty to act to conserve the historic built environment laid fairly and squarely at the door of the local authority. The building is thus vulnerable, at risk, and in need of protection. According to a Report from 1999, one range is missing in this picture, now partly re-instated.





Lime Park Heritage Trust (LPHT) is a charity that exists to protect, restore and conserve what is considered to be a unique surviving example of technology employed from 1900 to 1936, that is newly recognised as the cornerstone of renewable technology, in the fight against climate change: load levelling.


The Trust came into being many years ago before 2005, now with six trustees in 2022, and renewed impetus as a result of the potentially cataclysmic effect of global warming on planet earth as a whole.




1. Administration 

The charitable trust created by this deed (‘the charity’) shall be administered by the trustees. (In this deed, the expression ‘the trustees’ refers to the individuals who are the trustees of the charity at any given time. It includes the first trustees and their successors. The word ‘trustee’ is used to refer to any one of the Trustees.) 

2. Name 

The charity shall be called 


3. Objects 

The objects of the charity (‘the objects’) are: 

As the long-term occupiers of what is presently known as ‘The Old Steam House,’ in actuality the early electricity generating buildings dating from between Circa 1890 and 1909, situated, in Lime Park in the Parish of Herstmonceux, East Sussex, BN27 1RF, United Kingdom, to take all reasonable steps to protect, conserve, maintain and where applicable, carry out necessary restoration works and repairs to the monument, with reference to a Report from Archaeology South East, Institute of Archaeology, University College London, dating from 30th September 1999, Project Reference: 1146, centred at TQ 635 1223 (David & Barbara Martin).


In furtherance of these objects, to manage the property, to obtain a reasonable and beneficial use, such as to (insofar as possible) generate an income for the upkeep of the grounds, fences, grass, hedge cutting, and to settle bills for heating, lighting and other necessary services, in support of the historic Monument, once part of a Monument Protection Programme (MMP), as part of a Monuments At Risk register (MARS) with reference to English Heritage Electric Power unusual wooden architecture 5th May 1999, and Step 4 Report inclusion, June 2000 (Jill Chitty). This document superseding all previous Lime Park Heritage Trust documents. 





HERSTMONCEUX 1911 - Charles de Roemer was a mover and shaker at the turn of the century, over 120 years ago, when he installed a small building on his estate, to provide electricity for his manor house in Lime Park. Some years later, by 1909, he expanded his generating works with a battery store, coal bunker and gas producing plant, to provide electricity under a field using cables, to the village, where in 1913 he was giving cooking demonstrations in the village hall, using electricity.




When it comes to recognising and assessing more recent industrial archeology, that as is understandably the case, that Historic England, formerly English Heritage, is some distance behind the curve. Rather than predictive.


This is mainly because developing technology, that which has been recently improved on, or with the realization that technology employed in days gone but that was thought to be an oddity, is in fact vital to the future of electrification in an age transitioning to renewable energy, from fossil fuels.







COMPETITORS & EVENTUAL PARTNERS - It is painful to cast aspersions on the reputation of one of America's heroes, but Thomas Edison, who patented his bulb in 1879, improved on a design that British inventor Joseph Swan had patented 10 years earlier. Improvement patents, are however, still significant inventive steps and legitimate development, and Edison made filament lamps more practical, by increasing the resistance, to overcome the huge currents that would otherwise have been needed to yield light.




One cannot expect an archaeologist with formal training, to keep up with current trends, or future needs.

This heritage asset at Herstmonceux remains extant (at present culturally unprotected) as evidence of human endeavour, hence could be a UNESCO world heritage site at some time in the future. We understand that Lime Park Heritage Trust, is doing its utmost, in difficult circumstances, to protect this unique find. It would be a shame to lose it. Once it's gone, it's gone.








SWITCHES & BULBS - Where would we be without electric lighting. A battle royal ensued in the law courts and Thomas Edison and Joseph Swan slogged it out in the London High Court, ending with the combatants working together as the Edison & Swan United Electric Light Co. ELECTRIC BAKERY - The earliest surviving generating station, dating from C. 1900, with battery based load levelling as the core technology, coupled to a 48 volt DC generator, is in the little village of Herstmonceux, Sussex.







MAY 2012 - Following an epic legal and planning battle, that lasted from 1981 until 2017, before entering a cold-war stage, and is still the subject of long overdue data corrections, this is what the generating buildings looked like about ten years ago. All the while local politicians and planning civil servants played down the importance of preserving archaeological evidence, these important remains, evidence of the coming of the age of electricity, were virtually derelict, hardly appealing to the eye or historians as a time capsule, of a bygone age. It was just lucky that during World War Two, Charles de Roemer and others in Lime Park, had covered the original timber buildings in corrugated iron as protection from bombing raids. It is thought that this covering helped to preserve the wooden frame and match-boarding. Mr de Roemer also installed a concrete bomb shelter, built into a hillside, as part of his preparations during hostilities - no doubt using his experience in the Royal Field Artillery and Air Force, to make sure that his beloved electrical enterprise remained.




Electricity grids are key to renewable energy distribution



The electrical power generation industry began when light bulbs and other devices that needed reliable energy supplies were invented. Telephones and televisions all needed electricity.
