WindStream Technologies Sets Single Month Record

Company Ships Just Under 1 Megawatt of SolarMill^® Products in March

NORTH VERNON, IN — (Marketwired) — 04/01/2015 — WindStream Technologies, Inc. (OTCQB: WSTI) (“WindStream” or the “Company”) announced today that it has had the best single month of shipping in the Company’s history, in March 2015, with shipments capable of producing, in the aggregate, just shy of 1 megawatt (mw) of hybrid renewable energy power. The Company has now shipped its products to 35 countries and has seen the SolarMill^® adopted by residential users, small businesses and municipalities.

“March was a mega-month for the Company” said Dan Bates, President and CEO, “our biggest and busiest month to date, as SolarMills were shipped to Jamaica, India and Nigeria. As the demand for clean energy grows, we believe that WindStream is uniquely suited to provide its products to meet this increasing need.”

WindStream’s North Vernon facility in its current configuration and at full capacity is capable of producing products that can generate approximately 2mw of energy. This equals approximately $4 million of revenue using the Company’s base model, the SM1-2P. As an example of WindStream’ ability to scale its production, the Company built more generators in the last 15 days of March than it had in the previous 5 months of production, and the Company is increasing its capacity to fulfill its current order backlog.

The Company’s core product, the SolarMill^®, is a scalable, hybrid, wind and solar renewable energy device that has resonated with customers both on and off grid. The design of the SolarMill^® allows it to be easily installed and generate useable clean energy without the need for expensive and cumbersome processes like other renewable energy technologies.

The Company anticipates that volume will continue to increase as its second manufacturing plant in Hyderabad, India becomes fully operational in April 2015.

There are now more than 1,000 WindStream systems deployed in Jamaica, India, Nigeria and elsewhere in the world. These SolarMills are serving both residential and commercial properties, and they are operating both on and off the power grid.

“This was a major milestone for WindStream” said Travis Campbell, the Company’s COO. “Meeting the challenges of scaling our facility for the increase in sales and demand forced us to get better at every aspect of the manufacturing process and our team rose to the occasion. I could not be prouder.”
