NOC (NaturEner Operating Center), the epicenter of our operations, has recently deployed GE’s “full suite” E-Terra redundant utility grade Energy Management System (EMS). Operating 24/7, our WECC/NERC certified platform delivers a full suite of services required to integrate NaturEner USA’s portfolio of assets.

Scheduling and balancing capabilities and services include:

NaturEner USA's wind-only Balancing Authorities, NaturEner Power Watch, LLC and NaturEner WindWatch, LLC, have provided stable and robust support to NaturEner USA’s energy integration activities since 2008 and 2012 (respectively). The NOC works day and night to maximize its output and deliver high value generation products in a reliable and compliant manner.

NaturEner USA has prototyped and deployed our products and services for over eight years. We are proud and optimistic as we lead the charge in building a clean energy future for the next generation.


We take an active role in the communities and environments we operate in. Our environmental and community stewardship programs go above and beyond what is required: We believe in investing in the land and in the people who make NatureEner possible.

Avian Conservation Program

From adaptive design to extensive voluntary biomonitoring, NaturEner USA has proven itself as an industry leader in conservation. We go above and beyond to protect local raptor populations, and we’ve developed extensive monitoring and conservation programs for eagles, bats and waterfowl at all our sites.

Our objective with every wind farm is to site, design, construct, and operate in an environmentally sustainable manner by avoiding or minimizing any adverse impacts to wildlife and their habitats. We aim to understand the natural conditions of each unique site. We solicit input from governmental and naturalist organizations as our conservation programs grow and evolve.

Landowners and Community development

Through partnership with NaturEner, landowners enjoy financial, environmental, and social benefits

Our team has a successful history of working with landowners to develop and operate wind farms throughout North America. NaturEner USA’s projects are both environmentally and financially beneficial. We are committed to developing positive and trusting partnerships with landowners that will last for the lifetime of each energy project.

Local communities thriving

Local communities enjoy new opportunities and great benefits from our renewable energy projects. In all our projects, NaturEner USA works together with community members to develop renewable energy solutions that benefit us all.

The benefits of our renewable energy projects extend to the local towns, counties and states where we work. We create new jobs, improve roads and other infrastructure, contribute to local tax jurisdictions, and provide new business opportunities for local retailers and service providers.

Strong community relations and open communication are fundamental to the success of our work. From the beginning of each project, our teams keep stakeholders abreast of their progress and foster an open dialogue with community members to address concerns and expectations.

Our Leadership

  • José María Sánchez Seara

    Prior to joining NaturEner USA ten years ago, José María held executive management positions in the European energy sector, where he was responsible for strategy, growth and development, engineering, sales, and overall business relationships. He was a founding partner for Proyectos De Cogeneración, S.L., DeWind Iberia S.A. and Proyedeco Ingeniería y Servicios, S.L. He began his career two decades ago at Deutz Energy in Spain.

He earned his degree in Naval Engineering from the Polytechnic University of Madrid. Since 2010, he’s been a member of the YPO (Young Presidents Organization), SF Bay chapter.

    “Wind power could supply more than several times current worldwide consumption of electricity and total global use of energy in all forms,” he says. “And levelized cost of renewable electricity is cheaper than fossil fuel-based electricity, even without considering some other benefits. Time to move on.”

  • Candace Saffery Neufeld

    Chief Operating Officer
