Distribution Optimization: Ready for Takeoff

Part 2: Key choices on the way forward.

Integrated Distribution Planning (IDP) – much like its bulk power system cousin, Integrated Resource Planning (IRP) – provides a useful starting point for regulators and utilities to begin thinking about how to optimize the distribution system.

Piggybacking on the Grid

Why net energy metering is unfair and inefficient.

While customers may have reached a “net zero” threshold on energy, they are a large net negative on very expensive grid services.

Making Friends with Solar DG

Better to compete from within than fight from afar.

Utilities should embrace distributed solar generation, offering O&M, aggregation, or marketing services, rather than lament a lost business model.

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. 

Facing Facts About Solar

Distributed solar might be a game changer, but at what cost?

My friend Reggie recently asked me for advice about installing photovoltaic (PV) panels on the roof of his boathouse on the river. It has no electricity now, but he wants just enough PV to power a few lights, an automatic garage door opener, and the occasional power tool. I told Reggie the same thing I tell everybody who asks me about rooftop solar: it's exciting but still expensive. Then Reggie explained why I was wrong.
