Microgrid

Profit and the New Normal

Delivering value in a zero-growth market.

Disruptive technologies and resource shifts are changing the utility business model. Market factors are driving companies toward four possible paths.

Goldman Sachs Funds $500 Million for U.S. Rooftop Solar Leases

SolarCity raised lease financing from Goldman Sachs to fund more than $500 million in solar power projects ­– an estimated 110 MW in generation capacity – for homeowners and businesses. The agreement was initiated in 2012 and expanded per its initial terms at the end of April. Solar City says the combined lease financing is the largest of its kind announced in the U.S. for homeowners’ rooftops. About 26 MW has already been deployed under the lease program. 

U.S. Army and Lockheed Martin Commission Microgrid at Fort Bliss

U.S. Army and Lockheed Martin officials commissioned the first U.S. Department of Defense (DoD) grid-tied microgrid integrating both renewable resources and energy storage at Fort Bliss, Texas. The project was funded by the DoD’s Environmental Security Technology Certification Program. The Fort Bliss grid-tied microgrid is designed to reduce overall greenhouse gas (GHG) emissions and energy costs while providing the capability to operate independent of the electric utility grid when needed to provide energy security.

Economy of Small

How DG and microgrids change the game for utilities.

Energy microgrids have emerged as more than just a curiosity. The technology is improving, costs are falling, and developers are lining up to build projects. How will microgrids overcome the substantial challenges that stand in their way?

Old School Microgrid

Resilience depends more on determination than technology.

A brutal storm ripped through southwestern Minnesota in April and snapped 2,000 power poles. Worthington Public Utilities kept the lights on with a seat-of-the-pants microgrid.

No Going Back

Free markets are not a fad.

Half-hearted deregulation hobbles the forces of supply and demand before they can get out of the gate.

Peaceful Coexistence

Independent microgrids are coming. Will franchised utilities fight them or foster them?

Despite offering a range of benefits, microgrids are proving to be controversial—especially when non-utility owned microgrids seek to serve multiple customers. The biggest battles are taking place in the realm of public policy. But utilities that pursue collaboration rather than confrontation are finding interesting opportunities for profitable investment.

Fortnightly speaks with Amory Lovins about the evolving role of conservation, competition, and distributed resources in the energy industry.

'Resilience'

A new watchword for the industry and its regulators.

If the concept of resilience—including cyber and physical security—had been baked into the industry’s culture from the beginning, the energy grid might look a lot different from what it does today.
