OSPG is a company with a strong history in power generation services. It was started 20 years ago by myself as I gained expertise in generator set repair and maintenance. People came to me when they had a problem with a generator as they had great difficulty finding someone with both electrical and mechanical experience to help sort out issues with critical power generators. I gained a reputation for solving problems with diesel generators and making them operational again, which led to more and more calls for help. 1 year later, I left my full time position to set up Shanora Power Generators with a view to filling this area of expertise. Building on my skills and expertise I realised that there was a gap in the market and built my company, and became an exclusive sales and service agent for Mecc Alte in Rep. of Ireland.

“Great service for the past 16 years. Always our first choice.”

Paul - Area & Projects Manager, Petitts Supervalu

“Our first choice for PTO generators for the past 4 years. Great products and service.”

Mark - Sales Manager, Lisavaird Coop

“With a proven track record of 12 years we confidently recommend Tom O’Brien, OSPG Ltd as a reliable and competent partner for all diesel generator needs.”

Maurice Mythen, Mythen Construction


In 2005 I set up On Site Power Generation Ltd (OSPG Ltd) as a generator hire business working locally in Wexford which meant that I could better serve the needs of the market, the OSPG brand quickly gained a favourable reputation and shortly after I amalgamated Shanora Power into On Site Power, with all the business under the On Site Power Generation Ltd umbrella.

Since then the company has grown, as has our experience and expertise within the field of diesel electric power generation. We now serve as a one stop shop for power generation, we offer a full range of spares and power accessories, a wide selection of new and used diesel powered electrical generators, along with an extensive range of PTO driven generators for agricultural use.

We carry and stock a wide range of New and Used Diesel Generators, replacement Mecc Alte generators, control panels, AVR’s, Speed controllers, Actuators, Magnetic Pickup’s along with many other parts associated with power generation and diesel generator repair.

With great experience, personal service and quick and speedy response we are the people to call when you either need a new or used generator, hire power, or when your own generator is in need of repair.
