Put simply, "Yes". If you applied for a £4k grant which has been approved, and the works the contractor completed match the application (i.e. they did actually change the relay, not just update the settings in the old one) it is irrelevant what the contractor charged you, you still invoice the...

Hi Farmerfred Yes and no really. G59 has now changed to G99 for brand new connections. This upgrade program is a G59 upgrade program so your solar site will become G59/3-7 compliant rather than G99 compliant. This is generally recommended as a site is not G99 compliant simply by changing the G59...

Hi I will be able to help you if you require. I can run you through why you will or won’t need to complete any upgrade works and how we can work this out. WindCare is a recognised contractor with all the DNOs to complete these works and have completed hundreds across the country - with no cost...

Hi Lazy Farmer. Happy to help if you need us. Most likely no works will need doing on your solar site, but worth checking nonetheless whilst grants are available and someone else is paying for the works. If you want to email me your details I can get in touch to discuss your site...

Hi All. I run the ALoMCP for WindCare - we are a recognised contractor with all the DNOs and have completed these upgrade works on over 300 sites across the country and across plenty of different technologies - wind, solar, AD/CHP, biogas, Battery etc It certainly can be a confusing subject...

Hi All, Windows 5 & 6 are now open. Any renewable generator that hasn't done this upgrade please get in contact for assitance. It is a mandatory thing, and currently the grants cover all the costs. There is no advantage to wait - the advice from the DNOs is "although this confirms dates for...

Hi Bob Enercon wind turbines with Siemens relays installed definitely DO need this upgrade work completing- see extract taken below from Northern Power Grid's Letter they send out (all the other DNOs work from the same info). They don't need a new relay installing, but the settings do need...

Anyone that is still needing the G59 Upgrade completing (i.e. anyone with a renewable generator and G59 relay installed before February 2018), the last official window for the grants closes on 11th August. The application is not a long and demanding process once we have the information, and we...

Sorry, I didn't get a notification of these messages. Solar inverters don't have loss of mains protection per se (i.e. Vector Shift or RoCoF), but they still have Under/Over Voltage and Frequency settings. So if there is no 'Mains' then they trip out on Voltage or Frequency still. This is why we...

Hi Dave, if Mainspro are now offering a 'bench tested' relays just be a bit careful with this, as you still need to complete the dynamic testing on site (i.e. prove it works when fitted in your installation) after you've fitted it which forms part of the G59 commissioning checklist you need to...

Hi Matthew - Yes, Exfarmer is about right! Any that use the inverters for G59 protection don't need upgrading (99.99% of the time - there are weird/wonderful inverter manufacturers that might need looking at, but these are very rare and we've not come across them - there is a list on the ENA...

Hi there. That is a strange one! There may well be a very specific reason for this, but we have done several hundred applications, and if the site has a G59 relay installed before February 2018 then it is fairly cut and dry and I haven't come across any that are exempt. I would recommend you...

Hi. If you can only get a grant for disabling, you can still change the relay, but can only apply for the disablement grant. Prior to February this year you could get paid for a relay replacement, but they reduced the grants from 1st February for wind/solar. Disabling the LoM is quite fine for...

Hi. Yes the 11th August 2020 is currently when the grants run out - see image attached. They may extend this, but no confirmation yet In terms of replacing relays, there are individual cases/relays, but generally wind/solar (unless DFIG wind which tends to be big wind) only qualify for a LoM...

Hi Bob Yes, you can upgrade this relay by disabling the LoM settings from within it. The Siemens relays in the Enercons we have done have all have very low RoCoF settings which are the worst offenders as far as National Grid are concerned. We can check these settings on the relay itself or if...

Hi @Bob - if you have a G59 relay on renewable energy installed before Feb 2018 it will need upgrading. It’s not about your existing one being broken or not working, it’s new regulations that National Grid have brought in that mean your existing relay needs upgrading. Have a look on the ENA...

Hi All, Some of you will already be aware, but National Grid have brought out new regulations that mandate all G59 relays installed before February 2018 need upgrading – this includes solar, AD, wind turbines, CHP, hydro etc – called the Accelerated Loss of Mains Change Program. The program is...

All guys There are other companies that complete this work. WindCare have completed plenty of these upgrades and provide competitive O&M service and Maintenance works on hundreds of turbines across the country. 01751472595. www.windcare.co.uk

Hi All, I work for a company called WindCare. We are a contractor completing G59 upgrade works on several hundred sites across the country on solar, wind, AD, CHP, batteries etc. If any of you still require some help with this G59 upgrade program please contact me: 0789 1938955 -...
