As a part of the DISTRIBUTECH International digital providing, D-TECH Plus, Jennifer Runyon had a dialog with a panel of consultants regarding applicable tariff constructions for the combination of microgrids.

The session was based mostly on a recently-published whitepaper co-authored by two of the panelists, Jared Leader, Manager of Industry Strategy at SEPA, and Paul DeMartini, Managing Partner at Newport Consulting, exploring the strategic and sensible issues of microgrid tariff design.

The panel examined the significance of and necessity for a strategic information to allow utilities to discover the scope, aims, forms of microgrids, in addition to operational and tariff fashions out there.

Most utilities have completely different views on behind-the meter microgrid growth or distant microgrids. It’s subsequently necessary to make sure inner and exterior training for all stakeholders, so everyone seems to be on the identical web page.

Jeremy Donnell, Microgrid Policy & Pricing Strategy at PGE, emphasised that definitions are important, one thing PGE discovered whereas engaged on a entrance of the meter multi buyer microgrid in California.

The venture highlighted the significance of utilizing standarised definitions and using inner change administration to adapt to a brand new manner of doing issues.

Marc Asano, Director of Advance T&D Planning at HECO, elaborated on the significance of participating stakeholders to outline microgrids. “Once these definitions are established there are fewer misunderstandings.”

Microgrid terminology should be established, he stated, regardless that it might differ throughout jurisdictions, particularly as we transfer from behind the meter to multi buyer situations.

Asano additionally harassed the significance of defining roles and tasks, particularly as some utilities undertake a joint coordinating mannequin or partnership mannequin – making certain resilience inside communities.

Paul DeMartini, Managing Partner at Newport Consulting, spoke with the panel about key strategic issues when formulating a microgrid tariff. These included:

  • If the microgrid makes use of the utility belongings, the utility ought to be answerable for these belongings, making certain security and compliance of operations;
  • Tariff fashions might be decided by multi accomplice preparations between the utility and for instance third celebration microgrid builders;
  • Multigrid situations will differ in response to situations and jurisdictions;
  • Understanding the connection dynamics in island versus blue sky mode and what occurs to clients current tariffs or the transition backwards and forwards between each modes;
  • In phrases of the resilience companies that would affect the state of affairs, by way of contracts between the microgrid developer, clients and the utility.

For instance, PGE is at the moment exploring various kinds of distant microgrid setups, particularly because the utility strikes to spice up wildfire resiliency. The microgrids have a tendency to incorporate a single buyer or a small cluster of shoppers, and the utility stays accountable to ship vitality to that buyer regardless that they continue to be islanded. This sort of system gained’t want a completely new tariff to help it.

These are the forms of nuts and bolts points to think about when structuring the tariff, in addition to dealing with of interconnection processes, various kinds of service agreements, and compensation mechanisms.

As outlined within the whitepaper, there are perceived gaps within the multi consumer tariff construction and laws is looking for this to be addressed, filling the gaps in current guidelines and tariffs. To learn the whitepaper go to the SEPA web site.
