Power System Studies

Power system studies ensure the safe, efficient and reliable operation of electrical networks that are essential to business. Reduced downtime and continuity of supply will save you time and money.

Power Quality Surveys

If you’ve observed an increase in power quality issues, experienced a system failure or simply need a routine system health check, then a detailed Power Quality Survey is essential if you want to establish what’s happening in your electrical network.

Renewable Energy Consultancy

At a time when the UK is playing a leading role in the global drive to achieve Net Zero, Enspec is responding to the challenge with a full consultancy and facilitation service for large energy users to improve productivity and sustainability.

Power Factor Correction

Power Factor Correction (PFC) is an energy saving technology. Through improved energy efficiency, PFC can significantly reduce electricity costs by eliminating Reactive Power Charges, reduce network I2R losses and even free-up available power for plant expansion.

Harmonic Filters

Harmonic filters improve the quality of your power supply. Nuisance circuit breaker tripping, stresses on electrical plant and downtime can be reduced to save you time and money.

Reactive Compensation

Reactive compensation provides any shortfall in reactive capability that is a crucial part of grid code compliance. Obtaining a grid connection agreement is essential to exporting electricity and generating income.

Point-on-Wave Switching

Point-on-Wave (P-o-W) switching prevents high inrush currents commonly associated with the mechanical switching of transformers, reactors and capacitors. It offers a cost-effective and compact electronic solution to switching transients and can be installed at initial build stage or as a retrofit to existing circuit breakers.

Site Services

Site services such as preventive maintenance provide operational peace of mind and increase profitability through reduced downtime. A wise old engineer once said, "If you don't schedule time for maintenance, your equipment will schedule it for you!"

"Vestas Wind Systems have developed a great collaboration with Enspec over the last 15 years on Wind Power Plants across the world. Vestas is thankful to Enspec for their excellent in-house engineering skills, their ability to quickly bring innovative technologies to market and their great customer service. We are sure this excellent relationship will continue for the years to come."

Michail Theodoridis, Lead Electrical Engineer, Vestas

"Powersystems UK engaged Enspec to provide a SynchroTeq for Aikengall II Wind Farm, their engineers were very helpful with reviewing the wiring diagrams and also provided great support on-site throughout the commissioning. The SynchroTeq reduced the 132kV voltage dip to 0.6% from a predicted 18%. Powersystems see the SynchroTeq as a great option for mitigating inrush current, even on large grid-scale transformers."

"Banks Group have two innovative Enspec Point-on-Wave switched capacitor banks installed at our Kype Muir wind farm. Following a request Enspec adapted their installation to include de-tuning reactors to manage harmonics. I have appreciated working with Enspec, they have been innovative, flexible and responsive."

Dan Thomas, Operations and Grid Director, Banks Group

"Vizimax is thrilled to partner with Enspec Power, whose expertise, know-how and technical resources really help clients get the most of our technologies in the field. Their unique mix of advanced engineering, from simulation capabilities to creative problem-solving approaches, of high-quality, durable integrations, and of top-tier commissioning services, hands-down qualify Enspec Power among the most efficient and trustable Vizimax solution specialists for any HV and MV switching project"

Laurent Poutrain, COO, Vizimax Inc

"Enspec's approach from the outset was inspiring. They returned a binding quote with 3 days of our initial inquiry and showed diligence and professionalism throughout our contractor qualification process. Once awarded the job, they then produced, installed and commissioned a quality, cost effective solution, safely and within the agreed timeframe and budget. It was simply a pleasure working with them. Since the installation of the STQ MV relay, we have seen an 8 fold reduction in our average peak inrush levels ensuring our facility operates within the ER P28 and our cast resin supply transformer is protected from the mechanical shock loading associated with high inrush levels."
