Interconnection
A solar system can't go in unless the rules for grid connection are fair and streamlined.
DESCRIPTION
It's simple. If you want to connect a solar panel to the grid, first you have to know the rules, aka the "interconnection procedure." But in too many places, this interconnection procedure is overly complex or expensive. Worse yet, in many areas it's not specified at all, meaning that installers don't know what they're getting into.

The first concern should be for the safety of the grid and the workers who service it. This has been thoroughly and repeatedly studied in numerous jurisdictions throughout the US, and a common set of principles has evolved to protect safety while still giving generators the certainty they need.

The same way it's possible to write one set of rules for connecting a telephone, it's possible to write one set of rules for connecting small generators. More than 10,000 small solar systems in California, and 3,000 in New Jersey, have been connected with safe, simple, streamlined interconnection standards.

In fact, the relevant technical standards have been completely established in conservative engineering documents by bodies like UL and the IEEE.

What remains is the process of interconnection – making sure that the fees, timelines, and penalties are fair to small generators. Without transparent principles, small generators can be kept off the grid with excessive studies, interminable timelines, or excessive fees.

Each of the rules below has been extensively reviewed by utility engineers, small generator advocates, and others in open public proceedings. Even the most complex "network" grids in large cities can be accommodated by these general rules. There is no more need to re-launch these negotiations in every state than there is to have different phone jacks in Maryland than you do in Missouri.

When developing these types of standards, there are certain key principles to keep in mind:

Keep fees fair – Bigger, more complex systems should pay bigger fees; small systems require almost no effort to connect and can be reviewed cheaply. In any case, the fees for applications, studies, and any necessary equipment must be carefully laid out in rules beforehand so that clean energy investors know the score.

Allow large systems for large loads – It makes sense for safety to keep clean generators matched to their loads. But a shopping mall can absorb a lot of solar power without the grid seeing one bit. Too many states arbitrarily limit the size of customer generators that can be used, no matter the load they serve. Systems of at least 2 megawatts in size should be permitted with appropriate loads.

Different rules for different sizes – A 1 kilowatt home solar system puts out as much power as a microwave oven takes in. A 1 megawatt solar system can power an entire Wal-Mart. The best interconnection standards "tier" applications so that each faces the right technical standards.

Specify timelines – An application that is not acted on for several weeks may as well have not been acted on at all.

Standardize and simplify forms – The smallest generators should even be able to make all necessary applications and agreements on one simple form.

Best Practice
Best Practice – IREC
The Interstate Renewable Energy Council's model rules build on the solid base of the New Jersey standards and add the latest best practices from other states. Recently, Delaware has elected to adopt standards in line with the IREC model.
Model Rules pdf
Good Practice – FERC
The federal agency that makes sure the grid stays up put out these 2006 standards to serve as a model that can be used nationwide. It's not as up to date as IREC or NJ, and too conservative in some areas, but it's a workable model for small generators.

Good Practice – Colorado
Effectively a state adaptation of the FERC standards.
Colorado Regulations pdf
Any of these regulations can be made into law with relative ease – for instance:
"Within 90 days of the effective date of this Act, the Commission shall [revise / adopt] standards for the interconnection of customer generators having a generating capacity of 2 megawatts or less [code citation may be necessary] to be compatible with the model rule MR – I2005 of the Interstate Renewable Energy Council."
