The intermittent nature of much renewable energy (such as wind and solar) presents both system and transactional challenges. Systemic challenges include dynamic integration, short-term firming, and integration with capacity margin criteria. These challenges also arise in the negotiation and documentation of short and long-term power sales agreements. W&T attorneys have significant experience with such issues in both centralized and bilateral markets; we advise market operators regarding capacity valuation, trading organizations regarding new energy products to support intra-hour integration and subsequent hours firming, and individual market participants regarding bilateral firming arrangements.

Renewable energy also presents unique challenges interconnecting to transmission grids. W&T attorneys have significant experience in these matters both with respect to interconnections with traditional utilities and within regional transmission organizations.
