BERN TWP., Pa. -

A Berks County company is thinking big when it comes to expanding.

EnerSys is building a 70,000 square foot addition in Bern Township and adding 100 new jobs.

"It is a very exciting moment. The company continues to grow and prosper and we are at a point where we have run out of space in our existing facilities," said Dick Zuidema, EnerSys executive vice-president.

EnerSys is a company that manufactures industrial batteries.

Employees and community members gathered at its facility on Route 183 in Bern Township to commemorate the ground breaking of its new addition.

"This building is all about our growth. It is all about us continuing to expand and grow our business," said Steven Weik, EnerSys vice-president of global operations engineering.

The 70,000 square foot addition will expand the company's global headquarters. The addition will give EnerSys more office and lab space.

It will have to hire 100 new employees, something economic development officials say is necessary in Pennsylvania.

"It is companies like this that are creating the private sector jobs that make Pennsylvania competitive and viable," said Carolyn Newhouse, Deputy Secretary of the Department of Community and Economic Development.

The company is aiming to expand its revenue from $2.5 billion to $4 billion in 2018.

"When there is courage and there is vision and there is strong leadership in companies in Pennsylvania, our communities thrive and Pennsylvania is competitive," said Newhouse.

The new addition will cost $14 million.

The state gave EnerSys a $500,000 Pennsylvania First Program grant and $300,000 in Job Creation Tax Credits.
