Corporate renewable energy procurement: an overview

Reading Time: 4 minutes

In today’s current era of renewable energy targets, action is not just limited to political entities such as the federal government, states or individual cities. In fact, many corporations are getting in on the act by promoting corporate sustainability programs or contracting directly with renewable energy developers to build solar and wind farms specifically for their company. As the solar and wind industries continue to grow, corporate renewable procurement and targets will play a substantial role in driving renewable energy to greater and greater heights.

microgrids

What are microgrids and how do they work?

Reading Time: 4 minutes

As more and more customers express interest in solar plus storage on EnergySage’s Marketplace, many do so with the same intended purpose: resiliency. When the grid goes dark, these solar shoppers want to ensure that they are on an electric “island” to keep their own lights on, self-generating and storing solar electricity that they can then consume. The solution? Microgrids.

Partially in response to major storm events nationwide, this innovative, if not new, approach is being taken throughout the country to maintain greater reliability and to return power quicker at the local level. By taking the notion of an electrical island from a single home to multiple buildings or an entire community, communities, cities, and organizations are creating microgrids.
