Although gas turbine technology was the standard choice for power generation in Nigeria, Paras became increasingly interested in the advantages offered by Wärtsilä gas-fuelled engines, in particular their flexibility and ability to respond rapidly to load changes.
The steel melting shops use induction furnaces, and the variations in load requirements are significant. Furthermore, the Wärtsilä technology features low water consumption, an important consideration in view of Nigeria’s long dry seasons.
Eventually, Paras Group became convinced that the right choice for their three locations was the Wärtsilä 34SG gas engine. This has proven to be a wise decision.
In the years since the power plants were installed, not only has Paras Group's steel production been able to benefit from having a reliable source of electricity supply, but in 2016 Paras Energy began feeding Nigeria’s national grid, the first privately-owned company to do so.
Wärtsila 34SG engines in the three plants have a combined output of approximately 132 MW. Based on an average connected capacity of some 6.5 kW for each Nigerian home, this represents the annual consumption equivalent of close to 20,300 domestic household
The engines’ fast starting and stopping capability in response to existing supply and demand fluctuations as well as foreseen supply fluctuations from renewable sources, such as wind and solar, ensures that the plants are well in line with the Nigerian Federal Government’s integrated energy mix targets.
The Nigerian Sustainable Energy for All (SE4ALL) action agenda in the 30:30:30 vision document outlines a target of generating 30 GW of power by 2030, with 30 percent from renewable energy sources.
Moving forward in partnership with Wärtsila
Until early 2021, Paras Energy operated and maintained the plants themselves, but as its role as a national energy supplier has continued to increase, it was decided to take advantage of Wärtsilä’s experience in designing customised long-term service agreements to ensure the required high levels of plant availability, reliability, and efficiency. Having worked closely with Wärtsilä for 12 years, this was a natural next step in Paras Energy’s strategy for growth as the company seeks to play an even greater role in Nigeria’s energy sector.
By opting for a Wärtsilä Optimised maintenance agreement tailored to the specific operating requirements and needs of the customer, Paras Energy can be assured of their performance reliability. The agreement also provides maintenance cost predictability, which is an important consideration for budgeting purposes as the company grows. For its long-term service agreements, Wärtsilä utilises data-driven maintenance planning and scheduling procedures.
The core of the solution is continuous proactive support and recommendations from specialist advisers in Wärtsilä Expertise Centres, who help customers to optimise maintenance intervals according to actual needs. Their support prevents unexpected downtime and delivers guaranteed service levels along with the important cost predictability.
The agreement with Paras Energy effectively marries Wärtsilä’s world-class expertise and extensive experience with state-of-the-art digital technology.A key element within the agreement is the spare part planning process that ensures the ready availability of critical spare parts and, therefore, also the availability of the three plants.
The agreement runs for five years. Wärtsilä’s strong presence in Nigeria since 2006, with some 90 personnel employed, means that expert personnel are always on hand to support and assist Paras Energy as and when needed
